Question

how can I get the selected item’s value of a list box?

I tried something like this:

            foreach (var item in combo_course_op.SelectedItems)
            {
                string s = "select cid from tms_course where course_title = '" + item.ToString() + "'";
            }

but it doesnt works..it shows string s as “select cid from tms_course where course_title =’System.Data.DataRowView'”

where am I doing wrong?

This is how I data binded:

MyCommand = new OdbcCommand("select distinct module_name from tms_class_schedule where class_date ='"+selectedDate+"'", DBConnect.MyConnection);
            dap = new OdbcDataAdapter(MyCommand);
            DS = new DataSet();
            dap.SelectCommand = MyCommand;
            dap.Fill(DS);
            combo_course_op.DataContext = DS.Tables[0].DefaultView;
            combo_course_op.DisplayMemberPath = DS.Tables[0].Columns["module_name"].ToString();

Answer 1

foreach (var item in combo_course_op.SelectedItems)
{
    string s = "select cid from tms_course where course_title = '" 
             + (item["Title"] as string) + "'"; // if Title is column name. Otherwise replace "Title" with actual column header name
}
