asp.net mvc - Entity Framework creating new record instead of modifying existing one -


I am using unit framework with an as.net MVC application. I have the user permission to create new records and modify existing ones. I am unable to bring any problems to existing records, but when I pass back into the edit unit and try to save it, it creates a new one and saves it and leaves the original unconnected.

I get the object, I successfully recover it from EF using the primary key (such as the ID number for an employee record), and set MergeOption in this way: 

  Context.Sector.MergeOption = MergeOption.No Tracking;

I can find that the right data in the object (using the key of the original record), as far as I call: 

  Context.SaveChanges ();

However, after this, the new record has been created instead of modifying the existing record.

Am I missing something? I would have thought that to recover the object and change some of its values ​​(id) and saving it will only work, but not clearly.

Thanks

NoTracking means that objectstate manager is bypassed and therefore each access to the unit object is brought from the database and new items "

I do not think what you want is nautriking.

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...
