You are going to have to format the values when you bind them in your repeater.
So something like this: (Assuming you have a MinPrice & SaleDate column in your dataset.)
<asp:label id="Label1" runat="server" text='<%# String.Format("{0:C}", Eval("MinPrice")) %>'></asp:label>
<asp:label id="Label2" runat="server" text='<%# String.Format("{0:d}", Eval("SaleDate")) %>'></asp:label>
