C# 勾选方框时要求确认

我目前有一个表单，它有几个复选框，一旦所有的复选框都被选中或保留为空，它就会将复选框的状态发送到数据库 我想补充一点，如果一个框没有被选中，当你选中它时，它应该要求确认窗口“你确定你想选中这个” 需要帮忙吗

这是当前代码

            public IMeditor(IMui IMui, IMuser U, string User)
    {
        InitializeComponent();
        this.IMui = IMui;
        imu = U;
        if (imu.UID == 0)
        {
            Add.Text = "Add";
            imu.name = user;
        }
        else
            Add.Text = "Update";
        AuthChat.Checked = imu.AuthChat == 1;
        AuthTac1.Checked = imu.AuthTac1 == 1;
        AuthTac2.Checked = imu.AuthTac2 == 1;
        AuthTac3.Checked = imu.AuthTac3 == 1;
        AuthTac4.Checked = imu.AuthTac4 == 1;
        AuthTac5.Checked = imu.AuthTac5 == 1;
        AuthTac6.Checked = imu.AuthTac6 == 1;
        AuthTac7.Checked = imu.AuthTac7 == 1;
        AuthTac8.Checked = imu.AuthTac8 == 1;
        AuthTac9.Checked = imu.AuthTac9 == 1;
        AuthTac10.Checked = imu.AuthTac10 == 1;

        switch (imu.Transport.ToLower()) {
            case "aim":   Transport.SelectedIndex = 0; break;
            case "gtalk": Transport.SelectedIndex = 1; break;
            case "msn":   Transport.SelectedIndex = 2; break;
            case "yahoo": Transport.SelectedIndex = 3; break;
        }
    }

您需要为复选框处理事件CheckedChangedEvent。您可以在上找到示例代码。也

理解复选框

或者，您可以从windows窗体的复选框控件派生您自己的类，然后重写所需的函数，实现您自己的逻辑，并从该派生类创建应用程序中的所有复选框。我同意Izzy。添加如下内容

    private void PrivateInitialize()
    {

        CheckBox chkBox = new CheckBox();
        chkBox.Text = "Click me";
        chkBox.CheckedChanged += new EventHandler(chkBox_CheckedChanged);
    }

    private void chkBox_CheckedChanged(object sender, EventArgs e)
    {
        MessageBox.Show("Nag, nag, nag!  You take out the trash yet?");
    }

用javascript实现吗？add OnClientClick=“return confirmCheck（this）；”

功能确认检查（e）{
返回确认（“您确定吗？”）；
//做其他事情
}

这应该比重定向用户要好

你确定要这么骚扰你的用户吗？通常，点击一个框只是勾选或取消勾选框——这正是用户要求的。@sarnold这不是用户填写的表单，这是一个表单，我想提醒用户，他勾选了一个通常不应该勾选的框（只有少数几个框）（仅限管理员）。对不起，我是一个新手的孩子，所以我需要更多的帮助来完成这项工作，也许有人可以编辑我正在使用的代码？或者一步一步地告诉我我要做的事这是winforms应用程序。javascript从何而来？它现在提醒我，如果我愿意将它作为“是”或“否”框，该怎么办？因此，它会询问您是否确实要选中此框，并且只有在选中此框时才会发出提示。。如果取消检查，那么我不喜欢一个消息窗口。我已经发布了新的答案。希望对你有帮助。
