Jan 12, 2011

I am just wondering how you'd iterate through elements in a form input array when you get the FormCollection object on postback?

CheckBoxFor Render Additional Input Tag - Get Value Using FormCollection?

May 18, 2010

In my ASP.NET MVC app I am rendering out a checkbox using the following code:

<%= Html.CheckBoxFor(i=>i.ReceiveRSVPNotifications) %>

Now I see that this renders both the checkbox input tag and a hidden input tag. The problem that I am having is when I try retrieve the value from the checkbox using the FormCollection:

FormValues["ReceiveRSVPNotifications"]

I get the value "true,false". When looking at the rendered out HTML I can see the following:

<input id="ReceiveRSVPNotifications" name="ReceiveRSVPNotifications" value="true" type="checkbox">
<input name="ReceiveRSVPNotifications" value="false" type="hidden">

So the FormValues collection seems to join these two values since they have the same name.

MVC :: Repopulate Form With FormCollection?

Mar 2, 2010

Ive got a scenario where a form is filled in and the action picks it up as a FormCollection. It then carries out validation on it and if it fails sends it back to the form again, however i cant seem to get it to re-populate the form.

If i do something like:

[Code]....

So it just looks for name in whatever is passed over... ideally i dont want to involve a model unless it has all validated fine, but if there is no other way around it can populate a model and do the validation on the model instead...

MVC :: Tables And FormCollection - Renders Data Out To A Form ?

Apr 19, 2010

I have a basic form that renders data out to a form like so (from Northwind):

<% using (Html.BeginForm())
{ %>
<h2>Region Selection</h2> [code]....

In addition, I have a controller that is called when the form is posted back:

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Index(FormCollection collection)
{ [code]...

The problem is that none of the data in the table is being captured in the FormCollection in the Post. The TextBoxes pass data as expected so I know the wireup is working.I read from some other posts that you need a value for the name property - but that did not work. Also, I read that you need to put the data inside a TextBox inside the TD. Instead of grasping at straws, does anyone know the best pattern to pass the data from a Table back into the FormCollection?

btw: I tried to copy/paste formatted test in from Word. No dice. Ugh.

MVC :: Does The Hidden Input Must Be Inside A Form

Dec 10, 2010

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?

MVC :: Check Form Input Is Valid On Submit?

Anyone know how to query Microsoft's Sys.Mvc.FormValidation to see if the form passed it's test so I can prevent the busy animation showing if the form hasn't actually been submitted? Or even some other work-around? In case it's relevant - I'm using Data Annotations for my validation.

Is There A Maximum Number Of Input Controls That Can Be Used On An HTML Form

Jun 3, 2010

I have an ambitious requirement for an asp.net 2.0 web page that contains a table (gridview), and each row in the grid contains 6 select (dropdown) controls for data entry. The number of rows that will be displayed is dependent upon the user's search parameters, which are specified in another area of the page. Unfortunately, with the default (and even basic) search parameters specified, the grid could contain several hundred rows. I've noticed that the browser, in this case IE8, starts behaving rather erratically once I reach a large number of rows -- no documented evidence for the number of rows where this begins to be a problem. For example, trying to view the source of the page results in a message from IE stating that there was a problem with the page that forced the browser to reload it, and I never get the source. Obviously the page loads and renders rather slowly also.

I know that my solution is probably going to involve paging the gridview such that it only displays 20 or so rows per page, and I'll have to write code to handle the saving of changes in the dropdown values when the user changes pages. I can probably turn off viewstate on the gridview also. However, the question I really want to pose is this -- has anyone seen a documented rule indicating the maximum number of input controls that an HTML browser form is supposed to be able to contain? I could not find anything on the Internet after doing a search, and I suspect the answer may be whatever the browser can handle based on the machine configuration it is running on. Any rules of thumb you use?

C# - How To Receive Input To A Hidden Textbox And Submit A Form

Sep 6, 2010

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.

Remove Literals From Input Mask After Form Submit?

Aug 20, 2010

I'm using Josh Bush's MaskedInput plugin for jQuery in an ASP.NET 3.5 Webform app. How to get rid from the literals in the code-behind file after form submit? E.g: a phone input with the mask $("#txtPhone").mask("(99)9999-9999");

In the code-behind:

string customerPhone = txtPhone.Text
Which returns me: (12)3456-7890
But this is what I want: 1234567890

In the plugins changelog page it says I can use mask() method with no arguments to archieve this. But how to do it from the code-behind?!

EDIT

I want to send to the server the unmasked value. How to do that?

Javascript - Creating A Form To Input Multiple Contacts?

Aug 26, 2010

I'm trying to devise a form that will allow me to input multiple contacts. It's a pretty long form so far and I want to keep it as short as possible. I was thinking of just having one set of fields for contact inputting which will add this contact to a list box or gridview but I'm not sure that is the most elegant solution. Could anyone else point me in the right direction to something good I can use?

I'm writing in HTML / asp.net / javascript.

I've written a small class .That has a method for adding and subtracting.

My class file is fine and everything works well when I hard code the integer values. But the moment I try to use textboxes in my methods signature to accept values it complains that this is an inavlid argument. I assume that this is because I used int as my signatures but then how can i use my class to textboxes as input.

Web Forms :: Force C# To Not Rename Input Elements To Work Consistently With Form.GetValues?

Jan 6, 2010

HOW TO Force C#/ASP.NET to not rename input elements to work consistantly with Form.GetValues.

ASP.NET changes the "name" property of input elements set with "runat=server" to match their ID property at run time. This causes server-side calls to HttpRequest_Page.Form.GetValues to now be able to get the expected Form element.

Example:

.aspx page...

<input type=text id=txtMY_NAME name="MY-NAME" runat=server>
<input type=hidden id=hidMY_SECRET name="MY-SECRET" runat=server>

.aspx.cs file:

string csNAME = HttpRequest_Page.Form.GetValues("MY-NAME"); // Fails...
string csSECRET = HttpRequest_Page.Form.GetValues("MY-SECRET"); // Fails...

The reason why this fails is because ASP.NET changes the "name" properties of these controls to match their "ID". Thus at run time they become as such:

.aspx at run-time

<input type=text id=txtMY_NAME name="txtMY_NAME" runat=server>
<input type=hidden id=hidMY_SECRET name="hidMY_SECRET" runat=server>

I do not want ASP.NET doing this. I do not want to change the naming convention of my id properties either. In fact, I need the ID to be different than the name, as I use client side script to change/create/delete controls on the fly.

What can one do?

MVC 3 ValidateRequest (false) Not Working With FormCollection

Dec 5, 2010

FYI I am using .NET 4.0 / MVC 3. In my controller, the following is my code:

[HttpPost]
[ValidateInput(false)]
public ViewResult Edit(ContentTemplateView contentTemplateView, FormCollection collection)

Everything works fine when I don't enter HTML, so I know the proper controller is being fired. Also, I have following set properly in my web.config files:

<httpRuntime requestValidationMode="2.0"/>

I only get this problem when I include the FormCollection (which is needed for this particular Controller). So what exactly am I doing wrong? [I have done what was proposed on the following questions, and they work as long as there is no FormCollection. None of them offer a solution with an included FormCollection] Why is ValidateInput(False) not working? Asp.Net MVC Input Validation still firing after being disabled ValidateInput Attribute Doesn't Seem To Work in ASP.NET MVC

MVC :: Fetching Attribute Values From FormCollection?

Jan 28, 2011

My application writes custom attributes to input controls using Helper classes. And also we are loading the UserControl dynamically so we need to use FormCollection to get the posted values. Is there a way that we can access attribute values from FormCollection object.

Example:

<input type="text" name="textBox1" value="harsha" customAttr1 = "MyValue" />

My question is how can i access the value of customAttr1 from the above eg from inside the controller.
