Filter Cell content by string operations like 'StartsWith'

Hi,

My gridview is bound to collection of business objects that are generated by Linq2SQL. Some columns are bound to plain properties (string, int, etc.) while other columns are bound to entire objects like so....

                    <telerik:RadGridView.Columns>         
                           ...         
                            <telerik:GridViewDataColumn Header="ID" IsReadOnly="True" DataMemberBinding="{Binding Path=Id}"         
                                                        DataType="{x:Type System:Int32}" />         
                     
                            <telerik:GridViewComboBoxColumn Header="Items"         
                                                            DataType="{x:Type local:MyItem}"          
                                                            ItemsSource="{Binding ElementName=MyWindow, Path=ViewModel.AvailableItems}"         
                                                            DataMemberBinding="{Binding Path=SelectedItem}"         
                                                            DisplayMemberPath="ItemName"         
                                                            SelectedValueMemberPath=""/>         
                             ...         
            </telerik:RadGridView.Columns>         

Everything is working fine so far, except for the column filtering options. I want to be able to filter the 'Items' column like if it was of type string. I want to be able to choose "StartsWith" or "Contains" from the FilterEditor. All I see are equality operations to choose from. Is this somehow possible without reverting the column datatype to 'string' or having to write a custom filter editor?

Thanks,

-Stephan Ziep

CalendarButtonType.Month never received

Created DataTemplateSelector for RadCalendar.
I have done it for day, month and year:

<telerik:RadCalendar x:Name="tlrkCalendar" Grid.Row="0" Grid.ColumnSpan="2" HorizontalAlignment="Center" VerticalAlignment="Center" Visibility="Visible" DayTemplate="{x:Null}" MonthTemplate="{x:Null}" YearTemplate="{x:Null}" IsTodayHighlighted="False" SelectionMode="Extended">

the problem is that that i receive correctly CalendarButtonType.Day and Year but never CalendarButtonType.Month.
When i select year view (the view where i see all months for that year) this is the trace of what received (first column is CalendarButtonContent type) :

Year -- 01/01/2009 00:00:00

Year -- 01/02/2009 00:00:00

Year -- 01/03/2009 00:00:00

Year -- 01/04/2009 00:00:00

Year -- 01/05/2009 00:00:00

Year -- 01/06/2009 00:00:00

Year -- 01/07/2009 00:00:00

Year -- 01/08/2009 00:00:00

Year -- 01/09/2009 00:00:00

Year -- 01/10/2009 00:00:00

Year -- 01/11/2009 00:00:00

Year -- 01/12/2009 00:00:00

Custom Sorting on RadGridView

Hi,

I am unable to find OldSortingState & NewSortingState properties in GridViewSortingEventArgs.. Follwing is your example, Please suggest

private void CustomSortingGrid_Sorting( object sender, GridViewSortingEventArgs e )
{
   //Gets the value of the ItemsSource property as IEnumerable.
   IEnumerable<Employee> employees = e.DataControl.ItemsSource as IEnumerable<Employee>;
   //Checks if the value of the collection is null.
   if ( employees == null )
   {
       e.Cancel = true;
       return;
   }
   //If the sorting state is none, sort the items ascending.
   if ( e.OldSortingState == SortingState.None )
   {
       e.NewSortingState = SortingState.Ascending;
       employees = employees.OrderBy( employee => employee.GetType()
                                                          .GetProperty( e.SortPropertyName )
                                                          .GetValue( employee, null ) );
   }
   //If the sorting state is none, sort the items descending.
   else if ( e.OldSortingState == SortingState.Ascending )
   {
       e.NewSortingState = SortingState.Descending;
       employees = employees.OrderByDescending( employee => employee.GetType()
                                                                    .GetProperty( e.SortPropertyName )
                                                                    .GetValue( employee, null ) );
   }
   //If the sorting state is descending, apply default sorting to the items.
   else
   {
       e.NewSortingState = SortingState.None;
       employees = employees.OrderBy( employee => employee.EmployeeID );
   }
   //Set the sorted collection as source of the RadGridView
   e.DataControl.ItemsSource = employees.ToList();
   e.Cancel = true;
}

FooterTextAlignment

Why doesn't the FooterTextAlignment property in the following style work?

                    <Teltrik:GridViewDataColumn FooterTextAlignment="Right" FooterCellStyle="{DynamicResource FooterCellStyle}" CellStyle="{DynamicResource RightAlignedCellStyle}" Width="120" DataMemberBinding="{Binding UnaTantum,Converter={StaticResource EuroConverter}, ConverterParameter=\{0:c\}}" >          
                                <Teltrik:GridViewDataColumn.Header>          
                                    <StackPanel Margin="30,0,0,0" HorizontalAlignment="Center" Orientation="Vertical" >          
                                        <TextBlock HorizontalAlignment="Center" Text="Una Tantum"></TextBlock>          
                                    </StackPanel>          
                                </Teltrik:GridViewDataColumn.Header>          
                                <Teltrik:GridViewColumn.AggregateFunctions>          
                                    <telerikData:SumFunction ResultFormatString="{}{0:c}" SourceField="UnaTantum"></telerikData:SumFunction>          
                                </Teltrik:GridViewColumn.AggregateFunctions>          
                            </Teltrik:GridViewDataColumn>         

I tried also to set both FooterTextAlignment="Left" and FooterTextAlignment="Center" but nothing changed!!!

The style FooterCellStyle is:

                    <Style x:Key="FooterCellStyle" TargetType="{x:Type GridView:GridViewFooterCell}">          
                    <Setter Property="FontWeight" Value="Bold"></Setter>          
                </Style>
