C#

//Get current row
CurrencyManager <code>xCM</code>= (CurrencyManager)this.dataGrid2.BindingContext[this.dataGrid2.DataSource, this.dataGrid2.DataMember];
DataRowView <code>xDRV</code>= (DataRowView)xCM.Current;
DataRow <code>currRow</code>= xDRV.Row;

System.Drawing.Point <code>point</code>= new Point(e.X, e.Y);
DataGrid.HitTestInfo <code>info</code>= this.dataGrid2.HitTest(point);
if(info.Type == DataGrid.HitTestType.Cell)
{
	// Do your thing... e.g.
        currRow[myDataTable.Columns["Date"]] = this.dateTimePicker1.Value.ToShortDateString();
}

A piece of note here. In order to be able to get the your new point from e.X and e.Y, you will have to write the code in a relevant event (such as your dataGrid's mouseUp event)

Something important: The actual change will not take part on the dataGrid itself but on the DataRow of the table that the dataGrid is bound to. By changing the column of your bound table, the value on the dataGrid's cell will automatically change

Hope this pleases the boss

Can you practice what you teach?

SuspendLayout();

... do your control moving, etc

ResumeLayout();
