SelectedIndexChange event is not working in Microsoft.Web.UI.WebControls treeview

I'm using a Microsoft.Web.UI.WebControls treeview in my web application (ASP.NET 1.1). It is working fine and i have built a tree with data.

Now i need to load some pages according to the node which user clicks.

I'm not able to get selected node details. There's a event called "SelectedIndexChange". But it is not firing properly when i clicked on tree nodes.

Any one over there who used it??? or any ideas???

Thank you very much in advance..

Hi,
I am also doing R&D on TreeView but could notdo in ASP.NET1.1.How did u do.Please tell.
I will do and then I can check ur problem.
Thanks

As far as I know, .NET 1.1 doesn't have a System.Web.UI.WebControls.TreeView Class, this class was first added to the FrameWork in .NET 2.0

So, either you're using .NET 2.0, or you're using another TreeView control (which might be from Microsoft itself as well, I vaguely remember they had some TreeView Control on www.asp.net before)

Please specify which TreeView you use, so that we can try to help you in an efficient way.

hi
thank you very much for replying my post.
yes .NET 2.0 only have the in built web tree view control

I’ll brief u my problem. so then both of u can get a idea what i have been doing.

I’m developing a web application using ASP.NET 1.1(VB). Since there is no inbuilt tree view component for web applications in .NET 1.1 I’m using Microsoft.Web.UI.WebControls.TreeView control. I have successfully bound data which retrieved from database. Now I need to do an operation (display another set of data in a separate grid) based on the tree node which user selects. So I have written my code for SelectedIndexChanged. My problem is this event is not firing properly.


This is my aspx file.

<iewc:treeview id="trvCategory" runat="server" AutoPostBack=true>

<iewc:TreeNode Text="Category" Expanded="true" />

</iewc:treeview>

This is my Page_Load

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

If Not Page.IsPostBack Then

LoadTree()

End If

End Sub


And This is my SelectIndexChanged event

Public Sub trvCategory_SelectedIndexChange(ByVal sender As Object, ByVal e As Microsoft.Web.UI.WebControls.TreeViewSelectEventAr gs) Handles trvCategory.SelectedIndexChange

‘MY CODE

End Sub


I have tried all following methods too.

I found that I should create handler separately so I add following line in page_load

AddHandler trvCategory.SelectedIndexChange, AddressOf trvCategory_SelectedIndexChange

And in another article asked to do above in InitializeComponent

And I have done following as well

<iewc:treeview id=" trvCategory " runat="server" onSelectedIndexChanged="trvCategory_SelectedIndexChange" AutoPostBack=true>

<iewc:TreeNode Text="Category" Expanded="true" />

</iewc:treeview>


But none of these are working.

If u can give me a solution that’ll be a great help

Thank you very much
