Hello Tony!

I can find any way to have correct sorting of grouping data. I need to group data which has 'select' format. After the grouping the data from the groupText (I mean group header row) will be displayed unformatted. You can see the problem on the demo. I group here by the column 'subSource'. One can see that the data are displayed unformatted also here. It is the same grid, but with formatted date, grouped also by 'datetime'. So we have two problems 1) the data from the group header row will be displayed unformated 2) the sorting of data grouping column will be done as sorting of this unformated text information.

By the way index defined as function of sorttype defined as function on the grouping column will be not called. They will be used only if one click on the header of the corresponding column, but not during grouping sorting.

One more problem. If one define groupDataSorted: true parameter of groupingView then data will be displayed at the first time unsorted (because it is the feature for remote data), but after the click on the header of a column the grouping will be sorted as a strings. So the setting can not be used for the local data – only for remote data where the sorting do the server.

In the current grouping limitation I could not find anything about usage only string or number types.

Could you modify the code th display the data in groupText formated in the same way as the data in the grid?

Thank you
Oleg
