Forms Data Controls :: Populate A Datagrid On Selection From A Drop Down List?

Mar 17, 2011

This is my first post as a newbie to asp.net.

I am in the process of creating a "news system", you can add, edit and delete news. The news items can be entered into the SQL database and you select a category where you want the news item to go into.

What I want is when someone comes to the "Edit" screen, they have a drop down list and what that does is allows you to select a category for you to edit news items from, so rather than at present having the "Edit" page display all the news items, I want people to be able to choose a category that they can edit news items in.

So far my edit page has a datagrid with the following code:

MVC :: Loaded A Cascading Drop Down List Using Jquery. However My Selection Does Not Update?

Oct 6, 2010

I have 2 dropdownlists, the second (department) cascades from the first (division). I use a jquery script to update the second drop down list. When the user clicks submit, the underlying model is updated, apart from the new value for department. 2 ideas I have for fixing this are; a) Generate a postback. Prefer not to do this because of bad user experience. b) With a JQuery change event, make a call to server side and set a ViewData variable that I can use to update the field in the model later.

However there must be a better way. This is the view;

MVC :: Drop Down List As Filter On List View?

Jan 7, 2011

I am trying to create an MVC List View that can be filtered by the value selected from a drop down list.

Selecting a value should repost the page ... Since there is no concept of view state data I am having some issues with this ... I can get the repost to take place but my drop down resets and I am not able to get the value that was selected.




I have tried many of the posts that refer to setting up drop down lists but can't set them up in the content because this is a List View.

Web Forms :: Binding A Drop Down List

Mar 3, 2010

I have a Drop Down List which I need to bind to the database. Here is the situation. I am not using a SQLDataSource. It is built on the n-tier application. The datasource of the dropdown is referring to a method in the C#class. That method has a generic array list which populates information into the arraylist. The Arraylist is the parameter that is returned to the DropDown List.

I have also set the Text property of the Drop down list


However, it is not populating the DropDown list, what should I do?
