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;

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/AdminAccounts.master"

AJAX :: Cascading Drop Down List No Longer Loads Gridview?

Dec 4, 2010

I seem to be having a problem loading a gridview using 2 cascading drop down lists. Before I implemented the Ajax cascading drop down list extenders and I just had regular drop down list the gridview that is supposed to load when users choose the appropriate data from the 2 drop down list appears when the submit button was triggered.


When the button event is triggered it looks for the specific value in the second drop down list and calls a specific stored procedure to load the gridview. Now after implementing the cascading drop down lists the page just posts back - there are no errors whatsoever.

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

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:

C# - AJAX Update Panel Action Button Click On Drop Down Selection

Aug 11, 2010

I have the following scenarion. I have a range of drop down menus where a clietn can select. The code below is wrapped in an update panel but without this, the button click fires a method to retrieve the number of products. So for example, an item is selected from ddlCategory, the btnValidate is clicked and the label returns the number of products within that category.I have the following code for an update panel - I'm just not sure how to implement if effectively.

<asp:UpdatePanel ID="UpdatePanel1" runat="Server">
<asp:Label ID="lblSearchResultsStatus" runat="server" Text="Number of results found: "></asp:Label>
<asp:Label ID="lblSearchResults1" runat="server" Text=""></asp:Label>
<br />
<br />
<asp:Button ID="btnValidate" runat="server" Text="Validate Search"
OnClick="btnValidate_Click" Width="120px" />

How do I go about wiring the update panel so that when a drop down list item is selected, the buttong is effectively clicked?
