HttpHandlers / Modules :: Hanging Request.Form Collection Values / Request.Form Collection Is Readonly

Jun 20, 2010

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.

How To Bind Form Collection Back To Custom Model Object That Uses 2 Custom Objects

Mar 23, 2010

What I'm trying to do is rather basic, but I might have my facts mixed up. I have a details page that has a custom class as it's Model. The custom class uses 2 custom objects with yet another custom object a property of one of the 2. The details page outputs a fair amount of information, but allows the user to post a comment. When the user clicks the post button, the page gets posted to a Details action that looks something like this:

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Details(VideoDetailModel vidAndComment) { ....}
[Code]....

The only fields on the form that is posted are CommentText and VideoId. Here is what the VideoDetailModel looks like.

public class VideoDetailModel
{
public VideoDetailModel()
{
[Code]....
I suppose if I added more form fields for the properties I need, they would get posted, but I only need 1 form entry field for the CommentText. If I could get the same Model objects value that were sent to the page to post with the page, it looks like the solution is rather simple. I think using the RenderPartial in the middle of a form is problematic somehow to how the form gets written in html. I can't really put my finger on why things went bonkers, but if I do my RenderPartials before my form and then begin my form with the text entry field and the hidden VideoId, the default ModelBinder works just fine. I was beginning the form, writing the hidden VideoId, rendering several partial views, create my CommentText field, and then closed the form out. The CommentText field would get bound just fine. The hidden VideoId would not. Maybe I missed a rule somewhere about using RenderPartial.

For completeness, the partial view I was rendering took a Comment object and just wrote out it's CommentText data. Several of these objects would exist for a single Video object. All of this data was in a custom type and passed into the View (the main view) as it's Model. This partial view did not have a form and did not have any data entry fields.

MVC :: Passing Json Collection Object From View To Action

Nov 1, 2010

I am trying to send json data from view to controller action. But the issue is the data is not populating in the action parameter List<Score>.

View Model:
public class Score
{
public int QuestionId { get; set; }
public int PrevAnswerId { get; set; }
public int CurrAnswerId { get; set; }
public string CurrAnswerName { get; set; }
}

Json Data look like:
[
{QuestionId:1, PrevAnswerId:3, CurrAnswerId:3, CurrAnswerName:'Known to Broker'},
{QuestionId:2, PrevAnswerId:7, CurrAnswerId:7, CurrAnswerName:'Completed'},
{QuestionId:3, PrevAnswerId:10, CurrAnswerId:10, CurrAnswerName:'Report'}
]

On window load, I will construct the Json object using "eval()" function and do some operation in the data before its save. On Save Click, I will call the action through the ajax call.

$.ajax({
url: url,
type: "GET",
dataType: 'json',
data: {score: ScoreJson},
contentType: "application/json; charset=utf-8",
success: function () {
alert("succes");
},
error: function () {
alert("error...");
} });

Action:
public ActionResult SaveScore(List<Score> score)
{
// do something...
}

But here score comming as collection of 3 elements with zero(for interger property)/null(for string property) values. When I checked in the request I found the data in "parama" property like.

"Score%5b0%5d%5bQuestionId%5d=1 &Score%5b0%5d%5bPrevAnswerId%5d=3 &Score%5b0%5d%5bCurrAnswerId%5d=3 &Score%5b0%5d%5bCurrAnswerName%5d=Known+to+broker&
Score%5b1%5d%5bQuestionId%5d=2 &Score%5b1%5d%5bPrevAnswerId%5d=7 &Score%5b1%5d%5bCurrAnswerId%5d=7 &Score%5b1%5d%5bCurrAnswerName%5d=Completed&
Score%5b2%5d%5bQuestionId%5d=3 &Score%5b2%5d%5bPrevAnswerId%5d=10 &Score%5b2%5d%5bCurrAnswerId%5d=10 &Score%5b2%5d%5bCurrAnswerName%5d=Travelers+Report&".

But I am not sure why it is not getting populated in the score list. One full day I spent for this issue but till now I didnt find the solution for this issue.

Web Service - Passing A Base Object With List / Collection?

Apr 9, 2010

We need to create a simple web service in ASP.NET that can be called from PHP or other languages. This in turn will be used to update records in a database for an item submission.

The core part is fairly simple, we have a base set of fields for the object - first name, last name, birth date, city, etc. In addition however we need to accept a list of items associated with that object that can range from 0-n.

Jan 1 2009, ABC
May 1 2010, 123
Jun 30 2010, XXXXX

What would be the best way to structure this so it can be easily passed to the ASP.NET web service and processed as a single call for the entire object? Would passing the list of items as a single delimted string be a wise approach? Ex: Jan 1 2009, ABC|May 1 2010, 123|Jun 30 2010, XXXXX

Forms Data Controls :: Reference To An Object's Collection?

Jan 31, 2011

I have a custom object and a generic collection of this object.When databinding, how can you get a reference to the object's collection similar to how DataRow.Table works? I understand I may need to write code to handle this but I'm not sure where to start.I considered adding a property to my custom object class to store the collection in, but would this generate too much overhead setting this for every object in the collection?

DataSource Controls :: Passing Object To ObjectDataSource.SelectParameters Collection

Mar 30, 2010

I'm trying to use an ObjectDataSource's SelectMethod() to retrieve a result set from a sql server database to populate a data table with various stored procs that have any given number of parameters. My approach is to pass an object which contains the stored proc name and information about its parameters into the SelectMethod(). My issue is that I don't know how to actually set the default value. Here is the code I have so far:

ObjectDataSource1.DataObjectTypeName = "WebApplication1.Children";
ObjectDataSource1.TypeName = "WebApplication1.Children";
ObjectDataSource1.SelectMethod = "Select";

Parameter odsParameter = new Parameter() { Name = "storedProc", Type = TypeCode.Object };

// How do you set the default value to reference an object?

ObjectDataSource1.SelectParameters.Add(odsParameter);

namespace WebApplication1
{
public class Children
{
public DataTable Select(object storedProc)
{
// do stuff here and get db values.
}
}
}

The default value of a Parameter object is a string type. Does anyone know how to set the default value with an object or how I can pass an object into the SelectMethod?

How To Send A Collection And A Few Other Values In Json Form To A Webmethod?

Sep 28, 2010

Upon clicking a button I need to send a collection and a few other variables to server in Json form.For each value in the collection the server code (C# ) wil update those other variables in the DB.

For example there is a ‘classnumber’ collection with values (First, Second, Third, ….),other variables (‘teacher_name’ and ‘subjectname’).For each value in the ‘classnumber’ collection I need to update the ‘teacher_name’ by searching for the ‘subject_name’ in the DB.So I need to pass the ‘classnumber’ collection,’teacher_name’,’subject_name’ values to server in json form. At the moment instead of sending the ‘classnumber’ collection I am sending ‘teacher_name’,’subject_name’,’classnumber’ as variables for each value in the collection ,which requires multiple requests made to the server.

Instead of these individual requests I am wondering if there is a way to send all the data at once to server in json form?

C# - Accessing The Form Collection In An IHttpModule Causes Event Handler Not To Get Called On Default Page

Mar 18, 2011

I've created a simple sample site to demonstrate the issue. In it, I have a Default.aspx Page that has a button on it:

<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
<p><asp:Button OnClick="ButtonClick" Text="Button" runat="server" />
</p>
<asp:Label ID="output" runat="server" />
</asp:Content>

The code behind just sets the label text on the button click:

protected void ButtonClick(object sender, EventArgs e)
{
output.Text = "Button Click!!";
}

I then have an IHttpModule that gets called for every request:

[code].....

And now it's broken again! So to make a long story short, just by accessing the Form collection on the request in the IHttpModule, I somehow screw up the PostBack, and the event never gets fired.

Forms Data Controls :: Bind A Collection Within A Collection To A Gridview?

Jul 26, 2010

I have a list of objects that I want to bind to a gridview. Creating that list and binding it works fine for most of the public properties in that list.

There are some objects contained in each of those objects... for instance there is an Address object.

object.Address.Line1;

object.Address.Line2;

When I bind this to my gridview, I have no issues with stuff like object.DateRegistered, but how can I access things like object.Address.WhatEverProperty? I always get this error:

"A field or property with the name 'xxx.xxxx' was not found on the selected data source."

Add Controls To A Collection And Update From Collection?

Mar 25, 2011

I have an ASP.NET app with lots of textboxes all over the page that need updating at various points through program execution.

These textboxes actually belong to a certain class, so for easy updating I thought I could create a Dictionary(Of string, object) and add the control.ID and the control to it and then for updating do something like this:

(in case of updating textbox.text):

[code]....

However the text property of the textbox does not actually get updated. I'm mainly trying to avoid having to manually do textbox.text = somestring for each one of my textboxes every time I have to update them.
