  WCF RIA Services cannot find FilterDescriptor

  Jan 11, 2010 09:06 PM | LINK

  Hi,

  does anyone ever encounter this problem before?

  Error 1 The property 'FilterDescriptors' does not exist on the type 'StackPanel' in the XML namespace 'clr-namespace:System.Windows.Controls;assembly=System.Windows.Ria.Controls'. C:\Users\Silverlight3\Desktop\REVDemocode\WCFRIAServices\HRApp\HRApp\Views\EmployeeList.xaml 35 18 HRApp
  

   

  my reference in XAML is:

  xmlns:riaControls="clr-namespace:System.Windows.Controls;assembly=System.Windows.Ria.Controls"

   

  this reference works well with the SortDescriptor before....

   

  Thanks,

  raccoon

  i think you must try to set FilterDescriptor in code behind first !

  hi.. but I already have it under the databinding part in XAML, as attach code below, so I dont think I need the code behind. Below are some of the codes regarding filterdescriptor that I highlight, and on the lower area there is datagrid binding.. any idea why it generates the error that I mention.

   

         <StackPanel Orientation="Horizontal"                   HorizontalAlignment="Right"                   Margin="0,-16,0,0">         <TextBlock VerticalAlignment="Center"                     Text="Min Vacation Hours Filter" />         <TextBox x:Name="vacationHoursText" Width="75"                   FontSize="11" Margin="4" Text="0"/>      </StackPanel>      <riaControls:DomainDataSource             x:Name="employeeDataSource"             LoadSize="20"             QueryName="GetSalariedEmployees"             AutoLoad="True">        <riaControls:DomainDataSource.DomainContext>          <ds:OrganizationContext/>         </riaControls:DomainDataSource.DomainContext>        <riaControls:DomainDataSource.SortDescriptors>          <riaData:SortDescriptor PropertyPath="VacationHours"                                   Direction="Ascending" />        </riaControls:DomainDataSource.SortDescriptors>        <riaControls:DomainDataSource.FilterDescriptors>         <riaData:FilterDescriptorCollection>           <riaData:FilterDescriptor                  PropertyPath="VacationHours"                  Operator="IsGreaterThanOrEqualTo">             <riaControls:ControlParameter                  ControlName="vacationHoursText"                  PropertyName="Text"                  RefreshEventName="TextChanged" />           </riaData:FilterDescriptor>          </riaData:FilterDescriptorCollection>       </riaControls:DomainDataSource.FilterDescriptors>       </riaControls:DomainDataSource>       <data:DataGrid MinHeight="100"                IsReadOnly="True"                ItemsSource="{Binding Data, ElementName=employeeDataSource}"               x:Name="dataGrid1" />  </StackPanel>
