WPF ObservableCollection CollectionView.CurrentChanged not firing.
- by EL
Hi folks,
I have a problem with one of my ICollectionViews. The ICollectionView's CurrentChanged event i not firing.
Please see my code below.
XAML:
<!-- Publication -->
<TextBlock Name="tbkPublication" Text="{x:Static abConst:Print.tbkPublicationText}" Grid.Row="0" Grid.Column="0" Margin="3" ></TextBlock>
<ComboBox Grid.Column="1" Grid.Row="0" Margin="3"
Name="cmbPublication" BorderThickness="1"
ItemsSource="{Binding Path=EnterpriseList}" DisplayMemberPath="Name"
SelectedValuePath="Value" SelectedIndex="0"
IsSynchronizedWithCurrentItem="True" />
<!-- Distribution Area Region -->
<TextBlock Name="tbkDistributionArea" Text="{x:Static abConst:Print.tbkDistributionAreaText}" Grid.Row="1" Grid.Column="0" Margin="3" ></TextBlock>
<ComboBox Grid.Column="1" Grid.Row="1" Margin="3"
Name="cmbDistributionArea" BorderThickness="1"
ItemsSource="{Binding Path=ZonesList}"
DisplayMemberPath="Name"
SelectedValuePath="Value" SelectedIndex="0"
IsSynchronizedWithCurrentItem="True" />
AND C# (ViewModel)
#region Properties
public ObservableCollection<GenericNameValuePair<int, string>> EnterpriseList
{
get { return _abEnterpriseList; }
set { _abEnterpriseList = value; }
}
public ObservableCollection<GenericNameValuePair<int, string>> ZonesList
{
get { return _abZonesList; }
set
{
_abZonesList = value;
}
}
#endregion
private void InitCollections()
{
_collectionViewEnterprise = CollectionViewSource.GetDefaultView(EnterpriseList);
_collectionViewZone = CollectionViewSource.GetDefaultView(ZonesList);
//Replace
if(_collectionViewEnterprise == null)
throw new NullReferenceException("Enterprise collectionView is null.");
if (_collectionViewZone == null)
throw new NullReferenceException("Zone collectionView is null.");
_collectionViewEnterprise.CurrentChanged += new EventHandler(OnCollectionViewEnterpriseCurrentChanged);
_collectionViewZone.CurrentChanged += new EventHandler(OnCollectionViewZoneCurrentChanged);
}
Please help. Thanks in advance.
