Event not raised while parsing xml file



In Visual Studio 2010 ASP.NET 4.0

I want to write a procedure to validate a xml file with a xsd. I found some examples on the web but the one i chose does not work as attended. The example uses XmlReader with a XmlReaderSettings and a ValidationEventHandler.

Here is the code

Protected Sub VerifyDes(ByVal filename As String)

        Dim xslDes As XmlReaderSettings = New XmlReaderSettings()
        xslDes.Schemas.Add("", "http://www.mysite.com/xsd/ValidData.xml")
        xslDes.ValidationType = ValidationType.Schema
        xslDes.ValidationFlags = XmlSchemaValidationFlags.ReportValidationWarnings

        AddHandler xslDes.ValidationEventHandler, AddressOf xslDesValidationEventHandler

        Dim des As XmlReader = XmlReader.Create(filename, xslDes)

        While (des.Read())

        End While

    End Sub

    Protected Sub xslDesValidationEventHandler(ByVal sender As Object, ByVal e As ValidationEventArgs)

        'some code here
    End Sub

I tested this procedure with a xml file which was well formed but contained some elements which were not conform to the xsd.

No event or error occured. It said the file was valid.

Then i tested with a badly formed file. A XmlException was raised but nothing happened with the ValidationEventHandler.

Composite control: How to bubble a textbox's TextChanged event?


I've created a composite control that contains several controls, including a textbox. I'm trying to expose the TextChanged event of the textbox as an event on the composite control. I understand that events can be bubbled up the control hierarchy and handled at a higher level, which I've attempted to do, but I can't get the bubbled event to fire. When I drop the control on an aspx I can see the TextChanged event, I can subscribe to the event, but nothing ever happens. Any suggestions? Here is what I think is the relevant code:

// My event
private static readonly object EventTextChanged = new object();

//Handle the bubbled event
EventHandler textChangedHandler = (EventHandler)Events[EventTextChanged];

protected override bool OnBubbleEvent(object source, EventArgs e) 
    bool handled = false;

Cant find vsi file for CSS Friendly Control Adapters


Hi guys

This is driving me crazy... I cant find the .vsi file for installing the CSS Friendly Control Adapters Project. Does anyone know where I can get this?

The following link: http://www.asp.net/cssadapters/ only leads to the CodePlex wiki where I can download the dll and a partial solution. Essentially, I'm looking for the source code to implement the Menu adapter.

Any help is much appreciated!

For a control which events are raised at design-time, run-time or both?

Hi. I have been getting several different errors on the my windows forms designer. I'm trying to implement an application with some complexity on the screen navigating since it includes several main views as also sub-views in which the sub-views are represented by user controls. I believe that some of my errors are related to the fact that I miss important information related the events that are raised while working in the windows forms designer. Is there any link that includes information about the events of a control that are raised at design-time, run-time or both? For example, if I override the OnLoad() method of a User Control, that method will be executed both at design-time and run-time. Knowing about this information has helped me resolving an issue related to duplication of columns on a customized DataGridView. Not 100% sure if it's possible to obtain what I'm asking for or if this information exists. If this information is not available what could I do in order to understand in more detail the kind of events that are raised in the design-time vs run-time? Can I debug an application in design-time using Visual C# 2008 Express Edition? I found this link that helps identifying the run-time and the design mode: http://dotnetfacts.blogspot.com/2009/01/identifying-run-time-and-design-mode.html This link has been helpful but I still feel that I need more information.

Binding an event method from a control in a seperate window

How would you bind a event method from a control back to a seperate window?  I have a ActiveX control hosted in a WindowsFormsIntegration wrapper.  That is operating in its own window along with all its events.  The properties of the control are handled by a class that defines the dependency objects (thanks Bob) to provide a view model between it and a window with controls for setting/getting those properties.  Since events constrained to Window 2, is it possible to bind the events back to Window 1?
