DataGrid.HitTestInfo Class

Contains information about a part of the System.Windows.Forms.DataGrid at a specified coordinate. This class cannot be inherited.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public sealed class HitTestInfo

The DataGrid.HitTestInfo class, in conjunction with the HitTest method of the DataGrid control, is used to determine which part of a DataGrid control the user has clicked. The DataGrid.HitTestInfo class contains the row, column, and part of the grid that was clicked. See the DataGrid.HitTestType enumeration returned by the Type property for a complete list of grid parts.

To return a DataGrid.HitTestInfo, invoke the HitTest method from the MouseDown event of DataGrid control. Pass the x and y properties of the MouseEventArgs to the HitTest method.

The following example uses the HitTest method in a MouseDown event to return the DataGrid.HitTestInfo object. The row, column, and part of the grid are then printed.

private void dataGrid1_MouseDown
(object sender, System.Windows.Forms.MouseEventArgs e)
{
   Console.WriteLine();
   System.Windows.Forms.DataGrid.HitTestInfo myHitTest;
   // Use the DataGrid control's HitTest method with the x and y properties.
   myHitTest = dataGrid1.HitTest(e.X,e.Y);
   Console.WriteLine(myHitTest);
   Console.WriteLine("Column " + myHitTest.Column);
   Console.WriteLine("Row " + myHitTest.Row);
   Console.WriteLine("Type " + myHitTest.Type);
   Console.WriteLine("ToString " + myHitTest.ToString());
   Console.WriteLine("Hit " + myHitTest.Type.ToString());
}
