C# - Getting Value Of Form Field From HttpContext?
Feb 17, 2011
I have declared a form input in my ASP.NET ascx file:
<input type="hidden" id="hidServiceType" name="hidServiceType" value="somevalue" />
And in the web service / web method, I am trying to get the value of this
HttpContext postedContext = HttpContext.Current;
serviceType = postedContext.Request.Form["hidServiceType"];
I can dig down into postedContext.Request.Form and see 2 keys one being "hidServiceType" but "serviceType" variable = "";

We're migrating an application to use IIS7 integrated mode. In library code that is designed to work either within the context of an HTTP request or not, we commonly have code like this:
if (HttpContext.Current != null &&
HttpContext.Current.Request != null) {
// do something with HttpContext.Current.Request
} else {
// do equivalent thing without HttpContext..
}
But in IIS7 integrated mode the check for HttpContext.Current.Request throws an exception whenever this code is called from Application_Start.
protected void Application_Start(object sender, EventArgs e)
{
SomeLibrary.DoSomethingWithHttpContextCurrentDetection();
}
Results in:
System.Web.HttpException: Request is not available in this context
How can I detect whether the request is really available without wrapping these calls in an exception handler and taking action based on whether an exception is generated or not.
Looking at HttpContext in Reflector I see it has an internal bool HideRequestResponse field but it's internal so I can only get to it with reflection and that's fragile. Is there a more official/approved way to determine if it's ok to call HttpContext.Request?
This blog post about the subject says not to use HttpContext, but how, in generic library code, can you determine if it's ok to use HttpContext?
http://mvolo.com/blogs/serverside/archive/2007/11/10/Integrated-mode-Request-is-not-available-in-this-context-in-Application_5F00_Start.aspx
I'm using the work-around mentioned there which is to use Application_BeginRequest and an initialized field to only initialize once as part of BeginRequest, but that has to be done in every calling application whereas I'd prefer to make the library code more robust and handle this situation regardless of where it's called from.

How do you use the http POST method with a Grid View on another page. I am trying to use the POST method to send the ID from the selected row of a Grid View, I am using a link button set to fire the select command and it has the Post Back URL set, from one page and then retrieve the ID value on another page using an Object Data Source. Also, under the Defining Parameters, I am setting the ID parameter to Form Parameter Source and have entered the Grid Views name in the Form Field.

I have been experimenting with code that will clear all of the cookies in an HttpContext.Response.Initially, I used this:
DateTime cookieExpires = DateTime.Now.AddDays(-1);
for (int i = 0; i < HttpContext.Request.Cookies.Count; i++)
{
HttpContext.Response.Cookies.Add(
new HttpCookie(HttpContext.Request.Cookies[i].Name, null) { Expires = cookieExpires });
}
this will error with an OutOfMemoryException because the for loop never exits - each time you add a cookie to the Response, it also gets added to the `Request.

i'm using an example in which i can fake the session.It's for use in a unittest of a mvc controller.In the test i create a controller and then i do this:
FakeHttpContext httpctx = new FakeHttpContext(null,null,null,null,mSessionItems );
ControllerContext ctx2 = new ControllerContext(httpctx,new RouteData(), target);
here mSessionItems is my session and target is my instance of a controller,and indeed, when i'm in a controller reading this.ControllerContext.HttpContext.Session, i have a session, great!but.... i also read the session outside the controller, and there i use HttpContext.Current.Session, and that is null (or actualy, the HttpContext.Current is null).

I have PDF that opens in a browser (iframe) that has standard PDF form fields. I would like the user to fill out all the fields and then press an HTML submit button (located outside the iframe in the surrounding ASPX page) so that all the data in the PDF that was filled out in the PDF Form Fields posts that to another ASPX page.

This is probably a simple question, but I can't seem to find an answer. One of my web pages has an ASP.NET FormView and two SqlDataSource controls. I need to show data from both datasource controls in the FormView. Most of the data will come from datasource1, with 2 or 3 items coming from datasource 2. The way I am trying to do this is by adding a label to the formview, then use custom data binding to get the data from datasource2. However, I can't seem to figure out the syntax for the bind statement

I have a form and stored procedure that inserts the data from the form. It works fine except that if a field isn't filled in it doesn't insert a NULL into sql it inserts "".
I've tried a few different ways but none seem to insert NULL, the one below still inserts "", can anyone point me in the right direction.
Here is the required part of the code, if you require more just let me know.

So if I enter nothing into address1 field it should write NULL to screen but it always writes NOT NULL.

I am getting a FaultEvent when trying to send form fields through HTTPService that contain more than 542 chars.
Initializing the HttpService:
httpServ = new HTTPService();
httpServ.method = 'POST';
httpServ.url = ENDPOINT_URL; //http://localhost:3001/ReportError.aspx
httpServ.resultFormat = HTTPService.RESULT_FORMAT_TEXT;
httpServ.contentType = HTTPService.CONTENT_TYPE_FORM;
httpServ.addEventListener(ResultEvent.RESULT, OnErrorSent);
httpServ.addEventListener(FaultEvent.FAULT, OnFault);
Sending the request:
var params:Object = {};
//params["stack"] = e.stackTrace.slice(0, 542); //length 542 = works
//params["stack2"] = e.stackTrace.slice(1, 543); //length 542 = works (just to show that it's not about the content itself)
params["stack3"] = e.stackTrace.slice(0, 543); //length 543 = fails
I also seem to be able to create many form fields (with 542 length) so that it's not a limit of the request itself but of the form field:
var params:Object = {};
params["stack"] = e.stackTrace.slice(0, 542); //length 542
params["stack2"] = e.stackTrace.slice(1, 543); //length 542
params["stack3"] = e.stackTrace.slice(2, 544); //length 542
// Length > 1600 chars
The receiving party is an ASP.NET 4 site on the same domain and port.
I hope someone already came across a similar restrictions or has some general advice on how to trace this problem down further.

I am using a "Detail View" to edit the data in my "Customer" table. The fields are "CompanyName", "ContactPerson", "StreetAddress", and "City". If I type data into the first field ("CompanyName") and then press the "tab" key, control moves to the second field "ContactPerson". However, if I type data into the first field ("CompanyName") and then press the "Enter" key, instead of control moving to the second field ("ContactPerson") the program closes the form.
Is there someway that I can control the action of the "Enter" key so that this will not happen?
Also, is there any way that I can have control move from the first field ("CompanyName") to a field other than the seconc field ("ContactPerson") if the content of the "CompanyName" field contains the value "Internal"?

i am using this code to reset all my textboxes and Dropdowmlists after the button is clicked:
void resetField(object myObj)
{
//RadioButton rl;
string temp = myObj.GetType().ToString();
switch (myObj.GetType().ToString())
{
case "System.Web.UI.WebControls.TextBox":
((TextBox)myObj).Text = "";
break;
case "System.Web.UI.WebControls.DropDownList":
((DropDownList)myObj).SelectedValue = "N/A";
break;
default:
break;
}
}
i have tested this code and it works great separately .. the only difference is on my project i have DIV, tables, TABs and ContentPlaceHolder. not sure if this can make this code not working.. i am not getting any error..but nothing is happening.

I have an ASP.NET site and I've been doing some work refactoring code to try to remove some long running processes (in the order of an hour) from the actual http Request by creating a BackgroundWorker and sending the work off to that to process. This was running fine on cutdown tests but when I applied the logic to the real code I found problems accessing Session variables from the code running in the Background Worker. It seems that the HttpContext object that was passed has a null session and if I ask for HttpContext.Current I get null back.
I'm assuming that this is because they are in a different thread and that the session and HttpContext.Current are both reliant on being in the same thread. Is there any way I can get access to the Session from the background worker or am I stuck with finding all the variables I need from session and putting them in an usable data structure and then putting them back in session (if appropriate) afterwards? It obviously complicates the refactor massively if I need to do this so I'd rather not.how I might do this other than BackgroundWorker processes

I'm trying to create a SessionManager class which I can use to manage sessions in my MVC applications. For that I'm thinking the best way of doing so is by creating a wrapper class for HttpContext which would then allow me to access HttpContext.Current.Session.
To be honest, I'm not really sure about the whole thing, I just feel it's the logical way of doing so. I also want to create an ISessionManager and ISession interfaces, and then implement them according to my application's needs. For my current project, and for now, I need a InProc session management, but I might need to store session data in MSSQL Server when we decide to expand and use a web farm or a garden. That's why I'm trying to build a sort of an extensible framework right from the start.
Final note, I will be using Microsoft Unity to inject the concrete SessionManager of choice. I believe that's a good way to maintain a certain level of abstraction.
