asp.net实现Gradview绑定数据库数据并导出Excel的方法
本文实例讲述了asp.net实现Gradview绑定数据库数据并导出Excel的方法。分享给大家供大家参考，具体如下：
protected void showData_Click(object sender, EventArgs e)
{
SqlConnection myConnection
= new SqlConnection("Data Source=localhost;Initial Catalog=test;User ID=sa;password=sa");
SqlDataAdapter ad = new SqlDataAdapter("SELECT * FROM booklist", myConnection);
DataSet ds = new DataSet();
ad.Fill(ds);
this.gvShowData.DataSource = ds;
this.gvShowData.DataBind();
}
//导出Excel表
protected void btnExportToExcel_Click(object sender, EventArgs e)
{
Response.Charset = "GB2312";
Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");
Response.AddHeader("Content-Type", "application/vnd.ms-excel");
Response.AddHeader("Content-Disposition", "myexcelfile.xls");
//以此编码模式导出才不会出现乱码
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
gvShowData.RenderControl(htw);
Response.Write(sw.ToString());
Response.End();
}
//一定要写，否则出错！！
public override void VerifyRenderingInServerForm(Control control)
{
}
希望本文所述对大家asp.net程序设计有所帮助。
