Bind to WCF Ria Service at Runtime

[Pim Kerkhof]

Hello,
I want to create a combobox control at runtime and bind it to a DomainDataSource.
The control is visible and items are visible, but the selected item is not set.
What am i doing wrong here?

 

 

Binding binding2 = new Binding();

 

 

 

PropertyPath path2 = new PropertyPath("sFieldName");

 

binding2.Path = path2;

binding2.NotifyOnValidationError =

 

true;

 

binding2.ValidatesOnExceptions =

 

true;

 

binding2.TargetNullValue =

 

"";

 

binding2.Mode =

 

BindingMode.TwoWay;

 

binding2.Source = DomainDataSourceName;

combobox.SelectedValuePath =

 

"Tag";

 

With regards,
Pim

Hello Pim,

I would suggest you to set SelectedValue of RadComboBox. Attached you can find the project I made for you. 
For more information, please refer to the following link - http://www.telerik.com/help/silverlight/radcombobox-features-selection.html

I hope this helps!

All the best,

Hello George,

When I put the ComboBox in XAML together with  DomainDataSource.DomainContext it is all working great!
When I leave the DomainDataSource.DomainContext in XAML and generate the Combobox in code behind (in page_loaded) is does not bind for some reason.
Do I need to use the MVVM pattern to get it working?

Hello Pim,

Yes, I would suggest you to use MVVM pattern in order to accomplish it, or set it in the constructor, after InitializeComponent(), not in the Loaded event handler.
