Since I could have varying columns with each request, I am creating the columns for my GridView on the fly, based on the data returned from my service.  For the same reason, I am using the ValueConverter to access the data:

      for (int i = 0; i < e.Result.ResultTable.Columns.Count; i++)
            {
                GridViewDataColumn newcol = new GridViewDataColumn();
                newcol.HeaderText = e.Result.ResultTable.Columns[i].ToString();

                newcol.IsFilterable = true;
                newcol.IsGroupable = true;
                newcol.IsSortable = true;
                newcol.IsReadOnly = true;
                
                newcol.DataMemberBinding= new System.Windows.Data.Binding();
                newcol.DataMemberBinding.Converter = new IndexConverter();
                newcol.DataMemberBinding.ConverterParameter = i.ToString(); ;
                theDataGrid.Columns.Add(newcol);
            }
            
Data returns fine, column headers are correct, but I can't sort, group or filter the grid.  Clicking on a column does nothing, there is no filter indicator, and if I drag a column to the group area, I get a "You can't do that" icon.

Is this somehow related to the ValueConverter?

Thanks

Hello Patrick,

Unfortunately (and similar to MS DataGrid) RadGridView will not work fully in such scenario.

Does this mean that the Sort/Group/Filter functions will only work on a predefined set of columns?

What specifically is the limitation?

Are there any other workarounds to allow binding to a flexible dataset?

Thanks

Hi Patrick,

This limitation comes directly from Silverlight Binding class - you cannot use it with indexed properties (you cannot specify  Path).

Kind regards,

I ran into the same problem, and i'm hoping there is a workaround.  Sorting you can work around with custom sorting.  How about grouping?  If I have a dynamic value converter i also get the cannot group thing.  any ideas on make this work?  is there a custom grouping solution?

Hi,

 If you want full support for sorting, grouping, filtering, etc. you can use our DataTable

Is there a plan to correct this?

I am trying to bind to a SharePoint List/View.

Frozen Columns, Sort, Group, Filter are all requirements.

Any ideas?
