Interaction with UserControls (ascx)?

[Frank Schumacher]

Hi NG,

I have 2 problems working with an user control (ascx) and couldn't find
a solution yet.
I created a simple ascx with some ImageButtons and drag it on a simple
Webform, this code was inserted:

<%@ Register TagPrefix="uc1" TagName="chunk_container"
Src="chunk_container/chunk_container.ascx" %>

and in the body-tag:

<uc1:chunk_container id="Chunk_container1"
runat="server"></uc1:chunk_container>

1.) the Page_Load function of the ascx isn't execuded. It seems that the
ascx doesn't receive the event

2.) as shown above, an instance of my UserControl is created within the
body-tag, but I do not have any reference in my code behind. I'd expect
something like
protected Namespace.chunk_container Chunk_container1;

but there ain't such declaration. So I cannot access the functions, that
are public in my UserControl (and essential for the use of it).

I'm afraid, that I am completely out of line and hope, someone here can
give me a clue, how to solve this problems.

Thanks in advance,
Frank

PS: I am using VS.NET 2003, C#, W2003

What does your @Control tag in the User Control look like?

2.) as shown above, an instance of my UserControl is created within the
body-tag, but I do not have any reference in my code behind. I'd expect
something like
protected Namespace.chunk_container Chunk_container1;

Sadly, you have to add that manually. :-/

Hallo Scott

What does your @Control tag in the User Control look like?

I have checked the statement and found an "AutoEventWireUp" Attribut
which was set to false. After changing it to true, the user control got
its events.

Sadly, you have to add that manually. :-/

As long as I know that I have to add it manually, it is no problem. Now
I know it, so no problem anymore ..

I have done it and found some answers, even on questions that might be
arise in the future ...

Happy Programming!

It became a bit happier now .. thanks for the input!

Hi Saravana,

thanks for the link! It wasn't exactly what I was looking for, but
interesting anyway. I just don't understand, why the author mourned
about not being able to use inline server scripting. Why would anyone
use inlining now that we have code behind?

Ciao,
Frank
