C# Tooltiptext, veri dizisi başlığına nasıl eklenir?

Question

 protected void PopulateReadingsGrid() 
     { 
     if (sd == null || sd.ReadingsCount == 0) return; 
     pb.Value1 = 0; 
     pb.Maximum = sd.ReadingsCount; 
     ToolTip toolTip1 = new ToolTip(); 
     DataTable dt = new DataTable(); 
     DataColumn dcIndex = new DataColumn("No"); 
     DataColumn dcDate = new DataColumn("Date"); 
     DataColumn dcTime = new DataColumn("Time"); 
     DataColumn dcUnComp = new DataColumn("UnCompensated Height"); 
     DataColumn dcCompHeight = new DataColumn(sd.isBarometric ? "Pressure" : "Compensated Height"); 
     DataColumn dcWaterDepthBelowDatum = new DataColumn("Depth of Water Below Datum"); 
     DataColumn dcTemperature = new DataColumn("Temperature"); 


     dt.Columns.Add(dcIndex); 
     dt.Columns.Add(dcDate); 
     dt.Columns.Add(dcTime); 
     dt.Columns.Add(dcUnComp); 
     dt.Columns.Add(dcCompHeight); 
     dt.Columns.Add(dcWaterDepthBelowDatum); 
     dt.Columns.Add(dcTemperature); 
     } 

Oradaki kodumun bir parçası. Sorum şu: veri ipucumun başlığı üzerine araç ipucu metni nasıl eklenir? Örneğin, araç ipucu metnini "Hayır" veya "Tarih" ... ekleyerek ...?

Answer 1

private void dt_CellMouseDown(object sender, DataGridViewCellMouseEventArgs e) 
    { 
     if (e.ColumnIndex == -1) 
     { 
      // get text 
      string msg = (sender as DataGridView).Rows[e.RowIndex].Cells[e.ColumnIndex].Value; 
      // Get mouse position relative to the grid 
      var relativeMousePosition = dt.PointToClient(Cursor.Position); 

      // Show the tooltip 
      this.toolTip1.Show(msg, dt, relativeMousePosition); 
     } 
    }
