Default Probs w/ AutoPostBack and DDL in Wizard Control

Hi everyone,

I'm reasonably new to ASP.Net 2, and I love the Wizard control, but I've come across an enfuriating problem, which was not a problem at all when I used the Multiview control.

I have two dropdownlists; the top one, when a selection is made, filters the list items of the second dropdownlist. Now this worked absolutely fine in MultiView, but when I ran the same code in a Wizard, the lists do not reflect the new SelectedIndex (i.e. the first one does not show the selection I just made and the bottom list is not filtered) and the form parameters do not seem to have been sent via the AutoPostBack.

I've searched the internet high and low for a solution to this. Is it a bug in the Wizard control? Can anyone help as I just don't seem to be able to find a solution to this problem. Any code would help too.

I am using ASP.Net2, SQL Server 2005 Express, and Visual Web Developer 2005 Express.

Depending on how you are filtering, you may need to use the UniqueID property of the control. Remember, you are essentially dealing with a control within a control and in some cases, especially when filtering, I've noticed you have to specify the UniqueID explicitly. For a wizard control, it will look something like Wizard1$DropDownList1. If you're not sure you can output the unique id to a label.

        Label1.Text = DropDownList1.UniqueID
