GridView ButtonField Image vs Button and RowCommand

[binarymax]

I thought I would post this because it was driving me nuts. When you are firing a RowCommand from a GridView ButtonField when the ButtonField is of type Image, Page.IsPostBack is false Button column as image:

<asp:GridView ID="gvMyGrid" runat="server" AutoGenerateColumns="false" Width="200px" >
...
<asp:ButtonField CommandName="Up" ButtonType="Image" ImageUrl="Images/up.gif" />
</Columns>

When you are firing a RowCommand from a GridView ButtonField when the ButtonField is of type Button, Page.IsPostBack is true Button column as button:

<asp:GridView ID="gvMyGrid" runat="server" AutoGenerateColumns="false" Width="200px" >
...
<asp:ButtonField CommandName="Up" ButtonType="Button" Text="Up" />
</Columns>

Code Behind:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Page.IsPostBack Then
'This code will be reached on first load and also when the user clicks a Gridview ButtonField Image!!!
End If
End Sub

Protected Sub gvMyGrid_RowCommand(ByVal sender As Object, ByVal e As GridViewCommandEventArgs) Handles gvMyGrid.RowCommand
...
End Sub

It is not a question :) Its just some information that I thought would be useful since I think it is a bug with the .NET framework.
