Easiest way to bound data from DB table with population to combobox is to put DomainDataSource into dataform here is sample (SL 4) i write only what need to put in datafield an ria must be NOT in datafield, just make sure you pit it inside dataform. No need aditional coding in C# <toolkit:DataField Label="Customer"> <ComboBox Height="23" ItemsSource="{Binding ElementName=customersTabDomainDataSource, Path=Data}" Name="customersTabComboBox" Width="120" DisplayMemberPath="ShortOrgName"> <ComboBox.ItemsPanel> <ItemsPanelTemplate> <VirtualizingStackPanel /> ItemsPanelTemplate> ComboBox.ItemsPanel> ComboBox> toolkit:DataField> <riaControls:DomainDataSource AutoLoad="True" d:DesignData="{d:DesignInstance my:CustomersTab, CreateList=true}" Height="0" LoadedData="customersTabDomainDataSource_LoadedData" x:Name="customersTabDomainDataSource" QueryName="GetCustomersTabsQuery" Width="0"> <riaControls:DomainDataSource.DomainContext> <my:CustomersDomainContext /> riaControls:DomainDataSource.DomainContext> riaControls:DomainDataSource>

Any updates on this regarding source_code?
I find it really hard to just make to simple comboboxes dependant on each other in a dataform..

Hi Louis

I suspect that I may have been premature - adding a combobox continues to be a nightmare, even in my own project. Please let me have a couple of days and I'll post a fuller response.

Regards

Scott

Very clean explication. I just try it and it's working very well (outside my DataForm). But If I put my combobox inside my DataForm it's not working :

What's can I do for that?
THank you a lot Scott again

@Claudio; good question. I haven't posted any source but it seems as if it would be helpful to do so. I'll try to do this, this weekend.

@Orion; no probs. I came from the Windows Foms world and pretty much bypassed ASP.NET, however I understand where you're coming from. There's tons of fantastic stuff in the RIA Services / Silverlight world (if only I was a creative designer!!) but then a small set of what-you-would-think-would-be-basic-stuff, such as comboboxes, are just a nightmare.

Thanks for reading, and 3 x thanks for responding

Scott,
Thanks for writing this up – I'm toying with a Silverlight/RIA Services app and coming from the world of ASP.NET I'm having to learn a lot of things new again.

Hi Scott,
Where do you keep the source code for the articles?
Have you got the source code for the "Silverlight 4 and data-bound combobox – the answer" article?
Cheers
