listbox

My scenario is this: I have two listbox's, one that contains all my database items, and an empty one. The user adds the items needed from the full listbox to the empty listbox. I'm using a form to submit all the items the user has added. The problem is, only the selected items from the listbox are submitted. So if the user deselects some of the items, they wont be submitted in the form. My view looks like so: <% using (Html.BeginForm("MyAction", "MyController")) { %> <%= Html.ListBox("AddedItems", Model.Items)%> <input type="submit" value="Submit" name="SubmitButton"/> <% } %> My Controller

I have a listBox1 object and it contains some items. I have a button to move selected item up and another to move selected item down. What should the code be to the two buttons? private void UpClick() { // only if the first item isn't the current one if(listBox1.ListIndex > 0) { // add a duplicate item up in the listbox listBox1.AddItem(listBox1.Text, listBox1.ListIndex - 1); // make it the current item listBox1.ListIndex = (listBox1.ListIndex - 2); // delete the old occurrence of this item listBox1.RemoveItem(listBox1.ListIndex + 2); } } private void DownClick() { // only if the last item isn

I have created the fallowing ListBox : <ListBox x:Name="RecentItemsListBox" Grid.Row="1" BorderThickness="0" Margin="2,0,0,0" SelectionChanged="RecentItemsListBox_SelectionChanged"> <ListBox.Resources> <Style TargetType="{x:Type ListBoxItem}" BasedOn="{StaticResource {x:Type ListBoxItem}}"> <Style.Triggers> <!--This trigger is needed, because RelativeSource binding can only succeeds if the current ListBoxItem is already connected to its visual parent--> <Trigger Property="IsVisible" Value="True"> <Setter Property="HorizontalContentAlignment" Value="{Binding Path=HorizontalContentAlignment,

If I have a list of strings, eg: List<string> MyList = new List<string>(); MyList.Add("HELLO"); MyList.Add("WORLD"); Is there an easy way to populate a ListBox using the contents of MyList? Adriaan Stander Try : List<string> MyList = new List<string>(); MyList.Add("HELLO"); MyList.Add("WORLD"); listBox1.DataSource = MyList; Have a look at ListControl.DataSource Property You can also use the AddRange method listBox1.Items.AddRange(myList.ToArray()); Is this what you are looking for: myListBox.DataSource = MyList; This also could be easiest way to add items in ListBox. for (int i = 0; i < MyList

In my application, I have a ListBox with items. The application is written in WPF. How can I scroll automatically to the last added item? I want the ScrollViewer to be moved to the end of the list when new item has been added. Is there any event like ItemsChanged ? (I don't want to use the SelectionChanged event) Oz Mayt Try this: lstBox.SelectedIndex = lstBox.Items.Count -1; lstBox.ScrollIntoView(lstBox.SelectedItem) ; In your MainWindow, this will select and focus on last item on the list! The easiest way to do this: if (VisualTreeHelper.GetChildrenCount(listView) > 0) { Border border =

I am working on a news feed. This will update every so often and if new items are found, I want to slide in the new content from the top. Right now, I am just having it fade in by doing the following: <ListBox Grid.Row="0" Height="Auto" HorizontalAlignment="Stretch" Margin="5,5,5,5" VerticalAlignment="Top" ItemsSource="{Binding NewsItems,UpdateSourceTrigger=PropertyChanged}" > <ListBox.ItemContainerStyle> <Style TargetType="{x:Type ListBoxItem}"> <Style.Triggers> <EventTrigger RoutedEvent="Loaded"> <EventTrigger.Actions> <BeginStoryboard> <Storyboard> <DoubleAnimation Storyboard.TargetProperty
