postback SqlDataSource

I am using the following ASP to connect to my database and populate my FormView.

I only want to do this when the page  is  NOT postback. How can I do this?

Here is the asp

 <asp:SqlDataSource ID="PeerAssementDB" runat="server"
        ConnectionString="<%$ ConnectionStrings:ReferralConnectionString %>"
        SelectCommand="spGeteerReviewMonthlyAll" SelectCommandType="StoredProcedure"
        UpdateCommand="spUpdateeerReviewMonthly" UpdateCommandType="StoredProcedure">
            <asp:ControlParameter ControlID="DropDownList_SpecDescription" Name="Spec_Desc"
                PropertyName="SelectedValue" Type="String" />
            <asp:ControlParameter ControlID="DropDownList_Status" Name="Status"
                PropertyName="SelectedValue" Type="String" />
            <asp:QueryStringParameter DefaultValue="P8" Name="OrgCode"
                QueryStringField="OrgCode" Type="String" />

The Sql Datasource should bind at run time. When the page is not postback then you can bind SQL database with the formview in page load event. like

formview1.DataSource = SQLdatasource1;
