Mvc Html Drop Down List Helper Isn't Selecting Option
Jul 4, 2010
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 have a requirement in my application that, while saving the application, need to get all the value from drop down list and pass it to the view model. But application should not allow the user to select more than one item from drop down list manually, ie, only one value at a time. My view model is like ...
public class ListManagement
{
public IEnumerable<selectListItem> InactiveProduct { get; set; }
public string[] InactiveProductSelected { get; set; }
public IEnumerable<selectListItem> ActiveProduct { get; set; }
}
[code]...

I am trying to set the item that is selected from a drop down list based on what it in the database for that particular record. I am filling the dropdown list with a SQL DataSource I have tried a couple of example that I have found for selecting the item in the list but I am always getting the first item in the list as the selected item. This is what I am currently working with:
Code:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If IsPostBack Then
Else
Dim ID = New Guid(Request.QueryString("ID"))
[code].....

I have a dynamic dropdown that is populated from sql. The user is supposed to select an option from the dropdown, then click a search button on the form to return some results based on that selection. It works fine if the dropdown gets populated with more than one record. However, if only one record is returned, that one record can't be selected. Whether you select it or just leave it alone since it's the only one, when you click the form button (search button), no results are returned b/c the dropdown selection must not be actually selected.
I've included the relevant code below. First the DDL, then the datasource, and finally the C# code in the if (!Page.IsPostBack)

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 } )%>

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 have three dropdowns that are used to choose a date (day, month and year). I want them to initially display today's date. They are being populated with code like this:
[Code]....
So the user changes the value to whatever they want and hits the Submit button and I try to collect the values they have chosen...
Code:
DateTime returnDate = new DateTime(Convert.ToInt32(myRYear.SelectedValue), Convert.ToInt32(myRMonth.SelectedValue), Convert.ToInt32(myRDate.SelectedValue));
But the #@#$!@# thing returns today's date!
This is not what I want obviously. Can anyone tell me where I'm going wrong? Why doesn't it return the date as chosen?
If I remove the myRDate.SelectedIndex = DateTime.Now.Day line from the initial population statement the 3 dropdowns are set to 1/1/2010 but the chosen values are passed to the database correctly.
Is there another way to set the initial selection that will not affect the dropdown for all time.

I have a drop down box with values that shows on loadUnited States Canada Now I have a function that is checking the users value from the database which is fired on a button click. What I plan on doing is comparing the string like if United States(db value) == United States (dropdown value) then go ahead and select United States in the drop down. When I do this I am getting the right value selected but it is making all the values the same for all records.

What is the best way to do the above? Basically i have a drop down list box with a list of names pulled from a database. When someone selects a name i would then like to populate two further boxes with the persons Login ID and Email address which are held on the same DB. I have currently been using Combox1_selected index change and then running a select query on the database to fill in the other fields - unfortuntly this is too slow. There must be a better way then this? I will also need to put the values in a DB in a later stage so will need to be able to retrieve these values.
As an infopath developer this can be done easily on InfoPath using a filter - is there anything similar in ASP.net

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 %>
<%} %>

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.
