This code used to work in WSS 3.0 / MOSS 2007 in FeatureReceiver.FeatureActivated:
using (SPLimitedWebPartManager limitedWebPartManager = Site.GetLimitedWebPartManager("default.aspx", PersonalizationScope.Shared)) {
ListViewWebPart listViewWebPart = new ListViewWebPart {
Title = title,
ListName = list.ID.ToString("B").ToUpper(),
ViewGuid = view.ID.ToString("B").ToUpper()
};
limitedWebPartManager.AddWebPart(listViewWebPart, zone, position);
}
I'm trying to convert to SharePoint 2010 and it now fails with:
System.ArgumentException: The specified view is invalid.
at Microsoft.SharePoint.SPViewCollection.get_Item(Guid guid)
at Microsoft.SharePoint.WebPartPages.ListViewWebPart.EnsureListAndView(Boolean requireFullBlownViewSchema)
at Microsoft.SharePoint.WebPartPages.ListViewWebPart.get_AppropriateBaseViewId()
at Microsoft.SharePoint.WebPartPages.SPWebPartManager.AddWebPartInternal(SPSupersetWebPart superset, Boolean throwIfLocked)
at Microsoft.SharePoint.WebPartPages.SPLimitedWebPartManager.AddWebPartInternal(WebPart webPart, String zoneId, Int32 zoneIndex, Boolean throwIfLocked)
at Microsoft.SharePoint.WebPartPages.SPLimitedWebPartManager.AddWebPart(WebPart webPart, String zoneId, Int32 zoneIndex)
Interestingly enough when I run it from a unit test it works, it only fails in FeatureActivated. When I debug with Reflector it is failing on this line:
this.view = this.list.LightweightViews[new Guid(this.ViewGuid)];
list.LightweightViews only returns one view, the default view, even though list.Views returns all of them. When running from a unit test LightweightViews returns all of my views. I have no idea what LightweightViews is supposed to mean and I'm running out of ideas. Anyone else got any?
To make it work, just do the following:
Do not set the viewguid property of the listviewwebpart object (leave it blank)
call the AddWebpart method
It will generate a new viewguid associated to a new hidden view.
Then if you want to customize this view, retrieve it from the list and customize it.
Hopefully no one ever has this problem or even sees this question. In the unfortunate event you get the same problem I have no specific solution. It eventually just started to work for me (8 hour later). I can tell you what I did right before it started working and hopefully it will help:
I went in through the UI and set the view that I was trying to set the list view web part to as the default view. I believe that's what fixed it and I have no idea why.
Some other notes on the problem:
I create all my lists and views through code
RunWithElevatedPrivileges did not help
Instantiating a new SPWeb in feature activated did not help
Setting ListViewXml = view.HtmlSchemaXml instead of setting ViewGuid made it not crash but the view was wrong when this code executed in FeatureActivated but correct when executed in a unit test.
Best I can do, sorry. If you're having this problem, good luck!
After reading this and this articles I found even more easiest solution.
When you add listviewwebpart to an any page, webpart automatically creates new hidden view in list, which is associated with this webpart (you can check it in SharePoint Manager).
When you switch view for listviewwebpart throw UI, it simply get copy of fields from selected view and push it in his hidden view.
All you need is get this view by ID, add\remove necessary fields and update view. Something like this:
var wpMngr = web.GetLimitedWebPartManager(workspaceWeb.Url + "/default.aspx", PersonalizationScope.Shared);
var attendeeListViewWebPart =
(ListViewWebPart)wpMngr.WebParts.Cast<WebPart>().FirstOrDefault(w => w.Title == Lists.AttendeesList);
var list = workspaceWeb.Lists[Lists.AttendeesList];
var view = list.Views.Cast<SPView>().FirstOrDefault(w => w.ID.ToString("B").Equals(attendeeListViewWebPart.ViewGuid, StringComparison.OrdinalIgnoreCase));
view.ViewFields.DeleteAll();
view.ViewFields.Add...
view.Update();
According to articles, you cann't update ViewGuid property for listviewwebpart.
I have been fighting with this today also.
For some odd reasons the code that you provided works for some cases but not in others.
I haven't had time to investigate more about that but what I can say is that if you are willing to use the XsltListViewWebPart (which is the replacement of the ListViewWebPart in SharePoint 2010), you will get rid of this annoying "bug".
I have just tested in myself.
Hope it helps!
I was getting this same error with an XsltListViewWebPart:
Exception: System.ArgumentException: The specified view is invalid.
at Microsoft.SharePoint.SPViewCollection.get_Item(Guid guid)
at Microsoft.SharePoint.SPList.GetView(Guid viewGuid)
at Microsoft.SharePoint.SPList.GetView(String viewGuid)
at Microsoft.SharePoint.WebPartPages.BaseXsltListWebPart.EnsureView()
at Microsoft.SharePoint.WebPartPages.BaseXsltListWebPart.get_AppropriateBaseViewId()
at Microsoft.SharePoint.WebPartPages.SPWebPartManager.AddWebPartInternal(SPSupersetWebPart superset, Boolean throwIfLocked)
at Microsoft.SharePoint.WebPartPages.SPLimitedWebPartManager.AddWebPartInternal(WebPart webPart, String zoneId, Int32 zoneIndex, Boolean throwIfLocked)
at Microsoft.SharePoint.WebPartPages.SPLimitedWebPartManager.AddWebPart(WebPart webPart, String zoneId, Int32 zoneIndex)
Since SPList.GetView is a public method, I tried it in Powershell using the Guid from my new view. It worked fine.
I figured out that the problem was the context. I had been creating my view right before the ViewGuid assignment. When I moved the creation of my view outside of the SPLimitedWebPartManager, the code ran without any errors:
SPView view = CreateHiddenView(list);
using (SPLimitedWebPartManager manager = file.GetLimitedWebPartManager(PersonalizationScope.Shared))
{
try
{
XsltListViewWebPart webpart = new XsltListViewWebPart();
webpart.ListName = list.ID.ToString("B").ToUpperInvariant();
webpart.TitleUrl = list.DefaultViewUrl;
webpart.WebId = list.ParentWeb.ID;
webpart.Title = list.Title;
webpart.ViewGuid = view.ID.ToString("B").ToUpperInvariant();
manager.AddWebPart(webpart, "Right", 1);
}
finally
{
manager.Web.Dispose();
}
}

this is the first time I'm posting a question here; I have searched and searched and searched here and other places and I cannot seem to get any results. I'm using VISUAL BASIC 2015 in Visual Studio 2015. QUESTION: I need to have a modal window/popup from a particular website remain INSIDE the web browser control/window on my form (WebBrowser1); when a particular link is clicked, the modal window/popup jumps out of the form and directly to the user on their screen. I have to keep this popup inside because there are other links to be clicked on that popup, but if it jumps out of the web browser control, no code will work since it's outside WebBrowser1. What I have found is code for older versions, and not 2015; if anything I can even add WebBrowser2 to have the popups/modal windows appear there if possible, just as long as I can code them to keep clicking inside the form. PLEASE HELP! THANK YOU!
window.open (and a click on <a target="_blank"> etc) can be handled via the NewWindow2 event. Hans already pointed out how to do that in comments. NewWindow3 works too, but need at least Windows XP SP2.
As for window.showModalDialog, it is a bit tricky. IE has IDispatchEx (wrapped as IExpando in .Net) implemented on scripting objects so you replace the methods and properties with your own implementation. But window.showModalDialog shows a dialog that has arguments and return values, you need to override those properties in the modal dialog you create too. The code looks roughly like tis:
void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
//skip events from frames
if(WebBrowserReadyState.Complete!=webBrowser1.ReadyState) return;
if(FindLoginFormOnPage()) {DoLogin();return;}
if(IsWelcomePage()){NavigateToPage1();return;}
if(IsPage1()){SubmitFormOnPage1();return;}
if(IsPage1FormResult()){
var document=webBrowser1.Document.DomDocument as mshtml.ITMLDocument2;
var expando =(IExpando)document.parentWindow;
expando.RemoveMember(expando.GetMethod("showModalDialog"
,BindingFlags.Instance | BindingFlags.Public);
expando.AddMethod("showModalDialog"
,new ShowModalDialogDelegate(this.MyShowModalDialog));
}
......
}
object MyShowModalDialog(string url, object varArgIn, object options)
{
using(FromMyShowModalDialog myShowModalDialog
=new MyShowModalDialog())
{
myShowModalDialog.StartupUrl=url;
myShowModalDialog.DialogArguments=varArgIn;
//omit the code to parse options
//and set dialog height/width/topleft location etc
if(myShowModalDialog.ShowDialog()==DialogResult.OK)
{
//do something on the return value before passing to the scripts
......
return myShowModalDialog.ReturnValue;
}
return null;
}
}
and in the Load event handler of MyShowModalDialog you call something like webBrowser1.Navigate to show the page requested by the parent page.
Now you need to pass the arguments to the webbrowser control on the new form. Do the same as above but replace another property this time.
expando.RemoveProperty("dialogArguments");
expando.AddProperty("dialogArguments")
.SetValue(expando,this.DialogArguments);
This will let the web page access the value passed from MyShowModalDialog and stored in this.DialogArguments.
The earliest you can access the DOM is in webBrowser1_DocumentCompleted. By that time the scipts on the page that read window.dialogArguments are probably already executed and got nothing. After overriding window.dialogArguments, you need to study the script on the page to find out how to revert that. for example, if the page has
<head>
<script>
var oMyObject = window.dialogArguments;
var sFirstName = oMyObject.firstName;
var sLastName = oMyObject.lastName;
</script>
...
<span style="color: 00ff7f">
<script>
document.write(sFirstName);
</script>
</span>
you need to change the values of sFirstName and sLastName then change the innerText property of the span, probably identify via its relationship with a named div or table cell. You can write the necessary changes in a script and call it via HtmlDocument.InvokeScript.
If the page returns a value to its parent, you need to pass it on to your parent form too. Override window.returnValue so when the script writes to window.returnValue it writes to a variable you provided
......
expando.RemoveProperty("returnValue");
expando.AddProperty("returnValue").SetValue(expando,this.ReturnValue);
I use Caliburn.Micro for my Silverlight application.
I have a view/viewmodel to create a new Item.
On the view there is one combobox.
The first time I open the view , fill in all fields, the Item is saved correctly.
The second time I open the view, fill in all fields, all teh values of them are changed in the object, except the value of the combobox, this property of Item stays 0 (it's an integer).
Any ideas why this is? I think the Caliburn framework is doing something weird.
thanks,
Filip
The code to open the view was:
EventAggreg.EventAgg.Publish(new ObjectDetailEvent() { ObjectDetail = new ObjectDTO() });
I replaced it with:
EventAggreg.EventAgg.Publish(new ObjectDetailEvent() { ObjectDetail = new ObjectDTO { LandId = 0 } });
LandId is the property bound to the combobox.
So when this is filled in by default, teh notify works perfect every time.
Here is what I'd like to do :
I have an Silverlight application using navigation frame and MEF. (like this one : http://msdn.microsoft.com/en-us/magazine/gg535672.aspx)
This application consists of a set of buttons. Each button click load a view and its associated ViewModel.
Within theses views, I've a list with items and when I click on each items it refreshs a kind of sub-view in this view.
I'd like to create a navigation system : for example myapp.aspx#view1/2, where 2 is in fact the item clicked in the list. If I click on one of the button, it would load a default item and refresh all the view, but when I click on an item, I wouldn't like to refresh all the view but only certain part of the view (I do not want to create another instance of the view and viewmodel).
My problem is in fact that I would like to get the best pratice to get a reference to an existing view or viewmodel when i'm navigating to this page that has already been loaded (for example from myapp.aspx#view1/2 to myapp.aspx#view1/3)(I plan to do this into the BeginLoad of the ContentLoader class)
If I get the viewmodel, I can do that I want by changing for example the current itemId property which could refresh the view thanks to binding.
Thanks in davance if you have something to propose.
A common approach is to use some form of Messenger to do this type of operation. The item's click could trigger the sending of a message, with the Item attached. The ViewModel in question would be a subscriber, and edit its current settings (ie: it's ItemId, which would trigger the binding refresh).
The most common implementations are usually ones similar to the Messenger service in MVVM Light.
It's fairly easy to roll your own here, though, especially since you're already using MEF. Just create a service to handle the message passing, and import it into both endpoints.
Actually, I would have prefered to use an URI to navigate in my application when I click on an item, but if I use an URI, the entire view is reloading and not the specific part I'd like to.
With the messenger, I won't be able to use navigation with url within the view, I think ? Or else I didn't really figure out what you proposed to me.
The algorithm I would like to take is :
navigate("...asp#MyView1/1")
MyView1 is current view ?
yes then I'd like to get the viewmodel of the current view and change it the ItemId property with 1
no, then the view will be created
And I'd like to implement this algorithm there : (this is the place where the view is instancied for each navigation, in my CompositionNavigationContentLoader class)
public IAsyncResult BeginLoad(Uri targetUri, Uri currentUri, AsyncCallback userCallback, object asyncState)
{
// Convert to a dummy relative Uri so we can access the host.
var relativeUri = new Uri("http://" + targetUri.OriginalString, UriKind.Absolute);
// Get the factory for the ViewModel.
var viewModelMapping = ViewModelExports.FirstOrDefault(o => o.Metadata.Key.Equals(relativeUri.Host, StringComparison.OrdinalIgnoreCase));
if (viewModelMapping == null)
throw new InvalidOperationException(
String.Format("Unable to navigate to: {0}. Could not locate the ViewModel.", targetUri.OriginalString));
// Get the factory for the View.
var viewMapping = ViewExports.FirstOrDefault(o => o.Metadata.ViewModelContract == viewModelMapping.Metadata.ViewModelContract);
if (viewMapping == null)
throw new InvalidOperationException(
String.Format("Unable to navigate to: {0}. Could not locate the View.", targetUri.OriginalString));
// Resolve both the View and the ViewModel.
var viewFactory = viewMapping.CreateExport();
var view = viewFactory.Value as Control;
var viewModelFactory = viewModelMapping.CreateExport();
var viewModel = viewModelFactory.Value as IViewModel;
// Attach ViewModel to View.
view.DataContext = viewModel;
viewModel.OnLoaded();
Thanks.
I'm a complete newbie at Dojo, and Adobe AIR, which is my target. I'm
trying to put some panes into an AccordionContainer like so:
var mainview = dijit.byId("mainview");
var rand = randomString();
var widg = gtd_create_entry_widget(rand)
air.trace(mainview);
air.trace(widg);
mainview.addChild(widg);
"mainview" is my AccordionContainer, and gtd_create_entry_widget() is:
function gtd_create_entry_widget(id) {
var entry = new dijit.layout.ContentPane();
entry.attr("id",id);
entry.attr("title","title "+id);
return entry;
}
The pane shows up in the container, with the correct id and title, and
no errors, however, if I try to add another pane, the next one shows
up too, but I get the error:
TypeError: Result of expression '_7' [undefined] is not an object.
I get the same error if I run
var mainview = dijit.byId("mainview");
mainview.destroyDescendants();
and also, only one pane is destroyed at a time, and I understand this
method should destroy all the children.
I can include full project code if required.
Thanks a lot
Garry
I'm not exactly sure if this is going to fix your problem, but you're supposed to use dijit.layout.AccordianPane (http://www.dojotoolkit.org/api/dijit/layout/AccordionPane.html) with the AccordianContainer.
I'm developing a WP7 app and the application needs to change the icon of a button on the application bar given the state of a request.
I have tried:
if (App.Servers[index].ServerState == "Enabled")
{
DetailsAppBar.btnStart.IconUri = new Uri("/AppBar/appbar.stop.rest.png");
}
else
{
DetailsAppBar.btnStart.IconUri = new Uri("/AppBar/appbar.transport.play.rest.png");
}
This doesn't give me an error in the code, but it can't compile....
any hints to do this is appreciated :)
thanks
ApplicationBar is a special control that does not behave as other Silverlight controls (see Peter Torr's post on the subject). One of the consequences is that names given in XAML to app bar buttons generate fields in code-behind that are always null.
I'm guessing that in your case the btnStart field in DetailsAppBar is set to null, and thus trying to set its IconUri property results in a NullReferenceException being thrown.
To access a button in an application bar, you must instead reference it by its zero-based index in the buttons list. For instance, the code below returns a reference to the third button in the app bar:
button = (IApplicationBarIconButton)ApplicationBar.Buttons[2];
figured it out...
((ApplicationBarIconButton)ApplicationBar.Buttons[2]).IconUri = new Uri("/AppBar/appbar.stop.rest.png",UriKind.Relative);
did the trick :)
