DoSpinUp(Decimal) メソッド

スピン機能を使って値を増加します。

構文

Visual Basic (宣言)
C#

Public Overloads Sub DoSpinUp( _
   ByVal increment As Decimal _
)

public void DoSpinUp( 
   decimal increment
)

パラメータ

increment: 値の増加量を表すDecimal値。

解説

このメソッドの動作は、［↑］キーを押したときの動作と同じです。

使用例

サイドボタンと入力フィールドを設定した GcNumber 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 や DoSpinDown(Decimal) 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 GcNumber control.
GcNumber gcNumber1 = new GcNumber();
public void InitializeGcNumber()
{
    // Sets the Felds property.
    gcNumber1.Fields.DecimalPart.MaxDigits = 2;
    gcNumber1.Fields.DecimalPart.MinDigits = 2;
    gcNumber1.Fields.IntegerPart.GroupSizes = new int[] {3,3,0};
    gcNumber1.Fields.IntegerPart.MaxDigits = 9;
    gcNumber1.Fields.IntegerPart.MinDigits = 1;

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

    symbolButton2.Click += new EventHandler(OnSymbolButton2Click);

    // Adds SymbolButtons to the SideButtons collection.
    gcNumber1.SideButtons.AddRange(new GrapeCity.Win.Editors.SideButtonBase[] {
    symbolButton1,
    symbolButton2});
}

private void OnSymbolButton2Click(object sender, EventArgs e)
{
    // Spin the GcNumber value to the less one.
    gcNumber1.DoSpinDown(1m);
}

private void OnSymbolButton1Click(object sender, EventArgs e)
{
    // Spin the GcNumber value to the greater one.
    gcNumber1.DoSpinUp(1m);
}
