File upload button not showing files when uploaded

Question

I have a modal popup and in the modal-body I have two asp.net controls FileUpload control and LinkButton and the markup is

<div class="modal-body">    
    <asp:FileUpload runat="server" ID="optinFileUpload"></asp:FileUpload>
    <asp:LinkButton ID="btnImport" runat="server" class="btn btn-primary btn-block" OnClick="btnImport_Click" Text="Import"></asp:LinkButton>
</div>

Then I'm uploading the button and click the Import button and code behind is

protected void btnImport_Click(object sender, EventArgs e)
{
    bool val = optinFileUpload.HasFile;
}

And the val is always showing false even if it contains the file.

Can one tell me why it is always showing false

if your file upload button will be inside update panel then it will show always false. — Shirish, Jul 15 '15 at 10:59
if its inside updatepanel it will always show false. use asyncfileupload control in ajaxtoolkit for use with update panel — Sujit.Warrier, Jul 15 '15 at 11:12
You were right it is in update panel and when I have removed it is showing the right results — Learner, Jul 15 '15 at 11:15

foreach (HttpPostedFile postedFile in FileUpload1.PostedFiles)
     {
          string fileName = Path.GetFileName(postedFile.FileName);
          postedFile.SaveAs(Server.MapPath("~/Uploads/") + fileName);
     }
