drop down list question.
 

Using Visual Web Developer, I am wanting to use a Drop-Down list on a Web Form. I know how to use HTML to create and add items to a Drop-Down list. The problem is that I need to populate the list from a database. So I used a DropDownList control from the menu. I specify where the database is and which table and columns to use. The problem I am running into, and not seeing any fix for, is that I need to be able to select an item and automatically be linked to another page. I set a table in my DB to be a hyperlink field, but that does not seem to work. I set the AutoPost to true, but all that seems to do is refresh the page. I am guessing that it is trying to place data on the same page, but that is not what I need.

So basically, all I need is a Drop Down that gets populated from a DB, and when a item is selected in the Drop Down it links to another page. Sounds easy, huh?

I need someone who is smarter than me. Can this even be done? Please help. Thank you.

Using the AutoPostBack, check the value of the drop down box. Something like this:

    protected void Page_Load(object sender, EventArgs e)

    {

        if (Page.IsPostBack)

        {

            if (DropDownList1.SelectedValue == "foo")

                Response.Redirect("somepage.aspx");

        }

    }

Or, if you use VB:

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        If Page.IsPostBack Then

            If DropDownList1.SelectedValue = "foo" Then

                Response.Redirect("somepage.aspx")

            End If

        End If

    End Sub

I think I understand that, still learning codes. What does "foo" do? Thanks, I will give this a try.

It still sort of refreshes the page.

foo is a value to compare against. You'll want to replace it with whatever value you have, and other values with else if statements. And I'm totally out of the habit of writing code. Those should be DropDownList.SelectedValue.Equals("foo") rather than using == and = :icon_redface:
