C# Get Custom Attribute Of Hidden From Request.Form
Jul 22, 2010
I have some code which is rendering some custom attributes of Hidden Control (without runat=server).
Something like,
And I have a lot of these hidden elements on my form.
When I submit the form, I am looping through a set of ids, say 1200 to 1250, so I will read controls based on that, and also hidden with Request.Form["hdn "]
Now problem is, as we know we get value attribute from form when we do Request.Form["id"] for hidden, I want to read my custom attributes from hidden element. Is there any way? Note that, I can not touch the rendering part here.

I'm using HttpModule to capture requests to the web server. Before processing the page I'd like to check the values contained in some keys of the Request.Form collection and according to some logic change if necessary. I'd like to do this when BeginRequest event is fired. The problem is that the Request.Form collection is readonly.

My Request.Form keys are all prefixed with ctl00$container name$ and then the key I want.
How can I get the regular key name working?
Visual example from the immediate window:
I want to use:
? request.Form.Item("stationIdea")
but it won't work because the key is:
ctl00$content_innovation_body$stationIdea
as retrieved by
? request.Form.Keys("4")
so only this works:
? request.Form("ctl00$content_innovation_body$stationIdea")

We're trying to implement functionality that intercepts, inspects, and alters if needed data in the Request.QueryString and Request.Form collections.
Since Request.QueryString and Request.Form are readonly, is it possible to use a HttpModule to do this without Reflection or Response.Redirect?
We're thinking that we can construct a new HttpRequest, and replace the original one. Would there be any implications in doing this?
I know mocking this object is impossible without using HttpRequestWrapper, but wasn't sure whether ASP.NET sets other things beyond the constructor.

This is a input
<input type="image" src="<%=Url.Content("~/images/shopping-cart.jpg")%>" alt="shopping cart" id="btnshoppingCart" name="btnshoppingCart" value="shoppingCart" />
when i browse the page with firefox and click on the input Request.Params["btnshoppingCart"] != null or Request.Form["btnshoppingCart"] != null is statisfied.
When i browse the same page with internet explorer 8 and click on the same input Request.Params["btnshoppingCart"] != null or Request.Form["btnshoppingCart"] != null is not satisfied. When i used the watch i saw that there is no key by the name of "btnshoppingCart" in either Request.Form or Request.Params if input is clicked from internet explorer. However when it is clicked from firefox there is value "shoppingCart" inside Request.Form and Request.Params against "btnshoppingCart" key. One more strange thing that i observed was that are two keys "btnshoppingCart.x" and "btnshoppingCart.y" inside both Request.Form and Request.Params whenver clicking is done from both internet explorer and firefox. This is happening against all inputs of type image irrespective if the input is present inside a html form or not. Forms are created like this
<% using (Html.BeginForm("Action", "Controller", FormMethod.Post)){%>
The version of internet explorer is 8.0 and firefox is 3.6.6

In order to use hidden input, does the hidden input must be inside a form?
Is there any strategy to perpetuate the hidden input value between requests? So far I guess it's through query string / URL?

Dispite what the topic subject says, I really want the opposite. I panel with a form and validations that's hidden. I also have another form that I'm trying to use on the same page, but the page won't validate because of that hidden form. Is there any way around this? Can you tell the brower NOT to validate just those hidden fields?

I have an ASP.NET application designed for a Windows CE device that needs to take in information from a scanned barcode. The device sends the scanned data as string input with a crlf to whatever field has focus. I set up my page with a textbox that takes the input and posts back to look up the item.
Now, I'd like that box to not be visible to the user, but IE complains when I set focus to it if the field is "visibility: hidden" or "display: none". I've tried moving it off screen using absolute coordinates, but setting the focus scrolls the window to the new location.

Supposing I have a user control like this <MyTag:MyWidget runat="server" /> I am wondering if I can do something like <MyTag:MyWidget runat="server" MemberHeight="400" PublicHeight="200" /> So that in MyWidget.ascx I can have <div height="<%=IsLoggedIn ? MemberHeight : PublicHeight%>"> or something like that...? Because I want the height to vary in each page that is using this widget.

I want to create a single custom authorization attribute to be added to controller actions that require authenticated users.
My first shot at this, so I may have it all wrong
Got 3 Roles which corresponds to 3 Areas in my application (Client app, so I'll just call them RoleOne, RoleTwo, RoleThree and AreaOne, AreaTwo, AreaThree).
Each area have similiar (to a point) views and actions, like Sign Up, Area specific home, etc.
In the attribute I want to determine the current area, controller and action. Then I just add code like:
If not logged in, and in AreaOne, go to AreaOne Signup (etc)If logged in as RoleOne, and AreaOne Home is requested, go there, but if AreaTwo Home is requested ,go to AreaTwo Signup So in my attribute class I need to determine the current area, controller and action, and see what kind of user we have logged in (if any)
Using ActionExecutingContext it seems I can determine the contoller and action method names, however I cannot find the Area name, and altered the attribute to be called like this:

I am trying to create a minimum length validation attribute which will force users to enter the specified minimum amount of characters into a textbox
public sealed class MinimumLengthAttribute : ValidationAttribute
{
public int MinLength { get; set; }
public MinimumLengthAttribute(int minLength)
{
MinLength = minLength;
}
public override bool IsValid(object value)
{
if (value == null)
{
return true;
}
string valueAsString = value as string;
return (valueAsString != null && valueAsString.Length >= MinLength);
}
}
In the constructor of the MinimumLengthAttribute I would like to set the error message as follows:
ErrorMessage = "{0} must be atleast {1} characters long"
How can I get the property's display name so that I can populate the {0} placeholder?

Is it possible to access a parent class from within an attribute.
For example I would like to create a DropDownListAttribute which can be applied to a property of a viewmodel class in MVC and then create a drop down list from an editor template. I am following a similar line as Kazi Manzur Rashid here.
He adds the collection of categories into viewdata and retrieves them using the key supplied to the attribute.
I would like to do something like the below,
public ExampleDropDownViewModel {
public IEnumerable<SelectListItem> Categories {get;set;}
[DropDownList("Categories")]
public int CategoryID { get;set; }
}
The attribute takes the name of the property containing the collection to bind to. I can't figure out how to access a property on the parent class of the attribute. Does anyone know how to do this?

I've create a custom attribute for my web pages... In the base page class I've created I'm trying to pull if that attribute has been set. Unfortunately it does not come back as part of the GetCustomAttributes function. Only if I explicitly use the typeof(myclass) to create the class. I have a feeling it's due to how asp.net classes are generated.

I have a class containing the following ConfigurationSection:
namespace DummyConsole {
class TestingComponentSettings: ConfigurationSection {
[ConfigurationProperty("waitForTimeSeconds", IsRequired=true)]
[IntegerValidator(MinValue = 1, MaxValue = 100, ExcludeRange = false)]
[Code]....
The value for the property 'waitForTimeSeconds' is not valid. The error is: The value must be inside the range 1-100.
If I change the IntegerValidator to have an ExcludeRage = true, I (obviously) get:
ConfigurationErrorsException was unhandled
The value for the property 'waitForTimeSeconds' is not valid. The error is: The value must not be in the range 1-100
If I then change the value of the property in the .config to a number higher than 100, it works.
If I change the validator to just have a MaxValue of 100 it works, but will also accept a value of -1.
Is it possible to use the IntegerValidatorAttribute with a range like this?
Edit to add
Confirmed as an issue by Microsoft.

To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".
I got this error at time of running ma published website but only for 1page this error occurred how it can be solved.

I am working in a school and we recently installed a new server running WinServer 2008R2. I want to be able to point people to a URL on our intranet and have them fill out a simple registration form and have this data written to a database. It would also be nice to have some data auto-populate (such as their name).
Is it overkill to set up a sharepoint server and try to do this with Access Webforms? Could I use something like dotnetnuke and find a module that works? Or how about options for writing custom forms?
