Hi!

Can you please tell me how can I change the background color of dropdown list item with SetThemeValueOverride when the item is in mouseOver state?

And how can I identify the elements, primitives, properties in every case if I need to change something with SetThemeValueOverride? Is there a generic guideline?

Until now I used your Visual Style Builder, but in some specific cases it doesn't help.

e.g.: DropDownList has a ListView, but how can I access ListItems and their states (default, mouseOver, Disabled etc.) through the DropDownList element?

Thank you,
Sandor

Hello,

I am trying to style a RadDropDownButton in a winform, and am having difficulty determining where or how to edit the dropdown item list.

I've edited the shape of the RadDropDownButton by changing the ActionButton, ArrowButton and BorderElement to rounded corners, but now it looks slightly odd when the button is clicked (see pic attached).  

I would like to move the menu to be centered below the button text to the right of the rounded corners, and maybe try rounding the corners and changing the backcolor of the menu items as well.  I am not sure how to access the visual elements of the items, or dropdown menu list.

How / where can this be done?

Thanks
