design - Pragmatism or purity - Should we rely on GUI framework to store program state? -


I was once accused of creating C # custom user controls. It has a control with a group of openable sections. Control is a label control that the user can click on to toggle between that script / extension status. Next there is an image control that will change the state to indicate whether a particular segment is collapsing or expanded. Somewhere in control, I need a function to return the status of a particular section. The question is whether the function should be restored to the state on the state under control, or should we deposit the state into an additional variable, which is in addition to the current situation beyond the danger of the sink?

Most of the time, when people go with "pure" solutions to such problems, they are just hiding, coupling it Do not remove coupling usually reflects the complex complexity of those problems which they are trying to solve. Since it can not be removed, it can be implemented in a straightforward manner.

Your case is no exception. Unless you feel that there is a good chance for the situation of image control in the future (if you are using a stable framework), by using an additional variable, which is always the image The state should consider the same value as the controller, just replace the apparent coupling with slightly hidden, underlying coupling. It does not benefit you and complexity increases and hence the bug potential.

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

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. 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...
