ASP.NET MVC2 RC : How to intercept or trigger client-side validation before ajax request? -


I have a user name text box on the form that has some validity rules applied through the DataAntiation attributes:

I also have a button next to this text box, which closes a jQuery AJAX request that checks the existence of a username:

< Pre> & lt; Button onclick = "check (this); return false;" Id = "FtpLoginCheck" name = "FtpLoginCheck" & gt; available? & Lt; / Button & gt;

I am looking for a way to share the two together so that click on the "check" before the client-side verification call arrives. / P>

EDIT: To be more clear, I need to inspect or trigger the client side verification result of the text box, when I click on the unconnected button without it.

EDIT: I now check the JSON JS ("form") button. Valid (). Is invalid, but is not displaying general verification message. About

Any thoughts?

OK if my solution is to manually trigger the button Button onclick event: - 

  var validator = $ ("form") ({submitHandler: function (form) {/ * nothing *}}); If return (validator.errorList.length & gt; 0);

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

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. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... '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...
