Thanks, I have emailed you a simplified version of the project with just the
combo box added.

Hi Gerhard,

>Were you able to duplicate the issue?

>Thanks.

>Have a happy day!

Yes thanks for the project. I could reproduce this issue and had worked for
several hours to get it finally working.

As to the scrolling issue, this is a known issue that if the items in
ComboBox have different width we cannot scroll

up or down properly.

Workaround is to give the VirtualizingStackPanel or StackPanel a fixed
width. I don't recommend you use

VirtualizingStackPanel currently in ComboBox because there're other known
issues regarding VirtualizingStackPanel

+ComboBox:


<ComboBox.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Width="300" />
</ItemsPanelTemplate>
</ComboBox.ItemsPanel>

To avoid potential CanLoad issue of DomainDataSource, please add the
following code to your TextBox:

<TextBox IsEnabled="{Binding
ElementName=albumDomainDataSource, Path=CanLoad}" Name="startStringTextBox"
Width="60" />

And add the following event handler for ComboBox. (I found somehow the
second binding breaks the two way binding of ComboBox so I manually "bind"
data in this event handler to work around)

private void artistComboBox_SelectionChanged(object sender,
SelectionChangedEventArgs e)
{
var album=albumDataGrid.SelectedItem as Album;
if (album != null)
{
album.ArtistId =
((Artist)artistComboBox.SelectedItem).ArtistId;
}
albumDomainDataSource.SubmitChanges();
}

<ComboBox Height="23"
ItemsSource="{Binding
ElementName=artistDomainDataSource, Path=Data}"
DisplayMemberPath="Name"
SelectionChanged="artistComboBox_SelectionChanged"
SelectedValuePath="ArtistId"
SelectedValue="{Binding
ElementName=albumDataGrid, Path=SelectedItem.ArtistId, Mode=TwoWay}"
Name="artistComboBox"
Width="120">
....

After all above steps your project works fine at my side. Please test and
let me know whether it works for you. If you have additional questions
please feel free to ask. I'll do my best to follow up.

Thanks for all your work.

The scroll part it working fine.

However, I still don't see that the binding between the two is working.
When I put 'ba' into the start string, all is working fine. When I change
the 'ba' to 'bach' and load, the combobox does not select the correct artist.

Also, if I take out the submitchanges from the code behind, the start string
and load button stay disabled. I'm not always going to want a save to be
automatic on any change in a combo box selection.

Are the development folks working to get the combo box working as expected
before they release the product?

One other question, how do I get the Load button to fire when hit enter
after putting in a start string?

Thanks again for all you work on this.
