Hi,

I am using the file upload button inside the update panel. While running the running the program first time it returns false. After that it works fine. I have added the button in post back trigger. Is there any solution for this issue. Here is the code:

        Try

            If Not myFileUpload.HasFile Then
                lblmsg.Text = "Please select the Excel file to Import"
                myFileUpload.Focus()
                Exit Sub
            End If

End sub
