[RESOLVED] [2005] Dynamic control event handle problem.

[Jigabyte]

Hi All,

I am creating a set of controls dynamically from a database. The controls comprise of a panel (container) an image, a link button and a label. This all works great. I have also per link button control added a handle:-

AddHandler MinLnk.Click, AddressOf MinLnk_Click

This is being created for each of the link buttons created so that they all call the same MinLnk_Click event.

As I create the controls I also store in an array a unique code for each MinLink control which is then used to show the new page when the link button is clicked on.

My problem is I need to identify which linked button is being pressed so I can us the correct code. They all call the same MinLnk_Click event and I can't make them call a different one because this would be variable not static.

So in brief I can create one or ten link buttons depending on what is in the database. I store per button a article code in a array. I create a click handle which calls MinLnk_Click for each of the controls. I need to identify which button is being clicked so I can use the correct article code when it reloads the default page.

I used master page and content page and session parameters to get the correct article.

Thanks for any help,

Jiggy!

I have also noticed that when I click on the link button it does not call my sub routine.

Now I am really stuck,

The Sender argument of your event handler procedure should have the reference of the control that fired that event.

Hi Mate,

Can you be a bit more specific. Whem I do sender. I get very little options.

Cheers,

Jiggy!

You get very little options because sender is of type OBJECT. That is the ultimate base class of any object. You should typecast it to appropriate type so that you can do something useful with it.

Since you know that it is a link button, we typecast it to LinkButton

Dim myLinkButton as LinkButton = CType(sender, LinkButton)
'So now you can use the myLinkButton as you would normally have used your link button.
'e.g.
Response.Write(myLinkButton.ID)

Thank you very much mate, that works fine.
