Question

我正在尝试在pdf中导出几个gridviews，但它们不会在HtmlTextWriter中呈现 gridview是动态创建的，嵌套在转发器控件中。作为数据源，我使用数据表，尽管表格显示在浏览器中（连同它们的数据），但它们不会以pdf文件呈现。

代码下方谢谢！

ASPX：

我不确定嵌套网格视图，但是要将gridview导出为pdf，您必须从Internet下载itextsharp.dll并将其放在项目的bin文件夹中。

有一个示例输出如何将gridview导出为pdf。你可以在这里参考。

export-gridview-to-pdf

希望它有所帮助。

转发器中的嵌套gridview未以pdf格式导出
