以下是一个页面的代码：
namespace WebApplication1
{
public partial class dingdan : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
string strcnn = ConfigurationManager.ConnectionStrings["s"].ConnectionString;
SqlConnection cnn = new SqlConnection(strcnn);
SqlCommand cmd = new SqlCommand();
cmd.Connection = cnn;
cmd.CommandText = "delete from [order] where uid='" + DropDownList1.SelectedValue.Trim() + "' and pid in (select id from sp where name='" + GridView1.SelectedRow.Cells[1].Text.Trim() + "')";
try
{
cnn.Open();
cmd.ExecuteNonQuery();
Response.AddHeader("Refresh", "0");
}
catch (Exception ex)
{
}
finally
{
if (cnn.State == ConnectionState.Open)
cnn.Close();
}
}
protected void Button2_Click(object sender, EventArgs e)
{
Response.Redirect("~/login.aspx");
}
protected void Button3_Click(object sender, EventArgs e)
{
Response.Redirect("~/editsp.aspx");
}
protected void SqlDataSource1_Selecting(object sender, SqlDataSourceSelectingEventArgs e)
{
}
protected void SqlDataSource2_Selecting(object sender, SqlDataSourceSelectingEventArgs e)
{
}
}
}
VS上的界面可以显示，但是调式出来在网页上看不见，求助！
最好是能够写出代码，告诉我怎么做，谢谢！！
