Hi Nassim,
Thanks for your interest in Syncfusion products.
There is no support for having filterbar in GridListControl as it doesn't support editing. However you can achieve this through the GDBG or GGC.
Please refer the following minimal sample which illustrates the use of GridListControl celltype in GDBG and filtered according to the relationkind reference in grid.
http://www.syncfusion.com/support/user/uploads/I52165_8b71516.zipAlso the GridFilterBar uses the DataView’s RowFilter property for filtering which need datatable to be set as datasource.
To check with the sample, change the Parentid column value and see the corresponding GridListControl cell. It will be updated according to the parentid.
Please let me know if you have any further concerns.
Regards,
Nisha
