Web Forms :: Retain Treeview And Its Status On Page Load Inside Iframes

Apr 21, 2010

I have 2 iframes in my page and 2 separate pages linked to each of these iframes. In one iframe page a tab control is placed with treeview on each tabs and the tree items are selectable (treeview with checkbox). On navigation of one tab from other an XML document stored in session is being updated with the selected treenode values.

The second iframe page is places on right side of the page which summarize the selected made on the each tabs. To do this, the page is getting loaded on tab navigation and in page load of that page, the treeview id created and displayed. We created the treeview as an object and kept in session variable then added into a panel. The only modified areas require to be updated instead of binding the entire tree on each tab's navigation.

1. The treeview must retain it's collapse/expand status on tab navigation which is not happening now.

2. When I set EnableClientScript property to true, I'm getting error on expand/collapse as Undefined 'somenodename' error. If I set the value as false, then postback is happening which should not.

Oct 12, 2010

Im developing an admin section for a cms tool and in previous tools i used a master page, which then had a page called verified.aspx. this contained a menu control and then dependant on which menu item they selected loaded a user control into a multiview controlThis works fine accept for some small annoying post back issues (not refreshing data and also the time taken to load the large amount of controls)

I have a master page with 2 content placeholders. Im my verified page (which uses the master), i have a nav menu on the left. Dependant on the item selected fro the nav menu on the left, id like to poplute the content placeholders content with an aspx page (which contains a user control) or just an apsx page

ive seen a couple of articles suggesting iframe, and a couple suggesting nested master pages but i dont believe i can get this to work with nester masters,

Web Forms :: Looking For The Best Way To Load Treeview?

Jul 12, 2010

I am using treeview to display records from 4-5 SQL Tables. Currently I am using 4-5 different stored procedures to retrieve data based on a dropdownlist value.The tree is loaded everytime the value in the dropdownlist is changed by the user.

Is there a faster way to load treeview as everytime a new selection is made, the treeview is binded again. Or is there any way I can optimize the actions I am performing now to bind the treeview?

Web Forms :: Load TreeView Into Session?

Oct 29, 2010

What I have is a simple treeview with one root node, and some childnodes under it. My form allows users to add a new child under the parent, (I'm not pulling anything for the treeview from a database or anything - it is just a treeview with some static nodes). What I then need to be able to do is when navigating away from the page, and then coming back, I want the user added nodes to persist.

I would like to pass the treeview info to a Session variable and then upon page return load that session back into the treeview.I've tried to loop through the treeview to get all the nodes, but my count always comes out to 1, which I'm assuming is my root node. Do I just need to pass that to a session and it'll gather all the nodes under it as well, or do I need my session to be an array and load each node.

JQuery :: How To Load Aspx Page Inside Tabs

At the moment, I have an aspx page with a tabcontainer (ajax toolkit). Inside each tab, I have a little form or other content. At page load, each tab is loaded. Technically I can load the tabs at tabclick (with use of update panels) but this result in unnecessary data traffic.

Is there are a way or example how to use jquery tabs that loads aspx content (html)?

This way we can still use vs.net design tool with aspx pages and load data in a much smarter way.
