我只在c＃.net

的窗口表单应用程序中使用datetimepicker控件

Answer 1

您可以在ValueChanged中使用dateTimePicker事件轻松完成此操作。

private void dateTimePicker1_ValueChanged(object sender, EventArgs e)
{
   textBox1.Text = YourFormatedMethod(dateTimePicker1.Text);
}

private string YourFormatedMethod(string selectedDate)
{
  // Your implementation
}

Answer 2

您可以使用数据绑定：

将其置于表单加载中：

//textBox1.DataBindings.Add("Text", dateTimePicker1, "Text");
//or...
Binding b = new Binding("Text", dateTimePicker1, "Value",true);
b.Format += new ConvertEventHandler(b_Format);
textBox1.DataBindings.Add(b);

然后是b_Format处理程序：

private void b_Format(object sender, ConvertEventArgs e)
{
    //some checking you might want to do...

    e.Value = //your formatting here.
}

      // date time picker event code
      private void dtpfromdate_ValueChanged(object sender, EventArgs e){
          dtpfromdate.Format = DateTimePickerFormat.Custom;

          //here we can select our desired format.
          dtpfromdate.CustomFormat = "dd-MM-yyyy";
          txtfromdate.Text = dtpfromdate.CustomFormat;

          //assign the datetime picker value to textbox.
          txtfromdate.Text = dtpfromdate.Value.ToString("dd-MM-yyyy");
      }
