is it possible to convert a xaml-file to an image file of some sort?
I have some xaml-files describing a GUI, and a want to get a 'preview' of them at runtime.
Greets,
Jürgen
maybe the RenderTargetBitmap can help you ?
the idea is to render a visual element into a bitmap...
this blog post describes the use

In a UWP, I use the "CollectionViewSource" in a xaml file, and when I want to bind the source for it, it doesn't work and the error information is
Input string was not in correct format
What can I do for solving this problem ?
You have to parse the json file into a collection from the corresponding type, then bind to that collection.
Hope it helps you out.
I want to define a number of xml formatted strings in resource file and use the strings in qml code. Is it possible? How to do it? I would be really appreciated any example.
As I know there is no way to store strings in resource file. But you still do that in another way.
First way: create language file with qt translation tool. As bonus you can store string in several languages.
Using in QML is very easy:
Text {
text: qsTr("myTextId");
}
See that link for more info.
Second way: store each string in different resource file.
But in this case you need to extend QML with C++ plugin to get ability to read files.
See that link for more info.
How do I provide a custom data as a DataProvider for ImageTilesLayer on a mapControl in XAML file?
I am new to WPF and DevExpress. I was trying a few examples given in the DevExpress documentation site.
Link: How to Load Image Tiles from Another Source
In the example, How to Load Image Tiles from Another Source given in their site, the DataProvider for a ImageTilesLayer is assigned in the code behind file.
Is it possible to mention the same DataProvider in the XAML instead of the code behind file?
You can assign the ImageTilesLayer.DataProvider property in XAML as follows:
<dxc:MapControl>
<dxc:ImageTilesLayer>
<dxc:ImageTilesLayer.DataProvider>
<local:CustomMapDataProvider/>
</dxc:ImageTilesLayer.DataProvider>
</dxc:ImageTilesLayer>
</dxc:MapControl>
P.S.
For more information about XAML properties syntax, see XAML Overview (WPF)-> Property Element Syntax MSDN article.
For more information about custom types in XAML, see XAML and Custom Classes for WPF.
Coding Horror, I would suggest you first read the tutorials given by DevExpress.
Link to the tutorials is below.
https://documentation.devexpress.com/#WPF/CustomDocument10682
It explains the different layers on map control.
Once you have read that, read on how to load images from different source
https://documentation.devexpress.com/#wpf/CustomDocument11174
In the code, instead of giving a url, change it to a local image folder where you have cached all the map tiles.
public class CustomTileSource : MapTileSourceBase {
const string roadUrlTemplate =
#"http://{subdomain}.tile.openstreetmap.org/{tileLevel}/{tileX}/{tileY}.png";
You can know more about caching at https://documentation.devexpress.com/#WPF/CustomDocument12205
Is it possible to capture the screen rendering of a QML Component and save it to an image file? I would like to drive a Component through several different states, and capture its visual appearance for documentation purposes, without having to do screen/window captures.
Yes, you could set up your state transitions to call QWidget::grab then save it to a file through QPixmap.
If you need an example of how to set up your code to call QWidget::grab take a look at this answer: How to take ScreenShot Qt/QML
It's important to replace QPixmap::grabWidget with QWidget::grab because QPixmap::grabWidget is now obsolete. Once you have the QPixmap from QWidget::grab follow the documentation in QPixmap to save to the format you'd like such as jpeg, png, gif.
Here are some links to the documentation to help you out.
QWidget::grab
QPixmap
QPixmap::save
With Qt 5.4 it is now made easier with grabToImage - this method resides on all QQuickItem objects.
EDIT
It's worth mentioning that the item you call grabToImage() on must be a child of a top-level Window item container
On the safari browser, the standard <asp:Menu> doesn't render well at all. How can this be fixed?
Thanks for the advice, it led me into the following solution;
I created a file named "safari.browser" and placed it in the App_Browsers directory. The content of this file is shown below;
<browsers>
<browser refID="safari1plus">
<controlAdapters>
<adapter controlType="System.Web.UI.WebControls.Menu" adapterType="" />
</controlAdapters>
</browser>
</browsers>
As I understand it, this tells ASP.NET not to use the adaptor it would normally use to render the control content and instead use uplevel rendering.
You can use ControlAdapters to alter the rendering of server controls.
Here's an example:
http://www.pluralsight.com/community/blogs/fritz/archive/2007/03/27/46598.aspx
Though, in my opinion it might be equal amount of work to abandon the menu control for a pure css one (available on many sites).
Oooof - was hoping it would be a simmple case of adding a browserCaps item in web.config with appropriate values or similar...
The best and simplest solution I've found for this problem is to include this bit of code in your page_load event.
if (Request.UserAgent.IndexOf("AppleWebKit") > 0)
Request.Browser.Adapters.Clear();
