Looking at mvc examples is pointless if you're using webforms as there is rarely an easy one-to-one conversion. You haven't provided enough information on where the data comes from and the controls are bound to their data in different ways. Rather than "converting" you're really looking at re-writing. So there is no point looking at examples that you need to rewrite, just try and find webforms examples of what you're doing, there are loads of examples around simple forms.
<asp:Hyperlink Navigateurl="yourcreatepage.aspx" Text="Create" runat="server"/>
<form method="post" runat="server">
Genre: <asp:Dropdownlist ID="ddlGenre" runat="server"/>
Title: <asp:Textbox ID="txtSearchString" runat="server"/>
<asp:Button ID="btnSubmit" Text="Filter" runat="server"/>
That is just the UI though, what happens to the data or how the dropdown gets populated is up to you, you didn't provide enough info to reproduce. Like I said above though, just stay away from MVC examples.
