I know this is a very debated topic, and usually when you are thinking about this as a solution you might want to rethink your UI logic.
I know I can pass validation using ClientScriptManager.RegisterForEventValidation. But, I'd really like to know. Is it possible to remove event validation for a single control? Is there a way work around for this?
I'm modifying a DropDownList, from the client side after it's rendered.

I have a web application and I want to provide anonymous access to a couple of the web services in it so that we can access the web services from computers without a windows login on our network.
I've tried the stuff here Disable authentication on subfolder(s) of an ASP.NET app using windows authentication. I've done this:
[Code]....
These both "work" in that they allow access to the web service for anonymous users. However, it seems that IIS still sends an authorization challange because when I access the service from a browser I get a box to enter my username and password. If I hit cancel I get access to the page anonymously. However, some of our clients don't handle this well and just fail because of the 401 return code.
Is there a way to completely disable the windows authentication on that single location such that IIS will not try and establish a windows authentication?
I currently cache everything possible on my site (images, JS, CSS). There is only one JS file that I need to be loaded fresh every single time. How do I omit just one file from caching, using web.config, whilst leaving everything else cached?

I have 3 cascading dropdown lists in an update panel. To submit the values of cascading dropdown without error it needs to turn eventvalidation off. Is there any way that i can avoid turning off the event validation and still use cascading dropdown?
View 1 RepliesI have 2 UpdatePanels in the same Page, and each one contains a GridView with some datta. I am using UpdateMode="conditional" because i only want the GridViews to be Filled when needed. So the data in each GridView is loaded only if the user asks for it, and it's not loaded again unless you need a change in the grid (sorting or page changing).
GridViews are filled with data from a DataBase, but I only read the data from the Database when needed. So, in first Page_Load, any data is readed. If the user wants to see the data in GridView1, the data in GridView2 is not loaded from the database, and viceversa.
My problem comes in this situation:
User enters the Page.
User ask for the data in GridView1 (UpdatePanel1 does the job)
User ask for the data in GridView2 (UpdatePanel2 does the job)
Now, the user can see both gridviews in the page. If he tries to change the page index or to sort data in GridView2, everything goes fine. The problem comes when he tries to change the page (or sort) in GridView1 (because in the callback to retrieve the data to GridView2, GridView1 was not filled, so the data the user is seeing is there because of a previous callback). The user gets an Event Validation Exception, and i don't know how to avoid it. I think it's because the server "thinks" that GridView1 is empty, because of the callback to load data to GridView2, where GridView1 was not filled.
I want to use two meta:resourcekey in single control is it possible?

Kindly let me know how this can be done.

View 2 RepliesBefore I get to the question, let me give a bit of background. I'm trying to develop a custom caching mechanism that I can apply to custom built user controls. (Please be aware that I know that there are some built in caching mechanism in .NET) Depending on certain flags set declaratively in the mark-up the control should load a cached version of its previously rendered content or execute normally (and if certain flags are set it should generate a cache of its content for next time it loads). I would like to be able to pass certain flags declaratively in the mark-up and being able to check their value at Page Init and, depending on the flag value, determine whether the control should load a cached version or not.
<uc:MyUC ID="N1" runat="server"
CacheProp='<%# SomeEnum.A | SomeEnum.B |SomeEnum.C %>'
PropA='<%# this.SomePropA %>'
PropB='<%# (this.SomePropB %>'
PropC='<%# this.SomePropC %>'
/>
The problem that I'm facing is that as far as I'm aware I can only get the value of the properties declaratively assigned in the mark-up if I called the DataBind(). However I'm faced with two problems: Firstly calling this.DataBind() from within MyUC will trigger the binding of all its child controls which would defeat the purpose of the cache; also all user controls have been built so that they will not call DataBind() before the LoadComplete event has fired, so to make sure that the parent controls they live in has done its initialisation and has computed the properties that are declaratively passed to the child user control (ie PropA, PropB, PropC).And now the question: is there a way to bind the CacheProp property so to retrieve its value without data binding all other properties and without triggering the data binding of all its child controls?
When designing an ASP.NET user control my standard way for creating say a details view would be to create a property of the desired type on my page and would set the property in the page load based on the supplied query parameter. I feel I'm probably doing more work then necessary. If I could encase my view inside a container then I could merely have it databound and thus make everything declarative.My question is what would be the lightweight container/controls that would be appropriate for databinding a single object?As a second question, how can I handle invalid query strings with this method?
View 1 RepliesI have a stored procedure that returns 3 tables within the single recordset it returns. If I set a SqlDataSource to get data from this procedure, it works, but it only returns the first table. I want to have a GridView display the data from the 2nd or 3rd table using a SqlDataSource, but I can't figure out how to specify a particular table.
While there are some posts discussing this out there, I can't get a definitive answer about whether or not this is even possible (?). In a worst-case scenario, I can create another SP that only returns the 3rd table - but that creates a little maintenance headache that I would prefer to avoid.
For context: First of all, I am new to LINQ, as I have been using SubSonic for quite some time now.
I have two tables, Users, and Affiliates. They both have a very typical schema. The FK that joins them is the UserId field, which is in the Affiliates table. I want to create a LINQ query that pulls the Username from the Users table using the AffiliateId value. The AffiliateId is a primary key of the Affiliates table.
I have tried to accomplish this using many variations of the following code:
[Code]....
In the above query, I expect to get a single row result set. However, I instead receive the entire table of results.
How can I make this work? I have yet to see an example or article out there to do what I am trying to do.
