DevExpress BarEditItem 进度条默认是粉色的，如何单独修改进度条颜色而不通过皮肤控件？因为皮肤控件会对所有的DevExpress控件的主题产生影响
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:
复制代码
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();

显示效果如下:
