Looking for way to handle Paste into RadTextBox

[Stephen]

Greetings,

I have an ASP.Net Framework 4 application on Windows 7, using C# for the backend coding, that I need to be able to trigger off of a paste event in a RadTextBox control.

Scenario is there are two text box controls. If the user enters text into one text box, the other text box needs to be cleared. I have handled this for the case when the user types new text into either of the text boxes, but that solution (using the ClientEvents-OnKeyPress event handler) does not work for a paste operation.

Is there a solution to this that I have not found? If so, any assistance would be appreciated.

Thanks.

Steve

Specifics:
- ASP.Net Framework 4
- Windows 7 SP 1
- IE 9.0.8112.16421
- Telerik WebUI VSExtensions 2011.02.712.0
- Preferred Programing Language: C#

Hello Stephen,

Wouldn't handling the OnValueChanged event work for you? This event should be raised regardless of how the text is entered into the RadTextBox.

I hope that helps.

Unfortunately, no, it doesn't work that way.

Here is a snippet from the online documentation about the OnValueChanged event handling:

"The event occurs immediately after the control loses focus and its value has been updated, but before the server-side TextChanged event."

This is what I have in place, but until the text box loses focus for any reason the event is not triggered to clear out the other text box.

Thanks for the suggestion though.

Hi Stephen,

You could  try implementing a solution similar to the demo here:

http://msdn.microsoft.com/en-us/library/ms536955(VS.85).aspx

You can subscribe to onpaste like this:

< telerik:RadTextBox onpaste="OnPaste()" />

< script type="text/javascript">
 function OnPaste()
 {
 // .........
 }
< /script>

All the best,

Hi,

Generally, the onpaste event is supported in all major browsers:

You can check the attached web site sample for a practical implementation.

I hope this will prove helpful.
