[Solved] "Reduce XAP size..." option disables Right Click Context Menu and Spell Checker

[Don]

Why is it that when I check the "Reduce XAP size by using application library caching" option on a Silverlight 4 project, right-click Context Menus and Spell Checker inside the RadRichTextBox no longer work? To elaborate further, I've referenced Telerik.Windows.Documents.Proofing.Dictionaries.En-US.dll and when "Reduce XAP size by using application library caching" option is unchecked the dictionary is working. However, when I check that option, all words get underlined in red.

Is there a way to make this to work? Probably code behind or some workaround? In order to replicate ths problem do the following:
1. Create a VS2010 Silverlight 4.0 Navigation Project (Out-of-the-box).
2. Add a Telerik RichTextBox to the Home.xaml
3. When the Telerik dialog comes up select Word Processor and check all options except read-only.
4. Build and Run the project to see that it works.
5. Test the the "Reduce XAP size by using application library caching" option by checking the options and building and running it again.

P.S. We need to use the application library caching option because Telerik's libraries at this time are about 3MB and would probably grow larger when we use more of Telerik's libraries. This would cause performance issues if we download it always together with the XAP file.

Thanks,

Hi Don,

All additional UI components and dictionaries are normally instantiated by MEF. If application library caching is turned on, when MEF tries to find types they are in the assemblies still on the server, thus they cannot be loaded.
As a workaround you can manually instantiate them and  set the following properties:

// Next method calls are required only to work around limitations for using MEF
this.editor.FindReplaceDialog = newFindReplaceDialog();
this.editor.ParagraphPropertiesDialog = newRadParagraphPropertiesDialog();
this.editor.FontPropertiesDialog = newFontPropertiesDialog();

this.editor.InsertSymbolWindow = newRadInsertSymbolDialog();
this.editor.InsertHyperlinkDialog = newRadInsertHyperlinkDialog();
this.editor.ManageBookmarksDialog = newManageBookmarksDialog();

this.editor.ContextMenu = newContextMenu();
this.editor.SelectionMiniToolBar = newSelectionMiniToolBar();
this.editor.ImageMiniToolBar = newImageMiniToolBar();

this.editor.InsertTableDialog = newInsertTableDialog();
this.editor.TablePropertiesDialog = newTablePropertiesDialog();
this.editor.TableBordersDialog = newTableBordersDialog();

this.editor.SpellCheckingDialog = newSpellCheckingDialog();
this.editor.EditCustomDictionaryDialog = newEditCustomDictionaryDialog();

this.editor.ImageEditorDialog = newImageEditorDialog();
this.editor.FloatingBlockPropertiesDialog = newFloatingBlockPropertiesDialog();

this.editor.InsertDateTimeDialog = newInsertDateTimeDialog();

((DocumentSpellChecker)this.editor.SpellChecker).AddDictionary(newRadEn_USDictionary(), CultureInfo.InvariantCulture);

somewhere after InitizializeComponents in your constructor.
You can also check out Telerik Minifier to minimize the size of the assemblies you use and the size of the XAP. More information on it can be found in our online documentation.

Best wishes,

Thanks for the answer and the additional information on the minifier which helped a lot.
