Hello Richard Thurgood,
Thank you for your interest in RadControls for Winforms.
The Quick-Start Framework's (QSF)
BubbleBar is a
demo control that demonstrate the Telerik Presentation Framework (TPF) capabilities. As it is a demo, the API of this control is not fully developped.
To change or switch off the Background you should access the background fill primitive using the following line:
this.bubbleBar1.Element.Children[0].Visibility = Telerik.WinControls.ElementVisibility.Collapsed;
You can easy change the background colors, gradient and other properties.
((FillPrimitive)this.bubbleBar1.Element.Children[0]).BackColor2 = Color.Red
...
((FillPrimitive)this.bubbleBar1.Element.Children[0]).NumberOfColors = ...
The Children[1] is BubbleBar's BorderPrimitive - it is also easy to manage by following this pattern.
To inspect and access element hierarchichy, you can use the
RadSpy tool.
Hope this helps.
Best wishes,
Peter
the Telerik team
