Hi Vicko,
To localize GridEngineFactory, you need to pass the GridEngine object to the GroupingControl constructor in Form''''s IntializeComponet method . Here is a code snippet.
//To apply the Custom Engine to the grid...
this.gridGroupingControl1 = new GridGroupingControl( new CustomGroupingEngineFactory().CreateEngine() );
//For normal grid...
this.gridGroupingControl1 = new GridGroupingControl();
Please refer the below forum thread for more detail.
