RadUpload and RadProgressArea loose Style

[Inge Wandsvik]

I have a RadUpload and RadProgressArea inside a DIV tag. The div tag is by default set to visible=false. I also have a RadTreeView with ContextMenus. When I click on the ContextMenu "Upload", I set the div tag visible to true. I do the upload, and everything works fine. When the progress is finished, I set the div tag visible to false again to hide the RadUpload and RadProgressArea. But, the next time I click the ContextMenu "Upload" in my RatTreeView, the RadUpload and RadProgressArea has lost the original style, and images is not displayed.

I have to mention that all the controls is inside an asp updatepanel, and the "upload button" is set as PostBackTrigger. This is my RadUpload:

<telerik:RadProgressManager ID="RadProgressManager1" Runat="server" Skin="Default2006" />
                    <telerik:RadUpload ID="RadUpload1"
                        runat="server"
                        OverwriteExistingFiles="false"
                        AllowedFileExtensions=".zip,.txt,.gif,.png,.jpg,.jpeg,.doc,.xls,.pdf"
                        initialfileinputscount="1"
                        Skin="Default2006"
                        MaxFileInputsCount="1"
                        inputsize="50"
                        width="400px"
                        MaxFileSize="1000000000"
                        ControlObjectsVisibility="None"
                        EnableFileInputSkinning="false"
                        EnableAjaxSkinRendering="true" /><br />
                    <telerik:RadProgressArea ID="RadProgressArea1"
                        BorderColor="Black"
                        BorderStyle="Solid"
                        BorderWidth="1"
                        Runat="server"
                        DisplayCancelButton="True"
                        ProgressIndicators="TotalProgressBar, TotalProgress, TotalProgressPercent, RequestSize, CurrentFileName, TimeEstimated, TransferSpeed"
                        Skin="Default2006">
                    </telerik:RadProgressArea><hr style="height:1px; color:White" />
                    <asp:Button ID="btnUpload" runat="server" Text="Last opp valgte fil" Width="278" />

Hi Inge,

The problem happens due to the skinning mechanism of RadControls for ASP.NET Ajax after an Ajax call. The problem should disappear once you set a value of true to the EnableAjaxSkinRendering property after the upload happens.
