Telerik Skins & Custom Skins side-by-side

Hello,

In our app, we allow users to select among default Telerik skins. We now created a custom Skin, wrapped up in a .dll, and we want that skin to be available to the users as well. So, User 1 will be using the Telerik skin Sunset, whereas User 2 will be using our Custom skin.

However, I could not find a way to register our skin dll and use it side-by-side with the default skins.

How can we implement this scenario?

Best regards.

RadWindow with a Height greater than Parent

I can't seem to find anywhere that this is explained - here is what I am looking to do:

I have a RadWindowManager on my Page
I want to call a RadWindow that may have a large grid in it
The RadWindow is set to AutoSize and if the Grid is longer than the parent browser window, I would like:
1. The RadWindow to show it's full height, without scrollbars
2. The Parent window would now scroll up and down to allow you to see the entire RadWindow content

Is this possible?

IconUrl set from Skin using incorrect path

I'm trying to set the IconUrl for a RadWindow from a .skin file, thusly:

<telerik:RadWindow runat="server" SkinID="AddPersonNoteWindow"

IconUrl="Images/Icons/note_add.png" />

The value is applying, however it's coming out incorrect:

background-image: url("//App_Themes/Default/Images/Icons/note_add.png")

The double forward slashes near the beginning cause the icon to not work.

What's up with this?

[EDIT]

Seems unrelated to the Skin file. When I set the icon without the skin file, I get the same issue.

I think the Telerik code should probably not generate these double slashes.

How do I use Ribbonbar Togglebuttons clientside?

Hi,
I want to be able to prevent the toggle button from posting back, while retaining the toggle state change in order to run some custom client-side code that represents the action taken by the button-click.

I noticed that one can cancel the postback by using:

args.set_cancel(true)

however when this is done, the toggle event itself is completely cancelled and the state remains as-is. There doesn't seem to be any Postback="false" options on the RibbonBar items, am I missing something?

Thanks,

RibbonBar

WindowManager UpdatePanel issue

Hi guys,

I’m having a issue with a RadWindow which contains an UpdatePanel in combination with the RadWindowManager.

When the popup is added during a GET request it throws an error:

Cannot unregister UpdatePanel with ID 'test' since it was not registered with the ScriptManager. This might occur if the UpdatePanel was removed from the control tree and later added again, which is not supported.

When I disable the line: “createRadWindow()” it works and the popup is visible.

Why can’t the popup be created during a GET request?

I’ve read this page: http://www.telerik.com/support/kb/aspnet-ajax/window/cannot-unregister-updatepanel-with-id-updatepanelid-since-it-was-not-registered-with-the-scriptmanager.aspx

But I use the RadWindowManager because it recreates the RadWindow from the ViewState in a postback request.

In short I have two questions:
How can I fix this issue? I Need the RadWindowManager to recreate my windows so events for controls on these dialogs work properly.
Why does the popup work when created from a postback and not from a get request.

Kind regards,
DvdBrink
