Hi James,
To display the fixed line in a GridGroupingGrid control, you need to set the TableDescriptor.FrozenColumn property . Here is a code snippet
[c#]
this.gridGroupingControl1.TableDescriptor.FrozenColumn = "ParentName";
If you want to change the color of the fixed line than set the TableModel.Properties.FixedLinesColor property to new color. Please try the below code snippet and let me know if this helps.
[c#]
this.gridGroupingControl1.TableModel.Properties.FixedLinesColor = Color.Red;
