asp.net的验证控件出现问题 [英] Problem with the validation controls of asp.net

问题描述

我将验证控件放在我的网页中..

这样，当我单击添加产品"按钮时.我可以在验证摘要中显示错误..

但是问题是，如果我在页面上单击任何其他链接或按钮以转到其他页面..这将迫使我在我验证的文本框上写..

我希望他们仅对添加产品按钮起作用.对我单击的其他链接不起作用.
我该怎么办..这是代码.

i put validations controls in my webpage..

so that when i click Add Product button . I can show Errors in Validation summary..

but the problem is that if on the page i click on any other link or button to go to some other page.. it will force me to write on the textboxes which i validate..

i want them to work only for add product button.. not for the other links i click.
how can i do it.. here is the code.

<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
    <style type="text/css">
    .style4
    {
        width: 100%;

推荐答案

设置 ^ ]属性设置为false ，以便您可以执行操作而无需执行验证.

Set the CausesValidation[^] property of the control to false so that you can perform action without validation is performed.

您需要将属性CausesValidation添加到您不想受到验证影响的控件中，并将其设置为 False .

那应该做到的.

You need to add the attribute CausesValidation to those controls you do not want to be affected for validation and set it to False.

And that should do it.
