AJAX :: Repopulate Cascading Dropdown List Using Javascript
Mar 31, 2010I've 2 dropdownlists, both are binded to a cascadingdropdown. Whenever I select an option in the 1st dropdownlist (parent), the options in the 2nd dropdownlist (child) will repopulate based on the options I selected in the parent dropdownlist. I need a javascript function to reset the options of both dropdownlists in their initial state (the prompt text).
I've tried changing the selectedIndex of the parent dropdownlist. However, this only changes the selected option in the parent dropdownlist. It does not reset the child dropdownlist to its initial state (which is supposed to be disabled and without any options). Need the script to reset the chained dropdownlists?

AJAX :: Unable To Cascading Dropdown When Changing Value With A Javascript Event
Mar 15, 2011I'm back with my CascadingDropdown problems.
This one must be the last but not the less annoying.
I have a set of dropdowns ruled by 3 CascadingDropDowns extenders.
I would like to change the value of these dropdowns by javascript.
This works for the parent dropdown but not for the others.
Here is the javascript code used :
$find(element_name).set_SelectedValue(valeur,valeur);
$find(element_name)._onParentChange(null,true); // still wonder what are the parameters for...
This code does not give me any error but nothing change on display.
The strangest thing is that when I check the value of my dropdown with firebug, I get this :
<input id="Pane2_content_CONNEX_ClientState" type="hidden" name="Pane2_content$CONNEX_ClientState" value="D:::D:::">
And the value that I set is "D". But on the webpage, the dropdown displays a "A" which is the last selected value.

C# - Context Popup Hiding After Ajax Postback?
Nov 30, 2010I am using this jQuery context popup menu extension:http://www.trendskitchens.co.nz/jquery/contextmenu/
This context menu is bound against an ASP.NET treeview adding a context menu to all items.All contained within an update panel.In order to select the item when right clicking, I am using JQuery to parse the postback from HREF that would normally fire when the tree item is being clicked, and using eval() against this HREF.This results in a post-back to IIS. Immediately after is my JQuery code for displaying the context menu.The context menu appears briefly however goes as soon as IIS returns the updated page data.Just after some general advice on how people think is best to approach this. I can avoid this by making users LEFT click the tree node prior to right clicking it, but that just seems unintuitive.

AJAX :: Control Toolkit Queries / Context Options Aren't Available?
Nov 5, 2010I've been following Scott Mitchell's ASP.NET 3.5 in 24 hours and have now completed it.
In it, he suggests downloading the AJAX Control Toolkit. I did this because after viewing the samples, it looks fantastic.
The instructions are to unzip, create a new tab and add items.
Done.
(Note: Using VS 2008 Pro writing in VB with SQL Server 2005)
So based on what I know about AJAX from the book, I assumed the newly added items were all drag and drop. They're not. Apparently some are controls, some are extenders?!? How can you tell the difference?
Also, since nothing worked, I found out through a third party site (which wasn't great) that I had to add a line to the web.config file. (This isn't in the instructions!)
[Code]....
Again, this isn't in the instructions.
So my thoughts are that none of this is intuitive or that the instructions are not well written (and I write training manuals for a living).
Oh and things like the PasswordStrength extender "If you want to use a control extender then you should right-click a control such as a TextBox control and select the menu option Add Extender". Well, I would, but these context options aren't available. Not sure why.
