I have FileUpload control in EP user control as shown below.
<dynamics:AxSection ID="FileUploadSection" runat="server" Caption="<%$ AxLabel:@SYS93173 %>">
<dynamics:AxGroup ID="FileUploadGroup" runat="server">
<Fields>
<asp:TemplateField ><InsertItemTemplate>
<asp:FileUpload ID="uploadDoc" runat="server" /> <asp:Button runat="server" ID="btnFileUpload" Text="Upload" OnClick="btnFileUpload_Click"/></InsertItemTemplate>
</asp:TemplateField>
</Fields>
</dynamics:AxGroup>
</dynamics:AxSection>
when in codebehind file i try to find the control , it returns null.
FileUpload fileuploadctrl = (FileUpload)this.FileUploadSection.FindControl("uploadDoc");
here fileuploadctrl returns as null. what's the reason ? why control is not being captured using FindControl method here?
Please guide. Thanks.

Got it. You need to Find control using FindControl Method if you have single file control on page.
You can write below code
if (Request.Files == null || Request.Files.Count == 0 || Request.Files[0].FileName == string.Empty)
{
// File is not selected from file upload control
}
else
{
// file is selected from file upload control
}
