Well you need to describe it in better detail than this. Show us what code you are using, what you expect to happen, and what is (or is not) happening, that causes you a problem.

Hi
i'm looking for which how to visual studio generate code when u are working on design mode. for example, suppose u have a web project with visual studio, when u add gridView to yout web page, it generate aspx code in .aspx file on the specific line of page, when u change some default properties of gridView, it add code to .aspx, and when u delete gridView, it delete gridView code that wrote to aspx file. i'm looking for a best way to accomplish this (user design form and my application generate aspx code for it).
can anybody help me ?
thanks

As I suggest below, you have a lot of code to write; none of this happens by magic.

If I understand your question correctly, you want to design an applcation that does the same as Visual Studio. It would allow a user to drag and drop controls onto a form, and your application would generate the actual aspx code, to make it run. This is not a trivial task, IMHO, as you will need to create libaries of classes for all the tools you are to offer, with each class having the properties necessary to generate the images and the code.

Suddenly not sure which of the following constructs I should go with...
I really like the compactness of B, but a bit unsure how my fellow coders would react to seeing the construct.
I can't see how there should be any performance differences (if you know differently - Do tell)
A:
int i;
switch (ID) {
case "a":
i = 1;
break;
case "b":
i= 2;
break;
case "c":
i = 3;
break;
default:
i = 0;
break;
}
B:
int i;
i = ID == "a" ? 1 :
ID == "b" ? 2 :
ID == "c" ? 3 :
0;
What would you use (and why)?

Under normal circumstances I would go for the switch - but as it wouldn't work
case "b":
i= 2;
break;
case "b":
i = 3;
break; I would have to fix it first!
The second is horrible - clarity and readability are much more important than saving space on screen.

The switch, because it's readable and maintainable.

I agree with OriginalGriff.
I'd use switch every time. The conditional operator is fine for small in line statements, but nesting it like that just makes it unreadable too quickly.
The switch is much more readable.

Hi,
if it is just one matching you can go with approach 'B'
otherwise i will prefer the First Approach 'A'
because the Second Type has to be parsed as first and process.
and Even if it is more than 2 matching it is not good practice to use 'B'
because it is not much readable and understandable.and for each case we can
make a comment(purpose) in 'A', But it is not suitable for 'B'
but anyway it depends on the place where use, and the situation where you use,and even the appearance where you use
thanks

It depends on the complexity of the case. I'd definitely avoid the second condition because debugging nested ternary's is an absolute nightmare. In a more complex case than this though, I'd drop both constructs in favour of an Action or Func. Have a look at the Log class in my article here[^] to see how it works.
The basic approach is to set up a set of Actions (or Funcs) that correspond to the operations in your switch statement and assign them to a dictionary (the key in the dictionary is the value for your switch statement). All you need do then is trigger the appropriate action based on the key. In the log sample, this line actually performs the validation:
_actions[level](message);

I'll go for Switch because its easy to track errors in that.

@OriginalGriff
Fixed the switch for ya 
clarity and readability are much more important than saving space on screen.
Agreed 100%
Which is why I posted - As the ?: was/is very clear to me, and I can at a glance understand what's going on, but I'm well aware it's not a construct used that/as often, so wanted to test the waters with other coders.
-debugging nested ternary's is an absolute nightmare
-I'll go for Switch because its easy to track errors in that.
Good point
As this is a *very* simple case I didn't even think of that actually.
But it might need to get more complicated as the code evolves.
Where I'm using it, it's not very likely though - But those are "famous last words", so point taken and agreed to.

Thank you all for the feed back - I'll tidy up my code now

As others said switch is more readable in this case. Also when switch has more labels, compilers use a lookup table (probably hash tables) to implement that and it will yield in accessing all the labels in constant time.

The swtich statement is more readable here, but I think in general swtiches give of a bad code smell:clickety[^]
Especially if they are large or used repeatedly.

In my opinion, a switch on a string value is definitely a code smell. But using if/else or the ternary operator simply to avoid a switch is worse.

No, it's definitely about readability.

neither, because
1) needing such a conversion often indicates a bad design e.g. a bad choice of data structuring;
2) and when unavoidable, i.e. when I do need to map characters to small positive integers, I use a snippet that is based on "literalString".IndexOf(char)
PS: at least two replies mentioned readability, which does not even appear (any more?) in the OP.
I hate it when the OP gets edited, and yes readability is very important.
