Hello Dominik,

Set AutoPostBack="true" for your TextBox, this will change it's behavior to make PostBack.

Thank You Vasil,

Yes, when I set AutoPostBack=true then LoadPanel work with Enter key.
But it work also, when I move cursor to another TextBox on the Form.
I'm looking for how to invoke LoadPanel ONLY after Enter key, but not after focus change.
If the only way for working Enter key on TextBox with LoadPanel is enable AutoPostback, how I can disable PostBack when TextBox change focus to another TextBox on the Form ?

Dominik,

Then you could handle the client OnKeyPress event of the RadTextBox and change the AutoPostback depending on the keyCode of the last pressed key.
<script type="text/javascript">
  function ChangePostBackSetting(sender, eventArgs)
  {
    sender.set_autoPostBack(13 == eventArgs.get_keyCode());
  }
</script>
<telerik:RadTextBox runat="server" ID="RadTextBox6">
  <ClientEvents OnKeyPress="ChangePostBackSetting" />
</telerik:RadTextBox>


Kind regards,
