Exontrol - Grid ActiveX, NET, WPF Control - HasButtonsCustom property

Use the HasButtonsCustom property to assign custom icons to the +/- signs on the parent items. The HasButtonsCustom property has effect only if the HasButtons property is exCustom. Use the Images, ReplaceIcon methods to add new icons to the control.

The following VB sample assigns different icons for +/- buttons:
