ExtJs GroupingView prevent sorting of the group title

How to prevent sorting of the group 开发者_运维技巧title in GroupingView. By default group titles are sorted 'ASC'. I have a situation where "Adhoc Reports" group should order last in the GroupingView.

I need the group title to be in the following order

groupName: 'Federal Reports' groupName: 'State Reports' groupName: 'Ad Hoc Reports'

This is how these are grouped in the JSON.

Try to turn on remoteSort on your store.

EDIT

Additionally try to set groupOnSort to false and remoteGroup to true.

I am not sure, honestly I could not read your post carefully, but this maybe help you. Btw, I deal an issue like that on Ext PropertGrid, and it was a headache. Disable auto sorting on property grid in ExtJS

So I set remoteGroup: true and in my server side sorted data via SQL.
