WPF ComboBox Loaded Event - Handling Globally

Posted By:      Posted Date: August 27, 2010    Points: 0   Category :WPF
Hello, I am having trouble hooking up to a WPF ComboBox Loaded event when trying to do it globally with EventManager.RegisterClassHandler in the parent control rather than with XAML right on the control.  Here is the code for the ComboBox control: <DataTemplate x:Key="MyUIEditor"> <ComboBox Width='Auto' x:Name="Combo" ItemsSource="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type local:MyControlWPG}}, Path=MyCollection}" SelectedValue="{Binding Value}" DisplayMemberPath="Name" SelectedValuePath="FullName" Background="Transparent" /> </DataTemplate>   Here is the code for the global event handler:   public partial class MyControlWPG : UserControl public MyControlWPG() { InitializeComponent(); EventManager.RegisterClassHandler(typeof(ComboBox), ComboBox.LoadedEvent, new RoutedEventHandler(Combo_Loaded)); } The event handler gets hit when I declare Loaded = "Combo_Loaded" in the XAML right on the ComboBox control but not when I use the global handler.  Any ideas as to why it doesn't get hit when doing it this way?

Exception thrown when handling Window.Loaded event


Why is the exception assistant not "fired" in a debugging session when a Window.Loaded eventhandler calls code which throws an exception ?
        private void Window_Loaded(object sender, RoutedEventArgs e)
            //Application.Current.DispatcherUnhandledException +=
               new System.Windows.Threading.DispatcherUnhandledExceptionEventHandler(Current_DispatcherUnhandledException);
            int a = 1;
            int b = 0;
            int c = a / b;

        void Current_DispatcherUnhandledException(object sender, System.Windows.Threading.DispatcherUnhandledExceptionEventArgs e)

Removing the comment signs (//) thus presenting an UnhandledException handler devinately makes the assistant "firing".

TextBox AutoPostBack not working when handling other DHTML event


I have to format a number in a TextBox while it is being typed. Right after the TextBox looses focus, I need to do other processing on server side, including some database queries.

I'm doing the formatting by handling the onkeyup event, client side. But when I add the handler, the onTextChanged event stops firing on the server. I've tried different return values for the handler but unfortunatelly I'm stuck.

To reproduce the problem, here is a sample where the formatting function was replaced by a simple "convert to uppercase" function. You'll see that, contrary to the expected, the Label doesn't get filled when the TextBox looses focus. It does get filled, however, if the user presses the ENTER key.

What can I possibly be doing wrong with such a simple task?

How to determine if a loaded event is fired as a result of a navigation button?


I want to perform different actions in my page loaded event based on whether or not the page is being loaded as a result of a navigation button click (ie if the navigation GUI back/forward button was pressed then I want to do A else do B).

Is there a built in flag that I can reference?

Dynamically Loaded UserControl, receiving the click event from UserControl to Parent Page



   In a page , when I click a button 'showDialog' I am loading the user control dynamically in a dialog.  I am linking to the event in the user control as explained below. The parent page is not receiving this event.

  ex: (This is in the page class)


         UseControl1 gc = dlg.LoadContent(:\UserControl1.csx);

        gc.CausePostback += new EventHandler(execute_CausePostback());



   // I am trying to update the details grid in parent page


In UserControl class after clicking the submit button


  raise event CausePostBack();


Any help is appreciated.



System.ComponentModel.PropertyChangedEventHandler not handling the event



I'm working in a wpf app that is binding controls to a class that implements INotifyPropertyChanged. I'm trying to track when there are changes to the underlying object by setting a flag whenever a property is changed. To do so, I wired up an event handler to the PropertyChanged event of the class like so:

_facilityLogic.PropertyChanged += new System.ComponentModel.PropertyChangedEventHandler(facilityLogic_PropertyChanged);


public void facilityLogic_PropertyChanged(object sender, System.ComponentModel.PropertyChangedEventArgs e)
Can anyone tell me why this event handler never gets called? The event is firing, but SetIsChanged() never gets called.

Need help on Data binding with DPs and Control Loaded event



I have a very interesting issue and i have been breaking my head on it since a long time.

I am new to WPF and related things like MVVM and all.

I have a window in which i place a user control which hosts a TabControl inside it.

This tab control has Custom Radio Button and Combo boxes which expose few Dependency Properties, Now while these custom controls are loaded author checks for the values and does 'something particular' which is intended behavior. However in my case while the control is being loaded the DPs have null values. I see the DP property changed events being fired post Load of that control only in my case. It works okay on other windows.

This is kind of strange to me as I would expect that the DPs would be bound to related values before the control gets loaded, but i dont see that behaviour here.

 I have read on MSDN that the DPs should be set properly before load event, and in a sample application i see it behaving as per MSDN.

Binding is happening properly as there are no errors in out put window + I get the DP - Property changed events as well, but this happens only after load (I dont know why??)

Any help would really be appreaciated.



Handling button clickevent in Usercontrol that is being loaded dynamically


Hi I need some ideas to do this:-

I have ASPX page named  ArtifactReporting.aspx where I have 3 linkbuttons. For each button I have 3 different UserControls to be loaded dynamically. So I have written for each click

UserControl uc = (UserControl)this.LoadControl("<ASCX page name>");

Now in one of the ASCX page I have a server side button. When I click on the button, the content of the ascx is going off, which is correct, because the page post back is happening and in Page_Load I have not written anything that will load the ASCX page.

Can anybody give me an idea on how to go about this? I need if I load an usercontrol dynamically, I should be let the users carryout operation that usercontrol.

Handling the Same Event In More Than One Client


Is it possible to handle the same event in more than one client without using Remoting or WCF?  In my test example I have 2 console apps and a class library all in the same solution.  The event lives in a Singleton class in the class library and both console apps have a reference to the dll and have handlers for the event.  I have the 2 console apps set as multiple startup projects; however the event appears to only be firing to the one that is "active".  If I could get confirmation on whether what I'm trying is not possible (or whether I'm going about it the wrong way) it would be much appreciated.



Hand Gesture Recognition and Event Handling in WPF using Kinect



I have created an application which uses OpenCV API for Hand Gesture Recognition.It recognizes the hand movement and the event is handled as per hand gestures.I wish to know whether it is feasible for Kinect Sensor to act as an alternative for Hand Gesture Recognition in my project.Please note that my application is a windows desktop application which runs on WPF using C#.net.

There is no relation between my application with Xbox.I wish to know whether kinect is applicable only for Xbox apps/games or it can be applied to normal windows applications which uses windows forms or WPF?




Every self-respected programmer should include exception handling techniques. Sometimes your application will generate an error. Regardless of who was responsible for this error, the programmer or the user, it is up to the first to include the necessary exception handling techniques to keep his/her program from crashing. The .Net environment provides useful techniques for avoiding disastrous errors such as try-catch statements and user-defined exceptions.
