I suspect this:
this.txtstatus

Open in new window

Should say:
this.txtstatus.Text

Open in new window

Otherwise it will spit out the object type information, which will exceed the 10 characters that your field will accept.

that's is right carl thank you very much and also I just figured that I forgot to add the Reader in my code now all work fine:

Carl , it seems that any time I'm trying to update I got some issue I think that I'm not really understand the concept updating database columns can you give my some explanation also I would like to now what is the difference between these two update methods

1.
string Query = "update RMSCRM.dbo.sales set Status=@Status, note=@note where ID=@id";
            
           

            SqlConnection Myconn = new SqlConnection(conn);
            SqlCommand cmd = new SqlCommand(Query, Myconn);

            int SalesID = int.Parse(this.txtid.Text);

            cmd.Parameters.AddWithValue("@id", SalesID);
            cmd.Parameters.AddWithValue("@status", this.txtStatus.Text);
            cmd.Parameters.AddWithValue("@note", this.txtNote.Text);

Open in new window


2.
string Query = "update rmsmasterdbtest.dbo.serial set serialnumber='" + this.txtsn.Text + "' ,serialnumber3='" + this.txtstatus.Text + "' where serialnumber='" + this.txtsn.Text + "' ;";

           
            SqlConnection Myconn = new SqlConnection(conn);
            SqlCommand cmd = new SqlCommand(Query, Myconn);
            SqlDataReader Reader;
           

            try
            {
                Myconn.Open();
                Reader = cmd.ExecuteReader();
                MessageBox.Show("Updated Status");
                while (Reader.Read())
                {

                }

Thank you soo much
