动态创建datetimepicker [英] create datetimepicker dynamically

问题描述

我想获得一天的工作时间
我正在使用一个datetimepicker来获取输入时间，并使用一个datetimepicker来获取退出时间.
使用这些时间，我可以通过公式退出时间-进入时间来计算总时数
我想要以下格式

entryTime:timePicker;退出时间:时间选择器；一天中的小时:退出条目 +


当我在运行时单击此+按钮时，其他行应显示为

entryTime:timePicker;退出时间:时间选择器；一天中的小时:退出条目 +
entryTime:timePicker;退出时间:时间选择器；一天中的小时:退出条目 +

等等
如何动态添加时间选择器的这一行

I want to get working hours of day
i m using one datetimepicker for taking entry time and one datetimepicker for taking exit time.
using these times i calculate total hours by formula Exit time-Entry time
i want following format

entryTime : timePicker ; exit time : Timepicker; hours of day:exit-entry +


when i click this + button at run time other row should appear as

entryTime : timePicker ; exit time : Timepicker; hours of day:exit-entry +
entryTime : timePicker ; exit time : Timepicker; hours of day:exit-entry +

so on
how to add this row that is timepickers dynamically

推荐答案

c#的按钮单击事件，请执行以下操作

On button click event for c# , do the following

private void button1_Click(object sender, EventArgs e)
{
    DateTimePicker dtp = new DateTimePicker();
    //add the new datetimepicker below the previous one
    dtp.Location = new Point(dateTimePicker1.Location.X, dateTimePicker1.Location.Y+25);
    Button btn = new Button(); // add a new button
    btn.Size = button1.Size; //set button size
    btn.Text = "+"; // set button text
    btn.Location = new Point(button1.Location.X, button1.Location.Y+25);
    this.Controls.Add(dtp);
    this.Controls.Add(btn);
}

如果愿意，您可以在表单中添加更多类似的控件，对吗?
