The following properties accept/return GridHitTest values:
Remarks
GridHitTest enumeration values are returned by the GridHitInfo.HitTestproperty of a GridHitInfo object. GridHitInfo objects can be created by calling the Grid View's GridView.CalcHitInfo method.
The following images illustrate some visual elements and corresponding enumeration values. For a complete list of enumeration values, see the table below.
Examples
The following sample code shows how to identify the element located at a specific point using the GridView.CalcHitInfo method.
In the example, the CalcHitInfo method is called when you move the cursor over a Grid Control. The name of the current View element is displayed in the form's caption.
using DevExpress.XtraGrid;
using DevExpress.XtraGrid.Views.Base;
using DevExpress.XtraGrid.Views.Base.ViewInfo;
using DevExpress.XtraGrid.Views.Grid.ViewInfo;
// ...
private void gridControl1_MouseMove(object sender, MouseEventArgs e) {
GridControl grid = sender as GridControl;
if (grid == null) return;
// Get a View at the current point.
BaseView view = grid.GetViewAt(e.Location);
if (view == null) return;
// Retrieve information on the current View element.
BaseHitInfo baseHI = view.CalcHitInfo(e.Location);
GridHitInfo gridHI = baseHI as GridHitInfo;
if (gridHI != null)
Text = gridHI.HitTest.ToString();
}
