C# iTextSharp aspx到pdf，服务器。执行错误

在ASP.net中，我制作了一个用于填写报价表的网页。 有三个分区。左侧的div中有要填写的文本框。 作为形式本身的中间部门。 右边有按钮的div

到目前为止，我只能将midlesector导出为PDF格式，并在左侧和所有位置填写内容。问题是它完全忽略了CSS，而CSS是使用绝对定位制作的。因此，我想问一下如何包含CSS样式，使它看起来像它应该的样子，而不是一个连续的文本

这是middlesector的代码：

最后是代码隐藏函数：（编辑：10-10-2013:14:22:GTM+1）

我在以下位置得到一个错误： 执行（“中间扇区”，strWriter）； 对于以下情况，也存在相同的错误： Server.Execute（“OfferteForm1.aspx”，strWriter）

它与IUSRS_machinename和ASPNET用户的权限有关。 但我不知道如何添加权限，因为我没有清单，也无法创建清单

我也试过： HtmlDecode（“中间扇区”，strWriter）； 以及： HtmlDecode（“OfferteForm1.aspx”，strWriter）

它确实编译了一个PDF，但它只有图像。

我只希望XMLWorker在middlesector Div中包含填写的表单。

您使用的是

HTMLWorker

，而该类不查看CSS。尝试使用XML Worker：问题是我使用的是旧版本的iTextSharp，因为它有不同的许可协议。正如@BrunoLowagie所说，

HTMLWorker

不支持CSS，因此除非您想编写自己的解析器，否则没有解决方案。官方解决方案是使用

XMLWorker

。此外，关于4.x（2.1.7）版本是“免费”的说法还有很多，你可能想了解更多。我现在正在使用“XMLWorker”，但在使用它时遇到了一些问题。我只想把一个div及其内容放在PDF中，但我找不到一个这样做的例子。它使用这个.div.RenderControl（“TextWriter”）与HTMLWorker一起工作，但显然它忽略了CSS。有人知道怎么做吗？
