Filtered Textbox

[Andy Ho]

Hi,

Is there any way to use the RadTextbox as a Filtered Textbox (like AJAXCONTROLTOOLKIT) where we can define the valid characters of input?

Thanks

Hello Andy,

You can achieve this funtionality by attaching the OnKeyPress event to RadTextBox. Check for the keycode in the event handler and cancel the event based on requirement.

An example is shown in the documentation. I hope this would useful for you.
OnKeyPress

Thanks,
Princy.

Princy,

First of all, thanks for your reply.

I understand that the onkeypress event will work. Just want to know if there is a property that we can set, such as :

ValidChars="ABCDE". I think it is a quite useful feature.
