I'm having a problem with the "list" function when I type the line "preferredTheme.Value = ThemeList.SelectedValue" VWD 2010 says "ThemeList is not declared..."

This is particularly important because it's holding up development on an actual application I'm writing for work. In that case I have the same problem with the
"ViewListItems". What am I missing something?... other than just about everything... I'm less than a beginner.

Thanking you in advance... Lee

As I said in my personal e-mail on the same subject:

Cheers,

Imar

Imar,

Well there really isn't much other than what I posted... your example on Pg. 228 is as follows:

In the selectedIndexChanged event for the DDL per the exercise


Protected Sub ThemeList_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ThemeList.SelectedIndexChanged
Dim preferredTheme As HttpCookie = New HttpCookie("PreferredTheme")
preferredTheme.Expires = DateTime.Now.AddMonths(3)
preferredTheme.Value = ThemeList.SelectedValue
Response.Cookies.Add(preferredTheme)
Response.Redirect(Request.Url.ToString())
End Sub

I can't access the "ThemeList.SelectedValue" method Intellisense doesn't contain "ThemeList" and the error VWD 2010 throws is "ThemeList is not declared, it may be inaccessible due to it's protection level"

nuts... I just closed the BegASPNET/Wrox VWD app and now it I don't get an error. I say nuts because I was hoping that this was going to help me pinpoint the problem with my work app that I'm developing where I get a similar error but with the Listitem method... i guess I need to post that separately.

Where might I do that? I need to get a data item in code behind from a listview.

Thanks again for your super help.

Maybe Visual Studio hadn't picked up the changes in the Markup yet? When you run into issue like this, try compiling the site using Build | Build Web Site or Build SOlution.

The reason I asked for more code is the fact that the control you're targeting is defined in the markup. If you gave it a different name,such us lstThemes, it explains why IntelliSense couldn't find it.

Best place is in one of the general, non-book specific forums here: http://p2p.wrox.com/asp-net-4-539/

Cheers,

Imar
