Devexpress-进度条
Devexpress控件中,进度条控件为ProgressBarControl, 在数据型控件中进度条为RepositoryItemProgressBar.
常用的设置
- 样式或者皮肤
- 进度设置
- 进度文字显示
样式或者皮肤
进度控件的默认颜色是无法直接更改的,因为显示的优先是样式和皮肤，只有设置不使用默认主题就可以进行改变了.
progressbar.LookAndFeel.UseDefaultLookAndFeel = false;
进度设置
进度的三要素:最大值 当前值 递增量
progressbar.Maximum = 200; //总进度 progressbar.Step=1; //进度的递增量 progressbar.Text="55"; //当前进度
进度文字显示
进度条在展示进度的同时,还可以显示百分比(可格式化精度)或详细进度,亦可自定义显示
progressbar.ShowTitle = true; //允许显示文字 progressbar.PercentView=true;//true显示百分比(默认),false显示详细进度
如下显示:
关于在数据绑定型控件中
有的时候每行的进度的最大值都是不同的,而在进度到达某一范围需要显示不同的样式.这里我们就需要手动去设置数据对应我们预先定义好的RepositoryItemProgressBar
下面是一个简单例子:
1 public partial class Form1 : Form
2 {
3 public Form1()
4 {
5 InitializeComponent();
6 this.Load += new EventHandler(Form_Load);
7 }
8
9 Timer timer = new Timer();
10 RepositoryItemProgressBar progressbar = new RepositoryItemProgressBar();
11
12 private void Form_Load(object sender, EventArgs e)
13 {
14 progressbar.LookAndFeel.UseDefaultLookAndFeel = false;
15 progressbar.ShowTitle = true;
16 //皮肤,这里使用的Dev自带的几款皮肤之一
17 progressbar.LookAndFeel.SkinName = "Money Twins";
18 //progressbar.LookAndFeel.Style = DevExpress.LookAndFeel.LookAndFeelStyle.Office2003;
19
20 InitData();
21 timer.Interval = 100;
22 timer.Tick += new EventHandler(timer_Tick);
23 timer.Start();
24 }
25
26 private void timer_Tick(object sender, EventArgs e)
27 {
28 objects.ForEach(x =>{
29 if (x.Index < x.Count) x.Index++;
30 else x.Index = 0;
31 });
32 this.gridControl.RefreshDataSource();
33 }
34
35 private List<TestObject> objects = new List<TestObject>();
36
37 public void InitData()
38 {
39 objects.Clear();
40 objects.Add(new TestObject() { ID="A0001",Name="Francis",Count=100,Index=0});
41 objects.Add(new TestObject() { ID = "A0002", Name = "Andy", Count = 1000, Index = 0 });
42 objects.Add(new TestObject() { ID = "A0003", Name = "Tom", Count = 20, Index = 0 });
43 objects.Add(new TestObject() { ID = "A0004", Name = "Achang", Count = 50, Index = 0 });
44 this.gridControl.DataSource = objects;
45 this.gridView.Columns["Count"].Visible = false;
46 this.gridView.Columns["Index"].AppearanceCell.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;
47 }
48
49 private void gridView_CustomRowCellEdit(object sender, DevExpress.XtraGrid.Views.Grid.CustomRowCellEditEventArgs e)
50 {
51 if (e.Column.FieldName == "Index")
52 {
53 int count = (int)this.gridView.GetRowCellValue(e.RowHandle, "Count");
54 int index = (int)e.CellValue;
55 progressbar.Maximum = count;
56 e.RepositoryItem = progressbar;
57 }
58 }
59
60 private void gridView_CustomDrawCell(object sender, DevExpress.XtraGrid.Views.Base.RowCellCustomDrawEventArgs e)
61 {
62 if (e.Column.FieldName == "Index")
63 {
64 int count = (int)this.gridView.GetRowCellValue(e.RowHandle, "Count");
65 int index = (int)e.CellValue;
66 e.DisplayText = string.Format("{0}/{1}",index,count);
67 }
68 }
69 }
70
71 public class TestObject
72 {
73 public string ID { get; set; }
74 public string Name { get; set; }
75 public int Count { get; set; }
76 public int Index { get; set; }
77 }
显示效果如下:
