How do I remove the filter three fields

Question

Good afternoon,
I own a gridGroupingControl, with two columns.
I also put the filter that comes in gridGroupingControl.
But in the filter appears by default: All, Custom ... Empty.
And then the list of column options.
Example filter column User:
(All)
(Custom. ..)
(Empty)
Alan
Roberth
Cleber
Eduardo
Diego

But I do not want these options appear in the filter:
(All)
(Custom. ..)
(Empty)

As I do I get those three filter options gridGroupingControl's column?

thank

Hi Tomio,To achieve this, you need to implement a custom filterbar cell deriving the cellmodel / cellrenderer from GridTableFilterBarCellModel / GridTableFilterBarCellRenderer. Please refer to the following Kb for more details,http://www.syncfusion.com/support/kb/666/How%20do%20I%20hide%20theSample can be obtained form the following link,http://help.syncfusion.com/samples/kb/grid.windows/GGCRemoveCustom/Custom.zipPlease let me know if this helps.Regards,Jisha
