Hi everyone,

Does anyone how to add a javascript confirmation popup to a link button?

<asp:ButtonColumn HeaderText="Del" ButtonType="LinkButton" Text="Del"
CommandName="Delete" />

Thank you
Maz.

Hi Maz,

The easiest way is to convert it to a template column, give it an ID and
then add the JavaScript when the item is created. The code below should get
you started. Let us know if it helps?
