Dynamically add controls to user control based on Parent page button click event
I have a page which contains a button, a dropdownlist and a user control. The user control is added to the parent page during page_load. If the user clicks on the button, the value in the dropdownlist is passed to the usercontrol via the usercontrols public properties and is stored in its viewstate.
The user control is dynamically populated with fields based on a database id passed to it from the parent page.
I gave the user control a public property which hooked into the ViewState bag of the user control so that I could pass it the database id at r...Dynamically loaded user control with a button doesn't fire its button click event?
I have a datagrid, in which one of the columns is 'button' column called 'Send Email'. When I click on this button, then an email user control is dynamically loaded into a placeholder above the datagrid header area. The email control renders correctly, but when I click on 'Send' button in this user control, then the click event of this 'Send' button doesn't fire. This is even though the 'Handles.btnSend.Click' is there for the click method of the 'Send' button.
Can someone please tell me why the event is not firing and what do I need to do to make it fire?

I have an ascx control (that performs actions for an entity) being added dynamically to accordion panes, and then the panes are added to an ajax accordion control, so that the accordion can contain multiple panes with each pane containing one ascx control.
The ascx control contains a delete button which removes the entity from the database. Once the entity is removed, I need to reflect this deletion in the parent page by removing the accordion pane from the accordion. To do this I created a delegate function and which is called from the parent page to rebind the accordion and hence not d...Error when Loading Dynamic UserControl from current User Control's Button Click event Calling Page Event

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 ...User Control Button Click Event Does Not Fire With Postback, when Loaded 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.

Hi All, I have a panel in the masterpage which has a
modalpopupextender control associated to. There is a place holder
inside the panel to which i dynamically add User Controls on the click

fired.. in turn the Master page's Page Load is fired. I forgot to
mention that the link button, panel and modalpopup extender are inside
a Update Panel. Following is the code snippet:&nbs...Begginner question: adding user control via button click event after page load
I have a page with several user controls and a button. When the user clicks the
button, I'm adding an additional control to a placeholder in the click_event.
However, the problem is the event handler is fired after the Page_Load event,
so the additional control does not show.
Being a beginner, I'm not sure what the usual way to approach this would be?
Should I somehow try to fire the click event handler before the Page_Load
event, or at the end of the click event should I somehow re-draw the page at
