  1. POSL ItemsControl, command on ViewModel not firing from ItemsControl (CheckBox)
    text
    copied!<p>I'm using PRISM v2, CAL, SL4 and MVVM and have a delegate command on my ViewModel called CheckCommand. The ItemsControl contains a checkbox and I'm trying to get the items in ItemsControl/Checkbox to fire this command when it's checked - but it's not communication back to the viewmodel!</p> <p>I think it's because each items 'datacontext' is the individual object the item is bound to, rather than the ViewModel?<br> - My suspicion is actually correct, cause if I move my DelegateCommand out of the viewmodel and into the class defining the items in itemscontrol I can see the commands/methods beeing fired!</p> <p>View:</p> <pre><code>&lt;ListBox x:Name="BasketListBox" ItemsSource="{Binding BasketCollection}" MinWidth="200"&gt; &lt;ListBox.ItemTemplate&gt; &lt;DataTemplate&gt; &lt;CheckBox commands:Checked.Command="{Binding CheckCommand}" IsChecked="False" &lt;/CheckBox&gt; &lt;/DataTemplate&gt; &lt;/ListBox.ItemTemplate&gt; </code></pre> <p></p> <p>Can anyone point me in the right direction please?</p> <p>Cheers, Mcad.</p> <p>EDIT 1:</p> <p>The commanding now works, see solution below. BUT, I now run into another problem:<br> "An exception occurred while creating a region with name 'basketRegion'. The exception was: System.InvalidOperationException: ItemsControl's ItemsSource property is not empty. This control is being associated with a region, but the control is already bound to something else. If you did not explicitly set the control's ItemSource property, this exception may be caused by a change in the value of the inherited RegionManager attached property"</p> <p>Created seperate question for this problem to make it more clean:</p> <p><a href="https://stackoverflow.com/questions/4022303/prism-mvvm-itemscontrol-problem-with-view-injection">PRISM-MVVM, ItemsControl problem with View injection</a></p>
