I have a number of rad docks on a portal page, each of the docks contain a WebUserControl. Each of these controls are configurable by the end user.
one example is a user adds a rss feed control and they then choose the geographical location of the news they want the feed to show. The user can add multiple rss feed control to the portal page each with different settings. I need a way if capturing the uniqueid of each control so I can retrieve the correct configurations setting form the database.
any examples n vb.net please
thanks

Hello Martin,
Have you tried accessing the control's ClientID property to save the client id? I'm not sure of your exact implementation, but if you want to save a user's settings in a user control after the user saves them, you might give this a try. Bubble the Click event from the user control to the page along with any data you want to be able to access there. Add an event handler to handle the event and save the settings and control information to your database.
In this example I created a simple form which allows a user to input numeric values. I have bubble up the Click event of the Button to the page and made accessible the value the user entered in a custom object which inherits from the EventArgs object. When handling the event at the page level, I now have access to the ClientID property of the user control and the data entered by the user.
I know this example may not be exactly what you wanted to do, but hopefully it will help point you in the right direction. Please let me know if you continue to have trouble.
Sincerely,
Kevin Babcock
