Treeview Control

[Schoo]

I am successfully using the Microsoft.Web.UI.WebControls.dll but I can't get
the treeview control to run code when a node is selected. I read the msdn
online documentation and am doing this with code-behind in VB. Here is the
code that I am using:
===========================================
<ie:treeview runat="server" id="treeview1"
onselectedindexchanged="SelectedIndexChanged">
<ie:treenode ..../>
</ie.treeview>

Public sub SelectedIndexChanged(ByVal sender As Object, ByVal e As
TreeViewSelectEventArgs)
Label1.Text = "Selected " + e.NewNode.ToString + " (old Node index=" +
e.OldNode.ToString + ")"
End Sub
============================================
I need to fill a grid dynamically as a user clicks on an item. So, I need
an event that will respond and a way to use a key field so I can use that
information to pass to the grid. Any ideas or samples would be appreciated.

Hi, Schoo!
set Treeview autopostback=true

Public sub SelectedIndexChanged(ByVal sender As Object, ByVal e As
TreeViewSelectEventArgs)
Label1.Text
=Treeview.GetNodeFromIndex(Treeview.SelectedNodeIndex.ToString).Text
End Sub

Best Regards!

OK, you were right, I needed to set the autopostback property to true, but I
still can't get it to run the procedure. I can tell it is going back to the
server each time because I can see the page resetting, but I have a 'break'
set on the "Public Sub..." line of code and it is not stopping in debug
mode.

Here are the important code parts for your review:
====================================================
<ie:Treeview runat="server" id="Treeview1" AutoPostBack="True">
Also tried:
<ie:Treeview runat="server" id="Treeview1" AutoPostBack="True"
onselectedindexchanged="SelectedIndexChanged">

Public Sub mySelectChange(ByVal sender As Object, ByVal e As
TreeViewSelectEventArgs)
Label1.Text= .... <the code you had... it never gets here anyway>
End Sub
====================================================
Running the page, the treeview displays the simple XML file properly.

While we are working to get this 'click event' to work, I am going to start
working on the 'real' xml file that will actually be used. I noticed that
the sample does not provide key/index values from the dataset, but I will
need them for what I want to do. Basically I have to pass a GUID through
the treeview control from the dataset. Please let me know what you think
about how to do that.

Thanks,

Scott

Hi Schoo,

Thank you for posting in the community! My name is Jeffrey, and I will be
assisting you on this issue.
Based on the posts between you and ONIL, I think you meet the strange
problem that SelectedIndexChanged event does not firel

==========================================================
After review your code snippet, I found that you add your event handler
mySelectChange to SelectedIndexChanged event through code:
onselectedindexchanged="SelectedIndexChanged", I think you your event
handler's name is not correct, please try to use:
onselectedindexchanged="mySelectChange"

If your event handler still does not fire, I think you may set breakpoint
in Page_load to determine if postback occurs.

Also, you may try to add the event handler in the IDE.

The last possibility that I can think of is that maybe you initailized your
TreeView control programmaticly in Page_load, so when every postback, the
TreeView is re-initailized, so the SelectedIndexChanged event will not fire.

For your further XML logic, I am not sure if it related to your problem,
please apply my suggestion above and let me know if it helps resolve your
problem.
If it still does not work, please provide me more detailed information of
your web application.

=========================================================
Thank you for your patience and cooperation. If you have any questions or
concerns, please feel free to post it in the group. I am standing by to be

First, I put a page break on the Page_Load event and everytime I click on an
item in the treeview control, this event indeed does fire.

I tried a couple new combinations to call the procedure from the click event
of the control and none of them work to follow a click event. However, I
suppose I could use the Page_Load procedure to return data on the item
selected. That isn't really technically the correct way to do it and I
would prefer not to 'code around' issues like this.

Look, it's simple... I have a treeview control on a form. It uses an XML
file to populate it and I can see where that file may get pretty large. I
shouldn't have to post back to the server to put some text in a label
control from the treeview control, should I? Here is ALL THE CODE that I am
using, feel free to run this on your computer and tell me what is wrong, or
do a demo yourself and send me the code:

Schoo

Your aspx page says:
" <ie:TreeView runat="server" ID="Treeview1" AutoPostBack="True"

onselectedindexchanged="SelectedIndexChanged"> "

your code behind doesn't have "SelectedIndexChanged".
It has "TreeView1_SelectedIndexChanged"
Change one to match the other and it should work properly.

Hi Schoo,

Thanks for your feedback.
I feel strange that this event does not fire. I have tried your html code,
and added a breakpoint in SelectedIndexChange event handler.
This event does fire.

In my test I have removed all your xml related code and image url setting
code.
So I recommand you create a new empty project, then add a treeview control
onto the web form, then add the selecteditemchange event handler for it.
Then add a breakpoint in your selecteditemchange event handler to determine
if this event fires.

If it really does not fire, you can try to create a new C# project do the
same thing, to determine it this strange behavior happens again.

At last, if it does not fire, I think you can provide me your project to
reproduce this problem for me. I will try my best to help you.

Jeff,

Thanks for helping me with this. I did what you said and have the same
results. There is so little code that I wonder if this is some sort of a
configuration issue (global.asax) on my workstation. It is acting like it
just can't find the procedure when you click on an item in the tree. Here
is what I am doing... I hope you notice something I am doing wrong:

First I create a whole new web project in VS.NET with a VB back-end
I create a subfolder off the project called "XML" and drop in my XML file
I copy the Microsoft.Web.UI.WebControls.dll to the project's bin directory
I Rt. Click References, then "add reference" then browse to the project's
bin directory and select the Microsoft.Web.UI.WebControls.dll and click "OK"

I am not adding anything from the toolbar, I just add the following code to
the HTML tab in VS:
===================================================================
<%@ Page Language="vb" AutoEventWireup="false" Codebehind="WebForm1.aspx.vb"
Inherits="TreeviewTest.WebForm1"%>
<%@ Register TagPrefix="ie" Namespace="Microsoft.Web.UI.WebControls"
Assembly="Microsoft.Web.UI.WebControls" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">

<HEAD>
<title>HRReview</title>
<meta content="Microsoft Visual Studio .NET 7.1" name="GENERATOR">
<meta content="Visual Basic .NET 7.1" name="CODE_LANGUAGE">
<meta content="JavaScript" name="vs_defaultClientScript">
<meta content="http://schemas.microsoft.com/intellisense/ie5"
name="vs_targetSchema">
</HEAD>
<body MS_POSITIONING="GridLayout">
<form id="Form2" method="post" runat="server">
<ie:TreeView runat="server" ID="Treeview1" AutoPostBack="True"
onselectedindexchanged="SelectedIndexChanged">
<ie:TreeNode Expandable="CheckOnce" Expanded="True" Text="North America"
TreeNodeSrc="XML/employeetree.xml"></ie:TreeNode>
</ie:TreeView>
<asp:Label id="Label1" style="Z-INDEX: 101; LEFT: 400px; POSITION:
absolute; TOP: 32px" runat="server"
Width="232px" Height="80px">Label</asp:Label>
</form>
</body>
</HTML>
===================================================================

Then I add some code to my 'code-behind' so it looks like this:
===================================================================
Imports System.Data.SqlClient
Imports Microsoft.Web.UI.WebControls
Public Class WebForm1
Inherits System.Web.UI.Page

#Region " Web Form Designer Generated Code "

'This call is required by the Web Form Designer.
<System.Diagnostics.DebuggerStepThrough()> Private Sub
InitializeComponent()

End Sub
Protected WithEvents Label1 As System.Web.UI.WebControls.Label
Protected WithEvents Treeview1 As Microsoft.Web.UI.WebControls.TreeView

'NOTE: The following placeholder declaration is required by the Web Form
Designer.
'Do not delete or move it.
Private designerPlaceholderDeclaration As System.Object

Private Sub Page_Init(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Init
'CODEGEN: This method call is required by the Web Form Designer
'Do not modify it using the code editor.
InitializeComponent()
End Sub

#End Region

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
End Sub
Public Sub SelectedIndexChanged(ByVal sender As Object, ByVal e As
TreeViewSelectEventArgs)
Label1.Text =
Treeview1.GetNodeFromIndex(Treeview1.SelectedNodeIndex.ToString).Text
End Sub
End Class
===================================================================

When I run it, it shows the XML data fine, but will not get to the
SelectedIndexChanged procedure (which I have a stop set on)

Also: Can I add "key" elements to the XML file data to get key values into
the control? Or is there another way to pass index/key values that can be
passed when the user clicks on the control?

I hope this all helps. My deadline to get this done is by the end of the
month... so I still have a little time.

[Schoo]

Once you told me to open the combo boxes to build the procedure I had a good
feeling about getting this right and sure enough, once I did that everything
worked fine. I hand-typed in the procedure code from an example which was
not good enough. Now it works fine. Thank you.

Now that I have the procedure firing, is there a way to link a 'key' to the
tree control? I am basically making a company tree of employees and each
employee has an associated ID number in the database. I can easily dump
this to an XML file but I would like to show the names and pass the ID
number. Here is a sample of my XML file:

<TREENODES>
<treenode text = "Joe Blow"
</treenode>
<treenode text = "Jane Doe"
</treenode>
</TREENODES>

Can I just add in a 'key' element or something? What code should I write in
my 'index changed' procedure to return the key from the item?

Thank you for getting me this far, I hope you can help me with this
additional issue.

Schoo

 

[Jeffrey Tan[MSFT]]

Hi Schoo,

I am glad it finally works,

For your further concern, I think you should refer to TreeNode's NodeData
property. It gives you a place to store node specific data.
So you can do like this:
Private Sub TreeView1_SelectedIndexChange(ByVal sender As Object, ByVal
e As Microsoft.Web.UI.WebControls.TreeViewSelectEventArgs) Handles
TreeView1.SelectedIndexChange
Dim tn As TreeNode =
TreeView1.GetNodeFromIndex(TreeView1.SelectedNodeIndex)
Response.Write(tn.NodeData)
End Sub

For document reference about TreeView control, please refer to:
http://msdn.microsoft.com/library/default.asp?url=/workshop/webcontrols/refe
rence/treeview_entry.asp

Please apply my suggestion above and let me know if it helps resolve your
problem.

Thank you for your patience and cooperation. If you have any questions or
concerns, please feel free to post it in the group. I am standing by to be
of assistance.
Have a nice day!!

[Schoo]

Thank you for the information. I will be sure to research what you
mentioned.

Now that I have this working I have a problem I didn't anticipate: because
the tree can be expanded so large (tall), it is causing a problem on the
screen. I need the control to be restricted in height and allow the user to
vertically scroll the items (much like the tree in file explorer). I have
been playing with CSS to try to create a container to do this but so far not
having any luck. I have also been playing with frames but this causes other
issues. Is there a way to limit the control vertically and allow the user
to scroll the control?

Schoo

 

[Schoo]

Nevermind... I set the treeview property 'width' and 'height' to values and
I see that it does restrict it the way I wanted.

Is there a page on msdn that shows the properties of this control? ie.
<ie:treeview item1="setting" item2="setting".... n... >

I am looking for documentation on the 'items' above. Unlike other controls
in VS.NET, these are not automatically coming up as I type (intellitype).

Schoo

 

[Schoo]

I modified my XML file so that I have an extra attribute in the elements
now:

<treenode text="Joe Blow" idEmp="12345">

I did this after looking closely at the "About the TreeView WebControl" at
msdn, but I don't see how you relay this value to the procedure. I guess I
am looking for something like this:

label1.text = Treeview1.GetNodeFromIndex(Treeview1.SelectedNode("idEmp"))

The above line doesn't work of course, but that is what I am thinking...
sorry... I'm a ADO guy and I think that way out of habit! It seems like I
am thinking of this in the wrong way.

The msdn explaination also makes it look like I might have to write XSL to
identify the attribute as a node ("Data Binding with XML and XSL Templates"
section). Is that necessary?

An example would be great!

Schoo

 

[Jeffrey Tan[MSFT]]

Hi Schoo,

Thanks for your feedback.

I have seen 3 posts of you, based on the time you posted, I think you have
figured out some of the problems yourself.

I suppose your now conern is the "popup code helper document" in HTML
desinger in Visual Studio.Net for treeview control.
=========================================================
Actually, the "popup code helper document" in Visual Studio.Net is called
"intellisense", which is a powerful design-time support in Visual
Studio.Net.
Noramlly, in code editor the design-time intellisense support is available,
but in HTML view desinger, you will find the treeview control's
intellisense is un-available.

The html designer intellisense is supported through XML schema. All the
server controls' intellisense supports is stored in C:\Program
Files\Microsoft Visual Studio .NET\Common7\Packages\schemas\xml\asp.xsd

To add your own design-time support for treeview control, you should write
the schema yourself.

For more information about customize html intellisense support, please
refer to the article below:

Jeffrey,

Thank you for your reply. I will take a look at writing that code to do the
intellisense feature. Could you please take a look at the string that talks
about passing a key/index value through the prodcedure? This is the last
piece I need to finish this project.

I also started a new thread in this newsgroup with that specific topic.

Thanks,

Scott
