<ItemStyle Width="120px"></ItemStyle>
<ItemTemplate>
<asp:Label ID="qssj" Runat=server Width="90px" Font-Name="宋体" Text='<%# DataBinder.Eval(Container.DataItem,"qssj") %>'>
</asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="qssjedit" Runat="server" Width="80px" Height="20px" Font-Name="宋体" Text='<%# DataBinder.Eval(Container.DataItem,"qssj") %>'>
</asp:TextBox>
<asp:requiredfieldvalidator id="qssjRequiredfieldvalidator" runat="server" ErrorMessage="请输入起始时间!" ControlToValidate="qssjedit">*</asp:requiredfieldvalidator>
<asp:regularexpressionvalidator id="qssjRegularExpressionValidator" runat="server" ErrorMessage="起始时间日期格式错误!" ControlToValidate="qssjedit" ValidationExpression="\d{4}-\d{2}-\d{2}">*</asp:regularexpressionvalidator>
<asp:CompareValidator ID="qssjCompareValidator" Runat="server" ErrorMessage="起始时间无效" Type="Date" Operator="DataTypeCheck" ControlToValidate="qssjedit">*</asp:CompareValidator>
</EditItemTemplate>
</asp:TemplateColumn>
