.net - Create A Two-way Link The SelectedItem Property Of A ListView?
Oct 6, 2010
I've recently taken over a MVVM project started by someone who's now left the company; It's my first time using WPF, but by the looks of it, it was his first time using both WPF and OOP...Anyway, I've got a ListView in the XAML, and I've got a collection class which doesn't currently contain a "SelectedItem" property.what code I need to put in to link the SelectedItem of the ListView to the as-yet-unwritten SelectedItem property of my collection, and then what code I need to put in so that the SelectedItem of the collection links back to the ListView?

How to override the SelectedItem property? When you look at the description of the SelectedItem property, the description shows as:"Gets the selected item with the lowest index in the list control". I would like to bypass the "lowest index" portion of the property...I have multiple items in the same list with the same value, but different text. I just want to set the SelectedItem to the actual item I've selected, not one with the same value that appears earlier in the list...

I'untangle a particularly malodorous collection of spaghetti code. Anyway, I have the following XAML code:
<UserControl.Resources>
<CollectionViewSource x:Key="XMLObjectGroups" Source="{Binding Path=XMLObjectList}">
<CollectionViewSource.GroupDescriptions>
<PropertyGroupDescription PropertyName="IsDateType"/>
[code].....
On the second line XMLObjectList is a readonly property of a ViewModel class, returning a Collections.ObjectModel.ReadOnlyObservableCollection(Of MyOrder).On the final line SelectedOrder is a property of the same ViewModel class, which allows setting and getting of a MyOrder object.
I have confirmed that XMLObjectList is being correctly referenced by renaming the property, mistyping the string, breakpoints, etc. XMLObjectList definitely references the XMLObjectList property of this particular ViewModel class.The SelectedOrder property, however, is never accessed at runtime, meaning that it isn't properly hooked up to the SelectedItem of this ListView.

Why the error occurs for the following
Private Sub LVW_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LVW.SelectedIndexChanged
txtTAID.Text = LVW.SelectedItems(0).Text
txtVNO.Text = LVW.SelectedItems(0).SubItems(1).Text[code]....

My question is, the SelectedItem property of the Combobox is supposed to return a integer value, is it not? Because I am getting back integers, sometimes, then the next time through I get back a String. Has anyone else had a problem like this with the Combobox?

A ListView (or ListBox) with following properties:
<ListView SelectionMode="Single">
<sys:String>James</sys:String>
<sys:String>Claude</sys:String>
[Code]....
will result in selecting two items simultaneously if I click on "James", even though I chose SelectionMode="Single". It's even the same behaviour when I use a helper class with a string-property to display in the ListView. It seems like the ListView is evaluating the Items and selecting those which are Equal() rather than ReferenceEqual(). Is there a way to change this behaviour so that the ListView treats every item individually?

Working on a project that contains a listView (populated from a database already) and several textboxes. What I am trying to do, and cannot figure out, is to program this so that when a user makes a selection in the listview, it hits a specific database, and based on certain values within that databse, the textboxes are populated with things such as name and address, etc..

This problem refers to VB 2008. My ListView Property is named lvSummary, View is set to Details, 2 columns are defined, and this is the code is being called when I click on the menu Summary item:
Private Sub mnuSummary_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles mnuSummary.Click
Summary.ShowDialog()
Summary.lvSummary.Items.Clear()
[code]....
The problem is that when I click on the Summary menu item the first time, the numbers "1" and "2" do not appear in the listview columns. I then close the window by clicking on the OK button, then immediately click on the Summary menu item again, and this time the numbers DO appear! What am I doing wrong to cause these numbers to not appear the first time?

I'm trying to create a Window with a ListView and an Area where details to the selected Object are displayed. The Listview displays items stored in an ObservableCollection(Of T) Collection. The items itself contain also an ObservableCollecton(Of T) Collection which should then be displayed in the details area in another ListView, accordingly to the selected item of the first ListView.
The Problem: The InitializeComponent() throws an Exception (XAMLParseException).
Exception:Set property 'System.Windows.Controls.GridViewColumn.DisplayMemberBinding' threw an exception.
InnerException:Object of type 'System.String' cannot be converted to type 'System.Windows.Data.BindingBase'.
The Line- and ColumNumer of the Exception are Pointing at the <GridView> of my ListView (.View).This is the First ListView
<ListView ItemsSource="{Binding Path=MyObjectCollection, Mode=OneWay}" SelectedItem="{Binding Path=Selected, Mode=OneWayToSource}">
<ListView.View>[code]....
So. How can I bind to the Collection Property of an Object could be nothing?

I've got this code which basically loops through a set of folders and subfolders and finds specific file types. And then lists these in a listview. Now, it's intended to list exe and msi files. And I've made it so that these icons can be doubleclicked after they have been listed. I do this by adding the path to the file in it's tag property.
But, my superiors want a checkbox next to each item. So that they can check each item they want installed. And then have a button which runs the path in each tag property one at a time. It's basically the part where I fill the listview with the checkbox, filename of the exe or msi file, tag and the icon that I'm wondering about.
This is the existing code. This includes just a Tile view of the listview. Public Sub getDirectories(ByVal strFilepath As String, ByVal strFileExtension As String, ByVal objControl As Object)
'Load first files from the root folder. Then loop each subfolder
Dim di As New DirectoryInfo(strFilepath)
Dim aryFi As IO.FileInfo() = di.GetFiles(strFileExtension, SearchOption.AllDirectories)
[Code]...
But there should be a way of combining these two right? I'm not sure how I can add a checkbox in the first column of the listview? I've already set the Checkbox property of the listview to True. But I could use some pointers here if anyone's got any. :)
