定義

命名空間:

System.Windows.Forms

組件:

System.Windows.Forms.dll

取得或設定值，指出是否使用微調按鈕控制項 (也稱為上下按鈕控制項) 來調整日期/時間值。

public:
 property bool ShowUpDown { bool get(); void set(bool value); };

public bool ShowUpDown { get; set; }

member this.ShowUpDown : bool with get, set

Public Property ShowUpDown As Boolean

屬性值

Boolean

如果使用微調按鈕控制項來調整日期/時間值則為 true，否則為 false。 預設為 false。

範例

下列程式碼範例會建立 控制項的新實例 DateTimePicker ，並將其初始化。 控制項的 CustomFormat 屬性已設定。 此外，也會 ShowCheckBox 設定 屬性，讓控制項顯示 CheckBox ，並 ShowUpDown 設定 屬性，讓控制項顯示為微調按鈕控制項。

public:
   void CreateMyDateTimePicker()
   {
      // Create a new DateTimePicker control and initialize it.
      DateTimePicker^ dateTimePicker1 = gcnew DateTimePicker;
      
      // Set the MinDate and MaxDate.
      dateTimePicker1->MinDate = DateTime(1985,6,20);
      dateTimePicker1->MaxDate = DateTime::Today;
      
      // Set the CustomFormat string.
      dateTimePicker1->CustomFormat = "MMMM dd, yyyy - dddd";
      dateTimePicker1->Format = DateTimePickerFormat::Custom;
      
      // Show the CheckBox and display the control as an up-down control.
      dateTimePicker1->ShowCheckBox = true;
      dateTimePicker1->ShowUpDown = true;
   }

public void CreateMyDateTimePicker()
{
   // Create a new DateTimePicker control and initialize it.
   DateTimePicker dateTimePicker1 = new DateTimePicker();

   // Set the MinDate and MaxDate.
   dateTimePicker1.MinDate = new DateTime(1985, 6, 20);
   dateTimePicker1.MaxDate = DateTime.Today;

   // Set the CustomFormat string.
   dateTimePicker1.CustomFormat = "MMMM dd, yyyy - dddd";
   dateTimePicker1.Format = DateTimePickerFormat.Custom;

   // Show the CheckBox and display the control as an up-down control.
   dateTimePicker1.ShowCheckBox = true;
   dateTimePicker1.ShowUpDown = true;
}

Public Sub CreateMyDateTimePicker()
    ' Create a new DateTimePicker control and initialize it.
    Dim dateTimePicker1 As New DateTimePicker()
    
    ' Set the MinDate and MaxDate.
    dateTimePicker1.MinDate = New DateTime(1985, 6, 20)
    dateTimePicker1.MaxDate = DateTime.Today
    
    ' Set the CustomFormat string.
    dateTimePicker1.CustomFormat = "MMMM dd, yyyy - dddd"
    dateTimePicker1.Format = DateTimePickerFormat.Custom
    
    ' Show the CheckBox and display the control as an up-down control.
    dateTimePicker1.ShowCheckBox = True
    dateTimePicker1.ShowUpDown = True
End Sub

備註

ShowUpDown當 屬性設定為 true 時，會使用微調按鈕控制項 (也稱為上下按鈕控制項) ，而不是下拉式行事歷來調整時間值。 您可以個別選取每個元素，並使用向上和向下按鈕來變更值，來調整日期和時間。

若要只在 中 DateTimePicker 顯示時間，請將 Format 屬性設定為 Time ，並將 ShowUpDown 屬性設定為 true 。
