Question

任何人都可以帮我吗？当我在我的创建事件的tabcontainer上放置requiredfieldvalidator时，我无法更新我在另一个标签上的表单视图＆gt;＆gt;＆gt;编辑活动的标签。我完全不知道发生了什么，并且当我试错时，我发现requiredfieldvalidator是导致我的formview停止更新到我的数据库的那个。我和这个requiredfieldvalidator在另一个标签上，所以它是如何影响的？！？！？请指明或显示，因为我真的真的很新又坏！

以下是创建标签＆gt;＆gt;＆gt;

的代码

    <asp:TextBox ID="tb_eventName" runat="server" ValidationGroup="vg"></asp:TextBox>

    <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" 
                    ControlToValidate="tb_eventName" ErrorMessage="Enter event" 
                    ForeColor="Red" ValidationGroup="vg" SetFocusOnError="True" >*        </asp:RequiredFieldValidator>

        <asp:Button ID="bn_createEvent" runat="server"  
                    Text="Create Event" onclick="bn_createEvent_Click"    ValidationGroup="vg"/>`

以下是编辑活动标签的代码＆gt;＆gt;＆gt;

        <asp:FormView ID="FormView1" runat="server" CellPadding="4" DataKeyNames="eventID" 
                    DataSourceID="SqlDataSource2" 
                    OnItemDeleted="FormView1_ItemDeleted"   OnItemInserted="FormView1_ItemInserted" 
                    OnItemUpdated="FormView1_ItemUpdated" ForeColor="Black"   BackColor="White" 
                    BorderColor="#DEDFDE" BorderStyle="None" BorderWidth="1px"

添加requiredfieldvalidator后，它不会将我的formview更新到数据库

Answer 1

尝试将ValidationGroup添加到FormView中的按钮。与导致formview更新失败的必需字段验证程序相比，请确保使用不同的组名。

<asp:LinkButton ID="UpdateButton" runat="server"
    CommandName="Update" Text="Update"
    ValidationGroup="formViewValidation" />

这应该使它成为req。单击“更新”按钮时，不会触发vg的字段验证器。

修改：只是为了检查。如果在“更新”按钮上添加CausesValidation="False"会发生什么？

requiredfieldvalidator与formview冲突
