本文介绍在查询无数据时如何在GridView中显示头部信息，通过创建空数据集并将其作为数据源来实现。

Show of Gridview Header with Empty Data Source

This is the method for showing the Header of GridView when no data returned in the query.

DataTable dt = new DataTable();
_conn = new DbConnection();
dt = _conn.ExecuteSelectQueryNoParam("select * from test");
if (dt.Rows.Count == 0)
{               
    DataRow dr = dt.NewRow();
    dt.Rows.Add(dr);
}
GridView1.DataSource = dt;
GridView1.DataBind();
GridView1.Rows[0].Visible = false;
