public event BeforeMouseDownEventHandler BeforeDoubleClick
Event Data
The event handler receives an argument of type BeforeMouseDownEventArgs containing data related to this event. The following BeforeMouseDownEventArgs properties provide information specific to this event.
| Property | Description |
|---|---|
| Button | Gets which mouse button was pressed. |
| Cancel | Gets or sets a value indicating whether the event should be canceled. |
| Clicks | Gets the number of times the mouse button was pressed and released. |

| X | Gets the x-coordinate of a mouse click. |

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 } }
