推荐答案

我认为您没有阅读ConfirmButton的文档.从ASP.Net检查示例，不要忘记阅读ConfirmOnFormSubmit属性.

ConfirmButton演示 [

I think you did not read documentation of ConfirmButton. Check samples from ASP.Net and don''t forget to read ConfirmOnFormSubmit Property.

ConfirmButton Demonstration[^]

still facing problem after read this check below code

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
    <asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" />
     <asp:ConfirmButtonExtender ID="cbe" runat="server"

    TargetControlID="Button1"

    ConfirmText="Are you sure you want to click this?"

    ConfirmOnFormSubmit="false"

     />
    <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server"

        ControlToValidate="TextBox1" ErrorMessage="RequiredFieldValidator">
    </asp:RequiredFieldValidator>

当您使用ajax ConfirmButtonExtender时，将在确认消息之后对页面进行验证. 为了避免这种情况，您必须使用Java脚本向用户确认...
有点像这样...

when you use ajax ConfirmButtonExtender your validations of page will be done after the Confirmation Message....
to avoid this you have to confirm from user using Javascript...
somewhat like this...

function checkBeforeConfirm()//put this javascript function
{
    if(Page_ClientValidate()==true)//method to check validations
    {
         if(confirm(''Are You Sure with the Details?'')==true)//confirm after validations check
         {
              return true;
         }
         else
         {
              return false;
         }
    }
    else
    {
         return false;
    }
}

如果您已将验证分为几组，则

if you have divided your validations into groups then

function checkBeforeConfirm()//put this javascript function
{
    if(Page_ClientValidate(''validationGroup'')==true)//method to check validations
    {
         if(confirm(''Are You Sure with the Details?'')==true)//confirm after validations check
         {
              return true;
         }
         else
         {
              return false;
         }
    }
    else
    {
         return false;
    }
}

在Button的"OnClientClick"属性上调用此功能..

on your "OnClientClick" Property of your Button call this funtion..

<asp:button id=".." ...="" onclientclick="return checkBeforeConfirm();" xmlns:asp="#unknown"></asp:button>

这可以从此获得帮助
