在button_click事件中写入以下代码。

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. 

你将不得不重写VerifyRenderingInServerForm的功能一样，你必须设置我们使用hipdf库

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

财产这个

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