Hello,
I want to bind the DataObject.Pasting event of a TextBox with the EventToCommandBehavior to a command of the viewmodel:

However, in the example above, the message "DataObject.Pasting event cannot be found" appears. What is the right way to bind the pasting event?
Thanks a lot
Christoph

Hi,

When I drop a GridView on a new window, I get an exception, and the designer shows the following error. How do I avoid this?

Hello , I'm trying package"Telerik.UI.for.Wpf.NetCore.Xaml.Trial" v2020.2.617, when I start to learn chartview,The VisualStudio can't build the project.

Here's the message:

"D:\Work\CSharp\PersonalProject\TelerikDemo\TelerikWpfApp1\TelerikWpfApp1\MainWindow.xaml(79,22): error MC3074: XML 命名空间“http://schemas.telerik.com/2008/xaml/presentation”中不存在标记“AreaSeries.DataPoints”。 行 79 位置 22."

Please give me a hand.

Hello,

I have some kind of selection problem.

Drag selection didn't work at items outside the viewport.

Attach an image that can help you understand the content.

When there are 5 items and they are long enough to be out of viewport, drag them from the top to the bottom to select only the items in viewport and not the items outside.

However, a full selection is made through a full selection command, such as ctrl+a.

How do I select items outside of viewport? Is there any other way but to be selected on the behind code?

I have a GridView and I am using a CellStyleSelector to set the background color of different cells depending on some conditions and it is working fine.

Now I would like to be able to select a row and change the background color of the whole row, right now it is only working on the cells that are not using the CellStyleSelector.

I have seen that I can change the color of the selected row, like this:

But how can also be changed on cells with CellStyleSelector?

Hello,

I have a RadWindow with 5 buttons, with only one or two of them visible at a given time. I would like, for example, that the Escape keyboard key has the Close action when in view mode and the Cancel Changes action when in edit mode.

To do this I use the tk:RadWindow.ResponseButton="Cancel" attribute for both buttons.

The problem is that the RadWindow logic is to look for the first button with this attribute and simulate a Click event on this button. I suggest that you make a small change to this behavior, to look for the first visible and enabled button with this attribute. By Visible, I mean with the Visibillty property set to Visible.

I know that I can process the Escape key myself, but why reinvent the wheel?

Best regards

Goo day.

How can I trigger the Add New Row on the DataGrid using a separate button. Are there any sample program available for this?

I also need to have a Button to trigger Edit and Delete of a selected row.

Thank you.
