Hi!
I have a serious problem; when I run my page its works but after inserting name on my "textbox" and click on my "button" there is a bug on this code: con.Open();
The error message is:
"login failed for user, the user is not associated with a trusted Sql server connection";
My codes:
using System;
using System.Data;
using System.Configuration;
using System.Data.SqlClient;
public partial class _Default : System.Web.UI.Page
{
public SqlConnection con;
public string constr;
public void connection()
{
constr=ConfigurationManager.ConnectionStrings["master"].ToString();
con = new SqlConnection(constr);
con.Open();
}
protected void Page_Load(object sender, EventArgs e)
{
//Label1.Visible = false;
}
private void rep_bind()
{
connection();
string query = "select * from company where Name like'" + TextBox1.Text + "%'";
SqlDataAdapter da = new SqlDataAdapter(query, con);
DataSet ds = new DataSet();
da.Fill(ds);
GridView1.DataSource = ds;
GridView1.DataBind();
}
protected void Button1_Click(object sender, EventArgs e)
{
connection();
string query = "select Name from company where Name like'" + TextBox1.Text + "%'";
SqlCommand com = new SqlCommand(query, con);
SqlDataReader dr;
dr = com.ExecuteReader();
if (dr.HasRows)
{
dr.Read();
rep_bind();
GridView1.Visible = true;
TextBox1.Text = "";
Label1.Text = "";
}
else
{
GridView1.Visible = false;
Label1.Visible = true;
Label1.Text = "The search Term " + TextBox1.Text + " Is Not Available in the Records";
}
}
}
