C# - Populating Dropdownlist Using MVC2 Based On Another Dropdownlist (Cascading)
Sep 18, 2010I am making an application that deals with vehicles. I need two DropDownLists:
Makes: All Vehicle Makes
Models: Models that belong to the selected value of the Make DropDownList
How is this done in MVC2? My Idea: Do I use an ajax call when my first list is selected and then pull back the Models to bind to the Model DDL? How would model binding come into play that way? UPDATE I posted what I ended up doing as an answer. It is super simple and works great. You can use a get too if you feel so inclined, but you have to specify that you want to like so... return Json(citiesList, JsonRequestBehavior.AllowGet);
C# - How To Implement Caching Of Static Files
Mar 15, 2011I use a Masterpage (asp.net webforms) on my site and I woluld like to implement caching of some static files, like javascript, css etc.
I've tried adding the following to my page_load (in the masterpage) but when I use Fiddler the static files are still under "no-cache".
protected void Page_Load(object sender, EventArgs e)
{
// Set cache for 1 hour on all computers and servers.
// ... Proxies, browsers, and your server will cache it.
Response.Cache.SetCacheability(HttpCacheability.Public);
Response.Cache.SetMaxAge(new TimeSpan(1, 0, 0));
}
What am i doing wrong here?

C# - Cascading Dropdownlist Without Postback?
Aug 10, 2010I have a .aspx page having two dropdowns, the data to be loaded in them is usually static(but may change everyday), the first dropdown always displays the main categories and the second dropdown is initially empty.
Now, the requirement is:
As the user selects a category from the first dropdownlist, the second dropdownlist should populate based on the selection just made.
The road-block:
This should be done without a postback. My boss wants something like the drop downs on this page.
So what I gather is, I'd have to retrieve the data from the database on page load event, store it in the cache(or somewhere else?), then use javascript to handle the selectedindexchanged event of the 1st dropdown, use the data from database stored at pageload and populate the second dropdown according to the selected value of first dropdown.
P.S.- I'm a beginner ASP.Net C# programmer and have no knowledge of Javascript.

In your code. i tried using this code and facing a tiny problem. In above mentioned code 'ddlContinents.ClientID'.val stores integer value in contentId for obvious reasons but the requirement of my code is different. i want to pass text which is selected instead of id no.for example if mumbai is listed as second option and i select mumbai it should store mumbai in contentId instead of 2 i.e. integer value.

AJAX :: Cascading Dropdownlist Has A SelectedValue Which Is Invalid?
May 20, 2010I think this needs to be a sticky since this is not solved anywhere that I have been looking... I have been googling this for a while now and came across the answer by shear luck and a simple typo when I was writing the code...
Problem: I have 2 dropdown lists...
ddllist1 and ddlist2... Both are code-behind populated via a sql DB.
they are cascading lists via the ajax control.
I am trying to dynamically populate them with values from a DB for edit reasons.
When I try to get them populated I kept getting the error...
"dropdownlist has a SelectedValue which is invalid because it does not exist in the list of items"
Solution:
1) get the values from the DB or from where ever...
2) create a sql select to get the values from the ddl db
3) set the ID of the first DDL control to cddcontrol1.SelectedValue = id (this is a number)
4) set the value of the DDL to the string value ddlist2.SelectedValue = value (this is a string)
here is the code.
