Two Way DataBinding to DropDownList

[raphael232]

Hi i'm playing around with the formview control to call my insert method of my business object. I notice that you put <asp:TextBox ID="txtTitle" Text='<%# Bind("Title") %>' runat="server"></asp:TextBox> to get the Title from a TextBox control but what do i bind to other controls such as RadioButtonList and DropDownList so that the values returned can be used in my insert method.

Appreciate the help. Thanks

Hi i found a solution to the above problem by using the SelectedValue property but now when i run my page i get:

Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.

Here the code:

<asp:DropDownList ID="lstCategoryID" SelectedValue='<%# Bind("CategoryID") %>' runat="server" DataTextField="Text" DataValueField="Value">
                        </asp:DropDownList>

and in my page load event handler:

Dim lstCategoryID As DropDownList = CType(FormView1.FindControl("lstCategoryID"), DropDownList)
lstCategoryID.DataSource = Utilities.GetCategoriesList(sectionID, 0, "")
lstCategoryID.DataBind()
