    - Problem building AJAX enabled web sites after install of Visual Studio 2008 beta 2 Hi sparrez, Thanks for your update. It sounds a bit strange that a VS.NET 2005 compiled AJAX enabled website needs the 3.5.0.0 assembly. Did you try to deploy your AJAX enabled website to another machine with .NET Framework 2.0 and AJAX 1.0 Does it work there Have you tested if it worked when you deployed your AJAX website to the file system If you have any issues when trying this, please let me know. Thanks. Regards, Citizens on the earth Tag: Windows Presentation Foundation (WPF) Whetehr does the TreeView support multi-selection? Visual Studio 2008

    - Hosting ServiceLibrary(s) under IIS/WAS, how to? Thanks for the answer. Well assume that my application has ~150 services in it. Presentation tier is communicating with Bus tier through them. Presentation and Bus tiers are located on the different machines. We are thinking of using WCF for such communication. In this case all services will have identical configuration As for configuration it is clear that we can configure bindings during run-time using ServiceFactory or other ways, but what about svc files How can we correctly host our service under IIS/WAS without them Or you suggest developer create ~150 svc files and put them somewhere Tag: Windows Presentation Foundation (WPF) Whetehr does the TreeView support multi-selection?

    - Read-only attached property and authorization key Well, Since what you need is a read-only attached property, I think you'd better not to expose the ability to modify its value to outside consumers through the SetXXX method, even though this will not break anything except irritating the designer Thanks Tag: Windows Presentation Foundation (WPF) Whetehr does the TreeView support multi-selection?

    - Use of Siteminder tokens in WCF to authenticate against siteminder That's correct, if you want to send the tokens as Address Headers in the SOAP message you can't use basicHttpBinding, you could use wsHttpBinding for example. If you want to send the token as an http cookie, then you need to do grab the HttpRequestMessageProperty and add the Cookie header. (check out HttpClient in this sample for an example of how to get the HttpRequestMessageProperty http://msdn2.microsoft.com/en-us/library/aa395208.aspx ).

    - WCF - SessionId Generation I believe that is makes no real difference weither you'll use SessionId as string or as derived hash for your dictionary key ... Why Because WCF has already some code pieces which are quite slow (don't forget about network delay). So 0.1% slower or faster in this case means nothing...

    - Capturing a Click Event. Has anyone had any success with capturing a "click" event on an image created on a Canvas I see various properties for MouseUp, MouseDown, StylusUp, etc... But how about a good old-fashioned Click or DoubleClick Or must I capture and handle both mouse down and mouse up (and Mouse out to cancel the mouse down ) Tag: Windows Presentation Foundation (WPF) Whetehr does the TreeView support multi-selection?

    - Map Stored Proc XML output/input parms to EDM entities? The basic (but unfortunately unhelpful) answer is that you ought to be able to do something like you are thinking where XML is used for a hierarchy of objects both on the way into the database with sprocs and on the way out with defining queries or the like, but the truth of the matter is that this would be quite complicated, and it's not something we have samples of. Sorry. If you do put something together like this, though, we'd certainly love to hear about it. ;-) - Danny Tag: Windows Presentation Foundation (WPF) Whetehr does the TreeView support multi-selection?

    - Binding to a non-dependency property Alan, Adam, Thanks very much for taking care of my coding problem. I'm positively surprised you guys replied so quickly and detailed. I really appreciate that! It's also good to see how to construct dependency properties, but frankly speaking making each property a dependency property is quite laborious. This holds especially true when comparing former binding practices in windows forms applications with WPF. You are right in assuming that I set the binding mode to 'OneWayToSource' so that only the 'Width' property on the XAxis gets updated thus leaving the readonly property 'ActualWidth' unchanged. IMHO it's quite reasonable to assume that a set up like this should work. Perhaps I'm the only one with this opinion, but if I'm not this might be something to take into account for future WPF releases. Of course, rather than binding properties to each other, I could also subscribe to events to set the values within the handler. But I'm not sure whether this would adhere to best practice. I'm not an expert, so I don't know what's going on behind the code. I would guess that a synchronized value only holds a reference to its source thus eating up less memory than a non-synchronized value. Am I right in assuming that binding saves resources in contrast to event handling Once again, thanks for your help!

    - Select Current Row on Button Click in a Grid View Sujath and Joel, You are both correct. If your selector (ListBox, ListView, etc) contains an element that handles the mouse event, then the automatic selection will not occur. In that case, you must find the corresponding item container and set its IsSelected property. Alternatively, you can set the SelectedIndex property on the selector. There are a number of ways you can find the item container. I prefer to walk the tree of visual ancestors because it provides a more reliable solution when the bound collection contains value types. Assume you have a ListView named myListView. For your scenario, Sujath, you could add the following code to your button's Click handler: Code Snippet public void ButtonClick( object sender, RoutedEventArgs e) { ListViewItem lvi = GetAncestorByType( e.OriginalSource as DependencyObject , typeof ( ListViewItem )) as ListViewItem ; if (lvi != null ) { myListView.SelectedIndex = myListView.ItemContainerGenerator.IndexFromContainer(lvi); } } public static DependencyObject GetAncestorByType( DependencyObject element, Type type) { if (element == null ) return null ; if (element.GetType() == type) return element; return GetAncestorByType( VisualTreeHelper .GetParent(element), type); } Joel, you would do the exact same thing in the GotFocus handler of your TextBox. Notice that in the sample above I set the SelectedIndex property on the ListView. You could also just set lvi.IsSelected=true, but you may not get the desired behavior if the SelectionMode for your ListView is not Single. Another approach is to use the ItemContainerGenerator.IndexFromItem() method on the DataContext of the templated item (the Button or TextBox). Note that if the source collection contains value types and there are duplicate values in the collection, then the IndexFromItem() method is unreliable. It will always return the first instance of the specified item. Tag: Windows Presentation Foundation (WPF) Whetehr does the TreeView support multi-selection? Visual Studio 2008

    - Alternate implemenation of Skip() and Take() on DLINQ I'm worried about the scaling of paging very large result sets with DLINQ current implementation of Skip() and Take(). The internal mapping of using the ROW_COUNT() function with a large (millions of rows) result set will eat huge amounts of resources. There is much more efficient way to do paging with a two step query and SET ROWCOUNT (for an example see http://www.4guysfromrolla.com/webtech/042606-1.shtml). Has something like this been considered as an alternative implemenation of Skip() and Take() in DLINQ. Tag: Windows Presentation Foundation (WPF) Whetehr does the TreeView support multi-selection?

    - Passing graphs via SOAP Hi I'm developing a system using WCF where one of the operations returns a complex data structure. The data structure is complex in the sense that it's a graph, not a tree (in fact it's a doubly-linked list). Of course, this sort of thing is sternly rejected by the SOAP serializer. My question is, how can I work around this problem Changing the data structure appears to be out of the question. I've considered a custom serializer or using binary encoding, but I'm not sure either approach will actually lead to a workable solution.

    - How do I add a Clause to a Linq Query? Here is my problem: I want to run linq queries behind a WCF service. I want this service to inspect the type being queried, and look for a parameter called UserAccount. If it finds it, I want it to add "&& UserAccountDBID = someGuid" to the query. So far this is what I have but I get runtime errors: Code Snippet if (hasUserAccountKey) { ParameterExpression p; BinaryExpression b; MemberExpression m; p = Expression.Parameter(typeof(UserAccount), "UserAccount"); m = Expression.Property(p, typeof(UserAccount).GetProperty("DBID")); b = Expression.Equal(m, Expression.Constant(new Guid("D6323BA8-7DC4-49F2-8637-475059FA467F"))); expression = Expression.And(expression, b); } Tag: Windows Presentation Foundation (WPF) Whetehr does the TreeView support multi-selection?

    - animation for window open event Hi, I am working on a WPF application and want to add animation when a window pops open, like those when you use Window Aero theme. I use a storyboard, set the target to the window object, and begin the storyboard when window.loaded is called. However, the animation does not seem to work as well as I expect, for one thing only the content of the window (inside the default window frame, under the title bar and default close window button) is animated. The outer border, the title bar and the buttons just appear. My window has window.style set to none. I wonder if there is any way to get hold of the default window border, the title bar and the buttons to animate them. I even tried going into the control template of the window and animated from there, but the same thing happened. It seems those default features cannot be touched, except when AllowTransparency is set to true. However, setting allowtransparency to true will ensue other tricky problems. Any idea would be great.

    - Persisting a Message on the Disk / Database I think I see the problem; here is what I think is happening and a possible solution... I think the XmlReader is going out of scope, so it's Close/Dispose gets called and then later you try to GetReaderAtBodyContents which returns that original reader. I think a solution would be to buffer the message here, that is, after the assignment to originalMessage, do MessageBuffer buf = originalMessage.CreateBufferedCopy(...); originalMessage = buf.CreateMessage(); Then I think your originalMessage object will 'own' its reader and be safe to store away in a collection where you can read it later.

This technology is pretty cool and it is essentially a subset of WPF. You can begin to develop with WPF/E using the publicly available CTP: http://www.microsoft.com/downloads/details.aspx FamilyId=E63992D3-CCF5-40B9-B98A-D16BCA57467C&displaylang=en I wrote a blog post comparing XBAPs and WPF/E available here: http://cornucopia30.blogspot.com/2007/01/wpf-whats-difference-between-xbaps-and.html In addition, I have some WPF/E examples available on my blog: http://cornucopia30.blogspot.com/ If this answers your question, please select "Mark as Answer", otherwise, please post a followup question.

And are there any methods to implement multi-selection function

And I found TreeView has only SelectedItem property and hasn't SelectedItems property. But both SelectedItem and SelectedItems exist in ListView.
