I have the same issue with Enter.
by default Enter is refreshing the rad window content (don't know why). If focus is inside the window, enter is closing it by my "cancel" button:
<asp:Button runat="server" ID="btnCancel" Text="Anuluj" Width="120px" OnClientClick="closeDisplayContractors(true); return false;" CausesValidation="false" />
btnCancel is the last element on the page. If I will add a dummy button after btnCancel, the dummy button is called instead of btnCancel.
this is a quite annoying thing as I've got a search text box in that window:
<telerik:RadTextBox runat="server" ID="txtSearchBox" EmptyMessage="(podaj wartość)" Width="100%">
<ClientEvents OnKeyPress="shouldSubmitSearch" />
</telerik:RadTextBox>
This box i taking a OnKeyPress and on enter, should preform search, but instead its still closing a window.
Please help.
Cheers,
Jakub G
