Hello Surya,

Thank you for writing.

If you want to use two themes at the same time you cannot use ThemeResolutionService.ApplicationThemeName, because after you set this property the ThemeName property of each control is ignored and will not affect its theme. To use two themes you have to set the theme individually to each control using the ThemeName property. One thing that will help you is using ThemeResolutionService.ApplyThemeToControlTree and passing as parameters a form and the theme name you want to set to most of the controls. After that you can set the ThemeName property for the controls you want with a different theme to the desired theme name. One draw back of this method is that you will have to set the theme in all forms separately.

I noticed that I have made an error in the forum thread you have followed by suggesting ApplicationThemeName at the bottom of the thread. Actually, I meant to write ApplyThemeToControlThree.
Now this error is addressed. 

I hope this will help. If you have further questions, I would be glad to assist.

Following this up 7 years later, it turns out that

>If you want to use two themes at the same time you cannot use ThemeResolutionService.ApplicationThemeName, because after you set this property the ThemeName property of each control is ignored and will not affect its theme.

is no longer the case. You can override the them of a control even if you have used ThemeResolutionService.ApplicationThemeName by calling:

            myControl.ElementTree.EnableApplicationThemeName = false;
            myControl.ThemeName = "Office2013Dark";

Hi Jim,

Thank you for updating the thread. Indeed the required behavior is now possible: https://docs.telerik.com/devtools/winforms/themes/using-a-default-theme-for-the-entire-application#enabledisable-the-globally-set-theme-for-a-specific-control. 

ThemeResolutionService.ApplicationThemeName = "Office2010Blue";
radGridView1.ElementTree.EnableApplicationThemeName = false;
radGridView1.ThemeName = "Office2010Silver";

Hello,
Implementing the code as below, I have faced another problem:
In objects having a child object, like RadDropdownButton or RadCheckedDropDownList,  theme of the parent object will be changed to the new theme (Office2010Silver) but dropdown-elements still remain in the main-theme (Office2010Blue).
Is there any solution to make them inherited from the parent object's theme?

ThemeResolutionService.ApplicationThemeName = "Office2010Blue";
radGridView1.ElementTree.EnableApplicationThemeName = false;
radGridView1.ThemeName = "Office2010Silver";

Hello Ali,

The popup is a separate control where you need to set the EnableApplicationThemeName property as well:

radDropDownButton1.ElementTree.EnableApplicationThemeName = false;
radDropDownButton1.ThemeName = "Office2010Silver";
var popup  = radDropDownButton1.DropDownButtonElement.DropDownMenu.ElementTree.Control as RadControl;
popup.ElementTree.EnableApplicationThemeName = false;

radCheckedDropDownList1.ElementTree.EnableApplicationThemeName = false;
radCheckedDropDownList1.ThemeName = "Office2010Silver";
var popup1 = radCheckedDropDownList1.CheckedDropDownListElement.Popup as RadControl;
popup1.ElementTree.EnableApplicationThemeName = false;

I hope this helps. Should you have any other questions, do not hesitate to ask.
