推荐答案

在下拉列表的selectedindex更改事件中，查询数据库并将值填充到数据表中并将其绑定到gridview

In the selectedindex change event of dropdown query the database and fill the values in to datatable and bind it to gridview

SqlDataAdapter da = new SqlDataAdapter("select * from students where name='" + DropDownList1.SelectedItem.Text + "'", con);
       DataTable dt = new DataTable();
       da.Fill(dt);
       GridView1.DataSource = dt;
       GridView1.DataBind();
