View 9 RepliesPopulate Dropdownlist From Another Dropdownlist With Objects In MVC 2
Dec 5, 2010I 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.
Populate DropDownList From WebDataGrid?
Dec 16, 2010I 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?
Populate A DropDownList With AJAX?
Jul 26, 2010I 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?

Proper Way To Populate Dropdownlist Based Off Another Value?
Dec 21, 2010I'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.

Populate Dropdownlist From Years In Database?
Jan 22, 2011How 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...
