| 在以下按钮单击事件中实现：
private void btnMIME_Click(object sender, System.EventArgs e)
{
dgShow.AllowPaging = false;
BindData();
Response.ContentType = "application/vnd.ms-excel";
Response.AddHeader("Content-Disposition", "inline;filename="
+ HttpUtility.UrlEncode("下载文件.xls",Encoding.UTF8 ) );
//如果输出为Word，修改为以下代码
//Response.ContentType = "application/ms-word"
//Response.AddHeader("Content-Disposition", "inline;filename=test.doc")
StringBuilder sb=new StringBuilder();
System.IO.StringWriter sw = new System.IO.StringWriter(sb);
System.Web.UI.HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter(sw);
sb.Append("<html><body>");
dgShow.RenderControl(hw);
sb.Append("</body></html>");
Response.Write(sb.ToString());
Response.End();
dgShow.AllowPaging = true;
BindData();
}
注：1.若DataGrid中有按钮列，则在导出前应先将其隐藏.
2.若DataGrid有分页，而又要打印所有数据的话就应先取消分页.
若为VS.NET2005中的数据绑定新控件GridView,以上代码会提示异常错误，经网上搜索，解决方案如下:
1、在导出界面中重载
public override void VerifyRenderingInServerForm(Control control)
{
//base.VerifyRenderingInServerForm(control);
}
2、在web.config中修改<pages enableEventValidation ="false" ></pages>
或
<%@ Page Language="C#" EnableEventValidation = "false" AutoEventWireup="true"
CodeFile="ExportGridView.aspx.cs" Inherits="ExportGridView" %>
