Installation :: Not Changed The Webconfig, Only Changed Pages' Content/code Behind?

Jan 13, 2010

After some code change I have published my AJAXised web application to the server and the application failes to work properly - something weird is going on, as all .aspx pages are displayed as an ASPX markup text (page declaration, html controls, etc.), rather than a page is being rendered as an html. I have not changed the webconfig, only changed my pages' content/code behind.

C# - How To Reload RouteTable When Webpage Collection Has Changed

Feb 5, 2011

In my Global.asax file on Application_Start I create a certain number of routes in RouteTable.Routes by looping through a list of web pages collected from a database. This works fine, all routes are created and function as required. But in my web application the user can modify the database and therefore the collection of web pages. This means that during the life cycle of the application some of the routes become invalid, and new routes should be added.

What I wish to do is: The moment the user changes something to the web pages collection, I would like to clear the RouteTable and reload it by looping through the (modified) web pages collection again.

Unfortunately the Application_Start in Global.asax is ran only once, namely at the beginning of the application. I tried moving it to Session_Start which results in undesired behaviour due to the RoutesTable being static.

How do I give my user the ability to change the web page collection on-the-fly whilst having the static RouteTable remain 'in-sync' with it?

Edit

At the moment I do something like this (pseudo-code):

[code]....

The problem is that during the life cycle of the application users can add/modify/delete records in the webPageInfos, how do I update the RouteTable with these changes?

Forms Data Controls :: Gridview With Save Button - How To Tell If A Row Changed

Feb 1, 2011

I have a Gridview with about 6 templated columns hooked up to SQL, with a Save button below the grid.

When save is clicked, I loop through each row, and write each row back out to SQL.

Can you recommend a good way for me to tell whether the row has changed so I can avoid re-writing the row when nothing has changed?

This is not only for performance, but I also have a request to write out a "Last Modified Date" along with each record. So for that, I would need to know whether the row has changed.

I saw someone mentioned that the Gridview.RowState could be used for this, but I don't see how.

One alternative I see is to re-read each row from the database first, to see if anything changed. Another alternative might be to set a dirty-bit on each Textchanged, SelectedItemChanged, etc, for the row, but I'm not sure where to store that.

C# - Scraping Content From Webpage?

Sep 6, 2010

I need to scrape a remote html page looking for images and links. I need to find an image that is "most likely" the product image on the page and links that are "near" that image. I currently do this with a javascript bookmarklet so that I am able to get the rendered x/y coordinates of images and links to help me determine if those are the ones that I want. What I want is the ability to get this information by just using a url and not the bookmarklet. The issues it that by using the url and trying something like httpwebrequest and getting the html on the server, I will not have location values since it wasn't rendered in a browser. I need the location of images and links to help me determine the images and links that I want.So how can I get html from a remote site on the server AND use the rendered location

JavaScript - Receiving Content From Webpage?

Dec 9, 2010

When I made an AJAX call to an ASP.NET page, I had a mechanism to return some text based on QueryString parameters. Such as :

Response.Write("<text>");

But in the response, I got a lot of extra information about viewstate status. This does not happen in classic ASP or PHP. Also if I ask for the whole page, it returns it with the page directive

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

How to avoid this extra information and pass only the required one?

Currently I am using PHP page for returning things for the same purpose. It works totally fine.
