如何绕过 ASP.NET 中按钮的验证？

Question

I have an ASP.NET form that takes input from a user. There's a Submit button on the form and a button called Calc which does a calculation to populate a text field. The problem I'm having is that on the form I have a set of <ASP:REQUIREDFIELDVALIDATOR> validators and when the Calc button is pressed the form gets validated. I don't want the required fields to be validated when the Calc button is pressed, only the Submit button. Any way around this?

Answer 1

将CausesValidation属性设置为 false。

Answer 2

<asp:Button runat="Server" ... CausesValidation="False" />

Button.CausesValidation （如果我没记错的话）。

Answer 3

Try putting CausesValidation="false" as a button attribute.

Some sample code:

Answer 4

ASPX Page:

<asp:Button ID="buttonNew" runat="server" Text="New" CausesValidation="False" />

OR

CodeBehind Page: (.cs)

buttonNew.CausesValidation = false;

Answer 5

Set the button.causesValidation to false.

However, if all it is doing is calculating something based on user input then you shouldn't have it posting back at all. I would recommend using an HTML button and attach some javascript to it to do your work for you and then you won't have this problem.

Answer 6

While designing the button, you can set its property CausesValidation="false" to avoid validation on button click event. It does not allow to validation the server control and perform its click event only

Answer 7

你应该用这个

UseSubmitBehavior="False"

Answer 8

To disable validation in a specific control

Set the control's CausesValidation property to false.

<asp:Button id="Button3" runat="server"
  Text="Cancel" CausesValidation="False">
</asp:Button>

To disable a validation control

Set the validation controls Enabled property to false.

To disable client-side validation

Set the validation controls EnableClientScript property to false.
