We are currently using version 2015.2.826 of Telerik controls.  We are getting intermittent exceptions from one of our pages where we have codebehind for handling the grid events.  The error we are getting is:

Unable to cast object of type 'System.EventArgs' to type 'Telerik.Web.UI.GridPageChangedEventArgs'

We have searched for any other customers with this problem, but are not able to find anything.  We definitely need your help on this production problem.

Thank you,

Hi Telerik Team,

We are trying to create stand-along document, image, flash and media managers without Editor. We use RadDialogOpener to open different dialogs. It works great except we try to get select item value. We using "ClientCallbackFunction", in that function, the "args.get_value()" return an object. Can we have a method to return a html string so we can easily to display?

 script below:

function CallbackFunction( sender, args )

{

}

 Thanks,

Hello,

we have a problem with using different Assembly Versions of the Telerik.Web.Ui.dll that are deployed in the Global Assembly Cache.

We are getting the following reproducable error: 

Telerik.Web.UI.RadFormDecorator with ID='RadFormDecorator1' was unable to find an embedded skin with the name 'Metro'. Please, make sure that the skin name is spelled correctly and that you have added a reference to the Telerik.Web.UI.Skins.dll assembly in your project. If you want to use a custom skin, set EnableEmbeddedSkins=false.

The used versions are i.e: 2013.2.611.45 and 2015.1.225.45.

• Scenario1: The first page that will be opened finds the Theme correctly. If we navigate to the second page, where the other Version of the Telerik dll is used, then the error with the Theme is thrown.

• Scenario 2: If we navigate at first to the second Page (of course after a webapplication recycle), then this page works correctly and the first page throws the error.
• Scenario 3: If the two pages are using the same Version of the Telerik.Web.Ui.DLL then no error will be thrown

Do you know this behaviour and know how i can get this work?

Thanks,

Bastian John

I am trying to have a custom dropdown on the editor but for some reason it is working but its also making my nonjustify tool active upppon using it here is my code

And here is what i use in the client side event

Also I cannot get my icon to appear any ideas guys as what going on im using 30 day demo just

I have a RadWindow that contains a User Control. This user control is doing a lot of processing on load. The initial state of the RadWindow is minimized.

I want the RadWindow to NOT load the UserControl inside it when the page is initially opened. I want the user control to be loaded only when I open the RadWindow.

my function is:

function pageLoad() {
                var newTitle = $telerik.$(".rsHeader h2").text($telerik.$(".rsHeader h2").text() + " - custom title");
                newTitle.css("font-size", "small");
            }

Where we can call function Page_load(); ??

OrderLineControl and OrderWorkflowHistoryControl usercontrols contain radgrid. What I need is to utilize the available 
space on expansion. For example if the parent grid has 12 visible columns then the child grid on expansion should also occupy
12 colspan. However since we have provided the column choosing option on clientside and set Display property of each hidden
column to false, if the column is not selected to be visible, the grid is not able to set the colspan in accordance with the
visible column.

Hence to workaround the problem I am executing following peace of code on grid ItemCreated event,
(e.Item as GridNestedViewItem).NestedViewCell.Attributes["colSpan"] = {string value of number of visible columns}

The above code works fine in IE7 & IE9, however it fails in IE8 (please refer the attached images). 

Could you please help me with this.

Sachin

 

Hi,

I currently use a splitter, within one of the panels I want to embed a youtube video and importantly allow the option for full screen:

 <iframe width="560" height="315" src="https://www.youtube.com/embed/sNIMCdVOHOM" frameborder="0" allowfullscreen></iframe>

However because the way the 'RadPane' is constructed in the background it uses an iframe without the "allowfullscreen" flag here is the code telerik generates:

 <telerik:RadPane ID="ContentPane" runat="server" ContentUrl="​MainPage.aspx">

Generates

<iframe name="ContentPane" id="RAD_SPLITTER_PANE_EXT_CONTENT_ContentPane" src="MainPage.aspx" frameborder="0" scrolling="auto" style="border: 0px; height: 191px; width: 824px;"></iframe>

 If there any way I can append "allowfullscreen" onto this iframe?

Thanks

I'd like my Grid footer--where I have my grand totals to display--to move when rows within the grid are collapsed.

See screenshot for desired results.

Thanks!
