May 21, 2012
I have a repeater control with item template like this:
<ItemTemplate>
<table width="70%">
<tr id="rowSIC" runat="server">
<td width="10%">
[code]....
I have a treeview on this page of which each node has and Id and value. on selected node change event, I want to change the text of repeater selected node. I am writing code like this:
Protected Sub TreeView1_SelectedNodeChanged(sender As Object, e As System.EventArgs) Handles TreeView1.SelectedNodeChanged
Dim EmployeeRepeater As Repeater = CType(Me.Form.Controls(1).FindControl("Repeater1"), Repeater)
Dim EmployeeRepeaterItem As RepeaterItem
[code]....
But It is not chagging MyLabel text. How to fix it ? Both treeview and repeater are populated in !Page.Ispostback event?

I have this code to select first node of TreeView. But when page loads the by default root node is other than first, I want to set the selected node as top most by default. Here is my code in page load but it's not working:
Dim nodes As TreeNodeCollection = TreeView1.Nodes
If nodes.Count > 0 Then
' Select the root node
TreeView1.SelectedNode = nodes(0)
End If
This gives the blue underline error on this line:TreeView1.SelectedNode = nodes(0)
The error is: "Selected Node Property is read Only"

for some reason I have to click a node in a treeview twice for it to register as selected. I've checked with treenode.isselected() and treeview.selectednode() and with both two clicks is required to show the selected node (1 click continues showing the previously selected node as selected) while the visual highlight/selection works perfectly with 1 click. Any suggestions on what may be wrong/how it could be fixed? (The node selection code is in the nodeclick event)

I have a treeview control where I am dynamically selecting a node depending on user interaction. when a node is selected I want to be able to have the scrollbar go to the location of that selected node in the tree. The scrollbar is simply made by overflow:auto in the div tag where the treeview is located. Can someone give me some detailed code to accomplish this?

I have been playing with, and researching, this all day and can't figure it out. I have a Windows Explorer style form with a TreeView and a ListView. I've populated the TreeView with directories and when a node is selected, the ListView fills with the contents of the directory associated with that node. No problem there, but I want to be able to select a directory in the ListView and automatically select the associated node in the TreeView, just like it works in Windows Explorer. All the information I've found online tells me how to populate the ListView from the TreeView, but I haven't found any good examples of how to populate the TreeView from the ListView.

1. I need to be able to store the STR MG INT and SPD somewhere when they create an item and make sure it is assigned to that item, and since I allow them to create unlimited item, I need this way to be dynamic (as in create variables as needed).
2. I need to find some way to make sure the user has selected an item name in the treeview (not type or main node).For example, they need to click Hockey Mask and then click the equip item button for it to work?

Ok, so I know I have to change the labeledit to true but that doesn't change the selected node to be able to edit, so how does that work?
Along with renaming I have it set to that a user can add a node. So once the node has ben added how do I let them rename it as it is being added and without being a prompt or inputbox? So lets say I cam clicked on a parent and they click add node, it adds it to parent but I have it so it is default "New" but I want them to edit it as it is added. I think it will be along the same lines as clicking on one and rename but I have to start some place.

You wouldn't think so, but it does when the listbox is bound to a datasource (as far as I can see).
I've reduced the behaviour to the code below. The "if" line toggles between loading a list via data binding and loading a list "manually" (both use the same data table). In each case I set the selected index afterwards, and then change the parent form. With manual loading, the selected index is retained, with binding it is lost. I cannot see how this makes any sense - I don't see why changing the host form should alter any property of the list. Is this a bug?
Public Class Form1
Sub main() Handles Me.Load
Dim ListControl1 As ListBox = New ListBox

i want to add a node just above all removable drives from the thread I asked about in before. I decided that I don't want to have "C:" as a node, instead I just want my program to be the node. I've worked with this before but i can't figure it out without messing up what I already have.

All my TreeView nodes have a unique ID for their Node Depth.
I want to set Checked=True on the TreeView Node which matches a certain value.
Currently I'm doing the following:Dim value As Integer = 57
For Each n As TreeNode In tvForces.Nodes
If n.Value = value Then n.Checked = True
Next
Is there a better way of finding the Node which I want to set as Checked=True rather than looping through each node?
I'm looking for something like:Dim value As Integer = 57
n.FindNodesByValue(value)(0).Checked = True
Is there anything like this that I can use?

I have a TreeView in my form that I populate manually from a list of items in a database. The descriptions of the TreeView items causes a horizontal scrollbar to be displayed. That is fine except that it seems that this scrollbar hides the item at the bottom of the TreeView. If I expand a tree node the bottom item that was previously hidden will be displayed.
