Event ID 3760

If I have some form control like textbox and I want the event handler to be located in the html instead of at the server side, how to do that? Of course I can copy paste javascript code in the aspx file. But is it possible to do that using some object oriented approach (ie programmatically in the code behind)?

Thanks

Hi,

I have grid view control that includes a dropdown control in a template field.

I wish to execute some code when the value is changed in the dropdown list.  Can't figure out how to capture this event though?

Any suggestions?

 Hello

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.

It seems lik

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();

 
EventHandler textChangedHandler = (EventHandler)Events[EventTextChanged];

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