如何将日历控件中的日期插入Windows窗体的文本框中 [英] How to insert date from a calendar control into text box for windows forms

问题描述

private void monthCalendar1_DateChanged(object sender, DateRangeEventArgs e)
        {
            monthCalendar1.DateSelected = txtdatein.Text;
           
        }

/*我已经键入此代码，以便接受日历控件"monthCalendar1"中的日期到文本框"txtdatein"的日期，但是会产生错误.我知道asp.net的代码，但不知道ado.net的代码，我希望知道. */

产生的错误是

错误1事件"System.Windows.Forms.MonthCalendar.DateSelected"只能出现在+ =或-=

/* i have typed this code inorder to accept date from my calendar control "monthCalendar1" to my text box "txtdatein" but it generates error. I know the code for asp.net but not for ado.net, which i am expecting to know. */

the error generated is

Error 1 The event ''System.Windows.Forms.MonthCalendar.DateSelected'' can only appear on the left hand side of += or -=

推荐答案

的左侧您要在Windows Forms程序中使用DateTimePicker控件.

dateTimePicker1_ValueChanged.此事件处理程序在DateTimePicker上非常有用.每当用户更改DateTime时，都会执行此事件处理程序.
尝试这种方式:

i think You want to use the DateTimePicker control in your Windows Forms program.

dateTimePicker1_ValueChanged. This event handler is very useful on the DateTimePicker. Whenever the user changes the DateTime, this event handler is executed.
try this way :

private void dateTimePicker1_ValueChanged(object sender, EventArgs e)
    {
        // Set title bar to selected date.
        DateTime result = dateTimePicker1.Value;
        TExtbox1.Text= = result.ToString();
    }

此控件通常使用MonthCalendar.SelectionRange属性显示单个日期，而不显示日期范围.您可以使用MonthCalendar.SelectionRange.Start或MonthCalendar.SelectionStart在文本框中显示此范围的开始.

请参阅:

http://msdn.microsoft.com/en-us/library/system.windows.forms.selectionrange.start.aspx [ ^ ].

您需要使用具有适当格式的System.DateTime.ToString获取时间的字符串表示形式(System.DateTime结构).请参阅:
http://msdn.microsoft.com/en-us/library/system.datetime.aspx [ ^ ]，
http://msdn.microsoft.com/en-us/library/zdtaw1bw.aspx [ ^ ]，

This control generally shows not a single date, but a range of dates, using the property of MonthCalendar.SelectionRange. You can display the start of this range in you text box, using MonthCalendar.SelectionRange.Start or MonthCalendar.SelectionStart.

Please see:
http://msdn.microsoft.com/en-us/library/system.windows.forms.monthcalendar.selectionrange.aspx[^],
http://msdn.microsoft.com/en-us/library/system.windows.forms.selectionrange.start.aspx[^].

You need to get a string representation of the time (System.DateTime structure) using System.DateTime.ToString with appropriate format. Please see:
http://msdn.microsoft.com/en-us/library/system.datetime.aspx[^],
http://msdn.microsoft.com/en-us/library/zdtaw1bw.aspx[^],
http://msdn.microsoft.com/en-us/library/az4se3k1.aspx[^],

Last two links reference the MSDN article on how to use date/time format.

您可以在dateTimePicker1_ValueChanged事件中编写以下代码.

Hi,
You can write the folowing code in dateTimePicker1_ValueChanged event.

textBox1.Text= = dateTimePicker1.Value.ToString();
