Hi,

Please try the following Javascript to prevent user from typing particular characters.

ASPX:

<telerik:radcombobox id="RadComboBox1"runat="server" allowcustomtext="true"></telerik:radcombobox>

Javascript:

function pageLoad()
{
    var combo = $find("<%= RadComboBox1.ClientID %>");
    var input = combo.get_inputDomElement();
    input.onkeydown = onKeyDownHandler;
}

function onKeyDownHandler(e)
{
 if (!e)
 e = window.event;
 var code = e.keyCode || e.which;
 //do not allow any of these chars to be entered: !@#$%^&*()
 if (e.shiftKey && code >= 48 && code <= 57) {
     e.returnValue = false;
     if (e.preventDefault) {
         e.preventDefault();
     }
 }
}

Thanks,
Shinu.
