Event Data

The MouseDown event's data class is MouseEventArgs. The following properties provide information specific to this event:

Property Description
Button Gets which mouse button was pressed.
Clicks Gets the number of times the mouse button was pressed and released.
Delta Gets a signed count of the number of detents the mouse wheel has rotated, multiplied by the WHEEL_DELTA constant. A detent is one notch of the mouse wheel.
Location Gets the location of the mouse during the generating mouse event.
X Gets the x-coordinate of the mouse during the generating mouse event.
Y Gets the y-coordinate of the mouse during the generating mouse event.


If you handle the MouseDown event for a detail View, the event sender identifies the clone that has actually raised the event.

A common practice of handling the MouseDown event is to perform specific actions in response to pressing a specific View element. Refer to the Hit Information help topic for information on how to identify the element located under the mouse pointer.

using DevExpress.XtraGrid;
using DevExpress.XtraGrid.Views.Grid;
using DevExpress.XtraGrid.Views.Grid.ViewInfo;

private void gridView1_MouseDown(object sender, MouseEventArgs e) {
    GridHitInfo info = (sender as GridView).CalcHitInfo(e.Location);
    int rowHandle = info.InRow ? info.RowHandle : GridControl.InvalidRowHandle;
