C#之常用控件集合（英文版）

The ListView control is an ItemsControl that is derived from ListBox.

Add Columns in ListView

You can add columns in Listview by using Columns.Add() method. This method takes two arguments, first one is the Column heading and second one the column width.

listView1.Columns.Add("ProductName", 100);

In the above code, "ProductName" is column heading and 100 is column width.

Add Item in Listview

You can add items in listbox using ListViewItem which represents an item in a ListView control.

string[] arr = new string[4];
ListViewItem itm;//add items to ListView
arr[0] = "product_1";
arr[1] = "100";
arr[2] = "10";
itm = new ListViewItem(arr);
listView1.Items.Add(itm);

Get selected item from ListView

productName = listView1.SelectedItems[0].SubItems[0].Text;

Above code will return the itme from first column of first row.

Sorting Listview Items

If the Sorted property of Listview is set to true, then the ListView items are sorted. The following code sorts the ListView items:

ListView1.Sorted = true;

Add Checkbox in Listview

You can add checkbox in Listview columns.

myListView.CheckBoxes = true;myListView.Columns.Add(text, width, alignment);

ListView provides a large number of properties that provide flexibility in appearance and behavior. The View property allows you to change the way in which items are displayed. The SelectionMode property for a ListView determines how many items a user can select at one time.

The following C# program first set its view property as Details and GridLines property as true and FullRowSelect as true.

listView1.View = View.Details;listView1.GridLines = true;listView1.FullRowSelect = true;

Finally at the button click event, it will display the selected row values in a message box.

using System;
using System.Drawing;
using System.Windows.Forms;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
listView1.View = View.Details;
listView1.GridLines = true;
listView1.FullRowSelect = true;
//Add column header
listView1.Columns.Add("ProductName", 100);
listView1.Columns.Add("Price", 70);
listView1.Columns.Add("Quantity", 70);
//Add items in the listview
string[] arr = new string[4];
ListViewItem itm ;
//Add first item
arr[0] = "product_1";
arr[1] = "100";
arr[2] = "10";
itm = new ListViewItem(arr);
listView1.Items.Add(itm);
//Add second item
arr[0] = "product_2";
arr[1] = "200";
arr[2] = "20";
itm = new ListViewItem(arr);
listView1.Items.Add(itm);
}
private void button1_Click(object sender, EventArgs e)
{
string productName = null;
string price = null;
string quantity = null;
productName = listView1.SelectedItems[0].SubItems[0].Text;
price = listView1.SelectedItems[0].SubItems[1].Text;
quantity = listView1.SelectedItems[0].SubItems[2].Text;
MessageBox.Show (productName + " , " + price + " , " + quantity);
}
}
}
