Thread: Dynamic Button Text

I have two forms, one form I enter information into that populates a db... on the other, I need to text on the buttons to change based on the information in the 'Description' field. This change should happen when I hit the save button on the other form. Here is my code:

Code:

private void ButtonTextChange()
        {
            SqlConnection conn = new SqlConnection("Data  Source=DAHLENO0744\\;Initial Catalog=USPCNew;Integrated  Security=True;Pooling=False");
            try
            {
                conn.Open();
                int myint = 1;
                string sql = "select a.* from (SELECT ButtonNum, Description FROM StationSetup WHERE ButtonNum = 1";
                sql += " union SELECT ButtonNum, Description FROM StationSetup WHERE ButtonNum = 2";
                sql += " union SELECT ButtonNum, Description FROM StationSetup WHERE ButtonNum = 3";
                sql += " union SELECT ButtonNum, Description FROM StationSetup WHERE ButtonNum = 4";
                sql += " union SELECT ButtonNum, Description FROM StationSetup WHERE ButtonNum = 5";
                sql += " union SELECT ButtonNum, Description FROM StationSetup WHERE ButtonNum = 6";
                sql += " union SELECT ButtonNum, Description FROM StationSetup WHERE ButtonNum = 7";
                sql += " union SELECT ButtonNum, Description FROM StationSetup WHERE ButtonNum = 8) as A order by ButtonNum";

                SqlCommand cmd = new SqlCommand(sql, conn);

                SqlDataReader reader = cmd.ExecuteReader();

                while (reader.Read())
                {
                    switch (myint)
                    {
                        case 1:
                            button_1_M.Text = reader[1].ToString();
                            button_1_C.Text = reader[1].ToString();
                            break;

                        case 2:
                            button_2_M.Text = reader[1].ToString();
                            button_2_C.Text = reader[1].ToString();
                            break;

                        case 3:
                            button_3_M.Text = reader[1].ToString();
                            button_3_C.Text = reader[1].ToString();
                            break;

                        case 4:
                            button_4_M.Text = reader[1].ToString();
                            button_4_C.Text = reader[1].ToString();
                            break;

                        case 5:
                            button_5_M.Text = reader[1].ToString();
                            button_5_C.Text = reader[1].ToString();
                            break;

                        case 6:
                            button_6_M.Text = reader[1].ToString();
                            button_6_C.Text = reader[1].ToString();
                            break;

                        case 7:
                            button_7_M.Text = reader[1].ToString();
                            button_7_C.Text = reader[1].ToString();
                            break;

                        case 8:
                            button_8_M.Text = reader[1].ToString();
                            button_8_C.Text = reader[1].ToString();
                            break;

                    }
                    myint++;
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show("There is an error" + ex);
            }
            finally
            {
                conn.Close();
            }
        }

What am I doing wrong?

Also, where are you running into problems? Calling this method from the other form? The other form will need to be able to reference an instance of this form somehow. Passing 'this' into the constructor of the other form from this one and then storing it there in a field member until it's needed when you hit the save button is one way to do that.

I was able to create a data binding within the form that fixed the issue I was having.
