Hi ,
I am working on RadGrid and I need to get a alert on GridHyperLinkColumn click in the radgrid just as I get by using GridEditCommandColumn while editing the record if the user is not authorised to edit the data.Otherwise how can I give the Command Name for the GridHyperLinkColumn so that i can handle it in the codebehind.
Thanks,
h@r!.

Hello Hari,
You can achieve this by finding the HyperLink in the GridHyperLink column and set its "onclick" attribute.

Hi Princy,
Thanks for the Reply :)
But it is not working in my scenario.Let me explain my case clearly.
I am having Grid with values binded using GridBoundColumn.And I need to check the values in the GridBoundColumn and if they are null I need to alert when the user clicks Edit link.
like
and I need to check if Company="" and if the user clicks the Edit which is a GridHyperLinkColumn I need to give an alert as 'User unauthorised' and if Company!="" then he can proceed to edit the row.
Hope it explains the case clearly.

Hello Hari,
You can do that validation with the cell value of GridBoundColumn from client side by using its ColumnUniqueName. Check out the following code snippet.
