Question

我在文箱上有一个水标。我在文本箱上安装了必要的外地有效器和监管机构。现在的问题是,当水标出现在方框中,用户点击纽子时,用户应当看到必要的信息而不是错误的信息。

But since there is some text in the text box, thus regex validator also gets fired. Can anyone tell me how can I achieve this ??

你可以使用这一法典。其工作罚款。

<div>
    <asp:TextBox ID="txtCustomerName" runat="server"></asp:TextBox>
   <asp:RequiredFieldValidator ID="RrequiredFieldValidator1" runat="server"
    ErrorMessage="Please customer name" ControlToValidate="txtCustomerName" ForeColor="Red"
    Display="Dynamic">
   </asp:RequiredFieldValidator>
   <div style="clear:both"></div>
    <asp:Button ID="btnSubmit" runat="server" Text="Submit Form" />
    <asp:TextBoxWatermarkExtender ID="wMarkExtndr"
    TargetControlID="txtCustomerName" WatermarkText="Enter customer name"
    runat="server">
    </asp:TextBoxWatermarkExtender>
</div>
