ASP.NET 2.0 Raising a custom event from a usercontrol to parent page: How?

Hi all, I have a user control which I want to raise a custom event from so
the parent page can reload a datagrid with some new information.

In the 1.1 framework days I would have just done something like the
following in my user control:

public delegate void _departmentClic k (object sender, int e);
public event _departmentClic k DepartmentClick ;

And then called the DepartmentClick event when I wanted to inform the parent
page.

Then in the parent page I would have explicitly created the usercontrol and
created an event handler for the DepartmentClick event. No worries...

How the hang do I do the same thing in ASP.NET 2.0?

I can create the delegate etc no problem in the UserControl but in the
parent page, how / where do I create the event handler???

TIA
Mark

Hi all, I fixed my own problem, it is pretty much the same as 1.1. I just
did not have to declare an instance of the user controls as asp.net 2.0
automatically picked up that there was an instance of the user control on
the page.

Cheers

I have a UserControl that contains a calendar control. The calendar is not raising events (month navigation, date selections, etc.). I've checked that the OnSelectionChanged event has a handler being registered. Is there anything else obvious or otherwise that I've missed? Is there a problem using it in a UserControl? Thanks Colin

I did a ton of searching to try and find a simple solution to this issue and finally wrote my own, which I am sharing with everyone. In my searching, I did find a very complete and robust solution at http://weblogs.asp.net/asmith/archive/2003/09/15/27684.aspx but it was far more complex then I needed. (I got lost trying to figure it all out). Therefore, here goes my simple "web dialog box with parent event handler fireing" solution. ...

I am experiencing some strange behavior between a UserControl's validating event and a treeview control.

I took the sample from that article and recreated the situation I see in my application. (Code included below.) If you run the...

These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers.
