In one of the applications I am working on, there are two basic functionalities included: Create and Update. However, there is a need sometimes to add custom code, so I thought of extending the code by allowing 3rd parties to write and embed their own code:
OnCreating
OnCreated
OnUpdating
OnUpdated
Is there a way to enable the above across multiple assemblies? MEF might help here?
Do I need to implement all the required methods on the MembershipProvider and RoleProvider if writing a custom one to use the AuthorizedAttribute in ASP.NET MVC?
There are a few features that I don't want to implement like CreateUser or 'DeleteRole` because they violate the system I will be authorizing/authenticating against.
how page update methods are normally done in a web page with multiple sections? I have a few web pages containing several sections. Each section contains different controls/values and can be saved/updated at any point. Can this be done without creating multiple save functions for each "save" button click in each section? Can this be done with one save class that accepts any number of different values?
Also, i have some page values that should insert if it does not exist and update if the value already exist. Currently, i have to check the database to see if the value exist before inserting and updating. Is there a better way of doing this in VS 2010?

I am trying to implement the webrequest get and post methods. I am accessing a secure site that requires login authentication and was told that instead of sending a login request all the time; login to the site and capture the cookie and use this to send it in the header to get results from the page. In other words let us use google for example. Lets say google required u to login before searching for something. Now I login through my browser and leave the site logged in. Now I send a httwebrequest from my program that includes the cookie authentication details in the request header and get results for say ?param=sports. Now when I increment the page number like &page=3, I am still only getting page 1 results.
Here is some code:

Now I am using the request method GET. This is in the actual request header from the original request.

I am developing a couple of small ASP.NET application and would like to know what pattern. approach do you use in your projects.
My projects involve databases, using Data access and Business logic layers.
The data-access approach that I was using so far is the following(I read in some book and liked it):
For DAL layer:
Creating an abstract class that will define all database manipulation methods to implement.
The abstract class will contain a static "Instance" property, that will load (if instance == null) an instance (Activator.CreateInstance) of the needed type (a class that implements it).
Creating a classes that implement this abstract class, the implementation will be according to the databases (SQL, mySQL and etc) in use.
With this I can create different implementation according to database in use.
For BLL layer:
A class that encapsulates all all retrieved fields , and static methods that will call the DAL classes.

when I reference a assembly. It's reference gets added to the project file in my case ( ABC.csproj)
Also when I take a look at the web.config file there is a section called <assemblies>. And lot of assemblies are added there.
What is the difference between link to the assemblies in the Project file and the assemblies in the web.config file?
How do I implement partial page caching with an AdRotator control? I know it's supposed to do it automatically, but I'm using the AdCreated event to handle stats, and this seems to cause the ad to be cached along with the rest of the page.

View 1 RepliesI'm building a new ASP.NET MVC application (in C#) and one of the requirements is to create a new database of members. For this, we'd need roles to manage the different types of members and profiles to manage the additional metadata attached to each member. So far so good, just use the standard MembershipProvider, RoleProvider and ProfileProvider provided as part of the .NET Framework.
However, the catch is that I'd like to allow different authentication methods. I'd like Accounts and Login Credentials to have a one-to-many relationship (one account can have a number of login credentials attached). A user for example, might have both an OpenID and ActiveDirectory account attached to their account.
However, after experimenting with a few ways we opted for the MembershipProvider route (explained how it was achieved as an answer below).
It appears to be something that is achieved on quite a number of sites, yet a search on here doesn't return anything solid to play around with.
EDIT: After looking around for a good period of hours overnight and this morning - I'm still not convincinced that butchering a single MembershipProvider would have been the easiest option. Does having multiple MembershipProviders give the same effect?
BOUNTY EDIT: With no responses, I am assuming that there is no more optimal solution that the one I posted as an answer. Is this really the case? I'm offering a bounty to try and see if anyone has any further thoughts on this and whether there are better alternatives.
BOUNTY ACCEPT EDIT: I think that WIF is the answer as accepted below, for a .NET 4 release and maybe other versions as it probably works with 3.5. Other than that, maybe a butchered MembershipProvider or adapted one may still be relevant.
First off I'm a week into asp so apologies in advance for silly questions! I am looking to connect to a SQL database table and allow the user to filter the table based on a search box on the asp page. I have written a sql query with a parameter in the where clause, a bit like this:
select col1, col2
from table
where col1 like @my_parameter
Then I pointed the parameter to a textbox on my asp page, and this seems to work quite well. However, I would now like to add an additional search facility which would be a dropdown list. This would be sourcing all the unique values from the col2 in my table abve (there are only about 10 possible values here). But I don't want users to be able to use both of these searches at the same time.
So the bottom line is I would like to offer two methods of filtering the same data table, which search on different columns of the data table. Then the results should populate the same results table, but the user must only be able to use one search method or the other.
I have done a bit of research but couldn't find anything along these lines (I think it is becuase I don't know the words of the things I should be searching for!). I did find information on a standard postback event or cross page posting - not sure which of these (if any) is the best to use for a beginner?
I need to run 5 different WCF methods but within a transaction. Is this possible in WCF? How can I do this in WCf, if it's possible?
The WCF methods will be called from the web service client, which could be an ASP.Net app or Winfoms app.
it may sound a bit newbish question.We have a web service that comunicates with the database and exposes web methods that enables the application to access the database. Each method does only one operation (Insert, Update or Delete). What I need to do is create a transaction that will be consisted of multiple calls to the database, meaning multiple calls of more then one web methods. Can I do that? (I read that if the web method does not throw exception - or ContextUtil.SetAbort() is not called - the transaction will be commited automatically when the web method finishes executing, which I don't want to happen because I want to call another web method in the same transaction, and then manually commit the transaction)
View 2 RepliesMy requirement is to show a page with multiple filters to apply to grid data.
Suppose we are talking about Orders and an order has the following attributes
public class Order {
public int OrderID
public DateTime OrderDate
public DateTime ShipmentDate
public int OrderTotal
public int OrderStatus
}
Inside the jqgrid object I am showing all the attributes except the OrderStatus
The requirement is to create a view that has the jqGrid on the left part a panel on the right
Inside the right panel the user will see a list of checkboxes that represents every possible OrderStatus value and he want to search using both methods (for example selecting the checkbox "Shipped Orders" and then filtering the grid with Amount greater than a value)
I have already configured the advanced filtering (multiplesearch:true) inside the jqGrid object and I am able to create complex filters combining fields and logical operators.
how I can submit even the data from the right panel when the user press the search button?
Update 1:
Preamble: Oleg sample is fantastic but unfortunately does not fits requirements of my customer :(
@Oleg: I do not understand why you think that:
If the data are outside of the grid you will be show the order details on the right pane only for selected row. So the user will have not so good overview of the data.
maybe my description was not so clear but I am not going to show any order detail. To better clarify my requirement I have modified your sample to show you the desired final UI which is as in the following image:
The customer want to filter the data in the grid using two methods or both together:
Using the multiplesearch facilities provided by the grid itself (thanks for the workaround mention) Using the custom Search Panel (the one with the checkboxes on the right) provided
From a functional point of view the requirement is very easy to express: When the user click on a checkbox or make a search using the native multiplesearch I should post values to the server including also the checkboxes state.
To summarize I should:
Add the checkboxes state when a post is made through the native multiplesearch
Add the current multiplesearch state (if any) when the user click on a checkbox
I've created a Gridview in my aspx page, which is referenced in two separate methods in the code-behind file. When I try to run the page, I'm getting a 'does not exist in the current context' error.After a bit of poking on the internet, it seems that I might need to declare the gridview at the class level if it's going to exist in more than one method... problem is, I do that and it disappears from the page altogether.I'm obviously not doing this right - I'm declaring it like this (abridged version):

i need to pass multiple viewdata to a partial view from controller
View 7 RepliesI have the JQuery tab control on my page and each tab will be using the same partial view with a filter set of the model. What is the best way to do this?
The only thing is the data needs to be filtered before it gets to each partial view.

I am tasked with customizing a third-party web application. Since the application is updated (ie new files are copied over the existing files) several times a year, I was hoping that I could put my custom code in separate files -- sort of like having asecond code-behind file for each page that is modified.
View 2 RepliesI have view that dynamically adds multiple partial views with a foreach statement with the standard <%Html.RenderPartial("partialName", model); %> . The partial view control has just a label and textbox control. When I view the source html generated it correctly has a single form control around all the multiple labels and textboxes. My single submit button, inside the form though does not send any of the form data back to the controller though when using FormCollection.
View 1 RepliesThis project I'm working on have this custom clientside JavaScript validation framework created for (which I cannot change) that show error messages/summary based on your data annotations and a "Validate" method in your ViewModel.
Like I said I'm not allowed to change this, so wont be able to go with suggestions doing that.
What the person that created this did not foresee, is that one might need put several partials of the same type and having the same view model (each in a form) on a view.
So I went ahead and did things the normal way (using Html.whateverFor<model => model.whatever) and wala!....the custom validation thing throws error messages for the specific form fields, next to each form in the view. I was suggested to create a "prefix" for each instance of the view model, and do something like this:
Change: <%: Html.HiddenFor(model => model.AccountNumber)%>
To: <%: Html.Hidden(Model.ElementPrefix + "AccountNumber", Model.AccountNumber)%>
Not to mention the tons of jquery selectors and all that I have to go change (and all my view inputs)
(I just hate having to find workarounds for this "custom" everything they created for this project)
I have a View that renders something like this:
"Item 1" and "Item 2" are <tr> elements from a table.
After the user change "Value 1" or "Value 2" I would like to call a Controller and put the result (some HTML snippet) in the div marked as "Result of...".
I have some vague notions of JQuery. I know how to bind to the onchange event of the Select element, and call the $.ajax() function, for example.
But I wonder if this can be achieved in a more efficient way in ASP.NET MVC2.
I have a ASP.NET 1.1 web application page which is built with .net framework 1.1 and in GridView the data is displayed.I want when they select multiple items then data is updated but without the complete postback of the page.
