Trying to disable an HtmlIntputFile Control

[cesark]

Hi,

How can I disable an HtmlInputFile Control so that is not posted back when user submit the form?

I tried this:

Sub on_Button2_Click(Sender As Object, E As EventArgs)

image_path_QA.Disabled = True
...

End Sub


...

            <td><input type="file" id="image_path_QA" runat="server" size="15" /></td>

...

But it doesn’ t work, the file is posted back and the server ‘waits’ until the file added is totally uploaded. How can I ignore the control in the ‘on_Button2_Click’ subroutine?

Thanks
