C＃如何找出动态创建的不确定数量的复选框的任何检查状态更改

Posted 2021-05-06

虚伪地说，我有一份工作正在为我的客户创造想法。对于一个客户端，我有一个建议列表，我从中创建了相应的复选框。现在我需要知道哪些客户端未经检查，所以我可以删除它们。

- 建议数量不固定。该数字是我当前SuggestionList的长度。

int checkboxnumber = Myclass.suggestionline.Count();

for (int i = 0; i < checkboxnumber; i++)
{
    CheckBox cb = new CheckBox();
    cb.Text = Myclass.suggestionline[i][0];
    cb.Location = new Point(5, 5 + i * 24);
    cb.BackColor = Color.White;
    cb.Name = "checkbox"+i;
    cb.AutoSize = true;
    cb.Checked = true;
    panel1.Controls.Add(cb);
};

我将SuggestionList构建为List <List <string >>，4个建议SuggestionList示例如下：

{{"suggestion1", "like", "100 Euro"},{"suggestion2", "like", "200 Euro"},{"suggestion3", "like", "300 Euro"},{"suggestion4", "like", "400 Euro"}}

答案

我想到了。感谢这个相关的问题：How can I create a dynamic button click event on a dynamic button?

CheckBox cb = new CheckBox();

...

int checkboxnumber = Myclass.suggestionline.Count();

        for (int i = 0; i < checkboxnumber; i++)
        {
            cb = new CheckBox();
            cb.Text = Myclass.suggestionline[i][0];
            cb.Location = new Point(5, 5 + i * 24);
            cb.BackColor = Color.White;
            cb.Name = "checkbox"+i;
            cb.AutoSize = true;
            cb.Checked = true;
            cb.CheckedChanged += new EventHandler(CheckedChanged);
            panel1.Controls.Add(cb);
        };

...

private void CheckedChanged(object sender, EventArgs e)
        {
            CheckBox cb = sender as CheckBox;
            if (!cb.Checked)
            {
                Console.WriteLine(cb.Text);

            }
        }
