asp.net - Dataset manually put into the viewstate of a Web UserControl not kept after postback -


I have created a web user control that is placed on the page at design time. Its purpose is to pop up with the grid of objects that the user has chosen so I have got a gridview on it. And in this code usercontrol: 

  as the public property datatable () data. If you do not get the datalet (viewtest ("_ selectGridDataTable")) see VistaStast ("_grigreddatable") or return nothing if Setting the End Gadget (ByVal value as Data.DataTable) ViewState ("_ConnectGridDataTable") = Value and set end and property

So when the user clicks on a button on the page, I put it in the code on the page: 

  SelectGrid2.DataTable = GetContacts () .Tables (0) SelectGrid2.Show ()

And it works fine. Grid pop up (using jQuery) and grid is shown. The problem is, when the user clicks the "OK" button on the user controller, the viewstate ("_giftgrid data") is always nothing and I can not get it because it is in the viewer ..?!? So what does the mean of viewerat actually mean?

Ohs I did not know that viewer is not present during page_int. I took my check for data loading for page load, and now it works. Thanks Mitchell to give me the idea of ​​checking this ..

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...
