リボンをWebパーツに関連付けています。1つのページに3つ以上のWebパーツを追加する必要があります。
Webパーツごとに個別のコンテキストグループ/タブを作成したくありません。ページの現在のリボンに特定のグループ/タブが存在するかどうかを確認する方法はありますか?
この時点で、ページに複数のWebパーツを追加すると、次のエラーが発生します。
Item has already been added. Key in dictionary: 'Ribbon.MyContextualTabGroup' Key being added: 'Ribbon.MyContextualTabGroup'
参考までに私のコードは次のとおりです。
