parent gdbg record count

[Keith Aubin]

Hello,

This is likely a simple question, but I am stuck at the moment.

I have two GridDataBoundGrids, each with the same dataset as its datasource.

The dataset has two tables in it, MyParentTable and MyChildTable.

There is a FK relation between these tables called FK_ParentChild.

The datamembers on the GridDataBoundGrids 1 and 2 are MyParentTable and MyParentTable.FK_ParentChild, respectively.

Therefore, row selections in GDBG1 filter the rows shown in GDBG2.

My question is, from a GDBG2 event, such as Enter, how do I retrieve the number of rows shown in GDBG1? The trick is my form is created dynamically from metadata stored in a database, so I don't know beforehand how the grids are linked.

Thanks,
Keith

Hi Keith,

Sorry, please ignore the previous update.

Try using using below way in GDBG2 events to achieve your requirement as shown below.

    this.gridDataBoundGrid1.CurrentCellKeyDown += new KeyEventHandler(gridDataBoundGrid1_CurrentCellKeyDown);
void gridDataBoundGrid1_CurrentCellKeyDown(object sender, KeyEventArgs e)
        {
            Control grid2=sender as Control;
            if (e.KeyCode == Keys.Enter)
            {
                Form f = FindFormHelper.FindForm((GridDataBoundGrid)sender);
                foreach (Control con in f.Controls)
                {
                    GridDataBoundGrid grid1 = con as GridDataBoundGrid;
                    if (grid1!=null)
                    {
                        if (con!=grid2)
                        {
                            MessageBox.Show(grid1.Model.ColCount.ToString());
                        }
                    }
                }
            }
        }

Please let me know if you have any queries.
