问题描述

先生，这是查看页面吗？

string constr = ConfigurationManager.ConnectionStrings [CONSTR]。ConnectionString;

private int id = 0;



protected void Page_Load（object sender，EventArgs e）

{

id = Convert.ToInt32（Request.QueryString [ id]。ToString（））;

if（！IsPostBack）

{

BindControlvalues（）;

}



}



private void BindControlvalues（）

{

SqlConnection con = new SqlConnection（constr）;

con.Open（）;

SqlCommand cmd = new SqlCommand（select * from tbl_addnewproduct where id =+ id，con）;

SqlDataAdapter da = new SqlDataAdapter（cmd）;

cmd.ExecuteNonQuery（）;

con。关闭（）;

Dat aSet ds = new DataSet（）;

da.Fill（ds）;

Image1.ImageUrl = ds.Tables [0] .Rows [0] [1]。 ToString（）;

Label1.Text = ds.Tables [0] .Rows [0] [2] .ToString（）;

Label2.Text = ds.Tables [0] .Rows [0] [3] .ToString（）;



}
