AddHandler not working

[Nathan Sokalski]

I have a section of my code that dynamically creates LinkButtons to allow
the user to go to the page containing a question they have not answered. The
code that creates the LinkButton is called, as well as the AddHandler line
(I ran a Debug and saw that it executes this code, and the links are
displayed on the page afterwards). However, the eventhandler is not called
when the LinkButton is clicked. Here is the code that dynamically generates
the LinkButtons as well as the eventhandler I want to be called:
'The code that generates the LinkButtons:
Private Sub btnSubmit_Click (ByVal sender As Object, ByVal e As

Me.submitanswer s()
If Me.completetest () Then
'Code that I use to update my database, not involved in this

Else
Me.lblAnswered. Text = String.Format(" {0} of 75 Questions
Answered (Not Answered: ", CStr(Me.questio nsanswered()))
Dim myconnection As New
SqlConnection(S ystem.Configura tion.Configurat ionManager.AppS ettings("connec tionstring"))
Dim cmd As New SqlCommand("", myconnection)
Dim qnumreader As SqlDataReader
Dim insertafter As Integer =

For i As Integer = 1 To 75

End Sub

Try changing the line

Dim questionlink As New LinkButton()

to

Dim WithEvents questionlink As New LinkButton()

Does that work?

No, if I add the WithEvents keyword I recieve the message:

'WithEvents' is not valid on a local variable declaration.

That was a good suggestion (when I read your reply I thought that might be
it), but unfortunately it wasn't. Any other ideas? Thanks.

Put the declaration of questionlink outside of the btnSubmit_Click code
block, in the general declarations area...

public withevents questionlink as New LinkButton()
inside your codeblock, remove the dim questionlink line.

you could also scope the linkbutton as public or friend.

does that work?

Nathan,

Here is a simple sample of dynamicly creating textboxes with events.

Will you be so kind if you send next time problems to these newsgroup to
show a simple sample instead of almost a complete sample. We want to help
you, however not doing a daytime job by investigating parts which are not
relevant to your question.

You apparently aren't to familiar with the programming modal of
ASP.NET? You need to use AddHandler to add the event listener before
the child control's event are handled (like in the Load event of the
Page), otherwise the dynamic event won't exist when it's time to
process it.

By the way, if you search the newsgroups before posting you could find
the answer on your own....

You have to tell it to AutoPostBack. Incidentally, you can use "With" to
save a bit of typing:-

If Not qnumreader.Read () Then
Dim questionlink As New LinkButton()

With questionlink

This is a LinkButton, it does not need or have an AutoPostBack property. And
take note that in my original post I stated that it does do a PostBack, it
just doesn't trigger the eventhandler I attempted to assign it.

[bruce barker]

asp.net pages are stateless. you rendered the linkbuton and added to
handler on the click event. but when the user links on th button and the
asp.net is run again, the page does create th linkbutton and add the
handler, so the event is ignored.

your code needs to remember it added the linkbutton and handler during
previous postback and recreate the linkbutton and handler during the
oninit event. you can save your state in session or viewstate.
