Remarks

The CalcHitInfo method allows you to obtain information about any element contained within the table view. This can be useful when it is required to determine which element of a view a user has clicked or which element is located under the mouse pointer. The CalcHitInfo method returns a TableViewHitInfo object that contains the required information (visual element, its location within a view, etc.).

Example

This example shows how to determine which element in a table view is located under the mouse pointer.

C#

private void grid_MouseMove(object sender, MouseEventArgs e) {
    TableViewHitInfo hi =
        ((TableView)grid.View).CalcHitInfo(e.OriginalSource as DependencyObject);
    textBlock.Text = hi.HitTest.ToString();
}

VB.NET

Private Sub gridControl1_MouseMove(ByVal sender As Object, ByVal e As MouseEventArgs)
    Dim hi As TableViewHitInfo = CType(gridControl1.View, TableView).CalcHitInfo(TryCast(e.OriginalSource, DependencyObject))
    textBlock.Text = hi.HitTest.ToString()
End Sub
