listbox

问题 What is the difference between "ListView" and "ListBox" in a "Windows 8" app. 回答1: The ListBox is an older control primarily for compatibility with other xaml frameworks. The ListView has build-in functionality for touch etc. Use the ListView unless you have a specific need for the ListBox See here for more detail. Specific events available only for ListView : DragItemsStarting ItemClick Methods: CompleteViewChange CompeteViewChangeFrom CompleteViewChangeTo InitializeViewChange

问题 I have the following code in my view: <%= Html.ListBoxFor(c => c.Project.Categories, new MultiSelectList(Model.Categories, "Id", "Name", new List<int> { 1, 2 }))%> <%= Html.ListBox("MultiSelectList", new MultiSelectList(Model.Categories, "Id", "Name", new List<int> { 1, 2 }))%> The only difference is that the first helper is strongly typed (ListBoxFor), and it fails to show the selected items (1,2), even though the items appear in the list, etc. The simpler ListBox is working as expected. I'm

问题 Is is possible to change the item selection focus color and text color in a TListBox? When themes are not enabled in the project, or the list box style is set to owner-draw, the selection around the item is painted blue, which I believe is globally defined by the system's appearance settings. I would like to change the color of selected items to a custom color. So an example, the result would be something like this: Note the last listbox has been modified in Paint to illustrate the example.

问题 I have a ListBox DataTemplate in WPF. I want one item to be tight against the left side of the ListBox and another item to be tight against the right side, but I can't figure out how to do this. So far I have a Grid with three columns, the left and right ones have content and the center is a placeholder with it's width set to "*". Where am I going wrong? Here is the code: <DataTemplate x:Key="SmallCustomerListItem"> <Grid HorizontalAlignment="Stretch"> <Grid.RowDefinitions> <RowDefinition/> <

问题 We want to set the SelectedItem of a ListBox programmatically and want that item to then have focus so the arrow keys work relative to that selected item. Seems simple enough. The problem however is if the ListBox already has keyboard focus when setting SelectedItem programmatically, while it does properly update the IsSelected property on the ListBoxItem , it doesn't set keyboard focus to it, and thus, the arrow keys move relative to the previously-focused item in the list and not the newly
