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.

Hi there

This is a very impotent control in our company.
However, we need to implement a spell checker as you already have in RTF.

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 control should be customizable so you can place also a content different than an image as in the WPF native splash screen support (https://docs.microsoft.com/en-us/dotnet/framework/wpf/app-development/how-to-add-a-splash-screen-to-a-wpf-application).

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.

    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).

When a document is imported (for example from XAML) and then exported to DOCX or RTF, the fields lose their formatting. The issue is not observed if the document is just created.
Workaround: Change the fields display mode of all fields in headers/footers just before the export:
private void UpdateHeadersFooters(RadDocument document)
{
    foreach (Section section in document.Sections)
    {
        if (section.Headers.Default.Body != null)
        {
            this.UpdateFields(section.Headers.Default.Body);
        }
 
        if (section.Headers.First.Body != null)
        {
            this.UpdateFields(section.Headers.First.Body);
        }
 
        if (section.Headers.Even.Body != null)
        {
            this.UpdateFields(section.Headers.Even.Body);
        }
 
        if (section.Footers.Default.Body != null)
        {
            this.UpdateFields(section.Footers.Default.Body);
        }
 
        if (section.Footers.First.Body != null)
        {
            this.UpdateFields(section.Footers.First.Body);
        }
 
        if (section.Footers.Even.Body != null)
        {
            this.UpdateFields(section.Footers.Even.Body);
        }
    }

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
