I use LayoutColumns and make my records in GDBG multilined. When I add new data to underlying datatable, grid apparently fails to build the new rows in the proper order. Or at least it looks like it. Take as the example the following code. Clicking on the button few times make grid look very strange. DataSet ds; DataTable dt; DataView dv; private void Form1_Load(object sender, System.EventArgs e) { ds = new DataSet("MyDataset"); dt = new DataTable("MyTable"); dt.Columns.Add("MyCol1", typeof(int)); dt.Columns.Add("MyCol2", typeof(int)); dt.Columns.Add("MyCol3", typeof(int)); dt.Columns.Add("MyCol4", typeof(int)); ds.Tables.Add(dt); gridDataBoundGrid1.DataSource = dt; gridDataBoundGrid1.Binder.RootHierarchyLevel.LayoutColumns( new string [] { "MyCol1", "MyCol2", ".", "MyCol3", "MyCol4" }); return; } private void button1_Click(object sender, System.EventArgs e) { gridDataBoundGrid1.BeginUpdate(); gridDataBoundGrid1.Model.BeginUpdate(); DataRow nr = dt.NewRow(); nr["MyCol1"] = 1234; dt.Rows.Add(nr); gridDataBoundGrid1.Model.EndUpdate(); gridDataBoundGrid1.EndUpdate(); gridDataBoundGrid1.Refresh(); }

Hi Jeck, try setting dataBoundGrid.UseListChanged = true; Then the grid will list to ListChanged events and new records gonna be reflected. Stefan

Actually - my previous answer was wrong. I see the problem now with a sample. This is a bug in the ListChanged handler and we''ll get that corrected. For now, a workaround would be to set UseListChanged = false; But we''ll get that fixed. Stefan
