Dynamic Controls and their events

Hello,

I'm trying to handle click events with button controls I've created
dynamically. I've found two ways of dealing with them, neither of which I
like, so I'm asking if anyone knows a better way.

1), register a handler for the click event, as so

Dim btnClick As New Button
btnClick.Text = "Delete"
btnClick.ID = "myButton"
AddHandler btnClick.Click, AddressOf Button_Click()
anotherControl. controls.add(bt nClick)

Sub Button_Click(By Val sender As System.Object, ByVal e As System.EventArg s)
Dim btn As String = CType(sender, Button).ID
myLabel.Text = "The Button " & btn & "was clicked."
End Sub

This works great, but only one "big" problem, I have to rebuild these
controls on postback for the events to fire. Well that does me no good if
on postback, I don't want this control to appear anymore! Lets say I had a
list of items, and my dynamic control was a delete button. If I click this
delete button, I want the item deleted, which would naturally mean the
delete button would need to be gone too.

2), use client side JavaScript, register onClick attributes for each button
to update a hidden field and submit the form, then on postback, retrieve the
hidden fields value, and work accordingly. Much like this example:

http://weblogs.asp.net/ksamaschke/ar...2/18/2595.aspx

This works..ok, but gets a little messy when you have to deal with multiple
events for multiple buttons that all do something different.

Surely there is a better way!, hopefully using something like the first
method, but not needing to rebuild the buttons.

Any help would be appreciated!

I have been working for quite some time on this issue which in theory should be quite simple. The problem is that the Cancel and Save events are not fired when their respective buttons are clicked. I have read several posts which say to put your column generating section in the Page_Init section and it will solve the problem....however, it hasn't solved mine. Can somebody please take a look at this and provide any insight if possible?

I have problems in understanding the behavior of the events triggered by dynamically created controls over a webform. Could you help me? In a webform, I have a static PlaceHolder PH containing a table of controls, dynamically generated. Among these, a linkbutton (LinkBtn) to which have attached a click handler method, LinkBtn_Click(...) . Generally it works fine, but if in the LinkBtn_Click(...) code I try to access a webform control,...

I have created several grids dynamically and have added them to different HTML placeholders on a vb.net web form. The grids and controls within them come up and view beautifully when the web page first starts, but when I click on a button, and the page comes back, my dynamically created grid and controls are not visible. Any thoughts? Please view my sample code below. If Not ispostback then creategrids end if

Hi, I've searched the newsgroup and other sources to understand how to handle runtime controls and see I'm not the only one who's confused, but I'm still not quite sure of the best way to handle from all the various explanations/answers. I'm attempting the typical scenario... I create a variable number of controls at runtime based on parameters from a database.

Hi everyone! I've made quite a lot of research on this, and I've tried a couple of proposed solutions. Nothing has worked for me, but I feel there's not much I'm missing. So I'm turning to this group and its experts for answers. So : - I've got a main page (main.aspx) - On this page, I've got a button (btnArchive), on whose click I dynamically add a UserControl (archive.ascx) to the main page.

Hi, I'm working in C# .net 2005 with Ajax. I have a page that loads dynamic user controls depending on the scenario. In those user controls, I create dynamic linkbuttons. The user controls are loaded on the .aspx PageLoad and the linkbuttons are created on the .ascx PageLoad. The problem I have is that those linkbuttons don't work on the first click. I have to make 2 clicks to have their event fired. What can I do for that ? Thanks.
