listbox

问题 The code below creates two list boxes. When an item in the first list box is selected, I am trying to select the corresponding item in the second list box when there is a match between NameOne and NameTwo. However, it does not select my item in the second list box. Why is that? XAML: <Window x:Class="ListBoxTesting.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525">

问题 In a ASP.NET MVC (Razor) project, I'm using a ListBox with Multi Select option in a Edit View, CONTROLLER public ActionResult Edit(int id) { Post post = db.Posts.Find(id); string selectedValues = post.Tags; //This contains Selected values list (Eg: "AA,BB") ViewBag.Tagslist = GetTags(selectedValues.Split(',')); return View(post); } private MultiSelectList GetTags(string[] selectedValues) { var tagsQuery = from d in db.Tags orderby d.Name select d; return new MultiSelectList(tagsQuery, "Name",

问题 So far I have the ability to delete one or multiple listbox items from a listbox but i want to be able to delete those exact items from the actual list as well. If you run the code the code that I provided you will see that it is the opposite ended list item that is getting deleted. For example, if i highlight "14" and remove it, the item removed from the list is "0" since we have a range of (0,15). Please take a look, any feedback is appreciated. import tkinter as tk class Example(tk.Tk):

问题 I used the listbox UI element in Wordpress 3.8, but it does not work in its newer version (3.9).

问题 Okay, I was able to create a simple Windows Forms project that reproduces some strange behavior I found. In the designer, make a form with a ListBox (named lbx) anchored Top, Left, Right, and Bottom, and a button (button1). Now, the Form's code is here: using System; using System.Windows.Forms; namespace ListBoxKaboom { public partial class Form1 : Form { private bool _initFinished = false; public Form1() { InitializeComponent(); this._initFinished = true; this.Height += 100; this.Height -=

问题 I am trying to add pinch to zoom feature to a data bound ListBox. What is the most efficient way to do this? I have placed the ListBox inside a Grid control and made it scrollable. This is my current code. <Grid x:Name="ContentPanel" Grid.Row="1" Margin="10,0,10,10" Background="Black" > <ListBox Name="lstText" FontSize="24" Foreground="White" SelectionMode="Single" Margin="10,0,10,10" ScrollViewer.VerticalScrollBarVisibility="Visible" > <ListBox.ItemTemplate> <DataTemplate> <StackPanel >
