GridView Buttons not Working?

In my experience, the most common reason for Buttons in a GridView not working is:

That data is being bound to the GridView during the postback.

In other words, the code looks something like this:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

Me.gvMyGridView.DataSource=getData()

Me.gvMyGridView.DataBind()

End Sub

When it should look like this:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

If Not IsPostBack Then

Me.gvMyGridView.DataSource=getData()

Me.gvMyGridView.DataBind()

End If

End Sub
