Exception after upgrade to 2011.2.712: Item has already been added

I have a page with a SkinMaster control:

<telerik:RadSkinManager ID="RadSkinManager1" runat="server" ShowChooser="false" Skin="Sunset"</telerik:RadSkinManager>

The page was working ok in production environment for about a year. Recently, I upgraded to Telerik.Web.UI.dll 2011.2.712.40. After that I started getting exceptions of this type:

Exception type: ArgumentException

Exception message: Item has already been added. Key in dictionary: 'Telerik.Web.SkinsAssembly' Key being added: 'Telerik.Web.SkinsAssembly'

at System.Collections.Hashtable.Insert(Object key, Object nvalue, Boolean add)

at System.Collections.Specialized.NameObjectCollectionBase.BaseAdd(String name, Object value)

at Telerik.Web.SkinRegistrar.GetDefaultSkinsAssemblyName()

at Telerik.Web.SkinRegistrar.GetAllEmbeddedSkins(RadSkinManager skinManager)

at Telerik.Web.UI.RadSkinManager.FillSkins(RadComboBox chooser)

at System.Web.UI.Control.InitRecursive(Control namingContainer)

at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

The error seems to be random, it appeared twice within 10 days. So far i can't reproduce it. I get notified about the error from my web server alert service and I don't know if users get any visual indications of the error or no. I have no way of asking the users.

Any clues?

Update backgroundimage panel with javascript

Hi,

i've a page asp with a panel object. With this panel i msut update backgroundimage with javascript function.
I call the radwindow with this code:

function openRadWindowCard() {

var panel;

panel = document.getElementById('<%= Panel1.ClientID %>');

radopen("UploadImgCard.aspx?urlcard=" + panel.style.backgroundImage, "RadWindowLoadcard");

}

<telerik:RadWindow ID="RadWindowLoadcard" runat="server"

ShowContentDuringLoad="false" Width="393px"

Height="300px" Title="Caricamento immagine biglietto" Behaviors="None"

MaxHeight="300px" MaxWidth="400px" Modal="True" IconUrl="/image/iconlogo.png"

OnClientClose="RefreshBackgroud" VisibleStatusbar="False" Skin="Simple" ReloadOnShow="True">

</telerik:RadWindow>

<asp:LinkButton ID="Load_sfondo" runat="server" ForeColor="#D5842B" OnClientClick="openRadWindowCard(); return false;">Carica sfondo personalizzato</asp:LinkButton>

now when close the radwindow i must trasfer the path image to master page and refresh automatic the panel's backgroundimage.

this code is:

function RefreshBackgroud(sender, eventArgs) {

var strimage = eventArgs.get_argument();

var panel = document.getElementById('<%= Panel1.ClientID %>');

panel.style.backgroundImage = strimage;

return false;

}

and this code into radwindos is:

<script type="text/javascript">

function GetRadWindow() {

var oWindow = null;

if (window.radWindow) oWindow = window.radWindow;

else if (window.frameElement.radWindow) oWindow = window.frameElement.radWindow;

return oWindow;

}

function Close(argument) {

GetRadWindow().close(argument);

}

</script>

Protected Sub Imgbtnesci_Click(sender As Object, e As System.Web.UI.ImageClickEventArgs) Handles Imgbtnesci.Click

ScriptManager.RegisterStartupScript(Page, Me.Page.GetType(), "closeWindow", "Close('" & ViewState("DirImage") & "');", True)

End Sub

but the backgroudiamge dont update..i see with debug step to step that che variable strimage has the path correct but dont update in this code

panel.style.backgroundImage

how do you it?

bye

Telerik RadGrid, Export to Excel

I've been working with Telerik RadGrid, MasterTableView an I tried to export my data to Excel but with no success. The file is created and saved on my workstation but the file is not of "Excel" kind.

When I open the file it only contains HTML. Is this right? Excel says that the file is not of any correct Excel type!

Update: This error only occurs when you use "Excel Viewer" due to the fact that "Excel Viewer" can't convert the outputed HTML file to a "real" Excel formated document.

Is there anyway to get the output as a real Excel document not a invalid document in HTML?

Multiple issues with Export

I am using the Export facilities of the grid straight out of one of your examples and encountering several different problems. The only option that is working correctly is to export to CSV.

(1) When exporting to Excel, my Excel 2010 is opening and the data is loaded from the grid, but after a few seconds, Excel goes into a loop and I have to kill it from Task Manager.

(2) When exporting to a PDF file, the PDF file never displays but I do receive a new window filled with .net errors. (see attached screen capture.

(3) When exporting to CSV, everything works fine and the data is opened in an Excel spreadsheet which operates fine (no problem).

(4) When exporting to Word, Work 2010 starts to open then hangs (never even shows in Task Manager) and I have to click on "Cancel" on the splash screen to get out of Word.

I have included the code (both display and code-behind) below.

The version being used is 2012.3.1016.45; Windows 8 64-bit, VS2012. SQL Server 2008 R2 Standard.

Maintain Selected menu item

HI

Appologies if this has been covered, but I can't find a solution that works to my particular problem.
I have a RadMenu in a user control. This user control is in a place holder on a master page.

What I cant get to work is the menu to maintain the selected menu item when a user clicks on the menu item and the page loads.

I have enabled the EnableSelection property, but I didn't expect it to be that easy.
