Hello,

I'm getting a Dictionnary exception when using the Import function of the RtfFormatProvider in a Task.

Here's an example of the code that is run:

I'm loading items in parralel using Tasks.

Those items have a property bound to a RichTextBox and I'm deserializing the RTF string in a RadDocument through a RtfFormatProvider.

The code worked fine when I didn't use the Tasks and called the function in a synchronous way. However, since I switch to Tasks, I get the follwing error on the Import method:

"An item with the same key has already been added"

(PS: The code has been tested with the latest release of UI for WPF)

I don't suppose the RtfFormatProvider has a hidden ConcurrentDictionary somewhere that could solve this? :)

Do you know if what I'm trying to acheive is possible?

I am saving the layout using the savelayout method on the docking control.

This works fine (although i have no pane titles but that is another question) until I float panes on external monitors (I have 3). 

When I do this and I use the save layout method I get an error 'Managed Debugging Assistant: 'FatalExecutionEngineError'. The runtime has encountered a fatal error. The address of the error was at 0x65bf395f, on thread 0x4548. The error code is 0x80131623. This error may be a bug in the CLOR or in the unsafe or non-verifiable portions of user code. Common sources of this bug include user marshaling errors for COM-interop or PInvoke, which may corrupt the stack.

My code (in the Window closing event) is:

MemoryStream stream = new MemoryStream();
DockMain.SaveLayout(stream);

stream.Seek(0, SeekOrigin.Begin);

StreamReader reader = new StreamReader(stream);

var layout = reader.ReadToEnd();

Then i persist layout to a file.

Can you please assist.

Hi,

Based on this ( https://www.telerik.com/forums/cannot-implicitly-convert-type-radwindow-to-window )

i tried to get the HostWindow in an mvvm + prism with prismapplication.

But it failed in CreateShell() the Shell is a RadWindow and is created but there is no HostWindow retuned and so it will not work.

Maybe because in PRism the changed the return Type to Window ( i think it was DependencObject before ) 

but so what can i do to return the Shell here ? 

thanks br

thomas

protected override void RegisterTypes(IContainerRegistry containerRegistry)
{
    containerRegistry.RegisterSingleton<ShellWindow>();
}
 
protected override Window CreateShell()
{
    var shellwin = Container.Resolve<ShellWindow>();
    var appwin = Window.GetWindow(shellwin);
    return appwin;
}

I want to be able to toggle between the different orientations of the schedule view. I have a property bound to my view model but this doesn't seem to be working. I have tried different variations. Can someone tell me what i may be missing?

Hello,

when I start a brand new Telerik WPF project, and want to add a RadGridView component to the main window, the following error message shows:

Method not found: 'Telerik.Windows.Controls.SortingState Telerik.Windows.Controls.GridViewColumn.get_SortingState()'.

I just upgraded to the latest Telerik WPF version.

Please advise.

Thx

How do you turn off the animation when the filter popup expands and/or collapses as it opens? For other Rad controls, such as RadTreeView, settings

 telerik.IsAnimationEnabled="False" 

works. Putting this in the XAML of the RadGridView does not work, however.

Any help would be appreciated. Thank you

Hi Progress Telerik,

When I type the date 01 09 18, the tooltip suggests 18 Sep 2001.

But when I type 01 09 2018, the tooltip suggests 01 Sep 2018.

I want the suggestion date to be 01 Sep 2018 when I type 01 09 18.

I'm using the CultureInfo en-US and date format dd MMM yyyy.

Kindly assist on how to achieve the same.

Thank You,

With Best Regards,

Muhammad Azhar Shah

Hello,

I have problem with RadRibbonViewBackstage. My window shell contains two regions in separate rows. In First region I registered view containing RibbonView with RibbonViewBackstage. In second i defined statusbar view. When ribbonView's backstage is closed everything looks fine (First region and second shares window space). Problem appears when I open backstage. Backstage View is always taking whole window space and my status bar dissapears under. Is there any option to make Backstage same size as region in which i is defined so it will leave space for bottom status bar?

Thanks for your help :)
