Question

I want to bind a DataTable to a BindingSource which is then bound to the GridControl. How do I add a checkedit control once the DataTable has been created?

I have a Devexpress windows application which in the designer,

1. GridControl
2. BindingSource

This GridControl‘s datasource is the bindingsource1.

I have the following in the page_Load event,

        DataTable dt = new DataTable();
        dt.Columns.Add("FirstName");
        dt.Columns.Add("Age");

        dt.Rows.Add("rambo", 60);
        dt.Rows.Add("Arnie", 35);
        bindingSource1.DataSource = dt;
        gridView1.RefreshData();

        gridView1.Columns.Add(
            new DevExpress.XtraGrid.Columns.GridColumn()
            {
                Caption = "Selected",
                ColumnEdit = new RepositoryItemCheckEdit() { },
                Visible = true,
            }
            );

Unfortunately this doesn’t seem to work. Any ideas?

Actually, I think you are very close. Try the following changes:

        DataTable dt = new DataTable();
        dt.Columns.Add("FirstName");
        dt.Columns.Add("Age");

        dt.Rows.Add("rambo", 60);
        dt.Rows.Add("Arnie", 35);
        bindingSource1.DataSource = dt;
        gridControl1.DataSource = bindingSource1;
        gridView1.RefreshData();

        gridView1.Columns.Add(
            new DevExpress.XtraGrid.Columns.GridColumn()
            {
                Caption = "Selected",
                ColumnEdit = new RepositoryItemCheckEdit() { },
                VisibleIndex = 0,
                UnboundType = DevExpress.Data.UnboundColumnType.Boolean
            }
            );

Notice that all I changed was the visible index and setting the unbound column type. Technically, I believe all you need is the visibleIndex property set to where you would like it to appear.
