FrozenCells

FlexGrid のセル固定機能を使用すると、ユーザーは特定の行と列を固定し、グリッドの他の部分をスクロールしている間もそれらの行と列を表示したままにすることができます。

5.20241.19以前バージョンのFlexGridでは FrozenRowsプロパティ と FrozenColumns プロパティを使用して、左側と上部のセルを固定することをサポートしていました。

この機能は 5.20242.21のバージョンで強化され、新たに追加されたFrozenCells プロパティを利用することで、右側と下部のセルを固定するオプションが追加されました。

サポートされている操作

  1. 左または右の列を固定することができます。
  2. 上部または下部の行を固定することができます。
  3. 水平方向(左または右)と垂直方向(上または下)を1つずつ組み合わせて、固定することができます。

重要: FrozenCellsプロパティでは 4 つの側面すべてにオプションを提供しますが、同時にセルをフリーズできるのは2つの側面のみです。

  • 片方の水平方向(左または右)
  • 1 つの垂直面 (上部または下部)

注意:

  • 左と右の両方が設定されている場合は、左が有効になります。
  • 同様に、上と下の両方がある場合は、上が適用されます。
