Can't get target of BindingOperations.SetBinding to actually fire its bindings.

Posted By:      Posted Date: August 30, 2010    Points: 0   Category :WPF
Let's say I have a user control named 'MyControl'. MyControl is used in a Window as follows: <MyControl SelectedName="{Binding Target, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" > ... </MyControl> The SelectedName property in MyControl is a dependency property that's declared as follows: public static readonly DependencyProperty SelectedNameProperty = DependencyProperty.Register("SelectedName", typeof(string), typeof(MyControl), new PropertyMetadata(string.Empty)); public string SelectedName { get { return (string)GetValue(SelectedNameProperty); } set { SetValue(SelectedNameProperty, value); } } Within MyControl is a TreeView and I want to bind the TreeView's SelectedItem's Name property to MyControl's SelectedName (we can assume that a selected item will always have a name) . To do that, I've added the following in MyControl's constructor: public CubeAssetsTreeViewControl() { InitializeComponent(); var treeViewSelectedItemBinding = new Binding("SelectedItem"); treeViewSelectedItemBinding.ElementName = "myControlTreeView"; treeViewSelectedItemBinding.Mode = BindingMode.OneWay; var treeViewSelectedItemNameBinding = new Binding("SelectedItem.Name"); treeViewSelectedItemNameBinding.ElementName = &

Wireless Web: Microsoft Mobile Internet Toolkit Lets Your Web Application Target Any Device Anywhere


If you've built Web sites using ASP.NET, you'll welcome the Microsoft Mobile Internet Toolkit (MMIT). MMIT extends the Visual Studio .NET IDE you already know by providing new controls for handheld devices letting you easily develop applications for wireless devices. This means you can write less code while adapting it to more devices. Not only does MMIT integrate with Visual Studio .NET, it extends ASP.NET as well. This article gives you the background you need to write, test, and deploy a site with MMIT and make all your code able to target specific devices for a custom fit.

Windows Forms: Developing Compelling User Controls that Target Forms in the .NET Framework


In the beginning, writing controls meant dealing with Windows messages. Then came Visual Basic controls, which introduced methods, properties, and events. Later, ActiveX controls, which ran atop COM, became popular. While each innovation in control writing brought more flexibility, nothing has matched the versatility of the new .NET Windows Forms controls and Web Forms controls. This article, the first of a two-part series, introduces the reader to Windows Forms, beginning with their inheritance from one of the .NET CLR base classes, which makes control creation much faster than before. Control programming is illustrated through the development of a login control. The equally flexible Web Forms controls will be covered in Part 2.

EventReceiver does not fire for other users than Administrator


Hi all

My code adds a EventReceiver to some SPLists. When I log into Sharepoint as Administrator, then the EventReciever is fired.

When i log in as an other user, it does nothing.


My current code is this:

string assm = "Minimizer, Version=" + FileVersionInfo.GetVersionInfo(Root.Res.DLL).FileVersion + ", Culture=neutral, PublicKeyToken=d2d19387a15c363f";
          string cls = "MinimizerPlugin.Minimizer";
          l.EventReceivers.Add(SPEventReceiverType.ItemUpdated, assm, cls);
          l.EventReceivers.Add(SPEventReceiverType.ItemAdded, assm, cls);

What can I do to register this EventReceiver to all users?

Thanks for your help!!

Target Audiences not working


Microsoft Office SharePoint Server Enterprise 2007 Version:

I created a Target Audiences for a Security Group that I created for a Pilot program that is being kicked off.  I only want the Security Group to see it.  I logged onto the site as a member OUTSIDE of the Security Group and I still saw it.  I have the example below, with the security group from Active Directory.  Any reason why it would not work?

Below is an Announcement on our Corporate Intranet site for educating users on Information Technology and computer related items.  It is a portal that we would like them to go to, to get all of their information.  I have yet to break up items based on Target Audiences, but now I think it might be a great time, as I have a way to use it that will be around for a few weeks.

jquery click event doesn't fire after postback anymore

Hello there,I have a small website where I want to display a confirmation dialog after clicking on a button.When you click the confirmButton the dialog appears. Then you can choose between Yes or No to either continue with the PostBack or to return.Problem: The first time you get into the site all works fine. But after you click Yes to continue with the PostBack, no click event will be triggered anymore.Here is some code.<asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> <script type="text/javascript"> function loadConfirmDialog() { //Dialog configurieren jQuery('#confirmDialog').dialog({ autoOpen: false, width: 400, modal: true, resizable: false }); //Dialog öffnen jQuery('#confirmButton').bind('click', function () { jQuery('#confirmDialog').dialog('open'); return false; }); //Postback ausführen jQuery('#continueButton').bind('click', function () { jQuery('#confrimDialog').dialog('destroy'); __doPostBack('confirmButton', ''); }); //Postback abbrechen jQuery('#cancel

C# target 32bit and 64bit desktops with SMO included

I have an application that uses three SQL 2008 R2 SMO assemblies.  I need to target 32 and 64 bit machines that are running either 32 or 64 bit versions of SQL 2008.  I have no idea how to handle an Any CPU build for the application.  Since the SMO assemblies are either 32 bit or 64 bit, do I have to create a 64 bit build of my app and also a 32 bit build of my app.  I have no idea how to proceed with the build at this point.  This is my first app to support 64 bit machines and servers; I have only had to work in 32 bit in the past. Also, I do not know where the best forum for this question would be.  It is not a SQL question unless the answer is in the SQL assemblies.  I am developing on 64 bit Win 7 with VS 2010 and .Net 4. The C# app is wpf. The application needs to run on 32  and 64 bit Vista machines with 32 and 64 bit SQLExpress 2008 instances, and it also needs to run on 2003 and 2008 32 and 64 bit servers running 32 and 64 bit SQL 2008 servers. Any help would be appreciated.  I expect that I don't know what I don't know on compiling apps and including assemblies in an Any CPU world. Thanks, LD

SQL Server Configuration Manager: Connection to target machine could not be made in a timely fashion

I have a SQL Server 2005 box that was moved from a domain environment to a non-domain environment and was never dropped from its original domain before moving over.  Subsequently a new domain was created at the data center this SQL Server box now resides in.  The machine was dropped from its old domain and joined to the new one.   All the while the service accounts were set to the local admin account.  When I tried to start the Configuration Manager I got the message "Connection to target machine could not be made in a timely fashion.".  I read some blog entries and tried changing all the service accounts to Local System and the error message still came up.   All of the SQL Server services run fine.  It is just this management console that I cannot open.  I wasn't with this employer when this box was moved to the data center so I do not know if it worked prior and there isn't anyone here that could give me its history.   Any help would be appreciated.

Hello,I have a base server control class for all my user controls. Inside this class I have the following declaration:#region Event Handling Management public event EventHandler ItemSaved; public event EventHandler ItemCancelled; protected virtual void OnItemSaved(EventArgs e) { if (this.ItemSaved != null) { this.ItemSaved(this, e); } } protected virtual void OnItemCancelled(EventArgs e) { if (this.ItemCancelled != null) { this.ItemCancelled(this, e); } } #endregion Concrete user controls used in the application are used always inside a ModalPopupExtender object and the popup it is always handled with server-side code.
