Is it possible to control the output of a webpartzone in sharepoint.
We would like not to have tables.
What are you doing to handle this ?
We haven't done that. But we did similar stuff to override behavior of other SP controls.
First of all you need to learn the conception of ASP .NET Control Adapter.
The main idea is that it's possible to override behavior of any control. So, in this case you can override Web Part Zone Render method and put your logic there.
The only issue is that you need to register your control adapter for specific browser and use .browser files for that. To workaround that create your own HttpModule and handle BeginRequestEvent. There you can register your adapter for all browsers, e.g.
var browser = m_Application.Context.Request.Browser;
if (browser == null)return;
if (!browser.Adapters.Contains(webPartZoneTypeName)){
browser.Adapter[webPartZoneTypeName] = strongNameOfYourAdapter;
}
Hope this will help.

I am developing my own eclipse editor and need to switch between different contexts for key binding. Currently I am doing the context activation/deactivation manually upon part activation.
This page
https://help.eclipse.org/mars/index.jsp?topic=%2Forg.eclipse.platform.doc.isv%2Fguide%2Fworkbench_advext_contexts.htm says:
If you are activating a more specific Context within your part (either
View or Editor) you can use the part site service locator to active
your Context. The part's IContextService will take care of activating
and deactivating the Context as your part is activated or deactivated.
It will also dispose the Context when the part is disposed.
It seems like that is just what I want. But the page did not say how. Can anyone give me a hint what a 'part site service locator' mentioned in the text is and how to use it?
I would interpret the text so that you should use the service locator of the site that corresponds to your (editor) part. In the following example, part references your editor. By obtaining the context service from the part's site, you get a child context service for that particular part in wich you can activate a specialized editor context.
IContextService contextService = part.getSite().getService( IContextService.class );
contextService.activateContext( "your.editor.context.id" );
After digging through Eclipse code, here's my answer to my own question.
First thing first, it is JUST enough to invoke
IContextService contextService = part.getSite().getService( IContextService.class );
contextService.activateContext( "your.editor.context.id" );
anywhere after init(where you get PartSite), just as #Rüdiger Herrmann mentioned in his answer.
AND(here's my finding) NOTHING ELSE need to be done.
Eclipse will automatically activate/deactivate the context when part is activated /deactivated, just as described in the text I refer to. In addition, when the part site is disposed, all context will be disposed.
If you are interested in how, here's more digging.
Activate/Deactivate
When we invoke getSite().getService(IContextService.class), what we get is an instance of SlaveContextService.
When we call activateContext(String contextId) on it, our request will be automatically translate to a request with a default expression ActivePartExpression.
From it's name we can easily guess that this expression will check whether a part is active and do some changes. The changes it does can be seen at ContextService.UpdateExpression.changed. Here's the code(ContextService:124-128)
if (result != EvaluationResult.FALSE) {
runExternalCode(() -> contextService.activateContext(contextId));
} else if (cached != null) {
runExternalCode(() -> contextService.deactivateContext(contextId));
}
Whenever Eclipse context changes(activate/deactivate part will trigger context change), UpdateExpression.changed will be invoked and check whether the target part is still active, then activate/deactivate the context accordingly.
Dispose
In SlaveContextService.dispose, all context registered through it will be disposed upon the service's dispose.
I have a UWP application.
And i have a need to change locale on the fly, so i have this for language changing:
Windows.Globalization.ApplicationLanguages.PrimaryLanguageOverride = language.FourDigitCode;
ResourceContext.GetForViewIndependentUse().Reset();
ResourceContext.GetForCurrentView();
But there is a problem that system features language doesn't switch ( only after application relaunch ) how can i fix it?
Here is an example:
Now i run this code:
Windows.Globalization.ApplicationLanguages.PrimaryLanguageOverride = "lv-LV";
ResourceContext.GetForViewIndependentUse().Reset();
ResourceContext.GetForCurrentView();
The UI gets localized, but system features still remain unlocalized:
But when i restart the app, all is OK:
Any ideas how can i fix it?
I'm afraid there is no fix for this and what you've seen is by design. Ref Remarks of PrimaryLanguageOverride property:
When you set the PrimaryLanguageOverride, this is immediately reflected in the Languages property. However, this change may not take effect immediately on resources loaded in the app UI. To make sure the app responds to such changes, you can listen to the QualifierValues property on a default resource context and take whatever actions may be needed to reload resources. Those requirements may vary depending on the UI framework used by the app, and it may be necessary to restart the app.
For your scenario, a restart is needed. I'd suggest that you can add a tip to tell users to restart the app and also a button to close the app like what used in News App.
And to close the app, we can call Application.Exit method like the following.
Application.Current.Exit();
Maybe page reloading can fix it? Try to re-navigate to the same page.
Found the example below here.
//like this
private bool Reload(object param = null)
{
var type = Frame.CurrentSourcePageType;
Frame.Navigate(type, param);
Frame.BackStack.Remove(Frame.BackStack.Last());
}
// or like this
private bool Reload(object param = null)
{
var frame = Window.Current.Content as Frame;
frame.Navigate(frame.CurrentSourcePageType, param);
frame.BackStack.Remove(frame .BackStack.Last());
}
Is the source for Windows Store (WinRT) UI controls publicly available? We would like to extend some of the controls and not have to start completely from scratch, like we can for SL and WPF. Googling and looking through SO doesn't turn up anything for Windows 8.
Thanks!
So unlike WPF, [WinRT-XAML] controls are written in C++/CX.
But, it sounds not so much like you want the source code as much as you want to derive from existing controls and extend or override their functionality. You know you can do this, right? It's easy enough and sounds like you will get the results you are asking in your question.
Something like this:
public class MonkeyTextBox : TextBox
{
public new string Text
{
get
{
return "Always Monkeys!";
}
set { /* do nothing */ }
}
}
This is my custom TextBox wherein I have replaced the base implementation of Text with my own. Granted, I hope your custom controls are better. Anyway, you can do this with almost every control, and you can add your own properties and events. Make sense?
Reference: http://blog.jerrynixon.com/2013/01/walkthrough-custom-control-in-xaml-isnt.html
But to answer your question: no, we have not released the source (yet). Hopefully, that will save you the time looking for it. Maybe someday we will - maybe.
Best of luck!
I have a program that is getting pretty big and it is a pain to find everything through all the functions and classes.
I am trying to break it up into other files based on their method.
Some of these functions have calls to others in the main class. I changed most my functions from private to public to access this. I had problems calling certain code created windows so importing mainwindow helped that.
My last problem is editing the mainwindow ui from one of the module files. I want to make sure im on the right page before i continue breaking it up. My only guess is that anything they updates the ui should be left on the main class.
Thanks
The only code in your form class should be code that talks to other classes and updates the UI based on data from other classes.
Depending on your application, the form class might handle change events from other classes to update the UI or pass user input to other classes in Change or Click events.
A couple options:
Use callbacks into the your main window.
Create events for when you need the form updated. Your program logic raises the events, and your main window class can consume them.
I'm working on an app in the Silverlight 4 RC and i'm taking the oppertunity to learn MEF for handling plugin controls. I've got it working in a pretty basic manor, but it's not exactly tidy and I know there is a better way of importing multiple xap's.
Essentially, in the App.xaml of my host app, I've got the following telling MEF to load my xap's:
AggregateCatalog catalog = new AggregateCatalog();
DeploymentCatalog c1 = new DeploymentCatalog(new Uri("TestPlugInA.xap", UriKind.Relative));
DeploymentCatalog c2 = new DeploymentCatalog(new Uri("TestPlugInB.xap", UriKind.Relative));
catalog.Catalogs.Add(c1);
catalog.Catalogs.Add(c2);
CompositionHost.Initialize(catalog);
c1.DownloadAsync();
c2.DownloadAsync();
I'm sure I'm not using the AggregateCatalog fully here and I need to be able to load any xap's that might be in the directory, not just hardcoding Uri's obviously....
Also, in the MainPage.xaml.cs in the host I have the following collection which MEF puts the plugin's into:
[ImportMany(AllowRecomposition = true)]
public ObservableCollection<IPlugInApp> PlugIns { get; set; }
Again, this works, but I'm pretty sure I'm using ImportMany incorrectly....
Finally, the MainPage.xaml.cs file implements IPartImportsSatisfiedNotification and I have the following for handling the plugin's once loaded:
public void OnImportsSatisfied()
{
sp.Children.Clear();
foreach (IPlugInApp plugIn in PlugIns)
{
if (plugIn != null)
sp.Children.Add(plugIn.GetUserControl());
}
}
This works, but it seems filthy that it runs n times (n being the number of xap's to load). I'm having to call sp.Children.Clear() as if I don't, when loading the 2 plugin's, my stack panel is populated as follows:
TestPlugIn A
TestPlugIn A
TestPlugIn B
I'm clearly missing something here. Can anyone point out what I should be doing?
Thanks!
I think most of what you are doing is fine. Although ObservableCollections do support notifications of individual elements being added and removed, MEF doesn't take advantage of this. In your case it will simply clear the collection and then add all the plugins. Since you are using OnImportsSatisfied for the change notification, you don't even need an ObservableCollection. You could just use an IEnumerable for your import.
To add flexibility in downloading different xaps, I would expose a service in your container that can be imported and that provides the functionality to download a xap given a url. Then any component in your container can trigger a download, and the url to download can come from whatever source you deem appropriate.
