accessing databound property from inside normal ASP.NET script block

im trying to do the following:

<asp:DataList ID="DataList1" runat="server" CellPadding="4" DataSourceID="SqlDataSource3"
            ForeColor="#333333" Width="100%">
            <FooterStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
            <SelectedItemStyle BackColor="#E2DED6" Font-Bold="True" ForeColor="#333333" />
            <asp:Label ID="FilenameHeader" runat="server" Text="Attachments"></asp:Label>
                <asp:HyperLink ID="HyperLink1" runat="server" Text='<%# Eval("Filename", "{0}") %>' NavigateUrl='<%# "~/images/" + Eval("TicketID", "{0}") + "/"+ Eval("Filename", "{0}") %>' Target="_blank"></asp:HyperLink><br />
                <% string temp = <filename string>
                   if (temp.Substring(temp.Length-3,3).ToLower().Contains("jpg"))
                <asp:Image ID="Image1" runat="server" ImageUrl='<%# "~/images/" + Eval("TicketID", "{0}")+ "/"+Eval("Filename", "{0}") %>' Height="50%" Width="50%" /><br />
                <%} %>
            <AlternatingItemStyle BackColor="White" ForeColor="#284775" />
            <ItemStyle BackColor="#F7F6F3" ForeColor="#333333" />
            <HeaderStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
        <asp:SqlDataSource ID="SqlDataSource3" runat="server" ConnectionString="<%$ ConnectionStrings:SupportTickets %>"
            SelectCommand="SELECT [Filename], [TicketID] FROM [Attachments] WHERE ([TicketID] = @TicketID)">
                <asp:ControlParameter ControlID="GridView1" Name="TicketID" PropertyName="SelectedValue"
                    Type="Int32" />

i need to set 'temp' to equal the value of 'Filename'. how do i do that? basically i only want to render the image control if the filename is an image.

why dont you add both databound controls and show/hide based on your condition
should be easier this way

that's another way to do it, but it doesnt help me with the condition part. i still dont know how to determine if the filename contains a certain extension. can anyone show me how to do that?
RepriseMISAuthor Commented:
ok, i figured it out:

added this to asp:Image -
Visible='<%# FileIsImage(DataBinder.Eval(Container.DataItem, "Filename")) %>'

and this to top of file

<script language="C#" runat="server">
    bool FileIsImage(object filename)
        string file = (string)filename;
        if (file.Substring(file.Length - 3, 3).ToLower().Contains("jpg"))
            return true;

        return false;


now it sets the visibility of the of the image control depending on if the filename has that extension. thanks for your suggestion sammy. i'll give you the points.
