This article is about how to use listView. I think it is very practical, so I share it with you. I hope you can get something after reading this article. Let's take a look at it with the editor.
1. Basic use:
ListView.View = View.Details;// Settings View listView.SmallImageList = imageList;// Settings Icon / / add columns listView.Columns.Add ("Local path", 150, HorizontalAlignment.Left); listView.Columns.Add ("remote path", 150, HorizontalAlignment.Left); listView.Columns.Add ("upload status", 80, HorizontalAlignment.Left); listView.Columns.Add ("time consuming", 80, HorizontalAlignment.Left); / / add rows var item = new ListViewItem (); item.ImageIndex = 1 Item.Text = name; / / local path item.SubItems.Add (path); / / remote path item.SubItems.Add ("ok"); / / execution status item.SubItems.Add ("0.5"); / / time statistics listView.BeginUpdate (); listView.Items.Add (item); listView.Items [listView.Items.Count-1] .EnsureVisible (); / / scroll to the last listView.EndUpdate ()
Second, dynamically add records, ListView does not flicker:
1. Create a new C# class named ListViewNF (NF=Never/No Flickering)
two。 Copy the following code
Class ListViewNF: System.Windows.Forms.ListView {public ListViewNF () {/ / Activate double buffering this.SetStyle (ControlStyles.OptimizedDoubleBuffer | ControlStyles.AllPaintingInWmPaint, true); / / Enable the OnNotifyMessage event so we get a chance to filter out / / Windows messages before they get to the form's WndProc this.SetStyle (ControlStyles.EnableNotifyMessage, true) } protected override void OnNotifyMessage (Message m) {/ / Filter out the WM_ERASEBKGND message if (m.Msg! = 0x14) {base.OnNotifyMessage (m);}
3. Modify the xxxx.Design.cs corresponding to your WinForm and change the default System.Windows.Forms.ListView generated by the system to ListViewNF.
3. Add records dynamically and jump to the last line:
Implementation code:
ListViewItem Item = new ListViewItem (); Item.SubItems.Clear (); Related other codes this.listView1.Items.Add (Item); Item.EnsureVisible (); / / key implementation functions
4. Click the header to sort:
1. Add a custom sort class:
Using System;using System.Collections;using System.Windows.Forms;namespace Whir.Software.Framework.UI {public class ListViewSort: IComparer {private readonly int _ col; private readonly bool _ descK; public ListViewSort () {_ col = 0;} public ListViewSort (int column, object desc) {_ descK = (bool) desc; _ col = column / / at the top of the list, 0SubItems 1 col 2. Parameters are passed by the ColumnClick event of the ListView control} public int Compare (object x, object y) {int tempInt = String.CompareOrdinal (ListViewItem) x). SubItems [_ col] .text, ((ListViewItem) y). SubItems [_ col] .text) If (_ descK) {return-tempInt;} return tempInt;}
two。 Add click header events to ListView:
Private void listView_ColumnClick (object sender, ColumnClickEventArgs e) {if (listView.Columns [e.Column] .tag = = null) {listView.Columns.tag = true;} var tabK = (bool) listView.Columns [e.Column] .tag; listView.Columns [e.Column] .tag =! tabK; listView.ListViewItemSorter = new ListViewSort (e.Column, listView.Columns [e.Column] .tag) / / specify the sorter and send the column index and the ascending and descending keyword listView.Sort (); / / Custom sort a pair of lists} this is how to use listView.
