Question

I am trying to do a similar effect to Excel when a user resizes a column in a WinForms DataGridView, where a tooltip shows the current size of the column.

Any easy way to do this?

or can you try this..

 void dataGridView1_ColumnWidthChanged(object sender,  DataGridViewColumnEventArgs e)
   {
       toolTip1.SetToolTip(dataGridView1.Columns[i].Width.ToString());
    }
