TreeView client side script

JohnLR — Fri, 04 Jun 2004 14:15:01 GMT

Hi everyone,

Adapting Vikram Bhardwaj's original code for fixing various bugs in the TreeView control, I've written up a JScript library. This code is independant of a given TreeView control, so as long as you setup the event handlers up properly it should work for multiple TreeView controls on the same page.

Please let me know if you find any bugs. Instructions for using this script are found in the opening block comment. Note that the functionality I wanted is slightly different than Mr. Bhardwaj's, as explained in the comment.

If this doesn't format properly, just send me an e-mail and I'll forward you the code.

Thanks!

John LaRusic

	MODULE:		MS IE TreeView Control client script


	PURPOSE:	This code fixes numerous bugs in the Microsoft TreeView


				control, including the ability to allow postbacks


				


				A TreeView object setup to use this library will have the


				following functionality:


					a)	When a given checkbox is checked, the parent check


						boxes will also be checked.  *NOTE* This differs from


						the functionality that Mr. Bhardwaj originally


						supplied.


					b)	If a given checkbox is unchecked, then if all the


						sibiling checkboxes are also not checked, the parent


						checkbox will become unchecked.


						


				There are still the occasional bug in this treeview, and I


				think its tied to the behavior file for the treeview.  If you


				see a bug in this code, please bring my attention to it.  My


				e-mail is johnlr@gmail.com thanks!


				


	AUTHOR:		John LaRusic (with many thanks to Mr. Bhardwaj for the problem


				definition and solution)


				


	CREDIT:		Vikram Bhardwaj wrote most of this code for a single TreeView


				object.  I simply adapted it by making it a bit more portable


				(multiple TreeView objects can share this library) and fixing


				a couple of bugs.  I also formatted the code nicely and added


				comments should anyone want to adapt this.


				


				Mr. Bhardwaj's original post on this code can be found at:


				http://www.asp.net/Forums/ShowPost.aspx?tabindex=1&PostID=301443


				


	TO USE:		Reference this script file on your page and add the following


				event handlers (where "treeview1" is the ID of your tree view


				object)


				


				<script event="oncheck" for="treeview1">


					TreeView_OnCheck(treeview1);


				</script>





				<script event="onhover" for="treeview1">


					TreeView_OnHover(treeview1, event.treeNodeIndex);


				</script>





				<script event="onload" for="window"> 


					TreeView_Setup(treeview1);


				</script> 


			


				


				You also need to add an onclick event handler to your submit


				button to call the TreeView_ReadyForPostback for the tree.


				For example:


				


				Button1.Attributes.Add("onclick", _


					"TreeView_ReadyForPostback(treeview1)")

How to use IE WebControls in VS 2008?

rafferty_uy — Tue, 22 Jul 2008 03:12:36 GMT

Hi,

I recently got my hands on an old ASP.Net 1.1 web application and I am trying to open it in my VS 2008 ide. I'm having problems getting it to compile because of the missing Microsoft.Web.UI.WebControls dll.

After much searching, I found out that I had to install IIS and download and install the IE Web Controls (http://www.microsoft.com/DOWNLOADS/details.aspx?familyid=FAC6350C-8AD6-4BCA-8860-8A6AE3F64448&displaylang=en), please check if the link is correct.

But after installing and rebooting, I still do not see the assembly in my visual studio reference list.

What should I do next?

Thanks!

TreeView Drag and Drop

gogoray — Mon, 24 Nov 2003 19:01:17 GMT

Hello,

I'm trying to figure out how to implement drag and drop in the new IE TreeView control for ASP.NET/C#. It doesn't seem to be possible, can anyone confirm that for me?

I'd like to have similar functionality to the web front end to Outlook...that's a web based tree that you can drag the nodes around. Is this possible? Help!

Thanks a million,

Treeview control and TreeNodeXslSrc error

sakellariadis — Tue, 06 Oct 2009 13:49:56 GMT

I have a treeview control that works fine until I modify web.config to protect static files. Then I get the following error:

Server Error in '/' Application.
--------------------------------------------------------------------------------

The XML loaded from TreeNodeSrc=XMLFile1.xml, TreeNodeXslSrc= did not contain the required outer <TREENODES> container.

Hoping someone can help.

To reproduce, I can use the following TreeView.ASPX file (from http://www.15seconds.com/issue/030827.htm):

<%@ Register TagPrefix="iewc" Namespace="Microsoft.Web.UI.WebControls" Assembly="Microsoft.Web.UI.WebControls" %>
<%@ Page Language="vb" %>
<HTML>
<HEAD>
     <title>XMLIn</title>
</HEAD>
     <body>
         <form id="Form1" method="post" runat="server">
         <iewc:TreeView id="TreeView1" runat="server" TreeNodeSrc="XMLFile1.xml"></iewc:TreeView>
         </form>
     </body>
</HTML>

with the following XMLFile1.XML file:

This works fine, with standard web.config file. However, I want to change the site to protect static files, so I add the following into web.config as the first lines within the <system.webServer> tag:

(For an explanation see http://learn.iis.net/page.aspx/244/how-to-take-advantage-of-the-iis7-integrated-pipeline/) This new web.config file works exactly to protect static files throughout the website, but causes the treeview control to fail. Can anyone suggest a workaround or know the cause?

Thanks!

TreeView Is Causing a Huge VIEWSTATE

MLibby — Wed, 21 May 2003 18:40:14 GMT

Alright now, I'm concerned...

With every node I add to the TreeView it appears that the VIEWSTATE expodentially increases. My tree is small but the size of the VIEWSTATE already has me worried. The functionality of my TreeView requires VIEWSTATE but does anyone have ideas on how to minimize the size of the VIEWSTATE?

Loading IFrame when TabStrip Tab is clicked

imshikha — Mon, 06 Jul 2009 10:20:20 GMT

Hello all,

In our project I am using the TabStrip and Multipage functionality. It's been applied in conventional manner, where all the tabs (Multipage with IFrames) are getting loaded at once when the main page is loaded.

But, with increasing data, the main page (on which this Tabstrip is applied) is taking way too long to load all the Frames of the Tab.

I have 10 Tabs which contains different aspx screen and it takes between 4 - 5 minutes to load all the 10 aspx pages.

I have been searching for two days on internet and found no solution.

Can anybody please help me how i can load the aspx pages only when a particular Tab of the TabStrip is clicked. (Please don't tell me use the SelectionIdexChanged event - as i don't want a postback).

If there is a way to do it asynchronously, that idea is also welcome.

Hoping for a positive reply soon.

Thanks,
Shikha

Is there an update for the tabstrip control to .NET 2.0 ???

I can't figure out how to use the tabstrip in vs 2005. The tabs just return plain text

Looping through TreeView Nodes?

andrea_johnson — Tue, 11 Sep 2007 16:35:33 GMT

Hello,

I'm using the Microsoft Web Control. I'm dynamically loading the control with data from the database where there are parent nodes and children nodes that could be up to 5 levels. I have a Javascript function that executes when a parent node is checked to automatically select all the children below it. Now I have to figure out a way to find out what nodes are selected so that I can process them properly. The only way I see this happening is if I create a hidden variable and loop through all the nodes in the TreeView and add the nodes to the variable if they are checked. However, I'm having a problem looping though the nodes. The only information I found was the SelectNodeIndex property which just gives me the node that was selected.

This is my TreeView Format:

Folder10

Folder1

Item1

Folder2

Item2

Folder 11

Folder 3

Item4
Item5

Folder 12

Folder4

Folder5

Folder6

Item6

Folder 13

Item7

I need to find out which Item was selected in the TreeView. So lets say that I checked the Folder10 and Folder12 (all the subfolders and items are selected automatically). Then I want the hidden variable to hold all the selected nodes in this format;

Variable = Folder10_1_item1 (So the each parent node selected would start of with text "Folder" then the ID of the folder, then an "_" which means there is a child. Then the ID of the subFolder and then the text "item" and then the ID)

So If I selected Folder10 and Folder12 in the TreeView, I would like the variable to hold this information

Variable = Folder10_1_item1;Folder10_2_item2;Folder12_4_5_6_Item6

Can someone please help? How can I loop through each node of the treeview to achieve this.

Thank you

Microsoft Webcontrol tabstrip on Windows Server 2008

InNeedOfAssistance — Tue, 17 Mar 2009 12:32:27 GMT

I'm trying to move webpages from a Windows Server 2003 (where everything worked correctly) to Windows Server 2008. I've worked through most of the problems that have been encountered but am having a problem getting the Microsoft WebControl - TabStrip to work correctly. When the pages are viewed with IE the tabs work fine but when viewed in Firefox the tabs are all smashed together. Has anyone encountered this problem and if so how did you handle the problem? We have a lot of pages that use these tabs so this is a high priority for me to get this working.

Since these are public websites I do need to have the tabs work with all types of browsers. If the MS tabstrip no longer functions on the Windows Server 2008 platform, does anyone have a suggestion as to what could be used to replace the MS WebControl? These are no budget, volunteer websites so I need something free.

Thanks for taking the time to read this. Any suggestions would be greatly appreciated.

IEWebControl and Terminal Server

If i run the application from a pc through the web server, the treeview is ok, if i connect through terminal server i have a problem.

TreeView problems: limited AutoPostBack / LinkButton in Node / multiple trees

anon2anon — Thu, 07 Aug 2003 11:51:47 GMT

hi folks,

I have some problems regarding the TreeView control.

1. When AutoPostBack is set to true, all events (Expand/Collapse/SelectedIndexChange) cause a postback. But I only want the event SelectedIndexChange to be posted back, because Expand and Collapse needn't be handled on server. What should I do to disable Expand/Collapse to be posted back?

2. Can I add LinkButtons or other Web Controls into a TreeNode? When the user select a TreeNode, I want a command to be issued, NOT a url to be opened. To do this, I tried to embed LinkButtons to TreeNodes but TreeNode isn't inherited from System.Web.UI.Control so I can't write code like this:

LinkButton button = new LinkButton();
... (configure the button)
TreeNode node = new TreeNode();
node.Controls.Add(button);

I think that if TreeNode inherits System.Web.UI.Control, it would be much more elegant than the current implementation.

3. there are multiple dynamically created TreeViews on a single page. When users select a TreeNode in one of these TreeViews, the event SelectedIndexChange only contains the index of new/old nodes, how could I know which TreeView the selected TreeNode belongs to?
If the event SelectedIndexChange also contains the ID of the selected TreeNode (but it doesn't), the problem can be solved easily.

btw: I had requested these new features in another post

Adding TreeNodes of TreeView Dynamically....

alecd — Sat, 29 Jan 2005 02:49:19 GMT

Hello everyone,

I've reached a dead end right now trying to get my TreeNodes to load dynamically.

I start by adding a base node as a starting point.



        Dim trnBase As New TreeNode


        trnBase.Text = "Search"


        tvw_Search.Nodes.Add(trnBase)

At this point there are no problems. trnBase has been added to tvw_Search. And the indexOf property of trnBase has been set to 0 (which will be used later in this subroutine).

Later on in this same subroutine I itterate through a DataTable containing my Nodes. Each itteration I check the ParentNodeIndex value. I then use that to get the ParentNode from the node collection of tvw_Search. Then I add the record as a node to the ParentNode.



        Dim intParentNodeIndex As Integer = drRow(4)





        Dim trnChildNode As New TreeNode


        trnChildNode.Text = drRow(7)





        Dim trnParentNode As New TreeNode


        trnParentNode = tvw_Search.Nodes.Item(intParentNodeIndex)


        trnParentNode.Nodes.Add(trnChildNode)

Now this is where I have trouble. The problem lies in the IndexOf property of the child nodes. When I added trnBase (the first set of code) trnBase gets assigned "IndexOf = 0". However, the nodes that are added via the Database (the second set of code) are not assigned an IndexOf value.

In other words, in my DataTable the first 5 records have "ParentIndexOf = 0". They are added to trnBase (indexOf = 0) no problem because trnBase was assigned an Index value of 0. The problem begins when I try to add nodes to these 5 new nodes. These 5 new nodes were never assigned an IndexOf value. Not only that, they aren't recognized in the tvw_Search nodes collection. When I do a "For each node in" tvw_Search, it only loops once for Node "trnBase", even though the first 5 records were added to "trnBase".

The only difference that could make any difference in my code is the last line in each set:



tvw_Search.Nodes.Add()





trnBase.Nodes.Add()

Is there something different I have to do as far as adding nodes to nodes to that of nodes to Trees?

Thank you for any help.

Error adding node - Specified argument was out of the range of valid values. Parameter name: Index was out of range. Must be non-negative and less than the size of the collection.

I have a recordset that I loop thru adding nodes to my treeview.

Well at around record # 123 out of 500 or so, I get this error adding child node :

"Specified argument was out of the range of valid values.
Parameter name: Index was out of range. Must be non-negative and less than the size of the collection."

The node I'm adding to exists, and I can't see anything wrong w/ the data - and it always gets hung up on the same record.

*And the same code has been used 122 times already w/out issue. *

Any ideas ? my code:

'lastDivisionIndex = 1

'lastOfficeIndex = 1.0

item = New TreeNode
        item.Text = dr("employee_name") 'value=Borek, Jeffry
        item.NodeData = dr("app_user_id") 'value=118
        tv1.Nodes(lastDivisionIndex).Nodes(lastOfficeIndex).Nodes.Add(item) 'error here, record 123 out of 500 records in recordset
        item = Nothing

IE WebControls ASP.Net 1.1

corsugus — Fri, 05 Dec 2008 09:44:16 GMT

Hello everybody, one question about a problem I have;

I downloaded the Internet Explorer Web Controls bundle and I built the Microsoft.Web.UI.WebControls.dll, I put the dll in the bin directory of my application and added the reference to my project. I added the TreeView control to the toolbar of my Visual Studio 2003 and I added the control to an .aspx page, everything appears to be correct in the designer but when I execute the application the TreeView doesn't render properly, I put the webctrl_client folder in the root directory of my IIS (5.1) and the TreeView still doesn't render properly.

I built the dll with the csc.exe compiler of the framework v1.1.4322, my IIS uses the ASP.NET v1.1.4322, my OS is Windows XP, my browser is ie 6.

A Workmate did the same process with the same configuration (I Think) and gets the TreeView rendering correctly.

Anyone has an idea about what is happening with my TreeView Control????, Thank you in advance for any answer.

Treeview control's selectednodeindex property in javascript

sphatak — Fri, 02 Dec 2005 21:10:16 GMT

I am trying to get the selectednodeindex property of the Microsoft Treeview webcontrol but having no luck. I am getting an error "undefined". Does that mean I cannot access this property using javascript? I want it in javascript to avoid postback. Is it possible to get the index of the node selected or the text selected in any other way on the client side?

Here is my javascript code snippet: alert(document.all.iform.TreeViewCtrl.SelectedNodeIndex)

Any help with me highly appreciated!

Thanks.
