Hi, I''m using a hierarchical GDBG and adding rows programatically. When a row is added which has no children, how do I stop the plus symbol appearing next to the row by default? Cheers Chris

You can remove it by calling grid.ExpandRowAtRowIndex on your new row. DataRow dr = parentTable.NewRow(); parentTable.Rows.Add(dr); int newRowIndex = this.gridDataBoundGrid1.Model.RowCount - 1; this.gridDataBoundGrid1.ExpandAtRowIndex(newRowIndex); this.gridDataBoundGrid1.RefreshRange(GridRangeInfo.Cell(newRowIndex, 1));

I''ve got this method to work but it''s less than ideal. Every time the grid is reset, e.g. when sorted, all my rows with children are expanded. To alleviate this I will need to track the expanded state of every row, something the grid should be doing. Has this been improved in SyncFusion 3.0? I''ve read the release notes and couldn''t see anything. Thanks, Ben.

No, this behavior is the same in 3.0. The GridGroupingControl will persist expands through a sort. For a GridDataBoundGrid, as you said, you would have to handle this yourself. Here is a forum thread discussing how you can do it with a sample. http://www.syncfusion.com/Support/Forums/message.aspx?MessageID=16065
