Question

我有一个asp：Fileupload和一个asp：RequiredFieldValidator来强制用户选择一个文件。它在IE上运行正常，但使用Chrome或Firefox时，requerired字段验证器仍然显示错误...

<asp:FileUpload ID="FileUpload1" runat="server" CssClass="clsFileSelect" Width="255" />
<asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" Display="None"
       ControlToValidate="FileUpload1" ErrorMessage="É necessário seleccionar o ficheiro a anexar." ValidationGroup="AnexarDocumentos" SetFocusOnError="true" />

任何想法？

Answer 1

删除ValidationGroup属性，它应该有效。

祝你好运！

Answer 2

尝试将与ValidationGroup相同的RequiredFieldValidator添加到asp:FileUpload

<asp:FileUpload ID="FileUpload1" runat="server" CssClass="clsFileSelect" Width="255" ValidationGroup="AnexarDocumentos" />
<asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" Display="None"
   ControlToValidate="FileUpload1" ErrorMessage="É necessário seleccionar o ficheiro a anexar." ValidationGroup="AnexarDocumentos" SetFocusOnError="true" />

RequiredFieldvalidator总是为firefox和chrome中的asp：FileUpload触发
