c# - Defer form updates -


Is there a way to postpone a form by updating / restoring while manipulating controls?

I am using

TableLayoutPanel to control my form, and I want to add / remove individual user controls dynamically in different cells of the table on the runtime.

When I do this, the screen update is very slow, and some are blinking. 

  tablelayout.SuspendLayout ()

SuspendLayout () seems to have no effect.

It depends on the control; Look for BeginUpdate / EndUpdate or BeginEdit / EndEdit , etc. (and try them try / ultimately blocks). Note, however, there are only these methods in some controls, and they are not bound to an easy interface, so this is a little manual. For example: 

  listView.BegginUpdate (); Try {{int i = 0; i & lt; 100; i ++} {listView.Items.Add ("item" + i); }} Finally {listView.EndUpdate (); }

Note that data-bound controls may have other mechanisms to disable data-related changes; For example, the binding list has a settable RaiseListChangedEvents , which lets you turn off notifications when you edit the data, you can see things like "virtual mode."

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...
