Implementing a UI Type Editor
In some situations, a simple value-to-string conversion that allows a property to be displayed as text in the property browser might not be adequate. Also, a string-to-value configuration style may not be adequate for some types. For instance, in the case of a color property, a visual representation is more desirable. A UI type editor can provide a visual representation of a property value in a property grid control, such as a design-time property browser. A UI type editor can also provide a custom user interface for configuring the value or values of an object of a particular type.
Note An EditorAttribute is applied to a type or to a property to associate the type or the property with a UI type editor.
To implement a custom UI type editor for Windows Forms
- Define a class that derives from System.Drawing.Design.UITypeEditor.
- Override the EditValue method to set up properties of the user interface. This method is overloaded.
- Override the GetEditStyle method to inform the property browser about the editing support that you will provide.
