方法一:
//日期格式yyyy-mm-dd
<asp:rangevalidator id="vldRngDate" runat="server" CssClass="main" ErrorMessage="日期必须在1900~2500之间" ControlToValidate="txtDate" Display="None" MinimumValue="1900-01-01" MaximumValue="2500-12-31" Type="Date"></asp:rangevalidator>
方法二:
//验证是否为空
<asp:RequiredFieldValidator id="RequiredFieldValidator1" runat="server" ErrorMessage="RequiredFieldValidator" Display="Dynamic" ControlToValidate="TextBox"></asp:RequiredFieldValidator>
//工具箱--->选择CompareValidator-->ControlToValidate为需要验证的输入框-->Operatoe为你要验证的方式-->Type为你需要验证的类型
//验证是否是日期格式的
<asp:CompareValidator id="CompareValidator1" runat="server" ErrorMessage="CompareValidator" Display="Dynamic" ControlToValidate="TextBox" Operator="DataTypeCheck" Type="Date"></asp:CompareValidator>
方法三:
//正则表达式
//出错警告并允许焦点离开：
<asp:TextBox>< id="textbox1" onChange="ValidateDataType( 'Date' ) " runat=server>
</asp:TextBox>
//出错警告并不允许焦点离开：
<asp:TextBox>< id="textbox1" onBlur="ValidateDataType( 'Date' ) " runat=server>
</asp:TextBox>
