C1.Win.C1FlexGrid Namespace > C1FlexGridBase Class : BeforeDoubleClick Event

Fires before the DoubleClick event is handled by the grid.

Syntax

[C1Description("Fires before the DoubleClick event is handled by the grid.")]
public event BeforeMouseDownEventHandler BeforeDoubleClick

[C1Description("Fires before the DoubleClick event is handled by the grid.")]
public:
event BeforeMouseDownEventHandler^ BeforeDoubleClick

'Declaration
 
<C1DescriptionAttribute("Fires before the DoubleClick event is handled by the grid.")>
Public Event BeforeDoubleClick As BeforeMouseDownEventHandler

'Usage
 
Dim instance As C1FlexGridBase
Dim handler As BeforeMouseDownEventHandler
 
AddHandler instance.BeforeDoubleClick, handler

Remarks

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.

Example

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, C1.Win.C1FlexGrid.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
	}
}
