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?

Forms Data Controls :: How To Force Control Input Format In Decimal Field In GridView

Mar 6, 2010

when updating a decimal field in a GridView all is fine when using e.g. "2.3" ("." to separate the fraction!)

However, when using "2,3" I get e formatstring exception!

I tried "regularExpressionValidator/RequiredFieldvalidator" but did not succeed! Tried also with FormatString like {0:n}.....

Questions:

is this controllable by "Culture / UICulture" in web.config (played with it without success!

How do I best check for correct input i.e. force "." as separator

Can I use the "DataFormatString" property for the appropriate GridView field (like {0:n}) ......

Input Elements Don't Render The Value Passed In MVC?

Mar 19, 2010

I have a page that renders a hidden value from the model:

<%=Html.Hidden("myName", model.myValue) %>

Since I am passing a value in the value parameter, you would think it would output that value, but it doesn't.The code for rendering input fields has the following:

string attemptedValue = (string)htmlHelper.GetModelStateValue(name, typeof(string));
tagBuilder.MergeAttribute("value", attemptedValue ?? ((useViewData) ? htmlHelper.EvalString(name) : valueParameter), isExplicitValue);

Basically, if the ModelState (which contains posted values) contains a value for the "name" passed, it will use that value instead of your passed value to the helper method. In my case, I updated the model and my updated value wasn't outputted.If I pass a value to a method, I expect that value to be rendered.

So I am new to ASP.NET MVC and I would like to create a view with a text box for each item in a collection. How do I do this, and how do I capture the information when it POSTs back?

MVC :: Iterating Through Form Elements With Same Name?

Mar 21, 2011

Currently, I have a list of PhoneNumber objects that I display. Here's an example of the output of the view:

[Code]....

Notice the naming of these elements: name="existing_phone[labels][6]", name="existing_phone[numbers][6], name="new_phone[labels][]", name="new_phone[numbers][].Back in the Classic ASP days, I recall being able to do something along the lines of:

[Code]....

And that would give me a 2d array of phone numbers to work with. This doesn't seem to work in .NET. Has anyone tried to do something similar that can point me in the right direction?For new phones, I should simply be able to iterate through each item and insert into the database. For existing phones, I should be able to update (or delete if the label or number are blank) records based off of the id number supplied in the array.OR..if anyone has a better, alternate solution, I'm open to something else.

As you know not every elements is a form element and from accessbility point of view the screen readers have what is called 'forms mode' which only interact with form elements. Can anyone calrify why is that in ASP.NET?

.NET MVC : Ignore Latter Route Elements In Url For A Form's Action

Mar 2, 2010

I have a URL /products/search where Products is the controller and Search is the action. This url contains a search form whose action attribute is (and should always be) /products/search eg;

<%using( Html.BeginForm( "search", "products", FormMethod.Post))

This works ok until I introduce paging in the search results. For example if I search for "t" I get a paged list. So on page 2 my url looks like this :

/products/search/t/2

It shows page 2 of the result set for the search "t". The problem is that the form action is now also /products/search/t/2. I want the form to always post to /products/search.

My routes are :routes.MapRoute( "Products search",
"products/search/{query}/{page}",
new { controller = "Products", action = "Search", query = "", page = 1 });
routes.MapRoute( "Default",
"{controller}/{action}/{id}",
new { controller = "Home", action = "Index", id = "" });

How can I force Html.BeginForm(), or more specifically Url.Action( "Search", "Products"), to ignore the /query/page in the url?

I'm currently using a Rijndael encryption/decryption method through c# however this is making the encrypted names too long to be passed in a post. Is there a better way to get decent encrypted names? my purpose is to have the names encrypted before the post happens so if someone views the code behind the names are already encrypted.

Select Form Elements In JQuery Based Upon An HTML Table?

May 13, 2010

I am working on some ASP.NET web forms which involves some dynamic generation, and I need to add some onClick helpers on the client side. I have a basic outline of something working, except for one huge problem.

There are multiple HTML tables, each generated by a different ASP.NET web control. Each table can contain overlapping field names, which is causing a problem with my JQuery click event handlers. The click event handler is linking to unintended form fields in addition to the intended form field.

I have provided a simplified sample version of the code below. This code is trying to set the value of textbox box1 when a particular radiobutton is selected in the table with id=thing1. Obviously, the jquery code will be triggered for the form fields in both tables.

The tables are dynamically added to the webpage based upon different conditions. It is possible that no tables will be loaded, only 1 table, or both tables might load. In the future, other tables could be added. Each table comes from a different .net web control.

Other than renaming the form fields to make sure they are unique across all user controls, is there a way to have JQuery act only on the intended form fields? In other words, could the table ID be incorporated into the JQuery code in a manner that does not become a nightmare to maintain later?

[code]....

I'm building a shopping cart page that could potentially contain dozens of separate items. Each item has a collapsible panel that contains several form elements that can be used to customize it. Most of the cart is wrapped in an UpdatePanel so that I can avoid a full postback when the user makes changes. When there are many items in the cart, there are of course many many postback elements, all of which are included in the raw form post, even though each post is really only triggered by the change of a single element
