GridView导出Excel实现原理与代码

复制代码 代码如下:

private void DumpExcel(GridView gv, string FileName)
{//带格式导出
string style = @"<style> .text { mso-number-format:/@; } </style>";
Response.ClearContent();
Response.Charset = "GB2312";
Response.ContentEncoding = System.Text.Encoding.UTF8;
Response.AddHeader("content-disposition", "attachment; filename=" + HttpUtility.UrlEncode(FileName, Encoding.UTF8).ToString());
Response.ContentType = "application/excel";
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
gv.RenderControl(htw);
// Style is added dynamically
Response.Write(style);
Response.Write(sw.ToString());
Response.End();
}
public override void VerifyRenderingInServerForm(Control control)
{
}

复制代码 代码如下:

1protected void gvUsers_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
e.Row.Cells[1].Attributes.Add("class", "text");
}
}
