GridView med fast linkbillede, der fører til et funktionskald

I gridviewets <Columns> section indføres:

<asp:TemplateField HeaderText="Test af billede">
<ItemTemplate>
<asp:ImageButton id="imagebutton1" runat="server"
    AlternateText="ImageButton 1"
    ImageAlign="left"
    ImageUrl="Excel.jpg"
    OnClick="ImageButton_Click"/>
</ItemTemplate> 
</asp:TemplateField>

I codebehind kan følgen af et klik fanges med:

Sub ImageButton_Click(ByVal sender As Object, ByVal e As ImageClickEventArgs)
Label1.Text = "You clicked the ImageButton control at the coordinates: (" & _
e.X.ToString() & ", " & e.Y.ToString() & ")"
Label1.Text = GridView1.Rows(1).Cells(1).Text
Dim row As GridViewRow = CType(sender.NamingContainer, GridViewRow)
Dim ID As Integer = GridView1.DataKeys(row.DataItemIndex).Value
Label1.Text = ID
End Sub
