I experienced the same problem. With a grouping collection you can get around it by setting a filter on the collection that is the source for the groupingcollection and calling refresh() on the groupingcollection every time it should reflect a change. Refresh updates the view as well.
I did not find a way to do it with XML short of reassigning the dataProvider. In both cases you have to track the open items and re-open them after the refresh or reassignment. I have no idea if this is the 'right' way to do it, but it works at least ... it would be nice if one could apply a filter at the column level that would reduce the number of rows shown. ...paul On 10/3/07, letterpigeon <[EMAIL PROTECTED]> wrote: > > Hi, > > With the normal DataGrid object, we can perform filtering by doing > > grid.dataProvider = someArrayColection > grid.dataProvider.filterFunction = myFilterFunction. > > However, with the advanceddatagrid, if the do, > grid.dataProvider = someHierarchialData > > afer this statement, the grid.dataProvider variable will still be > null, because internally in the setter of dataProvider, > grid.dataProvider is never set of someHierarchialData is of type > IHierarchialData, and therefore, I can't proceed with specifying the > filter function. > > How is filtering supposed to be done for AdvancedDataGrid? > > Just a little more background on what I'm doing.
