Now run the application,a new window appears like below screen:
Example
Data binding with Item template for List box:Create a new window, then go to XAML source and write the following code:
[csharp]
<Window x:Class="WPFListbox.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="WPF | ListBox" Height="300" Width="300" Background="Black">
<Grid Margin="10">
<ListBox Name="lstempinfo" HorizontalContentAlignment="Stretch" Width="200"
Margin="0,10,0,10" Background="LightPink" FontFamily="Tahoma" FontWeight="Bold">
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding EmpName}" />
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</Grid>
</Window>
[/csharp]
Then the window becomes like below:
Now go to code behind file and write the following code:
[csharp]using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Shapes;
namespace WPFListbox
{
/// <summary>
/// Interaction logic for ListBox1.xaml
/// </summary>
public partial class ListBox1 : Window
{
public ListBox1()
{
InitializeComponent();
lstempinfo.ItemsSource = lstemp;
GetEmp();
}
List&lt;EmployeeInfo&gt; lstemp = new List&lt;EmployeeInfo&gt;();
void GetEmp()
{
lstemp.Add(new EmployeeInfo() { Empid = 111, EmpName = "SPlessons" });
lstemp.Add(new EmployeeInfo() { Empid = 112, EmpName = "SPlessons" });
lstemp.Add(new EmployeeInfo() { Empid = 113, EmpName = "SPlessons" });
lstemp.Add(new EmployeeInfo() { Empid = 114, EmpName = "SPlessons" });
lstemp.Add(new EmployeeInfo() { Empid = 115, EmpName = "SPlessons" });
lstemp.Add(new EmployeeInfo() { Empid = 116, EmpName = "SPlessons" });
lstemp.Add(new EmployeeInfo() { Empid = 117, EmpName = "SPlessons" });
lstemp.Add(new EmployeeInfo() { Empid = 111, EmpName = "SPlessons" });
lstemp.Add(new EmployeeInfo() { Empid = 112, EmpName = "SPlessons" });
lstemp.Add(new EmployeeInfo() { Empid = 113, EmpName = "SPlessons" });
lstemp.Add(new EmployeeInfo() { Empid = 114, EmpName = "SPlessons" });
lstemp.Add(new EmployeeInfo() { Empid = 115, EmpName = "SPlessons" });
lstemp.Add(new EmployeeInfo() { Empid = 116, EmpName = "SPlessons" });
lstemp.Add(new EmployeeInfo() { Empid = 117, EmpName = "SPlessons" });
}
public class EmployeeInfo
{
public int Empid { get; set; }
public string EmpName { get; set; }
}
}
}[/csharp]
Now run the application, the result appears like below.
Example
Data Binding from Database to List box:Create a new window, then go to xaml source and write the following code:
[csharp]
<Window x:Class="WPFListbox.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="WPF | ListBox" Height="350" Width="325" Background="RosyBrown">
<Grid Margin="10">
<ListBox Name="emptrancations" HorizontalContentAlignment="Stretch" Width="200"
Margin="0,10,0,10" Background="Maroon" FontWeight="Bold">
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding EName}"/>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</Grid>
</Window>
[/csharp]
Then the window should become like below.
Now go to code behind file and write the following code:
[csharp]using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
using System.Data.SqlClient;
using System.Data;
namespace WPFListbox
{
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
GetEmployee();
}
void GetEmployee()
{
SqlConnection con = new
SqlConnection("Server=srinu;database=Test;uid=sa;pwd=Srinu20!5;");
SqlCommand cmd = new SqlCommand("select * from Employee", con);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataTable ds = new DataTable();
da.Fill(ds);
con.Open();
cmd.ExecuteReader();
con.Close();
emptrancations.ItemsSource = ds.DefaultView;
}
}
}
[/csharp]
Now run the application, then result appears like below.
