HotSpotMode プロパティ (FpChart)

System.Web.UI.WebControls.HotSpotオブジェクトがクリックされたときの、FpChartコントロールのSystem.Web.UI.WebControls.HotSpotオブジェクトのデフォルト動作を取得または設定します。

構文

Visual Basic
C#

'Declaration
 
Public Overridable Property HotSpotMode As HotSpotMode

public virtual HotSpotMode HotSpotMode {get; set;}

プロパティ値

System.Web.UI.WebControls.HotSpotMode列挙値の1つ。デフォルト値はNotSetです。

解説

このプロパティは、RenderMapAreaプロパティがtrueのときに有効となり、ユーザーがチャートのマップエリアをクリックしたときの動作を決定します。設定値は、Inactive、Navigate、およびPostBackです。Inactiveは、チャートのマップエリアにツールチップを表示する場合に便利です。

ユーザーがチャートの要素をクリックしたときにMapAreaClickイベントを発生させることができます。それには、RenderMapAreaプロパティをtrueに設定し、このプロパティをPostBackに設定する必要があります。

例

次のサンプルコードは、Spreadにチャートコントロールを作成していくつかのイベントをマップします。
