I would appreciate any suggestions.

MVC :: post To An action It gets Null Values In Hosted Enviroment?
Jul 12, 2010I am having a problem where when I form post to an action it gets null values in my hosted enviroment although if I use a model to bind to it works fine. Everything posts and works correctly when I run the project.
So far I have tried to pass the form fields back as parameters on the action and get the value through the context request. Both work fine but as soon as I publish it to the hosted enviroment, it doesn't work. in the view I have:
<%=Html.TextBox("subject") %>
<%=Html.TextBox("comment") %>
for the action Method:
[HttpPost]
[Authorize]
public ActionResult Reply(int? id, string subject, string comment)
{
//Some code...
}
I have verified that it is hitting the action but the subject and comment values are null. I am guessing I am missing something simple, maybe a security setting in the config, that is causing this since I am still fairly new with MVC. I am running VS 2008 with MVC2.

Split Strings From DataReader (Array) To Different Arrays?
Aug 11, 2010I have a datareader wich return several strings like:
ACTIA -ATSD-PKW-ACTIA-MultiDiag
TEXA -ATS-PKW-Texa-Prime"
MASTER-ATSV-PKW-Master-Master"
The strings are separted by the "-"
The idea is that I split the strings in to several dropdownlist, example:
Dropdownlist 1: (Actia, Texa Master)
Dropdownlist 2: (ATSD, ATS, ATSV)
Dropdownlist 3: (Actia, Texa, Master)
Dropdownlist 4: (MultiDiag, Prime, Master)
The problem is: How should I do this? I've search several hours on the internet but can't find anything about how to split strings from a datareader to several different arrays.

MVC :: Post Method In MVC - Public ActionResult MyPost Obj.labels Is Null Whereas Name And Description Contains Updated Values
Feb 17, 2010I am using ASP.net MVC for the developement. My Model class looks like
class MyModel
{
string name;
string desc;
string[] labels;
}
When I bind this model to the view, all the values are displayed on the view successfully. But on Postback method public ActionResult MyPost(MyModel obj) obj.labels is null whereas name and desc contains updated values. why is it so?
MVC :: Model Binding To Non-null Arrays Fail. Is This A Bug?
Mar 12, 2010I have several models that implement a array property using null object pattern in the following manner:
[Code]....
The problem is that any time I attempt to bind to a property of this type the DefaultModelBinder.CollectionHelpers.ReplaceCollectionImpl method wants to call ICollection<T>.Clear() and then ICollection<T>.Add() on the zero length array.
The real issue seems to be in DefaultModelBinder.BindComplexModel() method however. The method contains an explicit check for arrays and special handling to account for the fact that they don't support clear/add functionality. The problem is that the check stipulates that the array model must also be null. If it is non-null, normal ICollection<T> handling ensues which presumes support for clear and add. Can any one explain why the null check is there? It seems to me that either 1) the null check should be removed to permit replacement based binding to non-null arrays or 2) an explicit error stating that non-null arrays are not supported should be thrown.
I vote for the former. I can understand that in general, replacing an existing model with a refrence to a different model would be considered a bad thing. The calling code would not expect this in general and it could lead to hard to find bugs. However, in the case of arrays, if the calling code expects the array property to be modified at all, then I think the normal expectation would be that such modification would occur via replacement of the array.
Web Forms :: Get Post Data As Array?
Apr 13, 2010I was wondering if anyone knew how to get post data as an array in ASP.NET c#. The reason being is that I have a dynamic form with form fields generated and named based upon what it finds in the database and therefore do not know the form fields being submitted, only their prefix.
View 1 RepliesC# - Pass Array Of Strings Via Jquery Post?
Nov 23, 2010What I have is a table that holds 3 input elements, They represent order, name, value. The user can add a new row of 3 inputs to add as many of these sets of data as they want.
To accomplish the dynamically adding in of inputs I use jquery's clone method. That works fine and I am able to iterate through each and grab the values, however the real pain I am having is that when the user has entered in all of the data I want to pass that data to an asp.net page through jQuery's post method. How do I go about passing an array of strings so that I send this format to the asp.net page, and when I've done that how do i parse the data on the asp.net side of it.
Desired Data Format:
["Name|Link|Order", "Name|Link|Order", "Name|Link|Order"]
jquery Code so far:
$("#saveBtn").click(function (e) {
e.preventDefault();
$("#addPanel").slideUp(300);
//Perform Save Operation
var saveString = "";
$("#addTable tbody>tr").each(function () {
var o = $(this).find(".hsaorder").val();
var n = $(this).find(".hsaname").val();
var l = $(this).find(".hsalink").val();
saveString += n + "|" + l + "|" + o ;
});
////// Create Array here or some other method?
$.post("/modules/H/Modify.aspx", { OBVIOUSLY SOMETHING GOES HERE});
// Remove all but top table element to return to original state
$("#addTable tbody>tr").not("#addTable tbody>tr:first").remove();
});

Web Forms :: Events In Control Fired First - DatatypeID Null?
Jul 30, 2010I am building my first user control and am facing the following issue: my host page calls the user control:
protected
void DropDownList1_SelectedIndexChanged(object sender,
EventArgs e)
{
TextBoxRegExValidator1.DataTypeId = DropDownList1.SelectedValue;
}
I pass a string value (1,2,3,etc) via public method called "DataTypeId". The problem is that all the events in the control are fired first so dataTypeId is always null:
[Code]....
I am sure there are many ways to achieve my goal but since I am a beginner I dont know what they are. All I am trying to do is to have a user control TextBox which will work with a Listbox in a host page. The listbox will pass the data(1 - String; 2 - Xml) and so on. Then I change the regular expression in the user control and return that to the form. If there is an easier way to do that or a sample control out there which achieves the same goal.

C# - HttpWebRequest POST Adds A NULL Value To Form Variables
Jan 10, 2011I am attempting to call a RESTful service using an HttpWebRequest object via POST. I am attempting to pass 1 variable with the Request body which contains a url encoded string. I see the request when it hits the server; however, it shows 2 form variables. The first is Form[null] and the second is my variable.I am attempting to locate the source of this NULL key; however, I cannot. Any ideas on how I may be able to remedy this since it's throwing issues when I attempt to use it with the Nancy web framework for .Net.

How To Pass Values To A Javascipt Array
Oct 6, 2010I am trying to implement the autocomplete method for textboxes.
I would like to use the example based on jquerys autocomplete provided here
<head>
<link href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/base/jquery-ui.css" rel="stylesheet" type="text/css"/>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/jquery-ui.min.js"></script>
<script>
$(document).ready(function() {
$("input#autocomplete").autocomplete({
source: ["c++", "java", "php", "coldfusion", "javascript", "asp", "ruby"]
});
});
</script>
</head>
The first and Main problem is that i do not know the way of passing my values to the source:
By saying that i mean, supposing i have a a server-side ASP.NET function GetTheResults as listof(string) or GetTheResults as string ()
how am i supposed to pass those values as source required by the auto-complete?
The second problem is that the specific way does not use AJAX.
Which means i guess on the load of the form i will load all the available values to the source. Isn't that an overkill?
