Newbie: OnClick reassignment

Ted Singh · Dec 4, 2004

Is there anyway to dynamically change the OnClick method for an object? I
keep getting a BC30390 compilation error.

Essentially what I'm trying to do is dynamically put up buttons on the page
w/o putting <asp:ImageButton ...> in the html. Is there a better way?

Here is a snippet of my code:

<script ...>
sub Page_Load(Sender as Object, e as EventArgs)
dim i as integer
dim myButton as ImageButton

for i = 1 to 3
myButton = New ImageButton()
myButton.ID = "Button" & i
myButton.CssClass = "button" & i
myButton.OnClick="btnOnClick" & i
myForm.Controls.Add(myButton)
next

sub btnOnClick1(Sender as Object, e as EventArgs)
'do something really cool
end sub
</script>

<html>
...
</html>

This question would be better likely to get an answer on
..scriptiong.vbscript or one of the groups with "dhtml" in their names. It
has nothing to do with ASP, which is server-side technology. For future
reference, if you can reproduce your problem with a .htm file, you are not
having an ASP problem.

To answer your question, you need to use GetRef() to assign an event handler
to an object with vbscript. Like this:

myButton.OnClick= GetRef("btnOnClick" & i)

Please follow up in a client-side script newsgroup.

This is a dotnet question, not a classic ASP question. You are more
likely to get help from the clever bods in a dotnet news group.

Of course! I missed the "as ..." parts. This is vb.net, not vbscript. D'oh!

Sorry for posting in the wrong place ... I'll post in VB.NET or .NET in the
future.
