我做错了什么？

   <asp:Panel ID="pnlProductUnits" runat="server" Width="100%">


         <asp:Repeater ID="repProductUnits" runat="server" EnableViewState="true" onitemcommand="Button_ItemCommand">

我怀疑您的问题与验证者有关，知道DropDownList的原始选择是什么以及是否已选择某些内容。您可能需要将InitialValue添加到必填字段验证程序。

<asp:RequiredFieldValidator ID="RequiredFieldValidator1"
     runat="server" ErrorMessage="*" Display="Dynamic" Text="*" 
     ControlToValidate="ddlSecondaryUnit" ValidationGroup="grpQuantity" 
     ForeColor="#FF3300" InitialValue=""></asp:RequiredFieldValidator>

根据您的DropDownList的数据源，该值可能类似于＆＃34;请选择＆＃34;或者只是空白。

下拉列表中的RequiredFieldValidator不起作用
