is there a event called 'ondrop'?

I have a Workflow that is using an InfoPath task form.  In the "FormEvents_Loading" method event handler I have some code that needs to run each time the form is opened.   I recycle the App Pool and open the form the code runs perfectly, but if I close and try to re-open the form the code is not run at all.  I can then recycle the App Pool again and on the next load the code executes just fine.   The code that is supposed to be run is a very simple statement to set a field value, so I don't think it is interfering.

Does anyone know what this might be?

Thanks,

I have a user control that contains another user control based on a button. When the button is clicked I have it show a context menu that is bound to a enumeration that shows a dynamic set of menu items. I use a HierarchicalDataTemplate to generate the MenuItems and use a style with an eventsetter to define a menu click handler to be called when any of the menu items are clicked. The context menu and its menu items gets displayed properly but the event handler is not getting called. Any ideas? Below is the section of the xaml where the user control is defined and below it is the code behind with the event handler.

Thanks!

Hi,

i am trying to develop a tool in C# which sets some properties for a printer when "Print" is clicked from any application.

Is there any event called when "Print" is clicked from any application?

How to get the control on Printer properties upon clicking "Print" ?

Any code snippets to achieve the above task will be helpful.

Thanks,

Hi everyone,

I'm relatively new to ASP.NET and I got stuck trying to create my first simple server control. I'm having a hard time capturing a CheckedChanged event of a check box in a GridView when wiring everything via code. I tried to create handler when creating new instance CheckBoxColumn : ITemplate class and in the handler of RowDataBound, the code executes but the event handler of the checkbox it is never called. If anyone would have any feedback on the subject it would be of great help.

Thank you,
Radek

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;
