Hi

i want to do a custom filter row as the one in the demo
http://demos.telerik.com/silverlight/#GridView/CustomFilterRow
I already included all of the codes in the demo for my project.
However, when i run it by using the radDomainDataSource to supply the itemsSource for my radgridview and it has never shown the custom filter row at all
(if i don't use the radDomainDataSource but just a static collection. Then it shows fine).

Plz help. if possible, can you test ur demo by using the radDomaindatasource to supply the ItemSsource to radgridview. 
Can you include a sample project?

thank

my codes:
A snippet of my radgridview and the codes from ur demo(i just copy EXACTLY )

the files which i have used from ur demo are(i downloaded them on 03-08-2011. So i supposed that it is the Latest demo version)
BooleanColumnHeader.xaml /cs
ColumnFilterCell.cs
ColumnFilterCellFactory.cs
CustomFilterRow.cs
DateTimeColumnHeader.xaml / cs
FilteringRow.xaml/cs
NumericColumnHeader.xaml/ cs
TextColumnHeader.xaml/ cs
FilterDescriptorValueToMaskedTextBoxValueConverter.cs


a snippet of my service code on my Server Project .web

public IQueryable<DocumentARInfo> GetUnSelectedDocumentARInfoForDepositPosting(int businessEntityId,string paymentDocumentARInfoId)
      {
          //need to check the businessEntityId = 0 in order to cancel the initial load
          //when the screen has FIRST been opened
          if (businessEntityId == 0)
          {
              return null;
  
          }
          else
          {
              int? paymentDocumentARInfoIdTOInt;
              if (paymentDocumentARInfoId == null || paymentDocumentARInfoId == "")
              {
                  paymentDocumentARInfoIdTOInt = null;
              }
              else
              {
                  paymentDocumentARInfoIdTOInt = Int32.Parse(paymentDocumentARInfoId);
              }
              var result = this.ObjectContext.DocumentARInfoes.Where(a => a.BusinessEntityId == businessEntityId && a.PostingStatusId == 2 && a.DocumentBalance != 0 && a.DocumentType.OriginalDocumentType == 1 && (a.PaymentDocumentARInfoId == paymentDocumentARInfoIdTOInt || a.PaymentDocumentARInfoId == null));
  
              return result;
          }
      }
