Binding to a different collection

[Wellpartner]

I'm converting from 2011.3.1116.35 to 2017-3-913.40.  This works in the old version but not in the new version.

My RadGridView is bound to an ObservableCollection named DrugList, however the ComboBoxColumn is bound to a different ObservableCollection named BrandGenericCodeList.  I'm trying to do the binding in XAML:

<UserControl x:Class="MyApp.ucDrug"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:telerikData="clr-namespace:Telerik.Windows.Data;assembly=Telerik.Windows.Data" 
             xmlns:telerikGrid="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.GridView"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
...
                <telerikGrid:RadGridView x:Name="radGridView"
                                         Grid.Row="1"
                                         AutoGenerateColumns="False"
                                         CanUserDeleteRows="True"
                                         IsSynchronizedWithCurrentItem="True"
                                         ItemsSource="{Binding DrugList}"
                                         ShowColumnFooters="True"
                                         Deleting="radGridView_Deleting"
                                         RowValidating="radGridView_RowValidating"
                                         SelectionChanged="radGridView_SelectionChanged">
                    <telerikGrid:RadGridView.Columns>
                        <telerikGrid:GridViewDataColumn Header="Name" DataMemberBinding="{Binding DrugName}" />
                        <telerikGrid:GridViewComboBoxColumn Header="Brand/Generic"
                                                            DataMemberBinding="{Binding BrandGenericCode}"
                                                            DisplayMemberPath="Value"
                                                            IsLightweightModeEnabled="True"
                                                            ItemsSource="{Binding BrandGenericCodeList}"
                                                            SelectedValueMemberPath="Name"
                                                            UniqueName="BGC" />

 

Any help is appreciated.  Thank you.

I was able to do this in code:
((GridViewComboBoxColumn)this.radGridView.Columns["BGC"]).ItemsSource = BrandGenericCodeList;

... but am wondering if it's possible to do this in XAML?

Hello Wellpartner,

Could you please clarify whether the DrugList and BrandGenericCode properties belong to the same class and are both public properties? If that is not the case, you may need to explicitly set a Source or RelativeSource for the binding. Here's an example:

ItemsSource="{Binding DataContext.BrandGenericCodeList, RelativeSource={RelativeSource AncestorType=telerik:RadGridView}}"

For your convenience, I've also prepared a small sample project which demonstrates a similar setup where the column is bound as expected.

Please let me know if you find this helpful.
