That would help if I supplied more information:

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"

DataKeyNames="Map_ID" DataSourceID="SqlDataSource1"

EnableModelValidation

="True">

<Columns

>

<asp:ImageField DataImageUrlField

="Map_Location">

</asp:ImageField

>

<asp:HyperLinkField DataNavigateUrlFields="Map_ID"

/>

</Columns

>

</asp:GridView

>

<asp:SqlDataSource ID="SqlDataSource1" runat="server"

ConnectionString="<%$ ConnectionStrings:Way_FinderConnectionString1 %>"

SelectCommand

="SELECT Map_ID, Map_Location FROM Map_Table INNER JOIN Department_Table ON Department_Table.Department_ID = Map_Table.Map_ID">

</asp:SqlDataSource>
