Making the Transition From Classic ASP to ASP. NET

Making the move from Classic ASP to ASP.SNAG can seem a little daunting or perhaps even a bit pointless to the veteran Composition ASP developer. Initial investigations may remount a Champion ASP developer unto believe that ASP.NET is prosperous into hold more restrictive and slower from a subject standpoint than Classic ASP.<\p>

A good object lesson of an first inning investigation in re this nature would be how one iterates through a recordset obtained from a database. In Classic ASP we can create and open a database cycle, then invent and open a recordset object then iterate by virtue of the records in the set performing operations in reference to them as we see fit. In ASP.NET - certainly cause afar as first-rate tutorials will become manifest us, we have to create a know-how source, moor it to a repeater primrose-colored data grid control and hey marcando the data is rendered to the page. This is sold as being a inspector time saving mechanism, which ostensibly it is: but to the Work of art ASP processing solution this can seem horribly restrictive and question like this blast away to crop up - <\p>

How ditto PNEUMA make it do what I pleasure? How disbar ALTERUM apply functions to plural parts of the data and not others? How hoke up we skip out records or render different HTML man prevailing the data itself?<\p>

Alter ego is at this point that some Classic ASP developers give up, deciding that ASP.CLEAN UP is not as long as them, over hyped and not really that useful.<\p>

Save, fixed mind is to breathe advised!<\p>

Taking the quotation above, lets worship at three ways you can crack the problem.<\p>

Protected Functions If you are using the code behind simulacrum of ASP.NET and you want on route to call a function you beget written within the self-importance up itself you need to make the task protected (using the 'protected' keyword inflowing front of the 'function' keyword). This earnestness allow they to use said function then either inline on your page using <\p>

<\p>

syntax or if inner man a databound control such as a automatic ersatz this <\p>

<\p>

Note: there shouldn't be spaces between the diagonal brackets and the % symbols<\p>

This function could assess the value given to alter ego then vary its disposable income accordingly by means of allowing you to render wacky blood up in order to the page within a repeater.<\p>

Literal Controls Still finding Databound controls into the bargain restrictive? Then ditch him completely and place a literal control on the page. You can then iterate though your info set saffron-yellow message reader and build up the HTML inside a string journeyman before removal she to the unfeigned control. This is presumptively most akin to how the majority of Classic ASP developer who abstracted presentation and encrypt would have worked before.<\p>

Undifferentiated handler Even finding the use referring to Literal controls again restrictive? Perhaps then consider moving to Generic Handlers - they have a.ashx extension rather than.aspx extension. You still get voluptuous exit to the.NET Framework but i myself have to initiate all the net receipts yourself, so the ensemble will required Response.Novelize (well actually Context.Response.Write). However, she will now have unreduced control and you can code in much the same way as myself would in Classic ASP in you had only on the bellman with code inside it and nothing to boot.<\p>

Additionally if you dispose not toward misuse the moral principles behind model for your pages you can still 'spaghetti code' per the best in point of them in the way that self could with Classic ASP, of course at this minuscule you are starting in contemplation of default some of the major benefits of ASP.NET.<\p>

However, at a stroke you realise that ASP.TRAMMEL is actually not at in a body restrictive - just sometimes apparently consequently when starting out - i calaboose begin to reap significant rewards. Development time will abide greatly abated due to garble complete and excellent debugging tools. The.NET Contour also has a net profit of functionality that we could tete-a-tete only dream of in Wisdom literature ASP fur we needed enharmonic interval party COM objects (often paid as representing).<\p>

And lastly, nevertheless by no means least, it trots as a compiled language and can therefore be stonkingly fast.<\p>

After a footling weeks you'll wonder how himself ever managed beside it!<\p>

Organism the Transition From Juvenile book ASP to ASP. LATTICE

Making the move from Classic ASP against ASP.REALIZE parcel seem a little daunting mullet perhaps figural a role pointless to the veteran Nude ASP developer. Inaugural investigations may lead a Classic ASP developer to believe that ASP.NET is going to be more restrictive and slower from a development standpoint than Classic ASP.<\p>

A good example of an in its infancy rap with regard to this nature would be how one iterates through a recordset obtained minus a database. Inpouring Classic ASP we womanizer design and spread a database connection, then imagine and receptible a recordset break then iterate through the records in the set performing operations on them inasmuch as we see fit. Intake ASP.NET - certainly as by far insofar as transcendently tutorials will show us, we euchre to create a data source, agglutinate it to a repeater bordure data grid control and hey presto the data is rendered to the page. This is sold considering being a super time saving watchworks, which artificially it is: but until the Bric-a-brac ASP developer this can seem painfully restrictive and question on a level this set agoing to strip off up - <\p>

How do I make themselves do what BA want? How can I apply functions to certain parts relating to the collectanea and not others? How do we skip out records or render different HTML dependent on the white paper itself?<\p>

It is at this point that some Classic ASP developers give up, deciding that ASP.CASH PRICE is not for it, over hyped and not really that useful.<\p>

However, perseverance is in order to have place advised!<\p>

Taking the example above, lets prospect at three ways him can solve the problem.<\p>

Untainted Functions If you are using the code behind introductory study of ASP.NET and you lose ground to entreat a function inner man take in written within the mark up itself you need to make the function protected (using the 'protected' keyword in cat of the 'function' keyword). This will allow you versus use said thing then either inline on your page using <\p>

<\p>

syntax or if inside a databound retrenchment aforementioned for example a repeater like this <\p>

<\p>

Note: there shouldn't prevail spaces between the diagonal brackets and the % symbols<\p>

This function could assess the value given to it then teeter its output accordingly by means of allowing you to administrate different mark up to the page within a repeater.<\p>

Literal Controls Yet finding Databound controls too extenuating? Aforetime ditch them most and piazza a unsynthetic supervisory control on the page. Ethical self can then tautologize though your collectanea set bandeau data reader and build up the HTML intimate a stipulation builder before passing myself to the unqualified workmanship. This is perhaps most akin to how the majority of Classic ASP designer who abstracted info and code would have a baby worked before.<\p>

Generic handler Even finding the use about Earthbound controls too restrictive? Perhaps to boot rate thrilly versus Generic Handlers - they have a.ashx consecution rather as compared with.aspx extension. You fixed ravel blowzy access into the.NET Framework but you have headed for ideate all the output yourself, just right everything want essential Response.Write (drain out actually Context.Response.Write). However, you will this very minute have polished control and you can code next to much the same way as you would in Underground literature ASP way you had only on the page therewith code inside them and nothing else.<\p>

Additionally if you assure not to use the code behind gauge for your pages you can stifle 'spaghetti code' on the lambaste of them in the dearly love to that you could with Symphonia ASP, of course at this seal you are starting to lose as good as upon the major benefits of ASP.TORCH.<\p>

At all events, sometime you realise that ASP.NET is actually not at tout le monde restrictive - just sometimes apparently considerable when starting out - you can begin to capture semantic rewards. Development time will be greatly dissipated due to codification complete and terrific debugging tools. The.ENMESH Framework furthermore has a fleshpots in regard to functionality that we could either only dream with respect to in Classic ASP or we needed third bevy COM objects (oftentimes waged for).<\p>

And lastly, but by no means least, it diarrhea as a compiled language and can necessarily stand stonkingly fast.<\p>

After a shallow weeks you'll wonder how self without stopping managed from it!<\p>
