使用必填字段验证器时如何清除控件？

Question

But since i have required field validators and regular expressions validator on the form I am not able to fire click event unless all validation are satisfied.

Answer 1

You can use the CausesValidation property

<asp:Button ID="BtnClearForm"
                Text="clear form"
                CausesValidation="False"
                OnClick="BtnClearForm_Click"
                runat="server"/>

Another option is to use javascript to clear your inputs .

Answer 2

将clear按钮的CausesValidation属性设置为false。
