ComboBox for other than enum

[roger]

I'm trying to load a collection (which is an attribute of an object) into a RadComboBox (instead of just having the id / ToString inside a textbox).

I got this working so far with a datatemplate which I apply inside the AutoGeneratingPropertyDefinition Handler.

 

DataTemplate dt = (DataTemplate)this.FindResource("TemplateComboBoxTemplate");                 
e.PropertyDefinition.EditorTemplate = dt;

The template looks like the following:
<DataTemplate x:Key="TemplateComboBoxTemplate">     
    <telerik:RadComboBox ItemsSource="{Binding Source={StaticResource TemplateComboBoxSource}, Path=Templates}"
                         Margin="0">
        <telerik:RadComboBox.ItemTemplate>
            <DataTemplate>           
                <TextBlock Text="{Binding Title}" />         
            </DataTemplate>       
        </telerik:RadComboBox.ItemTemplate>     
    </telerik:RadComboBox>   
</DataTemplate>


As I said, the above works great, except that I have no idea how to set up a two way binding 

so that the RadComboBox actually reflects the property.

Hi Roger,

You may define the DataTemplate as follows:

<DataTemplate x:Key="TemplateComboBoxTemplate">
            <telerik:RadComboBox ItemsSource="{Binding Clubs, Source={StaticResource MyViewModel}}"
                                 SelectedValue="{Binding ClubID}"
                                 SelectedValuePath="ID"
                                 DisplayMemberPath="Name"
                                 Margin="0">
            </telerik:RadComboBox>
        </DataTemplate>

On other hand, you may create directly a LookupPropertyDefinition. I am sending you a sample project illustrating both approaches.
Let me know in case you need any further assistance.

Of course, thank you!

Hi
I hope it's not too late to get a reply to this thread.
I'm getting to grips with the OpenAccess ORM, WPF Sofia Car Rental WCF Plain Services sample in OpenAccess 2012_2_816.
I've built a solution based on this sample using my OpenAccess model.
I've got a view with a RadPropertyGrid which displays an object successfully. I've also got an independent RadComboBox that displays a collection of reference data successfully. 
One of the properties in the RadPropertyGrid is a reference id to an object in the collection displayed in the combobox.
I've tried to use the LookupPropertyDefinition in the XAML, as shown in the sample you attached but I get binding errors which I'm unable to resolve.

Is there a sample like the Sofia Car Rental sample that uses LookupPropertyDefinition?

TIA 
Craig

Hi,

Hello Nagasree,

On my end the sample application provided by my colleague runs as expected. However, I prepared the same demo in WPF for your convenience.

I hope it helps.
