Hello Medac,
It is not clear whether you want the textbox value to
only appear uppercase or to actually
be uppercase. Check out the following example, which demonstrates both. The text-transform CSS style is used to make the textbox value appear uppercase, while the ValueChanging event is used to actually transform the value. No need to use keystroke events for that.
<%@ Page Language="C#" %>
<%@ Import Namespace="System.Data" %>
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
<script runat="server">
protected void radtxtCarrierComments_TextChanged(object sender, EventArgs e)
{
Label1.Text = (sender as RadTextBox).Text;
}
</script>

<style type="text/css">

{
text-transform:uppercase;
}
</style>
</head>

<telerik:RadTextBox ID="radtxtCarrierComments" runat="server" CssClass="upper" AutoPostBack="true"
OnTextChanged="radtxtCarrierComments_TextChanged">
<ClientEvents OnValueChanging="MyValueChanging" />
</telerik:RadTextBox>
<script type="text/javascript">
function MyValueChanging(sender, args)
{
args.set_newValue(args.get_newValue().toUpperCase());
}
</script>
<br /><br />
textbox value: <asp:Label ID="Label1" runat="server" />
</form>
</body>
</html>
All the best,
