FileUpload and HtmlInputFile controls when they are used to upload files as part of an asynchronous postback are Not Compatible with UpdatePanel Controls.
Read here: UpdatePanel Control [^]

Possible alternatives:
1. Use postback trigger in case of fileupload. Since your fileupload is a part og grid, you have to either put whole grid outside update panel or have a postback trigger for it's operations

2. Replace your fileupload with new AsyncFileUpload control released as a part of Ajax XontrolToolkit lately. Look here: AsyncFileUpload Demonstration[^]

Hi ..
Use the GridView in the Update panel and use the triigger for that ... it will work...

<pre lang="xml"><asp:UpdatePanel ID="upviewalbum" runat="server">
    <Triggers>
        <asp:PostBackTrigger ControlID="btnuploadphoto" />
    </Triggers>

In the above code snippet btnuploadphoto is the button to save the image that is taken by fileupload control..thats it now you can use the gridview in the content template of updatepanel.
