. Net Basics

1: When the command calls the stored procedure, if the output is dataset, Selectcommand Command object Connection It should be pointed out first, otherwise catch will be empty for a lifetime ..

2: If the varchar field of the stored procedure isX. xThis format is prone to subtle silly errors. Do not miss it [].

3: if the events of the default server control of the ascx file are not overwrittenNo automatic delivery! Remember.

4: page. registeronsubmitstatement is used in the ascx file...

5: viewstate has soared a lot of useless data in the true state...

6: clearly understand the order of events, such as the difference between onsubmit and onclick...

7: Pay attention to the relationship between page_load and _ dopostback,

8: If you dynamically load ascx on the page, you can clearly identify the operations to be performed by page_init. Do not abuse user control and custom Server Control (Key Points)

9: The CS file framework should be clear, and the final integration should be completed.

10. If you use a third-party online editor, you 'd better use the framework. OK ?!

11: do not add a comma to the source after compiling multiple CS files.

12: JS loaded in the fifth point can be developed independently. In onsubmit, because the form has only one ascx,

13: system errors are all marked with error codes (which can be written in the help document of the XML document later, and can be shared in multiple languages). This is a good idea.

14: when the control uses loadcontrol, the page attributes are not recognized, and only the inhert of the page is modified.

15: Pay attention to this stored procedure:

Create proc spage
@ Pagesize int,
@ Destpage int
As
Set nocount on
Declare @ ID int
Declare @ startid intselect @ startid = (@ destpage-1) * @ pagesizeset rowcount @ startid
Select @ ID = ID from [crm_articler] Set rowcount @ pagesize
Set nocount off
Select * From t_member where ID> @ ID order by ID
Go

The()Whether there is a great relationship.

16: do not try to modify the global variable in page_load. It does not have that function.

17: with a tone of uncertaintyProgramThe necessity of not reading.

18: the background uses the framework techniques (style, JS, and class) to be reasonably arranged. Try to leave the background as independent as possible without relying on some front-end namespaces or classes.

19: Using (context = system. Web. httpcontext. Current)

20: Try to make the compiled output file concise and independent. The function is to compile a module into a file, but do not open the module (usercontrol) and common, because usercontrol has assembly problems.

21: Reading XML files from a disk is very slow. Do not always read the files. You can put them in the cache.

22: The reader or datareader must read the file.Close ();
