Populate Dropdownlist From Another Dropdownlist With Objects In MVC 2
Dec 5, 2010
I am trying to develop a simple MVC 2 timesheet application for my small business. I have a sort of mock model for now until I have a database in place, just to make things simpler while I develop the functionality.
[Code]....
But then I need to populate a second dropdownlist (taskDropDownList for the tasks associated with a particular customer) based on the selection the user chooses in the customer dropdownlist. But how do I do this exactly? I have seen examples with jQuery, but I'm not sure how to apply them to this situation. Also, the examples seem to just populate the lists with string values. I need to be able to access the objects with all their properties. Because the next thing I need to do is to be able to populate the TimeSegments list of the selected task with values from input fields (i.e. the hours worked for particular dates). And for that to be saved to the "model" (eventually to the database) in the controller, how do I get it there, unless the objects are all part of the same model bound to the View? I'm on rather thin ice with this since I still find the connection between the View and the Controller hard to handle, compared with e.g. Windows development, where these things are rather easy to do.

I'm working on a school project where my website idea of choice is one that creates mixtapes (well, you'd download them or burn them from the site, but I need not implement that). The site allows its users to create 6 song mixtapes that are then published into a transaction table.
That part I am fine with. Making the selection page is tough. The way I have it set up is that there are 6 columns with 3 drop downs. First the user picks the genre, then the artist WITHIN the genre, and the song from the artist (GENRE > ARTIST > SONG). So, I would need the ARTIST drop-down list to populate once a SelectIndexChanged occured on GENRE. Same with SONG, but it would use ARTIST instead of genre.
Repeat that 5 more times and click a button, and it would create a table and post it to the database.
I have thought up of 2 ways to go about it.
1) Create a session that expires once the user clicks the "create" button. This would be sluggish, as there would be about 12 page refreshes, and 12 session variables I'd need to store.
2) AJAX/jQuery. This way would be awesome, but I have no idea how in the world to write jQuery in such a manner that on an event it calls a method from a code-behind file.
One thing I found out before my brain went to mush (I've been working on this for 6 hours now), is that one way people have done this is to call a non-related .aspx file that serves as a method. The idea is ok, but how do I go about getting it to update objects on the page the user is currently on? I'd believe there is a simpler way to do this, and am looking to you guys for some guidance on how to dynamically update dropdownlists.

Using ASP.NET MVC 2, I have a model for a view. The view has a dropdownlist of roles that is populated by the model and there is a list below that of checkboxes with a number of privileges. I want to show only specific privileges depending on the dropdownlist selected roleID and have it update the privileges everytime the dropdownlist changes. I know how to do this in web forms ASP.net with absolutely no problem but I cannot seem to figure out where to start in ASP.NET MVC. Can someone please advise me what I need to do or towards a tutorial that will show me what to do? I am a novice in MVC.

I have a WebDataGrid linked to a SqlDataSource to display data. When a row is selected, I want to populate some textboxes and dropdownlists with the data from that row, for editing purposes. The textboxes work fine; I use the following code to select the second field in the grid (Date) and populate the corresponding textbox (I'm using VB): txtDate.Text = currentRow.Items(2).Value However, when I try to populate the dropdownlists using the same code structure, I get the following error:
'ddlType' has a SelectedValue which is invalid because it does not exist in the list of items.
I think the problem may be that the dropdownlists are populated using type_id, while the grid displays type_name. Would this be causing the problem, and is there a way to get around this?

I have a very long list of items for a dropdownlist. As the list is very long, I would like to only show the items in the list if the user actually clicks on the dropdownlist to expand it. I found various tutorials on how to use AJAX with cascading dropdownlists but none explaining if it is possible to have just one dropdownlist which gets populated with AJAX when the user expands it. Are there any extenders coming with the AJAX toolkit that I missed? What would be the best way of achieving this?

I'm running into a minor issue with some ASP.Net code I'm working on. For simplicity sake lets say I have two dropdownlists, one that is full of various items and another that is full of other items, but based off the selected item of the first dropdownlist. I currently set variables into hidden inputs to check to see if the item in the first dropdownlist has changed and if it has to change the second dropdownlist, but I'm also having to check to make sure that if something else causes a postback to NOT repopulate the second dropdownlist as to not lose what is currently selected by the user. This check also allows me to make sure that when I navigate away from the page, the correct values are selected and not something replaced by a postback repopulation.
I'm new to ASP.Net/HTML/CSS/Javascript and the like. I know while what I have works, it isn't even close to being the correct way to do things. correct my ways and figure out the BEST way to solve this current problem. Some good ASP.Net tutorial websites would be nice too as I need to keep improving my skills with it.

write a Subroutine that takes a parameter value of a Folder name on the server, then looks for all subdirectories beneath it and puts this hierarchy into a DropDownList?
So far I can't get the sub to work as it stuggles with the path structure and the obvious requirement to call itself.

How would I setup a dropdownlist to check the dates in the database and populate it based on the years of the dates currently in the database? So if some dates were from 2010 and some where from 2011, it would display a dropdownlist with two options in it...2010, 2011.
I have dates listed in my database for a schedule system and would like to add a dropdownlist so I can only list the dates for the current year by default, then a user has to select a date from the dropdownlist to see any dates from a different year. Otherwise, it just shows all dates, regardless of year...

I have a DropDownList.
I need populate it with item collected in a List<ListItem>.
In my script, collector has been populated properly.
But I cannot populate the DropDownList. I receive an error:
DataBinding: 'System.Web.UI.WebControls.ListItem' does not contain a property with the name 'UserName'."}
<asp:DropDownList ID="uxListUsers" runat="server" DataTextField="UserName"
DataValueField="UserId">
List<ListItem> myListUsersInRoles = new List<ListItem>();
foreach (aspnet_Users myUser in context.aspnet_Users)
{
// Use of navigation Property EntitySet
if (myUser.aspnet_Roles.Any(r => r.RoleName == "CMS-AUTHOR" || r.RoleName == "CMS-EDITOR"))
myListUsersInRoles.Add(new ListItem(myUser.UserName.ToString(), myUser.UserId.ToString()));
}
uxListUsers.DataSource = myListUsersInRoles; // MAYBE PROBLEM HERE????
uxListUsers.DataBind();

I have a DDL and ASP.NET Textbox. I would like to populate the text box with the option I choose from the DDL. I need this to be instant and not use postbacks so it would seem JavaScript would be the obvious choice here. I have done quite a bit of searching but everything I have found seems to be for standard HTML (Selects and Inputs) and these do not appear to work with ASP objects:
<asp:DropDownList runat="server" ID="DDLSalesPerson" DataValueField="keyid" DataTextField="FullName" />
<asp:TextBox runat="server" id="txtSalesPerson" />
My DDL is populated from SQL in the code-behind page.

I've been trying to find a solution to my problem for about 2 days now, and have found nothing. I am new to .net and not really sure how to accomplish this. I have 4 tables in a database, Vendors, RepairCos, Cons, ConRepairHistory. What I'm trying to do is make a page called SendOutForRepair.aspx that has a insert item template where the first control is a dropdownlist that is attached to the Cons table (got this figured out) and is populated with the Serial Number field. I would like the selection from the dropdownlist to populate the 2nd control (VendorID) that is also from the Cons table.
example record from Cons Table: Serial number VendorID
508585 1
so when 508585 is selected in the dropdownlist, it would populate VendorID with 1 (this is my issue)once this happens, the user would fill in the other fields (hours, issue, repairco (also a dropdownlist linked to RepairCos table), RA Number, DCI, DPU, DRB, Cost, Record (which is a identity field and primary key for table) and when the insert link is pressed will insert all 11 fields as a new row in the ConsRepairHistory table. so the new record in the ConsRepairHistory table would look like:
Serial Number VendorID Hours Issue RepairCoID RA Number DCI DPU DRB Cost Record
508585 1 2250 alarming 2 20222 11/16/2010 11/17/2010 null null 3
the RA Number, DCI, DPU, DRB, Cost all allow null values.
