The following article describes the ActiveSections property / feature of the RadColorEditor. It gives you the ability to combine/remove different parts of the ColorEditor.
Since Q2 2012 SP, RadColorEditor provides ActiveSections property of type ActiveSectionTypes which is a flag enum with the following possible values:
The default value of ActiveSections is SaturationValuePad | HuePad | ColorModesPanel.
So How to use the ActiveSections property?
In XAML , just list your ActiveSections with comma, for example like so:
<telerik:RadColorEditor ActiveSections="HuePad, ColorModesPanel" />
In code behind you have to use the bitwise or:
this.colorEditor.ActiveSections = ActiveSectionTypes.HueSaturationPad | ActiveSectionTypes.LuminancePad | ActiveSectionTypes.ColorModesPanel;
Me.colorEditor.ActiveSections = ActiveSectionTypes.HueSaturationPad Or ActiveSectionTypes.LuminancePad Or ActiveSectionTypes.ColorModesPanel
An important note here is that you cannot use every combination of the 5 section types. The rule is: you can use one or none between [1,2] and/or one or none between[3, 4] and/or one or none of . If you use both SaturationValuePad and HueSaturationPan only the SaturationValuaPad will be visible. If you use both HuePad and LuminancePad only the HuePad will be visible.
