need to update textfield when record has been inserted/updated/deleted in GridDataBoundGrid

I''ve got a databoundgrid and a textbox right under it. every time a enter a new record/update an existing record/delete an existing record in the databoundgrid, I need to append something to the text already in the textbox. where do I put my code? *sigh* this all seems so trivial but I really can''t seem to find my way yet in .NET :(

You can handle the grid.RowEnter event.

private void gridDataBoundGrid1_RowEnter(object sender, Syncfusion.Windows.Forms.Grid.GridRowEventArgs e)
{
	//put the value in column 1 into the textbox
	string s = this.gridDataBoundGrid1[e.RowIndex, 1].Text;
	this.textBox1.Text = s;
}
