listbox

If hold the listbox, I want to get listbox index. This is my code: <ListBox Margin="0,0,-12,0" Hold="holdlistbox" x:Name="listbox" SelectionChanged="listbox_SelectionChanged" SelectedIndex="-1"> </ListBox> private void holdlistbox(object sender, System.Windows.Input.GestureEventArgs e) { //How to get ListBox index here } If anyone knows help me to do this. e.OriginalSource will get you the actual control that was held (the top-most control directly under your finger). Depending on your ItemTemplate and where you hold then this could be any of the controls in the item. You can then check the

The ListBox control does not implement a Command property. I have to attach some functionality to the SelectionChanged event. Somebody knows how can I do it? Please help me I prefer using a binding to the SelectedItem and implementing any functionality in the setting of the binding property. <ListBox ItemsSource="{Binding Items}" SelectedItem="{Binding SelectedItem}" /> ... public class ViewModel { public IEnumerable<Item> Items { get; set; } private Item selectedItem; public Item SelectedItem { get { return selectedItem; } set { if (selectedItem == value) return; selectedItem = value; // Do

This is the ListBox code: <ListBox x:Name="courseslistview" ItemsSource="{Binding .}" FontSize="18.667" FontFamily="Trebuchet MS" LayoutUpdated="courseslistview_LayoutUpdated"> <ListBox.ItemTemplate> <DataTemplate> <CheckBox Content="{Binding .}" /> </DataTemplate> </ListBox.ItemTemplate> </ListBox> How can I use C# to get all the checked checkboxes in the above ListBox? CodeNaked It would probably be best to bind the CheckBox to the IsSelected property of the ListBoxItem , like so: <DataTemplate> <CheckBox Content="{Binding .}" IsChecked="{Binding RelativeSource={RelativeSource AncestorType=

I have a ListBox with many objects displayed, each of which can be a variable height, based on the number of values each object has. See my previous question that was answered here. Many objects are 5-lines high, while others are 1. The scroll bar in the ListBox does not appear to like this, probably due to the virtualization. While you scroll through, the thumb on the scroll bar will change its size , based on how many items are actually fitting into the box at that current moment. This makes the thumb very big at times, and very small at other times. Since this ListBox is also contained

I have lots of images stored in isolated storage and want to display them in a listbox. However, I don't want all images to be loaded right away but lazily. So only when the user scrolls to see new items the images should be loaded. I also want to use data binding for providing the list item's data and image. In the tests I did all images always got loaded right away and at once, so I am unsure whether this lazy loading can be achieved with the default ListBox and data binding. Can it? You can use the standard ListBox to "lazy load" your items with databinding. The keyword here is "data

I want to convert the items to a String array or the type that I used to fill the ListBox.DataSource. The type has overridden ToString() but I can't seems to get it converted, not even to String[]. String[] a = (String[])ListBox1.Items; Contacts[] b = (Contacts[])ListBox1.Items; string[] a = ListBox1.Items.Cast<string>().ToArray(); Of course, if all you plan to do with a is iterate over it, you don't have to call ToArray(). You can directly use the IEnumerable<string> returned from Cast<string>() , e.g.: foreach (var s in ListBox1.Items.Cast<string>()) { do_something_with(s); } Or, if you have
