Populate Listview File From Accompanying TreeView Of Directories

Jul 20, 2009

This is a follow-up questions to the following post: [URL]

Below (Example 2) is working code for populating a treeview with directories only down to 1 level. Note just directores are added- No files. I want to add a Listview control beside my treeview and have the Listview populated with the "files" from the selected node in the treeview. This would fire off the NodeMouseClick event of the treeView. I have used Example 1 (NodeMouseClick) before with other code that I have. However, I cannot get the code to work with the Example 2 code below

how to change the Example 1 code to work with Example 2?

Example 1
'************************************************
Private Sub treeView1_NodeMouseClick(ByVal sender As Object, _
ByVal e As TreeNodeMouseClickEventArgs) _

Use A Treeview XML File To Populate Buttons?

Jul 9, 2012

The treeview system I am using is by Andy Bonner from the following Link, as advised I have created a new post.[url]...

Andy you were asking what it is I am trying to do so I will try explain it a little better. The treeview system you have created allows me to import / edit and save XML files based on the treeview structure that I create. What I now want to do is use the same XML files to populate buttons on a form.

So for example if I have 10 buttons on a form then on load it will look at the xml file and change the text of the buttons to whatever the main level of the treeview is.[code]...

Add All Files And Sub-directories To A Treeview Control?

May 20, 2009

I am using the following code to add all files and sub-directories to a Treeview control. The user can select a directory (using a folder browser dialog) and this code will add that directory, and all it's files and sub-directories, to the Treeview:

[Code]....

I have tried a few ways, mainly 'copying' the code from this recent codebank submission. However, I keep getting the obvious cross-thread call issue that I am adding nodes to the 'node' parameter, which is not allowed.

I am at a loss at how to do this otherwise. How can I update a Treeview like this if I have to recursively add nodes to the 'node' parameter, which is not 'available' in a separate thread?

VS 2010 Populate Multi-column Listview From File?

Jun 14, 2011

I am trying to populate a multi-column listview from a file. I have gotten as far as reading the correct data from the file to an array and populating the correct columns with said data. However, sometimes the array will span multiple lines of data in the file and I need all of these matches to populate the listview but the code that I have now only populates the listview with the data from the first matching line. I have tried declaring the variables as listviewitems instead of strings, which allowed me to use listView.Items.AddRange(arr) but then all of the data appeared in the first column instead of spread across all columns like it is supposed to. At this point I am at a loss because I can only figure out how to either fill the first column with all data or fill all columns with only the first line of data. Here is the code that I have

[Code]...

It is really only the last part of the If.. Then statement that I need help with. I was thinking that a loop would accomplish what I am trying but I am still pretty new to VB and do not know the correct code.

Form With A Treeview And A Listview - When Deleting Multiple Files A Confirmation Message Box Pops Up For Each File Selected

Oct 27, 2009

I have a form with a treeview and a listview. The treeview lists the folders on your system and listview shows the files in the selected folder, similar to windows explorer. I have a delete button for deleting files.

Dim i As Integer
For i = 0 To lv1.SelectedItems.Count - 1
Dim csi As CShItem = lv1.SelectedItems(i).Tag

[CODE]...

When deleting multiple files a confirmation message box pops up for each file selected. I would like to have it come up once and ask 'Are you sure you want to send these 'x' files to the recycle bin?' where 'x' is the number of files selected.

Populate TreeView Via XML/DataSet

Feb 21, 2011

This is a problem I have been trying to conquer for some time now and haven't managed to deal with. I've looked pretty hard on Google and so on, but most of what I find there is for populating a TreeView from a database. The closest I got was a bit of C# code for populating with a list of file paths. But unfortunately the result is individual roots & branches for each item.

What I'm working on is a message template tool where I'm trying to get the nodes in the treeview, which represents the templates, to populate from an XML file. I'm using DataSets for their simplicity of working with XML. Here's a basic example of the structure of the XML which is imported to the DataSet;

Code:
<?xml version="1.0" standalone="yes"?>
<Templates>
<Item>

[Code].....

So the path to each node will look like RootBranchName. I know this will no doubt require some recursion, but recursion is one thing I haven't fully grasped yet.

Silverlight TreeView Wont Populate?

Feb 9, 2011

I am trying to populate a TreeView in silverlight, but I am having some difficulties - it always appears empty.I found a good tutorial (here) on how to do it, I created a new project and copied the code as it appears, using C#, and it worked perfectly. I have now tried to incorporate it into my project (which uses VB), but It doesnt work. My VB code is as follows:

XAML

<UserControl.Resources>
<common:HierarchicalDataTemplate x:Key="myHierarchicalTemplate" ItemsSource="{Binding Items}" >
<TextBlock Text="{Binding myString}" />[code]....

Edit: I have tried debugging the project, and the "itemsSource" collection appears to be generating correctly, a Is it a display binding issue?
