在asp.net中禁用CheckBox [英] CheckBox disabled in asp.net

问题描述

我正在尝试在asp.net中发送邮件。管理员发送邮件到相应的电子邮件ID然后管理员检查复选框并发送电子邮件，此后我想显示复选框禁用这是我想要的，因为当管理员再次登录然后他将无法再次检查相同的复选框因为邮件已经发送，当新邮件到来时，必须启用复选框，因为管理员仍然没有在新邮件中执行任何检查......



在我的项目中......我签入复选框，然后单击提交按钮，然后发送电子邮件发送，但当管理员再次登录，然后检查新记录是否来，然后上一个复选框始终启用但我希望在以前的记录中禁用复选框，因为电子邮件已发送..

推荐答案

嗨Ayesha，



对于你的问题，我想提出一个想法。

你需要加一个更多列，例如表中的 IsMailSent int。

如果管理员向该emailid发送电子邮件，则将IsMailSent列更改为 1 否则 0 。

当管理员再次登录时，尝试检查字段，并根据启用/禁用页面中的复选框。

表应该像



emailid isEMailSent

[e-mail] 1

[e-mail] 0

[e-mail] 0



现在加载管理页面检查isEmailSent字段，如果它的0然后启用其他复选框e禁用它。

成功发送邮件后，您可以将值更改为1，以便将电子邮件发送到该特定电子邮件ID。

希望这对您有所帮助。



问候，

RK

Hi Ayesha,

For your problem, I would like to suggest one idea.
You need to add one more column like "IsMailSent" int in your table.
If admin sends an email to that emailid then change IsMailSent column to 1 otherwise 0.
And when admin logins again try to check the field and according to that enable/disable the checkbox in your page.
Table should be like

emailid isEMailSent
[e-mail] 1
[e-mail] 0
[e-mail] 0

now while loading admin page check for isEmailSent field and if its 0 then enable the checkbox otherwise disable it.
After sending mail successfully you can change the value to 1 to mention that email is sent to that particular email id.
Hope this helps you a bit.

Regards,
RK

我会通过javascript设置a控制已选中/未选中状态boolean true / false基于你在构建页面时发生的事情（在发送之后），当你收到一条消息时你把它恢复为真。



否则你需要收到电子邮件时的回发。

I would control the checked/unchecked state through javascript set a boolean true/false based on what happens when you build the page (after sent eg) when receiving a message you put it back to true.

Otherwise you'll need a postback when an email is received.
