hi,
i m making a project and is having problem in searching from the database. I m searching on the basis of "name" which is a 'combobox' and there are two 'textboxes' for color and price and one 'numericupdown' for quantity which is to be retrieved from database.
So please tell me how to write code in try().

regards
sakshi

Please provide some information about how you're trying to access the database.

We can't be explicit, because we have no idea how your system works, but this is the general idea:
C#
using (SqlConnection con = new SqlConnection(strConnect))
    {
    con.Open();
    using (SqlCommand cmd = new SqlCommand("SELECT iD, description FROM myTable WHERE Name LIKE '%' + @NM + '%'", con))
        {
        cmd.Parameters.AddWithValue("@NM", myNameTextBox.Text);
        using (SqlDataReader reader = cmd.ExecuteReader())
            {
            while (reader.Read())
                {
                int id = (int) reader["iD"];
                string desc = (string) reader["description"];
                Console.WriteLine("ID: {0}\n    {1}", iD, desc);
                }
            }
        }
    }
Clearly, you will need to modify the WHERE clause to fit your circumstances at the minimum.
