显示DataGrid单元格的工具提示

Posted 2021-02-27

Weird issue with Intellisense and the HitTestInfo class. Just type it in, it will compile.

private void dataGrid1_MouseMove(object sender, System.Windows.Forms.MouseEventArgs e)
{
  try
  {
    DataGrid.HitTestInfo hti = dataGrid1.HitTest(e.X,e.Y);
    if(hti.Type == DataGrid.HitTestType.Cell) 
    {
      toolTip1.SetToolTip(dataGrid1, dataGrid1[hti.Row, hti.Column].ToString()); 
    }
  }
  catch{}
}
