Question

I have 4 list boxes and I have a DB as EMP with table tab1 and columns Name,EmpId, Salary …

So I want to display salary in one of the list boxes. How do I do it???

SqlConnection con = new SqlConnection(connec);
string insert_query = "select Salary from tab1";
con.Open();
try
{
    SqlCommand cmd = new SqlCommand(insert_query, con);
    int exe = cmd.ExecuteNonQuery();
    SqlDataAdapter da = new SqlDataAdapter(cmd);
    DataSet ds = new DataSet();
    da.Fill(ds);
    ListBox3.DataSource = ds;
    ListBox3.DataBind();
 }

Is this the way? I have some problems like the items are not been displayed in the list boxes.

Answer 1

ListBox3.DataSource = ds;
ListBox3.DataTextField = "Salary";
ListBox3.DataValueField = "EmpID";
ListBox3.DataBind();

you need to specify this before.
