I want to show the error message.

    I think this is the problem, set this property to true

      EnableClientScript="true"

    Update:Got your problem, it is the validationGroup, either add validationGroup property to validationSummary or remove valiationGroup from RequiredFieldValidators

    <asp:ValidationSummary runat="server"  ID="update" DisplayMode="BulletList" ValidationGroup="update"/>
<asp:ValidationSummary runat="server"  ID="save" DisplayMode="BulletList" ValidationGroup="save"/>
