listbox

I am using WPF and C# I have a button that opens a window, which also includes a button that adds an User object item to a listbox and I want the listbox index to be updated after insertion. I understood that the solution is about using observable class of INotifyCollectionChanged but actually I dont know how and where to use them. Can you help me on determining what and where to implement, register, fire etc. Edit: I succeeded this by Quartermeister's help where my User object is collected in a list, but now I want to do the same thing where my object is collected in a dictionary The easiest

I spent last two weeks trying to figure out a method to display the items of a listbox in reversed order without using any sort property and without putting any presentation logic in my entities, I just want that the last inserted item is displayed at the top of the listbox. The only pure XAML solution I've found is this WPF reverse ListView but it isn't so elegant. I've also tried to override the GetEnumerator() of my BindableCollection (I use Caliburn Micro as MVVM framework) to return an enumerator that iterate over my collection's items in the reverse order but id did not work. How can I

I'm writing a VB Macro to do some processing of documents for my work. The lines of text are searched and the bracketed text is put in a list(box).

(as a result I now have a document with 32 links - all empty except for 3 I put in myself -

I have a problem with my ListBox in WPF. First of all, I have a horizontal ListBox with custom ItemTemplate. Now, I want to stretch the items, so that the items fits over the complete width of the ListBox. I tried things like setting the HorizontalContentAlignment to Stretch , but this still not working. Here is my ItemTemplate : <DataTemplate x:Key="ListViewStepTemplate"> <Grid VerticalAlignment="Stretch"> <TextBlock Text="{Binding Path=Title}" FontSize="15" HorizontalAlignment="Center" VerticalAlignment="Center" /> <Image Height="16" Width="16" HorizontalAlignment="Right" VerticalAlignment=

I have the following: <ListBox SelectedItem="{Binding SelectedItem}" ItemsSource="{Binding items}" DisplayMemberPath="s"/> <TextBlock Text="{Binding SelectedItem.s}"/> This is definition of SelectedItem public MemEntity SelectedItem {get; set;} MemEntity is a class containing public String s {get; get;}. Basically, I want s of the selected item to be shown in the TextBlock (same property as shown in ListBox ). This doesn't work, so what am I doing wrong? Try this, <TextBlock ... Text="{Binding ElementName=items, Path=SelectedItem.s}" /> then add a name to your ListBox as, <ListBox x:Name=
