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?

VS 2008 - How To Refresh Or Reload Webpage

Dec 6, 2011

I'm using Visual Web Developer 2008 Express Edition and I'm new to it. I want to refresh or reload a webpage everytime after the event was handled. To expound more, if I have a click eventhandler using the command button which updates a records, I want to refresh or reload the page right after the update event so that the records in my gridview control will be updated as well right after you click the update button. I need the code for that to refresh or reload the page using either c# or vb.net.

Finding Webpage Lifecycle In The ViewState Collection

Feb 8, 2011

When exactly is the view state accessible from the .Viewstate property of a control? From my observations, the closest event is on the Page.PreLoad event (at Page.InitComplete, Viewstate is still unavailable).

However, for controls that implement the IPostBackEventHandler interface the LoadValue() method is called and the .Viewstate collection is available (this occurs after Page.InitComplete and before Page.PreLoad).

Does anyone know of any additional events that can be used to know when Viewstate is available? Or any tricks (not excluding reflection on private/protected/internal members) that can be used to know if the Viewstate has loaded or not?

Vb - What Is The Best Practice For Ouputting Data From A Collection On A Webpage

Apr 20, 2010

I've ported a page from classic ASP to ASP.net. Part of what happens in this page is that a collection of custom types is generated and then displayed via Response.Write() commands. I'd like to get the business logic separated out into a code behind file (and maybe move this all into a user control), but I can't seem to figure out how I'd actually display the collection once it's been generated. I want to specify a master page here, too, so the code can't stay inline. Here's a very stripped down version of the current code:

Enumerating .NET MVC RouteTable Route URLs?

Dec 14, 2010

I'm trying to figure out how to enumerate the URLs of Routes in the RouteTable.In my scenario, I have the following routes defined:

routes.MapRoute
("PadCreateNote", "create", new { controller = "Pad", action = "CreateNote" });
routes.MapRoute [code]...

In other words, if my site is mysite.com, mysite.com/create invokes PadController.CreateNote(), and mysite.com/foobaris invokes PadController.Index().I also have a class that strongly types usernames:

public class Username
{
public readonly string value;[code]....

In the constructor for Username, I would like to check to make sure that name isn't a defined route. For example, if this is called:

var username = new Username("create");

Then an exception should be thrown. What do I need to replace //... make sure 'name' isn't a route URL off root with?

Forms Data Controls :: Bind A Collection Within A Collection To A Gridview?

Jul 26, 2010

I have a list of objects that I want to bind to a gridview. Creating that list and binding it works fine for most of the public properties in that list.

There are some objects contained in each of those objects... for instance there is an Address object.

object.Address.Line1;

object.Address.Line2;

When I bind this to my gridview, I have no issues with stuff like object.DateRegistered, but how can I access things like object.Address.WhatEverProperty? I always get this error:

"A field or property with the name 'xxx.xxxx' was not found on the selected data source."

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.

SQL Server :: Row Not Found Or Changed - Only When Field Is Changed To Something Else Then 0

Sep 14, 2010

For our ASP.NET project for school we had to build a sport event management web application.

We provide the application in three languages (English, Dutch & French) which you can switch all the time. This has worked all the time for all users, well that's what we think anyway.

Yesterday I found out that switching from one to another language isn't working for 2 of our users. So I started testing a bit and I always got this error.

I'll try to explain what happens behind the doors when changing the language:

First of all the current language is saved in a session so we don't have to check the user row every time a page loads. Besides that we save the language in the users row in the database.

Users Table:

Id int
Unchecked
Email varchar(150)
Unchecked

Add Controls To A Collection And Update From Collection?

Mar 25, 2011

I have an ASP.NET app with lots of textboxes all over the page that need updating at various points through program execution.

These textboxes actually belong to a certain class, so for easy updating I thought I could create a Dictionary(Of string, object) and add the control.ID and the control to it and then for updating do something like this:

(in case of updating textbox.text):

[code]....

However the text property of the textbox does not actually get updated. I'm mainly trying to avoid having to manually do textbox.text = somestring for each one of my textboxes every time I have to update them.

I know that if I have set a cookie on a previous request, it will show up in my Request.Cookies collection. I want to update my existing Cookie. Are the cookies from my Request.Cookies collection already copied to my Response.Cookies collection?

Php - How To Embed The Result Of A Webpage Into Another Webpage On Another Website

Mar 23, 2010

I would like to allow users to call my ruby on rails app as a service which returns a 'div' with html content in it, and embed that div into their app (which will not be a rails application).

For example, assume someone has their own php website that has a header/footer template that gets rendered, and a content area of the page that they need to fill based on some html I generate in my rails app. I would like to allow them, from php, to call to my website, get the 'div' I generate, and embed that as html in their php page.

What I'm trying to do is host a service on my site that returns some html content, but actually show that content as part of another site, so that the end user only sees the other site and never really knows about mine.

Also, I can use javascript on the client to do this if that is the only way, but I would prefer the php app to handle this at the server if possible so the client gets the html embedded from the original server and it looks like it all was generated by the php script that generated the entire page. I also want to avoid using an iframe.

C# - Reload A Dropdown On Postback?

Feb 3, 2011

I am populating a dropdown on page load and the user selects an item, click a button (to create a new site in sharepoint) I then want this new site to be shown in the dropdown but I can't get it to work properly. Either the items are duplicated or the selected value is null.

so on page_load I have

getSites();

if the page is a postback I want to reload the dropdown with the new item

if(Page.IsPostBack)
{
getSites();
}

but this of course duplicates all the values so I tried

if(Page.IsPostBack)
{
ddlSites.Items.Clear();
getSites();
}

But even if the site is reloaded with all the items and I select one the value is null, why is that and what should I do to fix this problem?
