HitTest

Suppose I have a grid with a two level hierarchy and set a DoubleClick event handler as follows:

public void DoubleClickHandler(object sender, EventArgs e) 
{ 
  Point point = PointToClient(Cursor.Position); 
  Header header = this.HitTests.HeaderTest(point);
  // Suppose header here is a lower level header. How do I get a reference to the container Row associated with this header here? 
}

Regards,

  Hello,
  Below you will find a code for your example:

  public void DoubleClickHandler(object sender, EventArgs e)
  {
    Point point = grid.PointToClient(Cursor.Position);
    Header header = grid.HitTests.HeaderTest(point);
    Rectangle headerBounds = grid.HitTests.HeaderVisibleBoundsTest(point);
    if(header != null)
    {
      //Get a first row below the header
      Row row = grid.HitTests.RowTest(new Point(point.X, headerBounds.Bottom));
      if (row != null && row.Header == header && row.Parent != null)
      {
        foreach(Row child in row.Parent.Children)
        {
        }
      }
    }
  }

  
  Best regards,
