如何在C＃中的文本框焦點中設置數據選擇器

Question

如何在C Sharp .net的窗口形式的應用程序中設置datatimepicker。 當我關注該日期文本框時，將顯示我的datetimepicker控件，然后在該日期中單擊該特定日期后，將其顯示在文本框中顯示在myformatted輸出中。我使用簡單的datetimepicker控件。

我只在c＃.net的窗口窗體應用程序中使用datetimepicker控件

Answer 1

您只需在dateTimePicker使用ValueChanged Event即可輕松做到這一點。

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

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

Answer 2

您可以使用數據綁定：

將其放入表單加載中：

//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b_Format處理程序：

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");
      }

 private void dateTimePickerBillDate_ValueChanged(object sender, EventArgs e)
        {
            DateTime pickdt = Convert.ToDateTime(dateTimePickerBillDate.Text);
            maskedtxtBillDate.Text = pickdt.ToString();
        }
