Hi Mike,

this works, thank you!

Hi Daniel, 

It looks like either the elements changes over the years, or else I made a mistake in my original code. I sed the wrong UIElement there. You have to use SplitButtonDropDownUIElement instead of SplitButtonUIElement.

public class MyDrawFilter : IUIElementDrawFilter
{
#region IUIElementDrawFilter Members
public bool DrawElement(DrawPhase drawPhase, ref UIElementDrawParams drawParams)
{
return true;
}
public DrawPhase GetPhasesToFilter(ref UIElementDrawParams drawParams)
{
if (drawParams.Element is SplitButtonDropDownUIElement)
return DrawPhase.BeforeDrawForeground;
return DrawPhase.None;
}
#endregion
}

Hi Mike,

i also need an UltraDropDownButton in our application, which can hide/show (or enable/disable) the drowdown-arrow on demand. I've tried your suggested the drawfilter-code, but it does not change the drawing-behaviour of the button, the arrow is still visible and accessable.

I'm also wondering which part of the filter does influence the arrow drawing. Or is this just a filter example and there is the code missing for hiding the arrow? Can you please give me an example then, how to hide or disable the drowdown-arrow?

Thank you and best regards,

Daniel

Yes, Boris, I'm all set.  Thanks.
