listbox

I have a listbox containing Users. The datasource is an generic list of the type User (contains, id, firstname, lastname, ...). Now I want to use the id as datavalue (through dataValueField) and I want LastName + ' ' + Firstname as a DataTextField. Can anyone tell me how this is possible? I'm using C# (ASP.NET). The easiest way is to add a new property to the User class that contains the full name: public string FullName { get { return LastName + " " + FirstName; } } And bind the listbox to that. This has the advantage of centralising the logic behind how the full name is constructed, so you

I would like to know what is the easiest way to print ListBox's values. I have tried to use FlowDocumentReader but with no success. If you are trying to print a visual element,you can use PrintDialog printDlg = new PrintDialog(); printDlg.PrintVisual(ListBox1, "Listbox Printing."); It can be used to print any visual object(any control, container, Window or user control) If you are looking to print the items only then you can use the FlowDocument FlowDocument fd = new FlowDocument(); foreach (object item in items) { fd.Blocks.Add(new Paragraph(new Run(item.ToString()))); } fd.Print(); or

XAML: <Window x:Class="WpfApp_ListBoxTest.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300"> <Grid> <ListBox Name="lb" Margin="0,0,0,70"></ListBox> <Button Height="23" HorizontalAlignment="Left" Margin="12,0,0,41" Name="btnAdd" VerticalAlignment="Bottom" Content="Add item" Width="75" Click="btnAdd_Click"></Button> <TextBox Height="23" Margin="93,0,12,41" Name="txtInput" VerticalAlignment="Bottom" /> <Button Height="23" HorizontalAlignment="Left" Margin="12,0,0,12" Name=

I am trying to read value from a listbox item that is on another thread. I tried to make a new method to run the invoke command, I can manage to send a command to the listbox like add via the invoke method but i cant seem to get a response, i cant seem to get the value of the item, i have tried a few ways, once i change it from a void to a string things start to get hairy... thread t1 = new thread(thethread) t1.start() public void thethread() { string text = readListBoxSelected(listBox1) + " lala" ; } public static string readListBoxSelected(ListBox listbox) { if (listbox.InvokeRequired) {

How would one go about styling a listbox such that the selection has a different text color than the default view? I've looked at this in several ways and because the ContentPresenter lacks a Foreground property. The default control template of the listbox provides several rectangles which one can use to adjust the highlight color. For example, with the default style a rectangle called BGColor3 has its opacity adjusted to get a highlight effect. Here is the bulk of my control template: <Grid> <Rectangle x:Name="BGColor2" Fill="{StaticResource HoverBrush}" Stroke="Black" StrokeThickness="1"

I've got a ListBox that is used to show items of multiple types (all derived from the same base type) that are bound to the ItemsSource through an ObservableCollection<T> . The performance of said ListBox is terrible. It appears that virtualization is disabled. According to: http://msdn.microsoft.com/en-us/library/cc716879(v=vs.110).aspx it seems that adding items of multiple types to the ItemsControl may be the problem. Here's my ListBox's style: <Style x:Key="{x:Type ListBox}" TargetType="{x:Type ListBox}"> <Setter Property="ScrollViewer.CanContentScroll" Value="true" /> <Setter Property=

Currently I have 2 listboxes binding data from a database on my view... I've used a custom Viewmodel and it is not strongly-typed. Here's the code: <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<ProjectenII.Models.Domain.StudentModel>"%> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> IndexStudents </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2>IndexStudents</h2> <div class="editor-field"> <%: Html.ListBox("IndexStudentsNormal", Model
