Hi,
I'm building an ASP.NET app with MVC3, EF4. I came across a situation where I'd like to do the following:
1) when the user goes to the index.cshtml page, I'd like to first display 2 drop-down lists so the user can select the categories; the 2nd drop-down list will further narrow the selection;
2) Based on the 2 selections, I want to display the qualified data
Right Below the 2 drop-down lists, on the
SAME page. SO ideally as soon as the user select a value from the 2nd drop-down list, the data will appear immediately below.
Note: the 2 fields for the 2 drop-down lists and the data to be displayed below are ALL from the SAME TABLE.
Now My questions:
1) SelectList: I never used SelectList before; so even though I have an idea that for 1) I should use SelectList, and made the first drop-down list work; but I don't know how to make the 2nd drop-down list work.
2) How to display the data below?
3) Should I use Ajax or can I use it here? I never used Ajax before this.
If anyone can show me some sample code, for both View and Controller, that'll be great! Or provide a link with any sample code so I can get an idea.
Thanks,
Claudia
