MVC :: Getting The ID For A Model Property From HTML Helper
Jan 25, 2011
Is there a way to retrieve the client side ID for a model property similar to how the helpers like LabelFor etc generate the ID? For example, I have a model with a DateOfBirth property. I want to hook up that field to a jQuery DatePicker. Normally, I would hook up the date picker like this:
[Code]....
This works fine but hard codes the DateOfBirth property name. Ideally, I would like to use this:
[Code]....
Is this already available out of the box somewhere? I just created an extension method on the HtmlHelper class that does exactly this, but I wondered if there was already something built-in so I don't have to reinvent and test the wheel.

I think I need to drop in some escape characters, but I'm not quite sure where. Here is the javascript function I'm attempting to call:
function setData(associateValue, reviewDateValue) {
var associate = document.getElementById("Associate");
var reviewDate = document.getElementById("ReviewDate");
associate.value = associateValue;
reviewDate.value = reviewDateValue;
}
Here is the asp .net mvc line where I'm attempting to create a Radio button with a click event that calls the above function and passes data from the model as javascript parameter values.
<%= Html.RadioButton("Selected", item.Selected, new { onClick="setData('<%=item.Associate%>','<%=item.ReviewDate%>' )" } )%>
The above throws a bunch of compile issues and doesn't work. A call such as the following does call the javascript, but doesn't get the data from the model.
<%= Html.RadioButton("Selected", item.Selected, new { onClick="setData('item.Associate','item.ReviewDate' )" } )%>
<%= Html.RadioButton("Selected", item.Selected, new { onClick="setData('item.Associate','item.ReviewDate' )" } )%>
<% String functionCall = String.Format("setData('{0}','{1}')", Html.Encode(item.Associate), Html.Encode(item.ReviewDate )) ; %>
<%= Html.RadioButton("Selected", item.Selected, new { onClick=functionCall } )%>

The strongly typed helpers are now written like this -
<%= Html.TextBoxFor(model => model.State) %>
I need to add a default value to a textbox. In the prior version of Asp.Net MVC it was easy to assign a default value. I thought doing the following would work in MVC 2-
<%= Html.TextBoxFor(model => model.CountyId, new{ value = 840 })%>
This, however, does not work for me in Asp.Net MVC 2. The value is still blank for the textbox. I want to make sure that this isn't some random error that I am having. Has anyone else encountered the same problem? I have searched and searched to find more information on the default property for the html helpers in MVC 2, but I can't find anything. Does anyone out there know how to correctly assign a default value to a textbox in Asp.Net MVC 2?

I would like to exclude one of model's property from the Html.EditorFor. I tried [HiddenInput(DisplayValue=false)] but it renders the property as an hidden input. This could potentially be a security problem. How can we completely exclude a field from Html.EditorFor?

I'll give a very simple example:
at the moment I have to write like this:
<% Html.RenderPartial("hello", new HelloInput { Name = "Jimmy" } ); %>
I would like to be able to like this:
<%=Html.Hello("Jimmy") %>
So I would like to know how create this helper:
public static string Hello(this HtmlHelper helper, string name)
{
return the result of rendering partial view "hello" with HelloInput{ Name = name };
}

It's a little unclear for me on when to use a custom helper method and when to use RenderAction and also when to simply use ViewData instead. Some of their functions overlap slightly.
For example, if I were to create a Category navigation bar, would I create a new helper method and place that in some partial view? I had initially though of doing this, but I read on some blog to use RenderAction instead.
Assume the list of categories is coming from some data source.

I am producing a List(Of SelectListItem) from my database and passing this to a DropDownList Html Helper method on my View via the controller.This works ok but I seem to have found a bug or issue where the DropDownList ignores the Selected property of the SelectListItem objects in the list.I have a provider class in my model which will read the database, create the List(Of SelectListItem) and then depending on whether or not the user is associated with one of the options, I will set the Selected property to True for that item.

I was wondering if it's possible to render an Html Helper in a View inside a codeblock. So instead of:
[code]....
And have this render. Of course as it is, it wont render, so is there a way to programically decide if a textbox can be added without having to have a million delimiters in the page to accomplish this?

I am trying to create 2 Html helpers but that use the String Type as in MVC 2.
1. Html.FileFor Would render something like: <input type="file"
2. Html.Buttom and Html.Submit that would render <input type="button" or <input type="submit" In this case I suppose it makes no sense to have the For.
I know how to do (2) unless there would be something more than rendering the help and defining the Html attributes. However (1) I don't know how to do it

Can we set an id attribute as I would for something like a table column via: for an html dropdown list element that is created with a helper such as:
<% for (int i = 0; i < Model.Trx.TransactionHolidayCityCollection.Count; i++)
{%>
<%= i > 0 ? "," : "" %>
<%= DropDownData.HolidayDays().ToList().Find(item => item.Value == Model.Trx.TransactionHolidayCityCollection[i].HolidayCityID.Value.ToString()).Text %>
<%} %>

In a webforms application, it's possible to add a server control to the markup and then access that control from the corresponding code behind file, but I'm not sure of the MVC equivalent of this functionality.
I've been looking at some tutorials, and it appears that in MVC applications, instead of using server controls, the examples are using HTML helpers, such as Html.TextBox, etc.
However, while I can find examples html helpers in views, I can't find any examples of how these helpers are accessed in the controllers, so I've declared an Html.TextBox in my view but don't know how to access its value in the controller when I hit enter.

I would in normal asp.net use a theme to turn off autocomplete on all text boxes on an entire site. However i cannot do this on MVC because nothing in the theme .skin files seems to work.
I have this in my .skin file:
<asp:TextBox runat="server" autocomplete="off" />
however this does not render at all, of course because this is not how MVC works. Anyway is there any way i can get this sort of thing to work.The site i am trying to do it on is too big to warrant changing every textbox or creating a new HTML helper to solve the issue?

I'm new to MVC and am trying to create some more user friendly controls for use on the Create views. I'm able to render a control using a combination of extensions and partial views, however I am unable to bind to those controls as I am with the out of the box controls like html.textboxfor such as:
Html.TextBoxFor( model => model.Capability_Menu_Group_Id)
Although the controls renders on the create form, the value is not set on create. I would like to set up this same construct used with TextBoxFor for my custom controls.

In my controller I generated a SelectList that I pass to the dropdown helper:<%= Html.DropDownList("abc123", Model.SomeList) %>I look at the querystring for a value, which is a ID.I then loop through all the items in the SelectList and if it is equal to the ID, I do:The controller action then passes this SelectList to the view and then to the Html helper.In debug mode I can see the value does get set to true, but the html renders without selecting the item.

I am new to MVC. why HTML helper methods are inside asp server tags?
for example <%=Html.Textbox("Textbox1")%>
are they equivalnet to asp.net web form server tags. Like in web forms we have
<asp:TextBox runat="server"></asp:TextBox>
If someone can kindly explain.
