Can this be done?  I have a popup which edits gridview rows. I want to have a gridview on the popup which contains data related to the data being edited. At the moment, the gridview is not appearing. I have tried to the the databind both before and after showing the modal pop and neither method is working.

        btn2Update.Text = "Update"
