How To Suppress Click Actions On TreeView With JQuery

Mar 15, 2011

I have the following code:

[Code]....

When running it looks like this: (Image Link) When I click on the Add New link in the Users section I get this: (Image Link) When I click on the ** Move Company** link in the company details section I get this: (Image Link)

Now, everything is working good so far - until I click on a node in the tree within my modal popup. It then exits the popup and I don't want it to. I am not good at JQuery (the JQuery above is not mine) and I tried to suppress the node click events with the commented out code above but all that did was suppress the entire popup from showing!

what I can do to suppress the node clicks from firing the JQuery close routine for the modal popup?

JQuery :: Clear/reload/refresh Async Treeview?

Jun 24, 2010

I've implemented the JQuery Async Treeview (in APS.NET MVC2) and it works fine, but the problem is when the user adds new nodes to a tree (via another interface), there is no way to reload the tree and reflect the new tree structure.

The only way to see the changes in the tree is to shut down the browser (IE8). Trying .empty() on the tree on every reload doesnt do anything.

Heres the page source:

[Code]....

the URL /OrganizationStructure/Browse is only called when the tree is being built the first time..i cant for the life of me get it to rebuild even when the browsers "Refresh/Reload" button is clicked.

Currently I am attempting to create an RSS feed for a blog website I build using ASP.Net MVC with C#. Currently I am simply creating a controller and index page on /feed of the site which does dynamically generate an RSS file but it doesn't work well since the document itself isn't actually an xml file but just a htm file made to look like an xml file.[URL] I attached the code I use to do this but is there a way to instead create an actual XML file so google and feedburner will treat it like a standard rss feed?

DBConn = New SqlConnection(myConn)

C# - Generate Sitemap From URLs In Database?

Oct 20, 2010

URLs are stored in a database, example:

home/page1
gallery/image1
info/IT/contact
home/page2
home/page3
gallery/image2
info/IT/map
and so on.

I would like to arrange the above urls into a tree fashion as shown below (each item will be a url link). The final output would be a simple HTML List (plus any sub list(s))

thus:

home gallery info
page1 image1 IT
page2 image2 contact
page3 map

Programming Language is C# , platform is asp.net

EDIT 1:

In the above example, we end up with Three Lists because in our example there is three main 'groups' eg: home, gallery, info.
