UI for Silverlight 2010.31314

January 13, 2011

Q3 2010 SP1

New Controls:

Due to the unplanned for increase in interest in development of Silverlight line of business applications, we are making our latest addition to our Silverlight suite available before our next major release so we can enable our clients to focus on delivering their great applications without worrying about any “plumbing”. Our new Domain Data Source components ensure seamless integration between Telerik data source controls and WCF RIA Services. Now all the powerful data-shaping features of Telerik RadControls can directly translate to your domain service – filtering and sorting operations, for example, are performed directly on the server with minimum development effort. Our Domain Data Services support includes both a component that you can embed in your Silverlight page and a CollectionView Implementation that you can use in your view models for a truly MVVM-enabled scenario.
To explore the new RadDomainDataSource control in greater depth, please check its online examples and take a look at the following blog posts:




What’s New:

  • GetValueForItem() method added for GridViewExpressionColumn.
  • GetValueForItem() method added for GridViewBoundColumnBase.
  • Added: A ColumnFilterDescriptor property to GridViewFilteringEventArgs and GridViewFilteredEventArgs.

What’s Fixed:

  • Fixed: Issue where ActivateRowCommand would cause validation to fail when parameter is KeyEventArgs.
  • Fixed: If Column or Grid IsReadOnly property is set by user this value is taken into account.
  • Fixed: Tab key from an edited cell with failing validation (exception thrown in setter) causes 2 hits of the underlying property setter.
  • Fixed: An issue in GridViewHeaderCell-Part_SortIndicator is not visible in Ascending state.
  • Fixed: Adding group with null key.
  • Fixed: SortDescriptor is not removed (multi-sort scenario) when IQueryableCollectionView is used as RadGridView.ItemsSource.
  • Fixed: Null reference exception in OnDropDownPopupOpened.
  • UpdateValueEvent for numeric filter RadMaskedTextBox set to UpdateValueEvent.LostFocus.
  • Optimize FilterDescriptorCollectionExpressionBuilder so it no longer generates redundant constant expressions.

  • Fixed: Child groups are missing when grouping a column that has a Converter defined on its DataMemberBinding.
  • Fixed: Connecting lines display before first item in GroupPanel.
  • Fixed: Removing an item in a grouped scenario, when this removal causes groups to be re-arranged by the data engine, results in another item being removed.
  • Fixed: A column's filtering pop-up may appear clipped when displayed for the very first time.
  • Fixed: RadGridViewAutomationPeer GetItem() method does not work properly.
  • Fixed: BeginInsert after one BeginInsert and CancelEdit causes StackoverFlowException when item has its own Equals implementation and DataAnnotation validation fails for default values.
