[edit: I meant "Modal" Editor and not "Model" editor in the title but I can't update]

Hi,

 

as I know you can use a custom modal editor with an Editor attribute that is declared on a property. Is it possible to use a modal editor with a programmatic approach with PropertyDefinition? I have a dynamic class where I do not have the possibility to declare attributes on properties. On the PropertyDefinition class there is an EditorTemplate property. I managed to use this. But only "in cell" and not modal. Is that possible?

Best regards,

Oliver

I have been fighting this for hours and have tried a number of things to no avail. The selector is hit, returns the correct values, but grid is showing no change. I have distilled the issue down to a simple project and removed anything that might be interfering. I am attaching the whole solution here (.NET 6).

I have to be doing something wrong but very simple. Any help is appreciated.

Hello,

I'm using the Callout control and host a ListBox as content. Basically works as expected. It is possible to select an item in the list and scroll the list with mouse wheel.

Problem is using the scrollbar of the hosted ListBox. When it is used in any way (click, press and move mouse to scroll) the Callout closes. The expected behavior would be that I can scroll the list using the scrollbar and select an item. Callout should stay open till closed by code or focus lost (e.g. click somewhere outside Callout control).

Attached is a small example that shows that behavior.

 

I tried already to disable autoclose and control (dis)appearance manually. With that approach I have the problem that I don't know how I get informed when there was a click outside Callout control (to close it manually), hence it stays open.

 

Thanks and Regards

Philipp

Hi,

We have switched over from using WPF's built in ContextMenu's to RadContextMenus and we are using Prism Delegated commands.

We have set the "tag" property of the UI element (that has the RadContextMenu attached to it) to an ElementReference to the containing window so that we can then use UIElement.Tag to get back to the Window to then bind to it's PrintCommand.

This all works well, however if we open the ContextMenu from code behind using contMenu.IsOpen = True then the UIElement property is not being set to anything so the command cannot be found.

Is there a different way we should be bindiing the RadContextMenu items to the view commands?

Thanks,

 


<telerik:RadContextMenu  DataContext="{Binding Path=UIElement.Tag, RelativeSource={RelativeSource Self}}" InheritDataContext="False">
   <telerik:RadMenuItem Header="Print" InputGestureText="Ctrl+P"
                                       Command="{Binding PrintCommand}" />
</telerik:RadContextMenu>

After reading through the documentation, I was wondering if there was a way to create your own mode for "DistinctValuesSearchMode" other than the four provided.

What I'm trying to create is a mode where users can input separations, such as commas, to filter out more results from the selected column.

Ex:

Hello,

I just changed all project references from referencing the installed dll's (Progress\Telerik UI for WPF R1 2023\Binaries\WPF45) to nuget version (e.g. Telerik.Windows.Controls.GridView.for.Wpf.Xaml). Unfortunately, this results in some controls not redering at all any more.

I see this especially at <telerik:Label>, <telerik:Button> and <telerik:GroupBox> (using xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation")

If I instead use the standard WPF <Label> in the exact same XAML file, the label gets rendered.

Is there anything special one has to apply/change/update if changing from the "installed" version of Telerik for WPF to the nuget based version?

 

Any help or idea much appreciated,

Sebastian

                      <Button Command="{Binding Path=MyCommand}">
                      </Button>
              </StackPanel>
        </telerik:RadTabControl.AdditionalContent>
       <telerik:RadTabControl.Items>
             <telerik:RadItem>
                  <!-- Here everything works just fine -->
              </telerik:RadItem>
       </telerik:RadTabControl.Items>
    </telerik:RadTabControl>
   </Grid>
</UserControl>
