[CLOSED] Dynamic GridPanel with Grouping Summary and Sorting
Hi,
I have a page which contains a GridPanel which is loaded dynamically and has a GroupingSummary plugin attached.
Does anyone know if it is possible to set the order of data within each group whilst having the grouping columns ordered in descending order?
I am binding data to the store using "</FONTstrData.SetDataFromJson" and the data passed from to this function is ordered correctly (date descending and then username ascending). However, the date field is not ordered in descending order (see Image1). If I add
[CODE]
strData.SortInfo.Field = "DateValue";
strData.SortInfo.Direction = Ext.Net.SortDirection.DESC;
strData.RemoteSort = true;
[CODE]
to the store then the dates are ordered in descending order but the child data is not ordered by the UserName field (see Image2)
Any suggestions would be greatly appreciated!
Thanks
