Microsoft.StyleCop.Targets not found

As we are internally using StyleCop for analyzing our C# code and improving readability and code maintainability, when using the Source Code of RadControls for WPF you should have StyleCop installed on your machine.

The "Microsoft.StyleCop.Targets was not found" error states that you either do not have StyleCop installed or not completely installed on your computer.

Our source code project requires this Visual Studio add-in. You should install the latest StyleCop version and try the Source Code project once again.

Multiple Row Column Headers

I am evaluating the DataGrid you offer and I am trying to determine if it is possible to have multiple column headers on the grid. In other words the user can stack columns on top of other columns when reordering. Thank you

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

   //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()

   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;
}
