How to change skin on all controls on page?

[Chris Chubb]

I don't know where else to ask this, but I figured this was as good a forum as any other.

I am making a number of web user controls and each control has a property for which skin should be applied to all of the Telerik RAD AJAX controls in my web user control. Right now there are at least 15 Telerik skinnable controls on the page.

What I want to do is to write a piece of code suchly:

If (CustomSkinName <> "") Then

For Each Control In Page.Controls

If ([[Control is a Telerik Skinnable Control]]) Then

Control.EnableEmbeddedSkins = False

Control.Skin = CustomSkinName

End If

Next Control

End If

First question is: How do I determine "Control is a Telerik Skinnable Control"? 

Secondly, it would appear that Grids and Charts don't share any common ancestor that has the skinning properties. What would the proper ancestor class be? Is there a better way? Reflection?

Have you looked into using a RadSkinManager?

[Chris Chubb]

I was under the impression that the RadSkinManager could only set the skin property for built-in skins, not custom skins that I have created. Also, RadSkinManager can only have one instance per page and I am working with ascx UserControls that may have more than one of them on a page. Am I wrong in my assumptions?

Hello Chris,

Yes, RadSkinManager sets embedded skins only.

In order to check whether a control is a Telerik skinnable web control in the IF statement, you should check whether the control implements the ISkinnableControl interface. All our skinnable controls implement it, including RadGrid and RadChart.
