如何在c文本框的焦點上設置datapicker＃

Question

如何在c sharp .net的窗體應用程序中設置datatimepicker。當我關注日期文本框時，我的datetimepicker控件顯示出來，並在該日期點擊該特定日期後，在文本框中顯示myformatted輸出。我使用簡單的datetimepicker控件。

我只使用C＃.NET

Answer 1

你可以只使用ValueChanged事件在dateTimePicker要做到這一點很容易的窗口形式的應用DateTimePicker控件。

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：

將這種形式負載：

//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); 

然後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. 
} 

Answer 3

 // 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(); 
     }
