In a nutshell, I have RadGrid with edit form with type of WebUserControl.
<telerik:RadAjaxPanel runat="server">
<telerik:RadGrid ...>
<Columns>
...
</Columns>
<EditFormSettings UserControlName=".../EditForm.ascx" EditFormType="WebUserControl">
</EditFormSettings>
</MasterTableView>
</telerik:RadGrid>
</telerik:RadAjaxPanel>
EditForm contains RadUpload control. The problem is: in OnUpdateCommand UploadedFiles of RadUpload all time is empty. I can't get and save uploaded file.
