I'm customising the appearance of grouping in a ListBox. In ListBox.Resources, I have declared something like (formatting removed): <Style TargetType="{x:Type GroupItem}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type GroupItem}"> <StackPanel Orientation="Vertical"> <!-- ...
I have a text box where I want to limit the number of selected items to MaxSelection. The desired behaviour is that once MaxSelection items are selected any futher selections are ignored. (Thus this question is different from "limit selections in a listbox in vb.net"). I have an event handler for the SelectedIndexChanged event for the...

I have a collection of ViewModels bound to a ListBox. I am trying to bind the IsSelected properties of each together. In WPF it works by setting the style: <Style TargetType="{x:Type ListBoxItem}"> <Setter Property="IsSelected" Value="{Binding Path=IsSelected, Mode=TwoWay}" /> </Style> This does not work in Silverlight. How can I...
In .NET there doesn't seem to be a property to find the item just selected in a multi-select listbox; SelectedIndex always shows the first selected item. From memory VB6 had the ListIndex property that changed accordingly... Why remove a useful property ?! Duplicate: How to get the last selected item in multiselect ListBox? ...

On my WinForm, I bound my listbox to a Table in Entity on EDMX, but when the table data is changed, I tried to call myListBox.DataSource = Entities.table; myListBox.ResetBindings(); myListBox.Refresh(); but nothing happens in ListBox. The Entities.table object holds the right data though, it just doesn't reflect on the ListBox. Any ...
I have a ListBox, that's bound to an ObservableCollection. Each ListBoxItem is displayed with a DataTemplate. I have a button in my DataTemplate, that when clicked, needs a reference to the member of the ObservableCollection it's part of the DataTemplate for. I can't use the ListBox.SelectedItem property because the item does not become...
Hi How can I display a preview (almost like a hint) of an image when I hover the mouse over an item in a listbox of filenames? I've tried showing a form and loading the image, but when the preview form shows, I lose focus for the listbox which means that when I move the mouse, the preview image does not change when I go to the next item...

The image below shows how my code works. When I press button2 the listbox is updated, but not when I press button1. Why? Is the problem threading related? If it is, where should I add the call to (Begin)Invoke? One interesting thing to note is that if I first press button1 and then button2 the data generated by the button1 click is s...
I've got a ListBox which is getting new items added to it through Databinding (i.e. something is getting added to the list and the box is updating to include the new item). The items in the list box are editable data templates, so the question is: How do I set the focus to the first field in the template when a new item is added? I've ...

This is similar to a question I asked a couple of days ago. However, I now have a better understanding of the problem, so I'd like to take another crack at it. I am creating an MVVM app that (among other things) displays a list box with alerts for the user. These alerts relate to various routine tasks that have to be carried out periodi...
