Navigateable Properties in GridCell

[Nils]

Hi.
Small problem:
Imagine a class setup of:

public class DisplayData
{
   public string Name { get; set; }
   public SomeOtherClass Prop { get; set; }
}

public class SomeOtherClass
{
   public string OtherName { get; set; }
}

Now I have an ObservableCollection<DisplayData> to display in my Grid.
Problem is the following setup does no display SomeOtherClass nicely (how should it...)

<telerik:GridViewDataColumn
     Header="Name"
     DataMemberBinding="{Binding Path=Name, Mode=OneWay}"
     Width="2*"
     IsReadOnly="True"/>
<telerik:GridViewDataColumn
     Header="Other"
     DataMemberBinding="{Binding Path=Prop, Mode=OneWay}"
     Width="3*"
     IsReadOnly="True"/>

If I change the second column like this:

<telerik:GridViewDataColumn
     Header="Name"
     DataMemberBinding="{Binding Path=Name, Mode=OneWay}"
     Width="2*"
     IsReadOnly="True"/>
<telerik:GridViewDataColumn
     Header="Other"
     DataMemberBinding="{Binding Path=Prop.OtherName, Mode=OneWay}"
     Width="3*"
     IsReadOnly="True"/>

All displays fine. However I loose the Ability to Filter/Group the second column.
I am searching for something like:

<telerik:GridViewDataColumn
     Header="Name"
     DataMemberBinding="{Binding Path=Name, Mode=OneWay}"
     Width="2*"
     IsReadOnly="True"/>
<telerik:GridViewDataColumn
     Header="Other"
     DataMemberBinding="{Binding Path=Prop, Mode=OneWay}"
     DisplayMemberPath="OtherName"
     Width="3*"
     IsReadOnly="True"/>

And I can't seem to find any solution..

I seem to walking in the dark here.. so could someone please enlighten me ?

Yours,
Nils

Hello Nils,

According to me this code snippet is the correct way to display data:

<telerik:GridViewDataColumn
     Header="Other"
     DataMemberBinding="{Binding Path=Prop.OtherName, Mode=OneWay}"
     Width="3*"
     IsReadOnly="True"/>

About missing filtering and grouping feature, this is a known issue. The problem is that our control does not resolve data type from nested properties correctly. You can work around this by setting DataType property for the GridViewDataColumn:

DataType="sys:String"

Hope this helps.

Works like charm. Thanks.

A little OT here, but I'd prefer writing

DataType="{x:Type sys:String}"

Is there any significant difference ?

Hi Nils,

For WPF there is no difference at all. I've used this syntax because it's applicable for Silverlight too.
