GridHitInfo Class

Contains information about a specific point within a Grid View.

Namespace: DevExpress.XtraGrid.Views.Grid.ViewInfo

Assembly: DevExpress.XtraGrid.v22.2.dll

NuGet Package: DevExpress.Win.Grid


public class GridHitInfo :


GridHitInfo objects can be created by calling the desired View’s GridView.CalcHitInfo method. This method requires the test point as a parameter.

GridHitInfo class properties can be grouped into three logical categories:

  • properties identifying the View element that contains the test point. For instance, the GridHitInfo.Column and GridHitInfo.RowHandle properties identify the column and row whose elements are under the test point;
  • properties indicating whether the test point resides over a particular View element. For instance, the GridHitInfo.InColumnPanel property indicates whether the test point is over the column header panel;
  • the GridHitInfo.HitTest property identifying the type of element located under the test point.


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();
