What rid control are you using? GridControl, GridDataBoundGrid or GridGroupingControl?

There are different technique requred for each type of grid as they use different data sources.

Adding a RowLeave event handler and making a slight change in the menuhandler made the sample work ok for me.

private void menuItem2_Click(object sender, System.EventArgs e)
{
	//insert
	if(this.mouseDownRow > -1 && this.mouseDownCol > -1)
	{
		int position = this.gridDataBoundGrid1.Binder.RowIndexToPosition(mouseDownRow);
		this.gridDataBoundGrid1.BeginUpdate();
		DataRow dr = dt.NewRow();
		this.dt.Rows.InsertAt(dr, position);
		this.dt.AcceptChanges(); 
		this.gridDataBoundGrid1.EndUpdate();
	}
}

private void gridDataBoundGrid1_RowLeave(object sender, GridRowEventArgs e)
{
	dt.AcceptChanges();
}

Try this code in Row_Leave.

private void gridDataBoundGrid1_RowLeave(object sender, GridRowEventArgs e)
{
	if(this.dt.Rows.Count > 0)
		dt.AcceptChanges();
}

If I have the dataTable.AcceptChanges() in the row leave event ,then all the rows in the dataTable will have row State as Unchanged ,this is making my saving difficult.
