解説
This event fires before the grid processes the System.Windows.Forms.Control.DoubleClick event, and gives the program a chance to customize the behavior of the control and optionally cancel the default handling of the mouse.
使用例
The code below handles the BeforeDoubleClick event to detect double-clicks on cells in a specific column and provide a custom edit dialog instead of using the built-in editor.
void _flex_BeforeDoubleClick(object sender, BeforeMouseDownEventArgs e) { // detect double-clicks on column "Customer" HitTestInfo hti = _flex.HitTest(e.X, e.Y); if (hti.Type == HitTestTypeEnum.Cell && _flex[hti.Column].Name == "Customer") { e.Cancel = true; // cancel default handling ShowCustomEditDialog(hti.Row, hti.Column); // handle row drag/drop } }
