flowdocument - Bookmarking WPF's FlowDocumentReader -


I am trying to save and restore the status of the document within the Flow Documentstrack to create the bookmark feature. There is no demand or search feature creation available to be publicly accessible, I am left with the following options:

  1. Instead of using the flow document page weaver Every time the window is saved, the shape is resized and it is reloaded as the app is reloaded.

  2. FlowDocumentReader's document loop through all the elements of the property, an on-screen hit test, then using the reflection to use the internal text features, after that text Is used to get back in time.

  3. Serial the entire control.

  4. Write your document viewer control. No 1 is disturbing because I have to confiscate the options of viewing two pages and scrolls of the Flow Document Reader. This also means that the user should search the saved page before getting the chance to resize the window. It is weak and probably will break if the user says, the resolution switched between the sessions.

    No 2 is a gaudy hack that will probably work, but will be slow and completely broken if the interior ever changes.

    No. 3 is looking like my best bet, but it only allows me to save / restore the current status, does not set arbitrary bookmarks.

    No 4 is too much work; These controls are completely , I just need one attribute ...

    Know about this Is there any other way? It works well for page views, but not for scroll view, which is fine

. P>

Reader type is the flow documentstrider , and there is flow document in the document.

Set the bookmark: 

  var paginator = ((IDocumentPaginatorSource) document). DynamicDocumentPaginator as DocumentPaginator; Var status = Pageitator. GetPagePosition (paginator.GetPage (reader.PageNumber-1)) as TextPointer; Bookmark = Status. Paragraph;

Restore the bookmark: 

  bookmark.bringinetview ();

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...
