Its working just fine, except for the fact, that dropdownlist is populated but selected value is not set.Im using the following code for a dropdownlist in my template:
and its not setting the selected property. I put the code below to SuperModelView, that calls <%: Html.DisplayFor To populate the template and it works just fine.
UPDATE: I`ve tried to investigate the issue, but something is totally wrong. I can share the whole code, not sure where to put it, here or attach with separate files.
@Darin, what other parts should I share, or just share the whole model view and controller files?
I have a list of Key/Value pairs. basically its a List where ViewModel is a custom class of the form
public class ViewModel { public String Key { get; set; } public String Value { get; set; } }
In the View i would need to render Label and Textbox for Key and Value respectively.Im trying to use Html.DisplayFor() however it goes with model and only displays the properties of the model and not the list.I would like to achieve something of the format
I've been all over the Internet looking for an acceptable solution to this issue, but didn't find one, so hopefully I'll have more luck here. I've got a Html.DropDownList control in my application that pulls in a set of values from the database. That works just fine. However, I want to set the selected value in code, which has never worked correctly. This is, in my opinion, one of the worst implementations of Html helpers in MVC. Here's the culprit:
[Code]....
OK, it takes in a list of statuses and gets the text/value options set without a problem, but doesn't ever render the selected value on the option with a value (ID) of "5". I've stepped through the code as it is assigning these values, and it does set the value of that option to select = true, but the rendered html doesn't reflect this. I recall something about this helper using the Model to set its selected value, but why will it not allow the value to be explicitly set? Even better, if for some reason explicitly setting this in code isn't going to work, why allow it as viable code, and just silently fail? I'm all for this coding by convention approach MVC has taken, but when the convention is explicitly overridden in code, the code should prevail, I would think.
I have a MVC dropdown list (Html.DropDownList) with list of Movies populated. I want to retrieve both Title(value field), Description(Text field) when I perform the form Submit. I can access the Title(value field), but I can't access the description. My code sample is below.
In my app I have a criteria builder section that's built using jquery and is pitched back to the controller in a form post and picked up as IList by the model binder as suggested in Phil's post here: http://haacked.com/archive/2008/10/23/model-binding-to-a-list.aspx A really simple way that I'm persisting the criteria across posts is re-delivering the IList object to the view. I'm using a DisplayFor() template for this object, but because it's a list I need to know the index # inside of the template.
I am having a problem with disabling DropDownList based on the chice of 1st DropDownList, there is no post back occuring, and it is a template based web app here is the current code:
what is happening now is page is blank and if I remove the above code everything shows, where I am going wrong. here is the plain and final javascript code which worked:
what i m trying is i hav two dropdownlists inside the gridview... namely say ddonsiteoffsite and ddhours... now what i want is if the selectedtext of ddonsiteoffsite is "onsite" the ddhours should b disabled... i tried the code snippet but ... its not disabling the ddhours... can someone help me please..
I am having a 2 dropdown list, in the first dropdown I have 3company names,for each company I am having separate tables,every table have a empcode, if the user select the company name in the 1st dropdownlist, as per company selected the 2nd dropdownlist it will fill the list of employee codes as per the selection..
I have two pages manager and user both have drop downs as
Week, Months and Years.
User have to enter some data week wise for each months and Manager have to approve that.
To Approve manager select months and week from dropdown on his own page and then navigate to User page.
How does I should bind the drop down so that if manager select 1st week from it's page and goes to view link of user then in drop down of user selected value shold be the same as selected by Manager on his own page.
I am binding months to a list 0-13 items default selection is 0 months duration, and years 0-8 items and 0 years is the default selection.As I know there are always going to be 12 months in a year, I could use selectedvalue or selectedindex without any perceived problem. Is there a reason why I should not use either/or of the two properties to select a list item?
I thought this would be pretty simple, and in fact it's working on another dropdownlist on the same View, so I'm hoping I missed something very small that is easy to fix. Here's my code:
[Code]....
When I step through the code, the 'Active' option's 'Selected' property is being set to true. That's expected. But when the View renders, it's not selected and a look at the page source shows that the selected property isn't set. What is the problem here, and what's the solution?

Now I'm stuck in changing the second dropdownlist. For example, first dropdownlist- select 2, second dropdownlist will change from 1,2,3,4 to 2,3,4,5,6. Other than cascading dropdownlist, it there anyother methods?
