Web Forms :: Sharing A Structure Or Class Among Multiple User Controls?
Feb 2, 2010
I'm building an application where custom modules may be developed and "dropped in" to the system, where they can be picked up and utilized.
I'm building a forum module and have a user control to create a login/registration region. I plan on using a struct to store the user session data. However, i need this class structure to be shared between the forum module and the login/registration control.
Because the functionality is to be contained in the module's folder, i cant add any assemblies to the app_code folder.
How can i share a class or struct among two user controls?
I am currently working on a project which involves three different websites with a lot of common functionality. At the moment the common functionality is placed in a different website full of user controls.
The problem is sharing the user controls across the multiple websites. Looking around on SO and other websites, the only solution seems the be using virtual directories. As this is a workable solution (we us this at the moment) it doesn't seem as a "clean" solution.
Which "best practices" exist on sharing common functionality (including the GUI/HTML) between different site?
Is it (for example) possible to create a single Web Application project and deploy subdirectories (each with their own web.config) to different production environments?
I am working on a web service that return image tiles for site using Bing Maps. The problem I am having is that All these tiles are created using a single data source. When the bing maps control calls out for the imagery it calls the service multiple times to get the tiles it needs. So if the first thread to go in gets the file all the other threads will fail until the first thread is done reading in the file. Is there an easy way to share this file between all the requests? The flow for what im trying to do is as follows: recieve request open file and read in the data to a custom class - (this is the class I would like to share for all the threads) create the image based on the data return the image.
Is there a way to share class files across web site projects without actually making a physical copy of the file to the App_Code folder of each project?
I am trying to add multiple CSS files across several projects and have added them as a "link" but when I build my solution it does not copy the files. Is there any way to share a bunch of CSS files across several projects?
I am starting an MVC application and designing the class libraries structure at the moment. I started off with the following class library structure as below.
[code]....
As there will be about 3-4 developers working on the project I thought it might be useful to split out each section of the application into their own class libraries so each developer can work on a different section without interferring with each other.
In our application we have 5 tabs e.g. Dashboard, Admin, Reports, Editor, Subscribers. Would it be wise to put each tab into its own class library like below.
i am new to WebServices, i have a ClassDataLibrary.dll which include classes like Users,Products,Articles...
i want to create a structure like this in my webService. as i saw the examples of creating web services the web methods written on the same page. but i got over 50 methods in dll and i want to share these methods with flash so flash user get data using my webService but it will be difficult to find the method he wants so i want to give my webService in a structure like:
Service1.Users // he will finds the methods about users
Service1.Products // he will finds the product methods
how could i do it ? is there any example or something to share with me?
I have a user control with a number of methods. I also have a dataset object that I'm filling in one method, but I also need to access that same dataset (and the data in it) in another.
I am filling the dataset from some xml that I get from a webservice when someone clicks on a button. The data from the dataset is then bound to a listbox control. When someone selects an item in the list control (I have autopostback set to true on it) it then fires off another method and it's this method where I need to access the data in the dataset, but when I check the immediate window it's telling me that the dataset is set to null.
We have about 50 web-sites, running in different application pools, that read from a common cache database (using Microsoft Enterprise Library Caching application block). We currently have a console application which populates the cache at 3AM every morning. However, we want to get rid of this application and get the cache to automatically refresh expired items, using the ICacheItemRefreshAction interface.
We were going to create our cache object in the Global.asax of each of the 50 web-sites. However, my concern is that if we set a cache-expiration policy in Global.asax, that each of the 50 web-sites will trigger a refresh action, causing the data to be re-cached 50 times. We don't want only 1 web-site to set the expiration policies, as then the 49 other web-sites will have a dependency on that 1 web-site, and that's an architecture no-no.
Is it better for a collection of ASP.NET web apps to share the same session database, or should each one have its own? If there is no significant difference, having a single database would be preferable due to easier maintenance. Background My team has an assortment of ASP.NET web apps, all written in either Monorail 1.1 or ASP.NET MVC 1.0. Each app currently uses a dedicated session state database. I'm working on adding a new site to that list, and am debating whether I should create another new session database, or just share an existing one with another app.
I have a ScriptControl that uses an image as an embedded resource and GetWebResourceUrl to generate the WebResource.axd URL. I am currently using GetScriptDescriptors() to send the URL to the JavaScript object.The ScriptControl can be in a Repeater, so you may have 20+ instances. They all use the same images (not customizable through property), so I would like to set the URL once in a variable and share it. I know I could register a script block with a global variable, but would like to avoid that if possible. Is there a way to set a variable within the scope of the control type (global -> control type -> control instance)?
If MVC application has multiple projects (The solution may grow large in future). These projects may share controllers such as application controller accouts controller and there may also be a situation in which namespace of one project is shared by other project. What is the best way of implementing such solution. One approach may be to use areas.
I have built a website and now the customer wants to split it between three different domains. What is the best way to do this? This is what I have so far.
c:/website1/ points to www.website1.com c:/website1/vd1/ points to www.website2.com c:/website1/vd2/ points to www.website3.com
The webhost I'm working with has done it the following way, but now I'm getting a bunch of errors that seems like it's not seeing the App_code folder. Do I need to make a lot of changes? How does this affect the location references?
I have ASP.net application that is basically a data entry screen for a physical inspection process. The users want to be able to have multiple browser windows open and enter data from multiple inspections concurrently. At first I was using cookie based sessions, and obviously this blew up.I switched to using cookie-less sessions, which stores the session in the URL and in testing this seemed to resolve the problem. Each browser window/tab had a different session ID, and data entered in one did not clobber data entered in the other.
However my users are more efficient at breaking things than I expected and it seems that they're still managing to get the same session between browsers sometimes. I think that they're copying/pasting the address from one tab to the other in order to open the application, but I haven't been able to verify this yet (they're at another location so I can't easily ask them).Other than telling them don't copy and paste, or convince them to only enter one at a time, how can I prevent this situation from occurring?
I have a page where I display ASP.NET charts. There are two types of charts and I felt the need to separate them to some extent which I did by using a submenu which looks like this:
Charts > Goals Charts > Reconciliation Charts
Clicking on either of the two chart links will take you to the same Charts.aspx page, but with the query string "Goals" or "Reconciliation" respectively. On the page load of the Charts.aspx page, I receive the query string into a session variable and create the correct charts based on that value. All of this works fine.
The problem I'm experiencing occurs when I open up a new tab in IE/Firefox. Here is the series of events I'm experiencing:
- In the original tab, I will click on the "Goals Charts" hyperlink which loads the Charts.aspx page with "Goals" as the charts type session value. The other controls on the page needed to produce "Goals" charts (eg. drop down lists, etc) are displayed correctly ie. the "Goals" version. At this point, I haven't done anything in this tab except for loading the Charts.aspx page from the "Goals Charts" link.
- In the original tab, I right click the "Reconciliation Charts" link and opt to open in a new tab (I just tested and the same thing appears to be working if you opt to open in a new window as well). When the new tab loads the Charts.aspx page, it loads with the query string "Reconciliation" which it stores in the session variable. So at this point I would expect to have two different, independent tabs: the original tab on the "Goals Charts" track and the second tab on the "Reconciliation Charts" track.
- This is where the problem occurs. I would expect the original tab/window to create a "Goals" chart when I make a selection using the other controls and I would expect the second tab/window to create a "Reconciliation" chart. The problem, however, is that when I go back to the original tab/window - the one which should be a "Goals" chart and which should have "Goals" stored in the session value - when I proceed to create a chart, it's a Reconciliation chart that is created.
Somehow, even though I'm in a different tab or window and I am navigating the site seemingly independently of the other tab/window, it seems to be carrying the most recently populated value from the session variable for both tabs/windows.
I am developing WCF services with single Contract, but now i need to create multiple Contract & Class with multiple endpoints. My class hierarchy is as follows
Employee :IEmployee { } User : IUser { }
I have 2 Interface IEmployee, IUser n 2 Class Employee, User. Creating different endpoints with same binding.
I have build a UserControl with separate code behind file.In that code behind file i have defined some public properties in the Partial class of user control that was automatically generated.Those properties will initialize some properties of controls that are used in the control.Now, in .aspx page i used this User Control and initialized the public properties through code behind of aspx page for dynamic contents.
I'm building a site that can possibly have millions of users (yes ambitious!). Each user can upload an image or two for his/her profile. How would you architect the directories to support this type of thing? I was thinking of having a users subfolder off the root dir where each user will have their own sub-dir that corresponds to their userId created at registration time. I could then upload their profile pics to their corresponding sub-directory under the users dir. Seems straightforward but am I missing anything? Can I have a million sub-dirs under the user dir? NTFS supports it so my guess is YES.
Is there a way to share user controls between various projects ?
I have created user controls like login control, menu control, header control, lost password control and etc and they are all connected to sql database for data.
I would like to share these between various web site projects, it means I have same functionality and the only modifications I can do is within CSS styles.
Do I need to copy modules or is there a way to keep them as shared classes/modules and call what I need every time I need it?
am new to web services and have a quick question. I've some data (an c# class object) that needs to be shared between two different users (of my web service) . all the methods in the web service have a parameter called "sessionkey" which can be used to know what data to share.
I see on the bottom of blog pages a sharing buttons (Twitter and Facebook), where if clicked the link behind (which is normally the blog page url) the fshare button takes the clicker to the blog site facebook page respectively.
How does one do this in asp.net 2 , does one one use the <%# %> in the url part of these share buttons, are there any examples of how this is done?
I am following the Nerd Dinner tutorial as I'm learning ASP.NET MVC, and I am currently on Step 3: Building the Model. One part of this section discusses how to integrate validation and business rule logic with the model classes. All this makes perfect sense. However, in the case of this source code, the author only validates one class: Dinner.
What I am wondering is, say I have multiple classes that need validation (Dinner, Guest, etc). It doesn't seem smart to me to repeatedly write these two methods in the partial class:
[code]....
This doesn't "feel" right, but I wanted to check with SO to get opinions of individuals smarter than me on this. I also tested it out, and it seems that the partial keyword on the OnValidate method is causing problems (understandably so). This doesn't seem possible to fix (but I could very well be wrong).
