Upload with Ajax

[shahab]

Hi everyone,
I have a scenario where I insert just the filename of the file I upload in the database. For this I upload a file to the server and retrieve the filename and then save the entity. But if I  set the AjaxControlID="btnSave" I get en error saying object reference.
below is the code:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" DefaultLoadingPanelID="LoadingPanel1">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="btnSave">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="lblInfo" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>    <form id="form1" runat="server">   <asp:label id="lblInfo" runat="server"/> < asp:FileUpload ID="image" runat="server" />     <asp:Button ID="btnSave" runat="server" Text="Save"     onclick="btnSave_Click" />   </form>

and in the code behind I have the following:

private String GetUploadImageName()
    {
        if (image.PostedFile.ContentLength > 0)
        {
            //upload the file
            image.PostedFile.SaveAs(Server.MapPath("~\\Resources\\Images\\ExcerciseImages\\" +
                    txtName.Text.ToString() + ".jpg"));

            return txtName.Text.ToString() + ".jpg";
        }
        else
        {
            return "";
        }
    }

If anyone could help me point in the correct direction that be great.
Thanks
