单击取消时，不应填充该值 [英] on clicking cancel the value shouldn't populate

问题描述

您好，我创建了一个按钮"XX".单击此按钮时，应该会弹出一个对话框，提示您确定要加载数据吗?"，如果是，则应加载..如果我单击取消"不应该填充我数据库中的数据..

Hi i have created a button say"XX"..On clicking this button it should pop up a dialog box saying "Are you sure you wanna load the data?"If yes it should load..if i click cancel it shouldn''t populate the data in my database..

<asp:Button ID="button1" runat="server" align="left" BackColor="#CCCCCC" Font-   Bold="True" Text="XX" OnClick="button1_click"/>

<Ajx1:ConfirmButtonExtender ID="ConfirmButtonExtender1"  runat="server" TargetControlID="button1" ConfirmText="Are you sure you want to load data?"
önClientCancel="cancelClick" Enabled="True" />

我用来填充数据的代码是

And my code to populate the data is

protected void button1_click(object sender, EventArgs e)
      {
          seph x= new seph();

          x.Date = DateTime.Now;
          x.name= Membership.GetUser().UserName;

          dc.sephs .InsertOnSubmit(x);
          dc.SubmitChanges();
       }

仅当我单击对话框上的yes时，此代码才应填充数据...并且单击取消时应不填充数据库中的任何数据...但是到目前为止，即使单击取消也可以填充数据.有人告诉您是否需要任何修改?

This code should populate the data only when I click yes on my dialog box...and should not populate any data in my DB when I click cancel...But as of now even when I click cancel its populating the data..Can some one tell whether there is any modification required??

推荐答案

您甚至不需要扩展程序就可以进行修改.一个简单的按钮就可以解决问题.

此处:

You don''t even need an extender to do it. A simple button would do the trick.

Here:

<asp:Button ID="button2" runat="server" align="left" BackColor="#CCCCCC"

            Font-Bold="True" Text="XX"

            onClientClick="if(!confirm('Are you sure you want to delete this entry?')) return false;"

            onclick="button2_Click"/>

现在，如果有人同意，那么server onclick后面的代码将被触发，否则将被触发.

更新:我更新了上面的代码段.确认文本用双引号引起来，需要用单引号引起来.

Now, if person agrees then the code behind server onclick will be triggered or else not.

UPDATE: I updated the snippet above. Confirm text was in double quotes that needs to be in single quotes.

用这个
在page_load事件中，为按钮添加onclick属性:

Hi,

use this,
in page_load event add the onclick attribute for the button:

button1.Attributes.Add("onclick", "return fnConfirm();");

这是您的按钮结构.保持原样.

This is your button structure. Let it be like as it is.

<asp:Button ID="button1" runat="salign="left" BackColor="#CCCCCC" Font-   Bold="True" Text="XX" OnClick="button1_click"/>

编写javascript功能:

write javascript fuction:

function fnConfirm(){
    if(confirm("Are you sure you wanna load the data?")){
        return true;
    }
    return false;
}

这将为您提供帮助.通过此代码，您可以了解流程.
并请从您的代码中删除ConfirmButtonExtender.

祝一切顺利.
