Dropdownlist in Listview

Zones: .NET Framework 3.x versions, Microsoft Visual Studio Express

Tags: Vb.net 3.5, IE7

I am using VS express web developer .net3.5. I have a datalist on the page and have changed 2 textboxes in to dropdown lists. I can populate the data in the dropdowns without an issue but I cannot bind it back to the database. With the code below I get the following error message:
Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.
I need to fill the dropdownlist from my db and write the data back on insert.

         
             <asp:DropDownList ID="plantTextBox" runat="server"
                        DataSourceID="SqlDataSource2" DataTextField="plant_id" 
             DataValueField="plant_id" Text='<%# Bind("plant") %>' />

I just noticed, DropDownLIst does not have a Text property... what exactly are you trying to do?

Comment by Shepwedd

I solved this. You're not finding your control correctly. Use the attached to base your iteminserting event on...

         
             protected void ListView_ItemInserting(object sender, ListViewInsertEventArgs e)
    {
        DropDownList ddl = (DropDownList)ListView.InsertItem.FindControl("DropDownList");
        e.Values["VacancyID"] = ddl.SelectedValue;
    }
