AJAX :: Cascading Dropdown And Triggering Events?
Oct 7, 2010I have a big form wrapped in an updatepanel (for other reasons). Inside this form is a section that needs to have it's own asynchronous postback -- there is a cascading dropdown and, based on the selections, you can add a product to a list. Once that list is populated, it can be submitted with the rest of the form.
So in this little section I have :
A Label for testing the button event (the label gets updated)5 Cascading Dropdowns (which are working fine)A button The button event changes the label text. If I click the button right away, it updates the label as expected. However, if I click the button *after* doing any selections on the Cascading Dropdowns, the label does not get updated. Things I have tried:
Removing the updatepanel surrounding the form -- yes, then the event gets fired, but I need it all in the updatepanel.Adding UpdateMode=Conditional -- no changeAdding an update panel just around this section -- no changeAdding Triggers either to the big updatepanel or to one just around this section -- no change
Thoughts?

Apr 15, 2010I am using a master page with a treeview control. I have 2 other pages Summary.aspx and Home.aspx

Client Side Script For Treeview Events?
Dec 27, 2010I have a Treeview with "populateOnDemand" set to true. I want this treeview to keep its state (nodes expanded/collapsed) from one page to another. Viewstate doesn't work because the treeview is different for each page. Here is my code at the moment.
ASPX page :
[code]....
This works well, buf I wish I could avoid the postback everytime the user expands or collapses a node. I know I can set EnebleClientScript to true and manage the events client side in Javascript but I won't be able to use my session variable anymore. Is there a way to achieve this ?

Web Forms :: Events With 2 Controls - Can Give A Priority At The Events
Oct 19, 2010I have a page with 2 Controls, a ListBox and a DropDownList.
In the DropDownList you can select a PLACE.
In the ListBox you can see all DOCUMENTS for the selected PLACE.
If you select a DOCUMENT, the program does a redirect on the selected DOCUMENT.
So, there are an AutoPostBack and an Event (if you select another Item) on both Controls.
The problem is: If I select a PLACE, then I select a DOCUMENT (the pdf document is opened), and then I go back on the page and I want to select another PLACE, the program doesn't select another PLACE, but opens the old DOCUMENT, because there are 2 Events, one to change the PLACE and one to open the DOCUMENTS.
Can I give a priority at the Events?
Web Forms :: Handling TreeView Error Detected By System.Web.UI.WebControls.TreeView.LoadPostData?
Mar 1, 2011Periodically a rash of occurrences of the following error happen. I believe they're the result of hack attempts. Whether that's the case or not, my question is how can I handle the error? I want to avoid unhandled exceptions. The TreeView control is just
a standard .Net TreeView control, not a custom one. If you suggest a code solution, please code it in VB.Net as that's what I'm using.

Web Forms :: Event Handlers Not Triggering Any Longer?
Sep 14, 2010I've been working on a web form that has lost it's ability to respond to most event handlers, though code that I write in Page_Load still fires. No button click or text changed events will fire. This has been working for months, and suddenly stopped. I did a windiff comparison to an older version of the webform, and don't see anything suspicious.

Everything there works fine.However, I want it to run on the Page_Load to automatically display today's events at start up. It refuses and will only update the gridView if I actually click on the calendar.in my Page_Load I have the following code :

MVC :: Using Forms Authentication And Triggering New Rows To Be Added To Existing Database
Nov 9, 2010I'm very new to ASP.NET and MVC2 but I've managed to piece together a project that allows a user to create an entry in the SQL Express database - just like the "MVC Movie Application". However, I now want to utilize the [Log On] Forms Authentication feature. Requirement: when the user successfully registers an account my existing database needs to be updated with a row of data.
Using the MVC Movie Application as an example: the method "public ActionResult Register(RegisterModel model){}" [see: AccountController] needs to be wired to also perform "public ActionResult Create(Movie newMovie)" [see: MoviesController] how is this achieved ? (specifically, to update the MVC Movie application to create a new movie whenever someone registers a new account.)

Web Forms :: Triggering Fancybox Script Using Server Control Linkbutton Or ImageButton
Dec 14, 2010I am using fancyBox Scripts to display a link in IFRAme.
script for FancyBox is
<pre><script type="text/javascript">
$(document).ready(function() {
$("#various1").fancybox({
'titlePosition' : 'inside',
'transitionIn' : 'none',
'transitionOut' : 'none'
});
$("#various2").fancybox();

Forms Data Controls :: Button Event Inside ListView Is Not Triggering Correctly?
Mar 16, 2011I have a ListView (table inside) and it's first row are some TextBoxes for filtering actions.
In the last column I have a button that calls my Search function and filters the records according to the inputs.
[Code]....
My Search function for now only displays a text inside a Label at the top of the page.
When I load the page, I'm using ListViewPesquisa.DataBind() so it shows it's EmptyDataTemplate, but when I click the button inside the event isn't called at all. If I do put some data (any data) in the ListView and it shows it's LayoutTemplate instead, the event is called properly.
I can get around this issue by moving the filter line out of the table, but I'd like to know why is that the button inside the EmptyDataTemplate doesn't work.
