Hi,
I wanna replace all TextBlock controls used in RadGridViews in my application with another control.
for example: if is instead of TextBlock, use RichTextBox.
there is any way to do that?
Thanks.

Hi,

There are several different possible approaches to this task. You can create a custom column, overriding CreateCellElement. You can also use the DataTemplate support, by using CellTemplate, or CellTemplateSelector.  If the scenario requires that all TextBlocks should be replaced, I would recommend the custom column approach.
As a side note, I would like to mention that RichTextBox is a very complex control and using it in every cell of RadGridView will significantly affect performance. Can you please share what is your ultimate goal, so that we can discuss an alternative approach if it is possible.

Hi,
The TextBlock have some problem when you type words in different languages.
for example, if you type Arabic word first and after that, you type an English word,
it seems you type English word first.
I fix it using RichTextBox.
So I wanna use this control instead of TextBlock in RadGridView.
Thanks.

Hello,

You can try using a RichTextBox, but if the performance is not satisfying enough, I would suggest that you try using a custom user control that solves the problem. Can you please confirm whether you want to display it in edit, or display mode, as you mentioned that the issue occurs when typing?
