Detect ASP.NET version from output HTML? -


OK, maybe this is a trivial thing to know - so common knowledge tags! - But does anyone know the difference in the final output that the runtime was used, will the version go away?

In other words, if you go to a website and you know that it is generated by ASP.NET, there are some things about markup that are running against site 2.0 or 3.5 Or is not it?

no The HTTP headers are configurable by the administrator, so they are unreliable, for example stackoverflow.com says: 

  server: Microsoft-IIS / 7.5

MSN.com says: 

  by X-Powered-: ASP.NET X-español-version: 2.0.50727

and 37signals.com Says: 

  by X-Power: PHP / 5.3.0

and any php site powered by any FTP Network 3.5 Can make an answer or actually have an ASP site when one Perl script that claims At the end of the day, HTTP is the only text and all headers are capable of configuring someone, and their belief is nothing from the perspective of a belief.

I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime.

'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
