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:

　　

public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
            this.Load += new EventHandler(Form_Load);
        }

        Timer timer = new Timer();
        RepositoryItemProgressBar progressbar = new RepositoryItemProgressBar();

        private void Form_Load(object sender, EventArgs e)
        {
            progressbar.LookAndFeel.UseDefaultLookAndFeel = false;
            progressbar.ShowTitle = true;
            //皮肤,这里使用的Dev自带的几款皮肤之一
            progressbar.LookAndFeel.SkinName = "Money Twins";
            //progressbar.LookAndFeel.Style = DevExpress.LookAndFeel.LookAndFeelStyle.Office2003;

            InitData();
            timer.Interval = 100;
            timer.Tick += new EventHandler(timer_Tick); 
            timer.Start();
        }

        private void timer_Tick(object sender, EventArgs e)
        {
            objects.ForEach(x =>{
                if (x.Index < x.Count) x.Index++;
                else x.Index = 0;
            });
            this.gridControl.RefreshDataSource();
        }

        private List<TestObject> objects = new List<TestObject>();

        public void InitData()
        {
            objects.Clear();
            objects.Add(new TestObject() { ID="A0001",Name="Francis",Count=100,Index=0});
            objects.Add(new TestObject() { ID = "A0002", Name = "Andy", Count = 1000, Index = 0 });
            objects.Add(new TestObject() { ID = "A0003", Name = "Tom", Count = 20, Index = 0 });
            objects.Add(new TestObject() { ID = "A0004", Name = "Achang", Count = 50, Index = 0 });
            this.gridControl.DataSource = objects;
            this.gridView.Columns["Count"].Visible = false;
            this.gridView.Columns["Index"].AppearanceCell.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;
        }

        private void gridView_CustomRowCellEdit(object sender, DevExpress.XtraGrid.Views.Grid.CustomRowCellEditEventArgs e)
        {
            if (e.Column.FieldName == "Index")
            {
                int count = (int)this.gridView.GetRowCellValue(e.RowHandle, "Count");
                int index = (int)e.CellValue;
                progressbar.Maximum = count;
                e.RepositoryItem = progressbar;
            }
        }

        private void gridView_CustomDrawCell(object sender, DevExpress.XtraGrid.Views.Base.RowCellCustomDrawEventArgs e)
        {
            if (e.Column.FieldName == "Index")
            {
                int count = (int)this.gridView.GetRowCellValue(e.RowHandle, "Count");
                int index = (int)e.CellValue;
                e.DisplayText = string.Format("{0}/{1}",index,count);
            }
        }
    }

    public class TestObject
    {
        public string ID { get; set; }
        public string Name { get; set; }
        public int Count { get; set; }
        public int Index { get; set; }
    }

　　显示效果如下:
