Hi together, I have a gridgroupingcontrol with an assigned data source. Now when I later add a further column to the datatable which is assigned to the data source of the grid - I get an error when I try the following: // Get the grid engine GridEngine engine = this.myGridGrouping.Engine; GridTableDescriptor parentTD = (GridTableDescriptor)engine.TableDescriptor; GridTableCellStyleInfo nameStyle = parentTD.Columns["NameOfNewColumn"].Appearance.AnyRecordFieldCell; I get the error that the "NameOfNewColumn" doesn''t exist. But the column really exists in the datasource property. I think I have to make an update to the engine or the gridgroupingcontrol so that my changes become known. How can this be done? Regards, Markus

A couple of ways you can try to handle this. If you know when you have added the extra column to your datasource, you can try calling TableDescriptor.Columns.Add and also add the column to the grid. The other thing you can try is calling TableDescriptor.Columns.LoadDefault. This should reload all the columns from teh datasource.

THIS IS BAD ADVICE:

The problem with calling TableDescriptor.Columns.LoadDefault() is that all customizations already done to the columns (such as the HeaderText value) will be wiped out when LoadDefault() runs.
