listbox

I am in a big trouble. I read 4 stackoverflow question and one blogpost. I have tried 5 different approach to view the selected items in a multiple selectlist. I have no success. The multiple selectlist is generated, but it does not select the items. I have no more idea. Model : public class EditableModel { public IList<Company> SelectedCompanies { get; set; } public IList<SelectListItem> SelectListCompanies { get; set; } } Controller : public ActionResult Edit(int id) { var service = _serviceDAL.GetEditableModel(id); if (service!= null) { service.SelectListCompanies = GetSelectListCompanies

If I put a DataTrigger in a simple Listbox I get this runtime exception: Items collection must be empty before using ItemsSource My listbox without datatrigger (no exception): <ListBox ItemsSource="{Binding EdgedBoards}" SelectedItem="{Binding SelEdgedBoard, Mode=TwoWay}" DisplayMemberPath="Name"> <ListBox.ItemContainerStyle> <Style TargetType="{x:Type ListBoxItem}" BasedOn="{StaticResource {x:Type ListBoxItem}}"> <Setter Property="IsSelected" Value="{Binding IsSelected, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" /> </Style> </ListBox.ItemContainerStyle> </ListBox> My ListBox with

I have set Interaction.Triggers to ListBox and perform respective TargetedTriggerAction when 'SelectionChanged' event occurs, like below. <ListBox x:Name="WorksheetListBox" ItemsSource="{Binding WorkSheetCollection}" ItemTemplate="{StaticResource workSheetTemplate}"> <i:Interaction.Triggers> <i:EventTrigger EventName="SelectionChanged"> <action:WorksheetListBoxAction /> </i:EventTrigger> </i:Interaction.Triggers> </ListBox> But my requirement is I need to set Interaction.Triggers to ListBoxItem's 'PreviewMouseDown' event(Note: ListBox populated via ItemsSource) You can try something like this:

I have a ListBox inside a HubSection, whose Items are bound to a class "players" added to my DefaulViewModel via code behind. First I simply put a TextBox bound to the property "PlayerName" of my class "players". Now I would like to add a ComboBox with some items that are NOT part of the class players. Is it possible ? I thought that definind an ItemsSource in the ComboBox would sort of override the ItemsSource of the ListBox, but nothing displays. The DataContext of the whole page is defined like so: DataContext="{Binding DefaultViewModel, RelativeSource={RelativeSource Self}}" Then the

I have two classes(forms), and I would like an item from class2 to be added to listBox in class1 when I click "Accept" button. I tried with the following code, but nothing changes in the listBox: private void button1_Click(object sender, EventArgs e) { CarRental i = new CarRental(); string id = idRental.Text.ToString(); i.listBox1.Items.Add(id); i.listBox1.Update(); this.Close(); } Where did I make the mistake? Declare RentalId property on Form2 . And at CarRental form (your first form) do following: using(Form2 form2 = new Form2()) { if (fomr2.ShowDialog() != DialogResult.OK) return; listBox

I have a ListBox with Foo objects, and based on some events I disable/enable the ListBoxItems in the ListBox. Using the ListBox.Items property I find Foo objects, and from what I've understood I need to use the following function to get the ListBoxItem container for the Foo. Correct? foreach (var item in Items) { var lbi = ItemContainerGenerator.ContainerFromItem(foo) as ListBoxItem; // do something } Actually I have a custom control FilteringListBox which inherit ListBox and adds an extra property to it. The above code is in the code behind of the custom control and works just fine when the
