Question

所有。这是我第一篇StackOverflow的帖子。伟大的网站，并经常帮助我，但我找不到答案。

我有一个带有TextBox的asp.net表单，它有一个RequiredFieldValidator。在此之后是启用了编辑和删除的DetailsView。文本框不在DetailsView内。单击“编辑”和/或“删除”命令时，我需要触发RequiredFieldValidator。

这是我的两个控件的代码。我可以用后面的代码发布所有内容但如果不需要则发布很多。

TIA的帮助。

     <asp:LinkButton ID="LinkButton2" runat=server Text="Edit" CommandName="edit"/>
     <asp:LinkButton ID="LinkButton1" runat="server" Text="Delete" CommandName="delete" OnClientClick="return confirm ( 'Are you sure you want to delete this record?' )"/>
    </ItemTemplate>
   </asp:TemplateField>

Answer 1

下午好，我相信如果你在DetailsView和RequiredFieldValidator中设置了两个按钮的ValidationGroup属性，当点击按钮时，验证器应该激活它的validate事件。 ValidationGroup属性可以是您要描述您尝试验证的验证组的任何字符串。

Answer 2

您必须对要验证并且验证的所有控件进行分组。如果您要验证 LinkButton 上的 TextBox ，请点击您必须设置 TextBox 的 ValidationGroup 属性想验证和使用相同值（任何字符串）进行验证的 LinkButtons 。

<asp:TextBox ID="txtReason" runat="server" Width="500px"></asp:TextBox>

<asp:DetailsView ID="dvCOHDetail" runat="server" Height="50px" Width="700px" DataKeyNames="RecID" DataSourceID="sdsCOHIncident" AutoGenerateRows="False" OnDatabound="dvCOHDetail_DataBound" AutoGenerateEditButton="False" AutoGenerateDeleteButton="False" OnItemUpdated="dvCOHDetail_ItemUpdated"  OnItemDeleting="dvCOHDetail_ItemDeleting">
    <Fields>
        <asp:TemplateField HeaderText="ACTION:">
            <ItemTemplate>
                <asp:LinkButton ID="LinkButton2" runat="server" ValidationGroup="ValidationGroup1" Text="Edit" CommandName="edit"/>
                <asp:LinkButton ID="LinkButton1" runat="server" ValidationGroup="ValidationGroup1" Text="Delete" CommandName="delete" OnClientClick="return confirm ( 'Are you sure you want to delete this record?' )"/>
            </ItemTemplate>
       </asp:TemplateField> 
    </Fields>
</asp:DetailsView>

<asp:RequiredFieldValidator ID="rfvReason" runat="server"  ControlToValidate="txtReason"
    ErrorMessage="Reason is required for Edit/Delete" ValidationGroup="ValidationGroup1" EnableClientScript="False"></asp:RequiredFieldValidator>

文本框外部DetailsView - RequiredFieldValidator未触发
