Answer 1

我们正在使用hipdf库，但这是付费的，我们首先将html转换为图片，然后在ppt幻灯片上显示此图片。您也可以使用inkscape exe文件

来完成

Answer 2

在button_click事件中编写以下代码。

GridView1.AllowPaging = false; //write this code only if paging is enabled.
GridView1.DataBind(); //write this code only if paging is enabled.

Response.Clear();

Response.AddHeader("content-disposition", "attachment;filename=FileName.ppt");//for text file write FileName.txt

Response.Charset = "";

// If you want the option to open the Excel file without saving than comment out the line below
// Response.Cache.SetCacheability(HttpCacheability.NoCache);

Response.ContentType = "application/vnd.ppt";\\for text file write vnd.txt

System.IO.StringWriter stringWrite = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
GridView1.RenderControl(htmlWrite);

Response.Write(stringWrite.ToString());

Response.End();

GridView1.AllowPaging = true; //write this code only if paging is enabled.

GridView1.DataBind();//write this code only if paging is enabled.

你必须像这样覆盖VerifyRenderingInServerForm的功能

public override void VerifyRenderingInServerForm(Control control)
{
    //Keep it empty
}

为避免异常，您必须设置

的属性

<%@ Page Language="C#" EnableEventValidation="false" %>
