Question

请任何人都可以查看我的代码并告诉我是什么原因导致itemCommand没有被按钮点击。

<div class="">
        <asp:Repeater ID="Repeater" runat="server" OnItemDataBound="Repeater_ItemDataBound" OnItemCommand="Repeater_ItemCommand">
            <HeaderTemplate>
              <div id="header" style="background-color:red">

              </div>
            </HeaderTemplate>

            <ItemTemplate>
             <div class="bms-car-item">

              </div>
              <div>
                  Car Type : <b>  <%# DataBinder.Eval(Container.DataItem, "VehicleGroup") %> class or Similar </b>
              </div>
              <div>
                  Car Group: <b> <%# DataBinder.Eval(Container.DataItem, "SupplierGroup") %></b>
              </div>
              <div>
                  Properties: 
                  <cp:CarProperties ID="CarPropertiesControl" runat="server" />
              </div>
              <div>
                  Price Before Voucher: <%# DataBinder.Eval(Container.DataItem, "PriceCust.Price") %> <%# DataBinder.Eval(Container.DataItem, "PriceCust.Currency") %>
              </div>
              <div>

              </div>

                 <div>
                     <a href="#" onclick="return ShowTerms()" >Additional Info</a>
                     <a href="#">Options Included in Price</a>
                 </div>
                 <asp:HiddenField ID="Selected" runat="server" value='<%# DataBinder.Eval(Container.DataItem, "VehicleModelCode") %>'></asp:HiddenField>
            </div>
            <div> <asp:Button Text="Select" ID="SelectButtonNext" CommandName="Get" runat="server" CommandArgument='<%# DataBinder.Eval(Container.DataItem, "VehicleModelCode") %>' /></div>
            </ItemTemplate>
        </asp:Repeater>
    </div>

Answer 1
