Prevent EnableAddNew from expanding GridDataBroundGrid beyond a specific number of rows

[Administrator]

Hello,

I'm working with a GridDataBoundGrid on a windows form, which has the "EnableAddNew" property set to true, so that the grid automatically expands 1 row at a time per the user's needs. However, I don't want the grid to expand beyond 8 rows and I'm finding the logic to be a bit tricky to prevent this. Currently I have code that looks like this:

void GridSubParts_CurrentCellEditingComplete(Object sender, EventArgs e)
{
GridDataBoundGrid grid = (GridDataBoundGrid)sender;
grid.EnableAddNew = grid.Model.RowCount <= 8 ? true : false;
}

The result is once the GridDataBoundGrid control reaches 8 rows, when you click several different cells (which clicking a given cell triggers the 'cell editing') the GridDataBoundGrid will expand to 9 rows and then shrink back to 8 rows every other click.

What is the preferred way of preventing the GridDataBoundGrid from expanding beyond a specific amount of rows? Is there a maximum rows property?

There is no maximum rows proeprty for a GridDataBoundGrid.

If your datasource is some kind of IBindingList or DataView that supports a ListChanged event, then you can use that event to set the EnableAddNew property in a timely fashion.

void _ListChanged(object sender, ListChangedEventArgs e)
        {
            IList list = sender as IList;
            if (list.Count == 8)
            {
                gridDataBoundGrid1.EnableAddNew = false;
            }
        }
