DoSpinDown(TimeSpan) メソッド

スピン機能を使ってタイムスパンコントロールの値を減少します。

構文

Visual Basic (宣言)
C#

Public Overloads Sub DoSpinDown( _
   ByVal increment As TimeSpan _
)

public void DoSpinDown( 
   TimeSpan increment
)

パラメータ

increment: 値の減少量を表すTimeSpan値。

解説

このメソッドは、このコントロールの値をincrementパラメーターに従ってスピンダウンします。

使用例

サイドボタンと入力フィールドを設定した GcTimeSpan コントロールを作成するコード例を次に示します。サイドボタンクリック時にコントロールの値が変化します。この例では他に SideButtons、 Fields プロパティと DoSpinUp(TimeSpan) や DoSpinDown メソッドを使用しています。

C#
Visual Basic

//  Please use the following namespace
//  using System.Windows.Forms;
//  using GrapeCity.Win.Editors;
//  using GrapeCity.Win.Editors.Fields;

// Creates an instance of a GcTimeSpan control.
GcTimeSpan gcTimeSpan1 = new GcTimeSpan();
public void InitializeGcTimeSpan()
{
    // Sets the Fields settings.
    gcTimeSpan1.Fields.Clear();
    gcTimeSpan1.Fields.AddRange(@"hh:mm:ss",2,'.',string.Empty,string.Empty,"-",string.Empty);

    // Defines SymbolButtons.
    SymbolButton symbolButton1 = new GrapeCity.Win.Editors.SymbolButton();
    SymbolButton symbolButton2 = new GrapeCity.Win.Editors.SymbolButton();
    symbolButton1.Name = "symbolButton1";

    symbolButton1,
    symbolButton2});
}

    // Spin the GcTimeSpan value to the less one.
    gcTimeSpan1.DoSpinDown(new TimeSpan(1, 0, 0, 0));
}

private void OnSymbolButton1Click(object sender, EventArgs e)
{
    // Spin the GcTimeSpan value to the greater one.
    gcTimeSpan1.DoSpinUp(new TimeSpan(1, 0, 0, 0));
}
