Hello,

Try the following JS.

JS:

<script type="text/javascript">
function OnClientClick()
 {
    var grid = $find('<%=RadGrid1.ClientID %>');
    var count = grid.get_masterTableView().get_selectedItems().length;
    if (count == 0)
    {
      //your code
    }
   else
    {
      //your code
    }
 }
</script>

Thanks,
Princy.

Thanks very much,

and I have other problem: I use  button Control <asp:Button runat="server" ID="btnValidation" OnClientClick="javascript:return OnClientClick(); " Text="[text validation]" />

<script type="text/javascript"> 

function OnClientClick()

 {

    var grid = $find('<%=RadGrid1.ClientID %>');

    var count = grid.get_masterTableView().get_selectedItems().length;

    if (count == 0)

    {

      return false;

    }

   else

    {

      return true;

    }

 } 

</script>

When I click check a checkbox=> it means OnClientClick function will return TRUE;
BUT there is NO ACTION it doesn't work (not post back to server).

Even thought, I changed:
<asp:Button runat="server" ID="btnValidation" OnClientClick="javascript:return true; " Text="[text validation]" />

it doesn't work too.

I don't know is there any problem when using TEELRIK??
If I don't use TELERIK it works normal!

Please help me to do it.

Thanks alot
