WPF Toolkit DataGrid と .NET 3.5 を約 2 年間使用しています。また、「Automation Peer API への再帰呼び出しが無効です」という例外をスローする 2 つのケースがあります。それは非常に奇妙で不安定です。このような問題が発生する PC はほとんどありません。
ケース 1:
ドロップダウン コンボックス (DropDown コンテンツ コントロールとしての WPF Tookit DataGrid):
そして、それは次の方法で解決できます。
protected override AutomationPeer OnCreateAutomationPeer()
{
return null;
}
この解決策は、Automation Peer API への WPF 再帰呼び出しが有効ではありません。
ケース 2:
WPF Tookit DataGrid には Temlate Column があり、セル テンプレートにはドロップダウン コンボックス (DropDown コンテンツ コントロールとしての WPF Tookit DataGrid) があります。上記の解決策では修正できません。
