Hi,

Try this if it could help ...
Example in your code behind:

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
    Button bts = e.CommandSource as Button;
    Response.Write(bts.Parent.Parent.GetType().ToString());
    if (e.CommandName.ToLower() != "upload")
    {
        return;
    }
    FileUpload fu = bts.FindControl("FileUpload4") as FileUpload;//here
    if (fu.HasFile)
    {
        bool upload = true;
        string fleUpload = Path.GetExtension(fu.FileName.ToString());
        if (fleUpload.Trim().ToLower() == ".xlsx")
        {
            fu.SaveAs(Server.MapPath("~/UpLoadPath/" + fu.FileName.ToString()));
            string uploadedFile = (Server.MapPath("~/UpLoadPath/" + fu.FileName.ToString()));

            //Someting to do?...
        }
        else
        {
            upload = false;
            // Something to do?...
        }
        if (upload)
        {
              // somthing to do?...
        }
    }
    else
    {
        //Something to do?...
    }
}

You must have a Sub directory UpLoadPath in you apps domain rather in you
project solution to copy such file, to be visible in your apps. Otherwise this could
run in your local, but when it published you may encountered file not found error...

Hope this could help...

Hi

It should be working...
I try it...

See the entire code that I had made and run:

In Client code:

    <body>
    <form id="form1" runat="server">
    <div>
        <table width="100%">
            <tr>
                <td>
                    <asp:GridView ID="GridView1" CellPadding="4" runat="server" OnRowCommand="GridView1_RowCommand"
                        AutoGenerateColumns="false" AllowPaging="true" AllowSorting="true" PageSize="5"
                        Width="95%" OnPageIndexChanging="GridView1_PageIndexChanging" OnRowDeleting="GridView1_RowDeleting" EmptyDataText="No record in Company Table">
                        <AlternatingRowStyle BackColor="aliceBlue" />
                        <HeaderStyle HorizontalAlign="Left" />
                        <Columns>
                            <asp:TemplateField Visible="false">
