Button click event not getting fired for a custom webpart where controls are added dynamically.
We are migrating from ASP.NET1.1/Sharepoint 2003 to ASP.NET 2.0/Moss 2007. We have a webpart on which controls are getting added dynamically. We have a button which is also dynamically added and a click event handler is also attached to it. However when we click on this button the page gets posted but the event is not fired. We analysed and found that the code to add the button in the webparts controls collection is executed but the code to add the button to it's container (that is a table) is not getting executed. Hence the event is not getting handled. If we forcefully add the bu...dynamically added linkbutton control, click event firing but cannot get page to open in iframe
I have a dynamically added linkbutton control (sorry for code layout, i get a noxmlhttp error when trying to use the source code box for posting) added like so:
Private Sub AddSecondLevelLinks(ByVal theTitle As String, ByVal theUrl As String)
Dim lb As New LinkButtonlb.Text = theTitle
lb.ID = lb.Text
lb.CommandArgument = theUrl
lb.Visible = True
lb.CssClass = "secondLevel"Panel2.Controls.Add(lb)
AddHandler lb.Click, AddressOf SecondLevelButtonClickEnd Sub
When i click the button my eventhandler definitely fires (drops in here in debug) but does not work as expe...Custom control adding user controls dynamically
I'm trying to develop a custom control in .NET 2.0 which builds a page based on an XML document. What it should be doing is looking through an XML file to see which user controls need to be loaded and where on the page they should go. The concept is quite simple and I had it working fine in .NET 1.1, but .NET 2.0 doesn't want to know. Loading the XML etc is all fine, but I'm really struggling to load the controls and get all their events to fire.I'm using Page.LoadControl and .Controls.Add(...) which does the job but I can't get all the events to fire in...Dynamic custom control on custom control
What I'm trying to do is create a module for use within a larger page. The page itself is an order form, which will have typical payment info (address, credit card, etc.), and the ability to select what you are paying for. Our clients will have several options in how they want the page setup. They can either have a single form, or they can have each module on it's own page. They can also have all the selected items fire in a single transaction, or have a seperate transaction for each item selected. And they can limit the total number of transactions a person can...Button click event not fired for a custom webpart where controls are added dynamically.
We are migrating a Sharepoint 2003 site to MOSS 2007 and ASP.NET 2.0. We have also migrated the webparts but they are still inheriting from Sharepoint.WebPart. We have a webpart where controls are added dynamically at runtime. On this webpart a button is added dynamically and a click event handler is also attached. The button on the webpart is displayed only when there is some data. The button deletes the selected row of data when clicked. But when we click on the button, the page gets posted but the event handler is not called. We analysed and found that the code where we add the button to ...Event not firing with Dynamic Controls in a Custom Web Control
I'm creating some LinkButtons on the fly (on Load) and they show up just fine. The problem is that the AddHandler event I created is not firing.

I have a peculiar problem and since I am just starting to use .net I am confident I am doing something wrong, but I can't see it and I've wasted a lot of time so far trying to figure it out. Hopefully one of you can figure it out.
I have a custom User Control and I am dynamically creating a RadioButtonList. If I remove the custom user control from the page the RadioButtonList works as expected and correctly. However, once I add the custom control, it does not fire the SelectedIndexChanged event.
Below is some code. If all I do is remove: "<UC:TOPMENU id="TopMenu1"...Custom composite contorl contains custom contols: controls collection gets empty (Or control get reinitialized) on postback.

In my page load, I call a function that loops through all text boxes, initializes them, and checks their IDs. If their ID matches certain values, I add an event handler and set AutoPostBack to True. It works fine if I call my function every time on Page Load. But if I only call it on NOT Page.IsPostBack (inital load), the event doesn't fire.
Can you post your code here..... If the event is not subscribed on control markup level then you have to subscribe everytime the page is postback.When the going gets tough - the tough gets going------------------------------...Dynamic control event no getting fired
Ok I just can't seem to work this out, I think I have an ok understanding of the lifecycle but perhaps not. In short, I'm creating a Button and trying to get it to fire an event, the event handler is never being called.
Here's what I've done
Declared my button as a Private
On class instantiation: Create the button as new Button(), set the Text property, set an ID

I'm sure this question has been asked a million times, but I haven't found anyone who had the specific problem I'm having. I've been having a problem with postbacks on controls that I have created dynamically at runtime. Here's the jist of it:
I have a page with a customized menu control that is declared in the .aspx file. When a user clicks on one of the LinkButtons in the menu, it sends an event to the page to load a control dynamically into a PlaceHolder on the page. That part works fine. However, if the control that is loaded into the placeholder has a postback event in it, raisi...Events Not Firing For Dynamically Added Controls!!
I was wondering if someone has had this same problem and if anyone had any ideas how to make this work. I am dynamically (programatically) adding a LinkButton control and an event handler for it using AddHandler. When the Linkbutton is added in the Page_Load or PreRender methods, the event fires. But if the LinkButton is added via another control event, not only does the event not fire, but my LinkButton disappears. The code is below:

I used to have a custom server control inhirted from TableCell control to implement click event in VS.NET 2003. When I use the custom control in VS.NET 2003 Web application (dynamically adding to table object), everything works fine. Below is the code from 2003 project, and everything works good in this way.

I have created a command button dynamically and assigned ItemCommand event for that command button, but that does not seems to get fired. I am unable to find the cause for it. This is the piece of code that I have written to create and assign event to the command button: System.Web.UI.MobileControls.Command cmdDownload = new Command();
cmdDownload.Text = "Download File";
cmdDownload.CommandName = "CommName";
cmdDownload.CommandArgument = "CommArg";
cmdDownload.EnableViewState = true;
