I want to set the focus on an embedded textbox in a GridViewDataColumn

I tried on the AddingNewDataItem event the following with no success:

var grid = e.OwnerGridViewItemsControl;
grid.CurrentColumn = grid.Columns[1];

I've tried sending keys on  the RowEditEnded event. Nothing works.

 

 

 

Hi,

I was combine shapes in code. And combined shape add to toolbox.

But Drag to diagram. then, Not Available.

I want to draw custom shape. And Save to Xml.

Thanks.

is there anyone that had experienced this? I recently updated our 2014 controls to 2021 controls.

Although I haven’t experienced it myself, our customers are experiencing an odd issue when they type with the rad rich box text editor

 The app simply freezes. Our editor does extend the base radrichtextbox control and has its own style so perhaps there is some property that behaves differently now?

Hi,

Is there a quickest way to hide center connectors of shapes? Because sometimes when you'd like to drag a shape and it ends up creating a self-connected connection. That might be annoying to the end users.

Thanks!

I would like to know what's the equivalent of `OnSourceInitialized` for the `RadWindow`?
My need is to disable the WPF hardware acceleration for the window because of some calls to python with CUDA 
causing WPF thread rendering issue.
How does one disable hardware acceleration in wpf? - Stack Overflow
Thank you,

I'm trying to create a chart series with a gradient fill but for some reason the serie isn't showing on the sceen.
When i use a solidcolorbrush i have no issues but with the LinearGradientBrush it's not working.

The LinearGradientBrush is created correctly so i seems so kind of display issue?

What do i need to do to make this work? Is there any example i can check to see how this should work?

Hi telerik,

I've created .Net 5 project , however  telerik controls can't be seen on xaml designer,  although wpf default controls are shown well.  On running, all controls are seen and working without problem.

With the help of many threads regarding this subject , I  found your reply how to remove designer cache and set the extension option,etc.  While I did all steps as you said, no success yet.  

My situation is as follows, 

 - telerik 2021.2.615 and  vs2019  16.10.2 installed.

 - projects are created as WPF 5.0 project, not by tererik wpf template because it only support till .net 4.5.

    Projects target is 'ANY CPU'.

 -  NoXaml dlls are copied to solution folder from installed directory, and all projects referenced  those.

    Double checked that no cross referenced dll exists between NoXaml and Xaml dlls.

 

During checking, I found that toolbox configuratIon  supports only .net 4.5. as attached image. 

Does that mean that I missed something ?  so designer failed to load telerik controls ?

 

TIA

Kang

If I invert the order of selection the error don't raise.

In the figure: first I select the node in yellow, then I click in the arrow in red

 

Hello.

When using RadAutoCompleteBox, an error occurs in the debug output if the tab is changed.

[System.Windows.Data Error: 26 : ItemTemplate and ItemTemplateSelector are ignored for items already of the ItemsControl's container type; Type='RadWatermarkTextBox']

The issue has been around for a long time. I heard it's a wpf timing issue.

I also found this issue on the feedback portal.
https://feedback.telerik.com/wpf/1351336-a-binding-error-is-printed-in-the-output-on-start-up-for-elementname-watermarktextbox

Are you still using the above post and can't fix it?

 

Thanks.
