一日一步 之将GrideView导出为Excel表格

使用控件的RenderControl（）方法导出Excel .

//使用控件的RenderControl（）方法生成HTML表格

string strName = "HuaMingCe";

Response.Clear();

Response.Buffer = true;

Response.Charset = "utf-8";

Response.AppendHeader("Content-Disposition", "attachment;filename=" + strName + ".xls");

Response.ContentEncoding = System.Text.Encoding.GetEncoding("utf-8");//设置输出流为简体中文

Response.ContentType = "application/ms-excel";//设置输出文件类型为excel文件。

this.EnableViewState = false;

System.Globalization.CultureInfo myCItrad = new System.Globalization.CultureInfo("ZH-CN", true);

System.IO.StringWriter oStringWriter = new System.IO.StringWriter(myCItrad);

System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);

if (GridViewMaster != null) //GridViewMaster 是GridView控件

{

GridViewMaster.RenderControl(oHtmlTextWriter);//将服务器控件的内容输出

}

Response.Write(oStringWriter.ToString());

Response.End();

//同时vs2005会报错“类型“ExGridView”的控件“GridViewMaster”必须放在具有 runat=server 的窗体标记内

”

//需要添加下面取消对GridViewMaster 控件验证的方法

public override void VerifyRenderingInServerForm(Control control)

{

if (!control.GetType().Equals(GridViewMaster.GetType()))

{

base.VerifyRenderingInServerForm(control);

}

}
