        SqlCommand cmd = new SqlCommand("Insert into tbl_BBmgr values('" + TextBox1.Text+"')",con);

Answer 1

Try this :

SqlCommand cmd = new SqlCommand("Insert [TableName] ([ColumnName]) Values(@A)", con);
            cmd.Parameters.AddWithValue("@A", TextBox1.text);
            con.Open();
            cmd.ExecuteNonQuery();
            con.Close();

Update :

SqlCommand cmd = new SqlCommand("Insert [TableName] ([Column1],[Column2],[Column3]) Values(@A,@B,@C)", con);
        cmd.Parameters.AddWithValue("@A", TextBox1.text);
        cmd.Parameters.AddWithValue("@B", TextBox2.text);
        cmd.Parameters.AddWithValue("@C", TextBox3.text);
        con.Open();
        cmd.ExecuteNonQuery();
        con.Close();
