Does anyone have an update on this issue? I'm running into the same
thing. Random multiple POSTs causing duplicate charges/credits for
clients. Subsequent POSTs are sent when the first POST receives a 200 0
64 response. Users swear they did not click the Submit button twice.

This bug has been forwarded to Microsoft.
This is the answer from Microsoft Bug adn reported issues:

Thanks for reporting the issue. This is a known issue and we are
investigating fixing this in the next service pack. For the time being
you could use the following work around. One obvious workaround is to
change the button type to a regular button or a link button. If you need
an ImageButton, then you can put an ImageButton in a TemplateField. You
may need to handle the Command event on the ImageButton and call
DeleteRow, passing the RowIndex as the CommandArgument, like this:

<asp:GridView ID="GridView1" runat="server">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:ImageButton runat=server id="ImageButton1" CommandName="Delete"
ImageUrl="..." CommandArgument='<%# DataBinder.Eval(Container,
"RowIndex") %>' OnCommand="ImageButton1_Command" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>

protected void ImageButton1_Command(object sender, CommandEventArgs e) {
GridView1.DeleteRow(Int32.Parse(e.CommandArgument.ToString()));
}

Thanks,

Another request for microsoft to provide an official reply. I can verify
the exact behavior describe and add the following. This occurs only in
IE (v. 6 and v. 7). Additionally it occurs on both IIS5 and IIS6, as
well as the local Cassini server.

Hello JHirsch,

Is the Gridview command issue you mentioned here means the double postback
behavior of ImageButton in GridView command field? So far, there is only an
existing issue of this. You can have a look at the following newsgroup
thread to see whether the problem you met is exact the one there:

ontrols/browse_thread/thread/a9a1bd53c27bd8b0/82c51830597e5fc8

Also, for this issue, there is already a public bug entry on the product
feedback center(also recorded in internal bug database):
