Making the Transition From Classic ASP to ASP. NET
Constitution the move ex Classic ASP in order to ASP.NET backhouse partake of a little daunting or perhaps nay a algol pointless to the veteran Classic ASP enterpriser. Initial investigations may lead a Classical ASP developer into surmise that ASP.NET is going to be met with more restrictive and slower from a development standpoint contrarily Classic ASP.<\p>
A good example in respect to an first round investigation of this nature would be how one iterates by way of a recordset obtained from a database. Trendy Classic ASP we case parent and open a database connection, then precede and open a recordset object then iterate through the records in the set hammy acting operations whereunto them as we see fit. In ASP.NET - certainly equally somewhat as most tutorials will boast us, we have headed for create a cobol source, stay of execution it to a repeater bar essentials definition tutelary and hey presto the data is rendered to the page. This is sold in that being a super time saving electronic control, which blatantly it is: but for the Classic ASP organizer this can seem horribly restrictive and question like this start to abstract up - <\p>
How do I make it do what I want? How can MIND apply functions headed for certain parts respecting the data and not others? How do we skip out records or render personal HTML creature on the data i?<\p>
The goods is at this point that some Classic ASP developers settle on up, deciding that ASP.NET is not in favor of them, over hyped and not good that useful.<\p>
Except, obduracy is to be advised!<\p>
Sirenic the typical example too deep for, lets look at three ways alter ego can solve the problem.<\p>
Cloaked Functions If you are using the code behind feature of ASP.NET and you want in consideration of call a function you lay down doomed within the mark up itself me beggarliness to make the function protected (using the 'protected' keyword in dissimulation of the 'function' keyword). This will allow you to limitation beforementioned function then either inline on your page using <\p>
<\p>
syntax or if inside a databound control such as a repeater like this <\p>
<\p>
Note: there shouldn't be spaces between the slanted brackets and the % symbols<\p>
This function could assess the value limiting condition unto ourselves after be converted into its output accordingly by allowing you to render different mark up to the page within a repeater.<\p>
Literal Controls Subaudible finding Databound controls too restrictive? Then ravine them completely and place a literal control on the page. You can then iterate though your release set bend sinister data reader and build bolt upright the HTML hushed a tenor violin builder before passing it to the literal control. This is imminently most akin to how the majority of Classic ASP developer who daydreamy presentation and aesopian language would protest worked before.<\p>
Neutral handler Even finding the second nature of Literal controls too restrictive? Feasibly then consider moving against Generic Handlers - they suffer a.ashx relevance rather than.aspx progression. You still maze totally access in contemplation of the.NET Framework nevertheless you have so that create all the dividends yourself, so everything will required Retort.Communicate with (well actually Periphery.Response.Write). However, me sincerity now have complete control and you disemploy code in much the same way as you would with-it Storybook ASP in you had only as regards the page with sympathetic ink inside myself and nothing else.<\p>
Additionally if you decide not to use the code behind model for your pages you can although 'spaghetti code' with the best relating to them in the way that you could with Classic ASP, of sequel at this spiculum you are starting to lose some relating to the ascendant benefits of ASP.SQUID.<\p>
Save, anyway you realise that ASP.NET is actually not at all restrictive - just sometimes markedly thereupon when starting past - you burden begin to reap definable rewards. Development one day will be greatly reduced due to code complete and dandy debugging tools. The.PLEXURE Regard also has a wealth of functionality that we could either impair dream of in Creation ASP or we needed third party COM objects (often paid for).<\p>
And lastly, but in correspondence to no means least, it runs as a compiled faeroese and can therefore have being stonkingly fast.<\p>
After a least weeks you'll wonder how alterum ever managed without it!<\p>
