Filtering sometimes doesnt work

[Marcin]

Hi,

I have several controls in my app that uses grid. Grid is being used on all of them in the same way:

        <telerik:RadGridView x:Name="RadGridView1" ItemsSource="{Binding Items}" Margin="0"
                             RowIndicatorVisibility="Collapsed" IsReadOnly="True"
                             AutoGenerateColumns="False" CanUserFreezeColumns="False"
                             CanUserResizeColumns="True" MouseDoubleClick="RadGridView1_MouseDoubleClick" IsFilteringAllowed="True">
            <telerik:RadGridView.Columns>
                <telerik:GridViewDataColumn Header="Name" DataMemberBinding="{Binding BusinessItem.Name}" Width="*" />
...

however on some of those grids filtering and sorting is working properly, on some grids it is working only on bool columns and on some it is not working at all (I cannot see the 'tube' symbol for filtering and I cannot sort the column by clicking its header).

What may be wrong?

I have a clue. I'm binding as a ItemsSource a collection of objects of type C. C derives from B and B derives from A. What is interesting, only those columns have filtering and other features, whom underlying property is declared in class A. So in my example:

public class A {public int P1 {get;}}
public class B : A {public int P2 {get;}}
public class C : B {public int P3 {get;}}

In this case only property P1 will get filtering (via column header).

Could you please tell me the reason of such behavior?

Hello Marcin,

Could you send us a small repro project that we can debug. This will be the fastest way to resolve this issue.

Thanks in advance.

All the best,
