Event Handling

[kenbw]

I'm trying to use event handling with a user control so that I can Raise an Event that the Webform the has the Control on it sees. The event raises fine within the web control, but I never see that event get fired on the Webform side. Does anyone have an idea as where I should start?

I have declared the Events on the Webform from the Control as Follows:

Protected WithEvents UCSearch1 As Newfx.SearchTool

Then I also have a sub that I thought would deal with the Event:

Private Sub UCSearch1_DDLUsersListChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles UCSearch1.DDLUsersListChanged

'Business Logic

End Sub

Thanks in advance for any help.

Hey,

I have done something slightly similar where I made the controls in the user control public and then set the method I wanted to fire in the containing page. I would certainly like to find a better way to it (I am having to do too much work for the benefit of the control).

So basically in the user control I have image button controls which I set as public. Then in the containing page I put the event handler identification code in a pagePrep function. I don't have the syntax handy but it is the same as what is put into the InitializeComponent section generated by VS.

Please update this thread if you come up with a good solution as I would like to improve my solution to this problem.

Crystal,

I actually fgured out my solution on usings Events and it is very easy and clean to do once I figured out all the issues involved. The samples I used to finally figure it out were at O'reilly.com. Here is the link:

http://www.oreillynet.com/lpt/a/dotnet/excerpt/progsapdotnet_14/index1.html

What my problem ended up being was that I had misnamed a WithEvent on the WebForm side so it did not catch the UserControl raised event. It really is very easy once you work through it.

I don't know the best way to explain it without a lot of code so if after you look at the link you still have questions please let me know I'll be happy to answer.

I am experiencing the same problem (not being able to see events from the UserControl on the web form), but unfortunately, the link provided here gives me only a server error.

Anyone figure this out?

Thanks,
Stacey
