RadGrid Enter key behaviour

[RvdGrint]

Hello,

can someone explain me the RadGrid behaviour on pressing the enter.
I've a radgrid with property AllowSubmitOnEnter is set to false. This causes strange behaviour. Sometimes the Enter Key causes an InitInsert and sometimes it causes an Edit command.
I expect the enter key always to do an update. Can someone tell me how to force this behaviour?

Hello josM,

The AllowSubmitOnEnter property is used to set whether the edit form will be submited when the ENTER key is pressed.

Thanks,
Princy.

Princy,

OK. But is it possible to fire a Custom command on pressing enter in a RadGrid?
In my case I want to load a custom usercontrol on pressing enter on a selected grid row.
So is it possible to catch the Enter press an fire a custom command instead of the 'Edit' or 'InitInsert' the Enter normally fires?

How do you explain that sometimes 'InitInsert' is fired and sometimes 'Edit'?

Regards,

Hello JosM,

Try the following aspx and javascript to catch the Enter key press and to fire a custom command of yours.
aspx:

<ClientSettings>
      <ClientEvents OnKeyPress="OnKeyPress" />
</ClientSettings>

JS:

<script type="text/javascript">
function OnKeyPress(sender, args)
{
 if (args.get_keyCode() == 13)
   {
     sender.MasterTableView.fireCommand("CustomCommand","");
   }
}
</script>

Thanks,
Princy.

Princy,

this works fine if I want to handle the customcommand at the serverside.
I'll catch the customcommand also clientside with:

<ClientEvents OnCommand="GridLedgerCommand" OnKeyPress="GridLedgerKeyPress" />
      </ClientSettings>

function GridLedgerCommand(sender, args) {
  var _command = args.get_commandName();
  var _argument = args.get_commandArgument();

  if (_command == "CustomCommand") {
     ItemClick('LOADCONTROL', '~/UC/FIN/AccountInfo.ascx', 7, 193, '');
    args.set_cancel(true);
  }
}

As you can see I'm calling a function ItemClick which forces a postback:

function ItemClick(sType, sURL, iModuleID, iObjectID, sSessionParams) {
   var _event = sType + '::' + sURL + '::' + iModuleID + '::' + iObjectID + '::' + sSessionParams;
   __doPostBack('ctl00_Main', _event);
}

When debugging the aspx file the eventArgument  of the page.Request is empty. It seems the postback is overrulled somewhere.
Do you have any idea how to fix this.

Regards,
  Jos.

Princy,

I used this thread 
And defined a OnKeyDown event on the grid  like:

function GridLedgerKeyDown(sender, args) {
  if (args.keyCode == 13) {
    args.cancelBubble = true;
    args.returnValue = false;

    if (args.stopPropagation) {
      args.stopPropagation();
      args.preventDefault();
    }

    ItemClick('LOADCONTROL', '~/UC/FIN/AccountInfo.ascx', 7, 193, '');
  }
}

And this solved my problem.

Thnx,

Regards, 
  Jos.

Hi 

<script type="text/javascript">

function OnKeyPress(sender, args)

{

 if (args.get_keyCode() == 13)

   { args.set_cancle(true);

//     sender.MasterTableView.fireCommand("CustomCommand","");

   }

}

</script>

The Above code is working to stop the enter event. but i need to get the selected row functionality. I have a link button in my item template. any response for this please.
