Hello,
sorry for digging up an old message but I have a similar problem.
I used to have a DataGrid with a nested property like that and it worked fine:
<DataGridItemsSource="{Binding SelectedItem.ApprovalPath, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" SelectedItem="{Binding SelectedPathUser}" AutoGenerateColumns="False" CanUserDeleteRows="False" Height="100" IsReadOnly="True" > <DataGrid.Columns> <DataGridTextColumnHeader="Name"Binding="{Binding Path=User.DisplayName}"Width="*"/> <DataGridTextColumnHeader="Order"Binding="{Binding Order, UpdateSourceTrigger=PropertyChanged}"Width="45"/> </DataGrid.Columns></DataGrid>
I switched to RadGridView, trying to achieve the same functionality but I got an error that it cannot find the specified property!
<telerik:RadGridViewItemsSource="{Binding SelectedItem.ApprovalPath, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" SelectedItem="{Binding SelectedPathUser}" AutoGenerateColumns="False" CanUserDeleteRows="False" Height="100" IsReadOnly="True" > <telerik:RadGridView.Columns> <telerik:GridViewDataColumnHeader="Name"DataMemberBinding="{Binding User.DisplayName}"Width="*"/> <telerik:GridViewDataColumnHeader="Order"DataMemberBinding="{Binding Order, UpdateSourceTrigger=PropertyChanged}"Width="45"/> </telerik:RadGridView.Columns></telerik:RadGridView>
While debugging I found out that it is trying to find the property "DisplayName" from the selected item object and to from the nested property of User!
Am I doing something wrong with the binding or it is a problem with bindings?
