PowerTools MultiRow for Windows Forms 8.0J
CheckAlign プロパティ (CheckBoxCell)
使用例 

CheckBoxCell上でのチェックマークの水平および垂直方向の配置を取得または設定します。
構文
Public Property CheckAlign As ContentAlignment
public ContentAlignment CheckAlign {get; set;}

プロパティ値

System.Drawing.ContentAlignment値の1つ。既定値はSystem.Drawing.ContentAlignment.MiddleLeftです。
例外
例外解説
System.ComponentModel.InvalidEnumArgumentException指定された値がSystem.Drawing.ContentAlignment値の1つではありません。
解説
このプロパティの値をSystem.Drawing.ContentAlignment.MiddleCenterにすると、チェックボタンがテキストの上に重なる場合があります。
使用例
次のサンプルコードは、CheckBoxCellが持ついくつかの重要なプロパティを示します。ここでは、ThreeStatetrueに設定し、各状態の格納値をTrueValueFalseValue、およびIndeterminateValueによって設定しています。さらに、TextCheckAlignを変更しています。
