Styling a hosted UserControl

[superold]

Hi.

I have a UserControl which contains many Telerik controls. I host this UserControl using RadHostItem which I populate on the CellFormatting event. How do I get the RadHostItem to apply the themes to its children?

Hi Jorge Delgado-Lopez,

Thank you for writing.

You can use ThemeResolutionService class and its static ApplyThemeToControlTree method:

UserControl1 uc = new UserControl1();
ThemeResolutionService.ApplyThemeToControlTree(uc, "myThemeName");
RadHostItem hostItem = new RadHostItem(uc);
e.CellElement.Children.Add(hostItem);

I hope this helps. Let me know if you have any other questions.

Sincerely yours,

If I wanted to go about adding the theme from within the UserControl in which overridden function would I do so? I ask because it does not work when I set the theme name from within the UserControl's constructor or on the form's, which holds the usercontrol, load event. I have used:

ThemeResolutionService.LoadPackageFile()
ThemeResolutionService.LoadPackageResource()

ThemeResolutionService.ApplicationThemeName
Me.ThemeName

Hi Aaron,

I am afraid that I cannot understand very well your exact scenario and goal. Could you please open a new support ticket and send me a small sample project, which demonstrates your case? This will help me to investigate your particular scenario and provide you with accurate assistance.

Best wishes,
