Dynamically display tooltips when mouse hover a DataGridViewCell in WinForm application

In one of my recent projects, a customer asked me to provide a dynamic tool tip depending on the DataGridViewCell that user have his mouse hovered. For a Windows Forms DataGridView, you can handle the dataGridView1.CellToolTipTextNeeded event and dynamically provide the tip text there.

dataGridView1.CellToolTipTextNeeded += new DataGridViewCellToolTipTextNeededEventHandler(data GridView1_CellToolTipTextNeeded);
void dataGridView1_CellToolTipTextNeeded(object sender, DataGridViewCellToolTipTextNeededEventArgs e)
e.ToolTipText = string.Format("tip for row {0}, col {1}", e.RowIndex, e.ColumnIndex);

Run the application, you would see a similar screen shot as below:
