GridTreeExpandCellRenderer()
Deault constructor.
Declaration
public GridTreeExpandCellRenderer()Properties
ExpandGlyphType
Gets or sets the type of the glyph shown in the expand cell.
Declaration
public GridTreeExpandGlyph ExpandGlyphType { get; set; }Property Value
| Type |
|---|
| GridTreeExpandGlyph |
Remarks
The default value is a triangle. You can also set a +- glyph, or a +-glyph with tree lines, or a custom drawn glyph. The property NodeColumnWidth reserves the required width of your glyph. The default value of NodeColumnWidth is 10 which is the setting used for the triangle glyph. For the +- glyph, the value of NodeColumnWidth is set to 14. If you want to explicitly provide a particular NodeColumnWidth, then you need to explicitly reset its value after you set ExpandGlyphType as setting ExpandGlypType also possibly resets NodeColumnWidth.
ExpandWidgetBrush
Gets or sets the Brush used for drawing of the primary expand glyph drawing.
Declaration
public Brush ExpandWidgetBrush { get; set; }Property Value

Remarks
When the expand glyph is the triangle, this value is set to 10. When the expand glyph is a +-, this value is set to 14. If you want to explicitly provide a particular NodeColumnWidth, then you need to explicitly reset its value after you set ExpandGlyphType as setting ExpandGlypType also possibly resets NodeColumnWidth.
