Question

Asp.Net: trap Enter button event during datagrid edit processing

Asked by: HStrix

Hello experts,
In my vb.net web application I created a datagrig with an edit button and several editable columns.
After clicking the edit button I'm able to edit columns.
If this has been done I can press the ENTER key on my keyboard and a click routine gets activated;
I believe the last Z-Index of a clickable button is used.
Now I want to trap that event and transfer it to the OK button,
which (and a cancel button) is shown after clicking the edit button
in a line of the datagrid instead of the edit button.
Does anyone know how I can manage this?

  Thank you for any help.

I have just the thing...

Andy Smith's default buttons control will trap the enter key and use it to click whichever button you set it to.

Thank you reaves, that sounds good for 'normal' buttons.
But how about the buttons in a datagrid?
Sample:
---
<asp:datagrid id=myname ...>
  <Columns>
      <asp:EditCommandColumn ButtonType="LinkButton" EditText="Edit" CancelText="Cancel" UpdateText="OK"
               ItemStyle-Width="8%">
     </asp:EditCommandColumn>
     <asp:TemplateColumn
     </asp:TemplateColumn>
     ...
     <asp:BoundColumn ... />
  </Columns>
</asp:datagrid>
---
I'm defining the edit and its subsequent OK and Cancel buttons as described above.
I do not understand how to establish the connection to that OK button.
Is the control able to do this as well?

The following code (inserted between the head tags)
solves my problem:
-----
<script language="javascript">
<!-- begin-of-javascript
//
var message  = "Pressing the ENTER is not supported!";
// Ignore hitting the ENTER key:
function myEnter() {
  if (document.all) {
    if (event.keyCode == 13) {
      //alert(message);
      return false;
    }
  }
}
//
document.onkeydown=myEnter;
//
// end-of-javascript -->
</script>
