How do I set displayed text in DataGridBooleanColumn (defined in C#, not XAML) to desired strings, rather than the defaults?

Documentation of this Column type is unhelpful and has no examples for either CellContentFormat (which it notes is Framework dependent) or CellContentTemplate.

In the more general ColumnsCellTemplates document there is a Boolean CellContentTemplate in XAML, but not in C# and I have found translating from the XAML to C# is yet to work for me.

No way in Andoid to actually select a RadListPicker popup item.

My mobile use of RadListPicker displays as a popup (expected -- that is the default). but I never see the buttons that should be at the end of the list, which itself can be fairly long. The documented Footer Template property appears to never have been implemented -- it is not in the metadata for RadListPicker, RadPickerBase, PickerContentView, RadContentView, etc.

I would like to use Telerik's Maui SDK Demo project to see if a workaround exists, but it only builds for Windows. In Android I get the error:

"Error NETSDK1130 Microsoft.Graphics.Canvas.winmd cannot be referenced. Referencing a Windows Metadata component directly when targeting .NET 5 or higher is not supported. For more information, see https://aka.ms/netsdk1130"

As this does not happen in the Cryptocurrency sample (which does not use a ListPicker), I assume SDK has some Windows-specific code that needs replacement.

Even so, the real need is for a GestureRecognizer in the Spinner Control, which does not currently support them. Right now I can tap all I want on an item and the Selected Event never fires. That is understandable, in a way, as documentation says selection only occurs when user "confirms" his choice. Without either a GestureRecognizer or a footer, there is no current way to do that in popup.

Does telerik support ImageButton on MAUI project?

Hey Team,

Does telerik support ImageButton on MAUI project? I created a telerik button and set image as content and no text, but I saw it did not show full image.

<telerik:RadButton Grid.Row="2" 
                               ImageSource="restbutton.png"
                               Padding="0"
                               Margin="0"
                               x:Name="PrimaryTelerikCommandButton" 
                               VerticalOptions="Center"
                               WidthRequest="24"
                               HeightRequest="24"
                               HorizontalOptions="Center"
                               BackgroundColor="{DynamicResource TelerikButtonBackgroundColor}"
                               Command="{Binding ClickCommand}">
</telerik:RadButton>

you can see the Image size is 24*24.

and result like below:

Thanks

How can we change the PlacementTarget for popup in the codebehind?

If you create the Popup with code, you have to explicitly set the PlacementTarget property. Any example?

When the Popup is declared in XAML and you want to center it, attach it to the Page element and set its Placement property to "Center". How to attach it to Page?

Telerik needs to please provide ticket submission for MAUI errors

I realize Telerik MAUI is in pre-release, just as MAUI itself is. But after so many months of pre-release, surely it would be helpful to the coding team to know of errors still missed.

Here's one simple example of a missed error: TabViewItem has a HeaderText property that really ought to be bindable in xaml, but is not. (Doesn't hurt to have it there, but does not do anything.) So it has to be set in code behind. Easy workaround but should not be necessary.

Another: I like the new RadEntry's Completed Event -- works well. But RadEntry still has an Unfocused Event that worked in earlier versions, but not now. If an event is available, it should be implemented or else made unavailable. No one likes to write a lot of xaml only to find events do not fire! (Personally, I can get by just fine with Completed.) When I moved from pre-release 4 to 6 I had to rewrite hundreds of events from Unfocused to Completed as the former had quit working.

Etc.
