XMLファイルをツリービューコントロールに追加するXMLファイルエディタを構築しようとしています。ノードと属性に基づいて、編集可能なテキストボックスやその他のコントロールを表示する必要があります。私はこのXMLデータをシリアル化してデシリアライズして、別のモジュールで処理します。XMLファイルをWPFにバインドするTreeview
私はこれに従うことを試みていますStackoverflow questionしかし、私はそれを動作させることはできません、何もコントロールにバインドします。私はXAMLとMVVMについてかなり新しいです。ので、任意のヘルプは、提案は本当に感謝されます。
PS：[兼ね備え]入力は、XMLファイルですので、あなたの提案に基づいて、私はMVVMを通じてクラスをツリービューまたはserialzedするXMLを直接結合するために開いています。
