After installing the WPF software I was not able to open any project in VS 2017 without it hanging.

 

In the end I removed the VS integration and was able to resume development.

 

It was the only Telerik component I had installed. I can't find the version number but it was the latest of the website as of 17th Oct 2019.

 

Can you explain why this happened?

when use the RadTransitionControl's SlideAndZoomTransition effect for the RadTabControl, the radComboBox Multiple Selection will lost in the  tabItem。

the  radComboBox data is from the mvvm binding,after change the tabitem,the Multiple Selection become single selection.

the RadTabControl's style is following:

           ...

           <ControlTemplate x:Key="TabControlTemplate" TargetType="telerik:RadTabControl">

Requirements:

- Multiple screen RDP-Session with option "Show windowcontents while dragging" turned off.

- RadTabbedwindow with AllowTransparency = false (might not be necessary)

 

When dragging a maximized TabbedWindow to a different screen into maximized mode, it is allways maximized on the primary screen.
Dragging it on the target screen so that it is not maximized and then clicking maximize works.

The issue only appears when the mentiond setting in the RDP-Session is turned off.

Good morning,

at the moment we are using third parts libraries to show RTSP/MPEG video flow in our app.

After the new RadWebCam control release, we hoped it was possibile to specify another video flow for example from IP camera.

May I suggest to implement the possibility to specify a different stream source in the RadWebCam?

Or maybe to implement a new control called "RadPlayer" that is similar to RadWebCam but permits to set a custom stream?

Because snapshot/video recording feature of RadWebCam are very interesting also for a RTSP flow.

 

Thank you

Best Regards 

Enrico

Current SDK Sample code supports only WPF 40.

Adding support for wpf45 will make more convenient way to work with Samples.

Sample dode can include new wpf 45 features

    For the Pivot control,if the group header width greater than the first column width,when start the app,
the first column width will expand the group header width(like the attach file "Start.png"),
instead of it self width (like the attach file "ResizeColumn.png",it is our desired),moreover,when resize the column width,like the attach file "ResizeColumn.png",
then Collapse,the result like the attach file "Collapse.png",but not our desired the group header width(should not cover the text).

As we now have support for Webcams with RadWebcam-Control how about supporting Twain? But not the old version, instead the platform independent newer Twain-Direct. There is already C# Source Code under MIT-License available: https://github.com/twain/twain-direct. I think this could be used in Xamarin and WinForms, even ASP.NET also...

Most commonly the exception message is "Input file or data stream does not conform to the expected file format specification".

This appears because of the glyphs font used in the different controls.

To work this around you can use two approaches:

  • Update to Windows 7 SP2.

  • The second option is to download the UI for WPF source code, find the TelerikWebUI.ttf file and convert it to .otf using a third party tool (like FontForge for example). Then use a reflection to replace the font file, before the application startup. For example:
    RadGlyph.GetRegisteredFonts();
    var dictionary = typeof(RadGlyph).GetField("registeredTypefaces", BindingFlags.NonPublic | BindingFlags.Static)?.GetValue(null) as Dictionary<string, Typeface>;
    dictionary?.Clear();
       
    RadGlyph.RegisterFont(new FontFamily(new Uri("pack://application:,,,/WpfApp3;component/TelerikFont/", UriKind.RelativeOrAbsolute), "./#TelerikWebUI"), "TelerikWebUI");
    In the code snippet, "WpfApp3" is the assembly name of your project, and "TelerikFont" is a folder in your project, containing the converted font file. You can call this code in the OnStartup override of App.xaml.cs. Or before the InitializeComponent() call in the main window's constructor.

See attached picture together with these steps.

  1. select a item in the list
  2. import multiple other items in one go -> the last imported item is marked as selected (this is OK), the previously selected item is no longer marked as selected (this is OK).
  3. SHIFT select the first item of the ones imported in step 2 -> the items between the last imported item and the first imported item are selected, but the item that was selected in step 1 is now also selected...

 

Thanks in advance!

Bart

Hi Team,

 

We have a business case, where we build a spreadsheet with collapsable groups and subgroups. Our customers wanted to have an overview about the group totals on each group and expand and collapse the groups on demand (because it's also possible in Excel).

 

So, it would be awesome, if you could extend your spreadsheet component with that feature as well.

 

Thank you

Currently when you highlight a row in the child GridView, the ParentRow becomes highlighted. It would be really nice to have an option so that the ParentRow would be selected when a row in the child GridView is selected. This should work recursively selecting the ParentRow all the way up the hierarchy.

I've written a workaround, but it isn't pretty.

Please add this functionality. :)

 

My case involves a three tier hierarchical GridView (each in single select mode). If I select a row in a third tier GridView, then I want its ParentRow to become selected on the second tier and the second tier's ParentRow to become selected on the first tier. Hopefully that makes sense.
