We recently updated to version 2024.1.312.  After the update, we get an exception (see stack trace below) or freezing with many of our RadToggleSwitchButtons.  It seems to only affect the ones that are backstage in a RadDataForm.  I found https://feedback.telerik.com/wpf/1645011-buttons-nullreferenceexception-when-setting-ischecked-of-radtoggleswitchbutton-before-the-control-is-added-to-the-visual-tree, but the workaround suggested there doesn't work for us, even if we leave the animations enabled.

Hi
Please find my below code showing the celledittemplate

                <Button.Visibility>
                        <con:ConverterBindableBinding Binding="{Binding IsSearchAccountVisible,UpdateSourceTrigger=PropertyChanged}"

            </Button>
        </Grid>
    </DataTemplate>
</telerik:GridViewDataColumn.CellEditTemplate>

If I click the "SearchButton" on first click the event does not fire, the click event fires if I click it second time.
If I remove the SmartSearchRadAutoCompleteBox  control & only keep the SearchButton then it works ok.

Can someone give me code snippet having multiple controls (one radautosearchbox & one button) in datatemplate of celledittemplate or help me understand what is causing issue in my  Click event

Hello. 
I want to add Custom User control to RadDocument in RadRichTextBox. So I use InlineUiContainer to do that. And add it to paragraph.

And it looks so that I have to define height and width to make it so that it will take correct space in the document layout. If I skip this step then it looks like it takes zero width and height.
Looks strange. Because of course I don't know physical size of element in advance. As workaround I can do some "magic" with Loaded event and extract size of UiElement once it was rendered. And it works. But definitely it looks like a dirty code. 
I believe I miss something. Please help me. What am I doing wrong here? :)

By the way when I need to add InlineUiElement  to standard WPF RichTextBox it does all calculations of size by itself.

As you can see in the picture the button just gets cut. It only does this if the hight is less than 38

<Grid.RowDefinitions><RowDefinition Height="Auto"/><RowDefinition Height="70"/><RowDefinition Height="*"/></Grid.RowDefinitions><Grid Grid.Row="1" >
<telerik:RadDropDownButton HorizontalAlignment="Right" Margin="0,0,20,10" Background="#EFEFEF" Padding="5,0,0,0"
	Height="24" BorderThickness="1" BorderBrush="LightGray" CornerRadius="5"  telerik:StyleManager.Theme="Windows11" >
<telerik:RadDropDownButton.Content>

Hi,

Is there a way for a telerik radbutton to only show the image that's chosen for a button? 

Opacity is at 100% yet i am still seeing the actual button outline and grey fill/background around my buttons.

See below image.

Thanks

I have a RadBusyIndicator and inside it I have several other controls; the structure is bit complex and there are several DB operations are performed in that and while performing that DB operations we are setting IsBusy property of RadBusyIndicator as per progress to true and false. But after invoking this property keyboard focus is shifted to the main window which is not the correct behavior. 

I want my focus on the current control from where I am calling some commands, and it is doing some DB operations.

I have gone through the below solution, but it is not much helpful in my case because the structure of my code is bit complex and I don't want BusyIndication invoked every five seconds as mentioned in this link - "how to restore the focus"

Any help regarding this is much appreciated.
