Custom User Controls and dynamically created web controls events 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"...Web User Control dynamically generated control events won’t fire.
I hope someone can give me a hand on this one.
This is what I am trying to do:
We need to create a report. We are using a Repeater control to generate a custom grid. The columns and data fields won’t be known until run-time.
I’ve created a WebUserControl which contains a repeater control.
At run-time, I dynamically create templates for the header and data items.
On the header template I want to use a LinkButton so that data can be sorted when the user clicks on one of the header columns.
In my Header Template class, I have a reference to a list o...Problem in accessing web form data in user controls when create user control dynamically

Hi,I'll make this senario somewhat generic. I have an ASPX Page, within the aspx page I have two web user controls. "uc1" contains a datalist, on uc2 I have a form with a submit button. I want to fire the databind of the datalist in uc1 from the submit button on uc2, how can I do this?Thank you, New Orleans Hornets Season Ticket Holder!
"uc2" should raise an event that your Page can handle. Then, in the Page handler for this event, you can call the DataBind method of "uc1".Thanks, EdMicrosoft MVP - ASP/ASP.NET

Hi, I have 2 User controls on a page and want Control1 to call a method of Control2. Is this Possible?
Con1 = Datalist showing products, each with a Quantity Box and a Button.
Con2 = Repeater showing Cart Preview (name, Price)
When I click on the button on the DataList in Con1 it adds the item into the Session based Cart. However it does not update the Cart Preview. I need to call BindPreview() in Con2 in order to update the Cart Preview...
Does that make sense? argh! any help much appreciated!

Below is a block of code in my .aspx form named default.aspx. In this form I load a web user control. I then add it to a place holder control.(Lines 3 and 4 below) So how do I access the individual controls in my web user control? I want to set the properties on those controls, but I am baffled as to how to access the control. For example I have a text label control named "label3". How do I access this control.
Because for example, under certain situations I want to hide that control. ( Label3.Visible = false;)
