    If you have experienced some difficulties with the ComboBox control when using RIA Services, take a look at this general guidance for ComboBox usage posted by Jeff Handley.

    Here are a few scenarios we looked at:

    • Async loading of ItemsSource with a SelectedItem/SelectedValue binding;
    • Cascading drop-downs such as selecting Year - Make - Model for a car;
    • Binding a ComboBox to a list of non-Entity types, such as an IEnumerable<string>.

  • ComboBox Sample for RIA Services

    Kyle McClellan has posted about ComboBox and included a sample along with the post to get you started.

    I’ve seen a few good posts out there using the DomainDataSource with a ComboBox that make things look easy. Since those were already well trodden paths I thought it would be important to identify some of the harder scenarios. After a bit of investigation, three things came forward as being particularly difficult.

    • Loading ComboBox contents asynchronously
    • Implementing cascading ComboBoxes
    • Using ComboBoxes for Entity associations

    In this post John Papa explains how to bind a ComboBox to a collection of objects, and then bind a property from the selected object to some other scalar property.

    The key here are the DisplayMemberPath and SelectedValuePath properties. These apply to the object that each item in the ComboBox is bound to. In other words, these properties are set to the State, not the ObservableCollection<State>. Also, notice these properties are not data bound, they are instead set to the name of the properties respectively. We do not want the values of the properties here, we want the actual name of the properties (which is why it is called DisplayMemberPath and SelectedValuePath).

    Fons Sonnemans demonstrates a behavior that allows keyboard selection on a ListBox or ComboBox.

    Silverlight doesn't support keyboard selection on a ListBox or Combox. I have created a small Behavior which fixes this problem. You can attach the KeyboardSelectionBehavior to a ListBox or ComboBox using Microsoft Expression Blend. You drag it from the Assets and drop it on your ComboBox or ListBox. If you have a custom ItemTemplate you will have to set the SelectionMemberPath property.

    has an article on customization of the Silverlight AutoCompleteBox to be used as a type-ahead ComboBox in LOB applications.

    The AutoCompleteComboBox can be used in typical Object-to-Object associations (one that we typically encounter when creating associations in Entity Framework) as well as Foreign Key associations (the new association type introduced with Entity Framework 4).

    Jacek Ciereszko has made a simple behavior for opening ComboBox when mouse is over it.

    It might be useful in some scenario and makes one more click less for user. You can also find similar solution on site where you don’t have to click ComboBox, but only move mouse over user's profile.

    Matthias Shapiro has posted a ComboBox TextWrapping tutorial.

    Sometimes you just want stuff to work the way you want it to work. I want a property on the Silverlight ComboBox that says “WrapText”. But alas there is not one, so I have to do it myself.

    This post written by Matthias Shapiro is meant to be a center point for topics related to styling the Silverlight 3 ComboBox.

    It will go over the basic about ComboBox styling and will also get updated with links to tutorials about common design problems with the ComboBox.

  • Control Visibility with Triggers

    0 comments  /  posted by  Silverlight Show  on  Aug 11, 2009 (10 months ago)
    In this post Joel Neubeck shows two custom TargetedTriggerAction’s which allow a developer to easily tie a UIElement’s visibility to an action made on another control.

    This first trigger I very simple.  I wanted the ability to tie a checkbox to the visibility of another UIElement.  Since a checkbox derives from ToggleButton we can get creative and write a single trigger that will work with either a CheckBox, RadioButton or ToggleButton.
