このエラーを回避する方法やその意味を知っている人はいますか?
エラー: Microsoft.Reporting.WinForms.LocalProcessingException
内部例外: Microsoft.ReportingServices.ReportProcessing.ProcessingAbortedException
(以下のコード スニペットの catch ブロック内にコメントとして完全なエラーを入れます)
VS 2010 内でローカル レポート/レポート ビューアーを実行するのはこれが初めての試みですが、このレンダリング メソッドは毎回爆発的に増加しており、Google はあまり役に立たないようです。
明らかな間違いを見つけることができますか?
参考までに、表示されていないものは、データセットとして使用されるコードに入力される 1 つのデータテーブルと、1 つのテーブルを持ち、1 つのデータセットだけを持つデータソースを使用する 1 つの rdlc ファイル (レポート) を持つ非常に単純な XSD です。 (xsd)。
ありがとう。
