composite controls - Bug in VS.NET 2003 (FR) ?

[[XtOf].fr]

Hello World !

Without answers in my country (FRANCE), I hope that you'll have a response
to my problem !

I'm trying to create a composite control (WebControlLibrary) with VS.NET
ARCHITECT 2003 (FR).

Concerning the personalized properties, redrawing in the User Interface and
on the Web, there's no problems...

But I do not manage to recover one event created dynamically in the
CreateChildControl function !

The following example contains only the basic code for a composite
controls...

----

Protected Overrides Sub Render(ByVal output As
System.Web.UI.HtmlTextWriter)
EnsureChildControls()
MyBase.Render(output)
End Sub

Protected Overrides Sub CreateChildControls()
Dim btnTest As New
System.Web.UI.WebControls.Button
btnTest.ID = "btnTest"
btnTest.Text = "Cliquez ici pour voir !"
Controls.Add(btnTest)
AddHandler btnTest.Click, AddressOf test_click
End Sub

Protected Sub test_click(ByVal source As Object,
ByVal e As EventArgs)
DirectCast(FindControl("btnTest"),
System.Web.UI.WebControls.Button).Text = "Bravo !"
End Sub

---

When one clicks on the button, my code is executed and the button is well
redrawed (something like userscontrols) but the function test_click is never
called !!!!

I made the test on Windows 2000 professionnal (FR) and Windows XP Pro (FR).
I also made the test with CSharp... and : NOTHING!

It's also the same if you use a label, a linkbutton or I do not know what
anything else !

On the other hand, I did not test any other method than 'Code Behind'.

Moreover, the example of chapter 11 - vbcompositesnippet- of the french
version of book 'Creating Web applications...' (Microsoft Press France)
preparing with examination MCSD.NET does not function either...

Is it a Microsoft .NET Developpers's Team known bug ?

If so, is there a service pack available?

Thanks you for your help...

Hi,

does this control implement INamingContainer interface? If doesn't, put it
to implement that. It is needed for correct postback data routing in a
composite control.

Hi Teemu,

Thank you for your invaluable assistance for me !

However, don't you find abnormal that VS.NET 2003 doesn't implement
automatically INamingContainer when it create a New composite based on his
WebControlLibrary's Model?

But, the important thing is that it works now!
