이 글에서는 참고할만한 좋은 C#을 이용하여 스텝 제어를 구현하는 단계를 주로 소개합니다. 아래 편집기를 사용하여 살펴보겠습니다.
지금은 많은 javascript 컨트롤이 있는데 매우 훌륭합니다. 그 중 하나는 아래 그림과 같이 단계입니다.
그럼 C#을 사용하여 단계 제어를 구현하는 방법은 무엇입니까?
먼저 StepEntity 클래스를 정의하여 스텝 바 노드 정보 :
public class StepEntity { public string Id { get; set; } public string StepName { get; set; } public int StepOrder { get; set; } public eumStepState StepState { get; set; } public string StepDesc { get; set; } public object StepTag { get; set; } //public Image StepCompletedImage { get; set; } //public Image StepDoingImage { get; set; } public StepEntity(string id,string stepname,int steporder,string stepdesc, eumStepState stepstate,object tag) { this.Id = id; this.StepName = stepname; this.StepOrder = steporder; this.StepDesc = stepdesc; this.StepTag = tag; this.StepState = stepstate; } }
StepViewer라는 사용자 컨트롤을 정의합니다.
public partial class StepViewer : UserControl { public StepViewer() { InitializeComponent(); this.Height = 68; } }
다음과 같이 StepViewer 사용자 컨트롤에서 ListDataSource 속성을 정의합니다.
private List<StepEntity> _dataSourceList = null; [Browsable(true), Category("StepViewer")] public List<StepEntity> ListDataSource { get { return _dataSourceList; } set { if (_dataSourceList != value) { _dataSourceList = value; Invalidate(); } } }
이 컨트롤의 페인트 메서드에서 다음 단계를 수행합니다. 막대 그리기:
private void StepViewer_Paint(object sender, PaintEventArgs e) { if(this.ListDataSource!=null) { int CenterY = this.Height / 2; int index = 1; int count = ListDataSource.Count; int lineWidth = 120; int StepNodeWH = 28; //this.Width = 32 * count + lineWidth * (count - 1) + 6+300; //defalut pen & brush e.Graphics.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.HighQuality; Brush brush = new SolidBrush(_Gray); Pen p = new Pen(brush, 1f); Brush brushNode = new SolidBrush(_DarkGray); Pen penNode = new Pen(brushNode, 1f); Brush brushNodeCompleted = new SolidBrush(_Blue); Pen penNodeCompleted = new Pen(brushNodeCompleted, 1f); int initX = 6; //string Font nFont = new Font("微软雅黑", 12); Font stepFont = new Font("微软雅黑", 11,FontStyle.Bold); int NodeNameWidth = 0; foreach (var item in ListDataSource) { //round Rectangle rec = new Rectangle(initX, CenterY - StepNodeWH / 2, StepNodeWH, StepNodeWH); if (CurrentStep == item.StepOrder) { if (item.StepState == eumStepState.OutTime) { e.Graphics.DrawEllipse(new Pen(_Red,1f), rec); e.Graphics.FillEllipse(new SolidBrush(_Red), rec); } else { e.Graphics.DrawEllipse(penNodeCompleted, rec); e.Graphics.FillEllipse(brushNodeCompleted, rec); } //白色字体 SizeF fTitle = e.Graphics.MeasureString(index.ToString(), stepFont); Point pTitle = new Point(initX + StepNodeWH / 2 - (int)Math.Round(fTitle.Width) / 2, CenterY - (int)Math.Round(fTitle.Height / 2)); e.Graphics.DrawString(index.ToString(), stepFont, Brushes.White, pTitle); //nodeName SizeF sNode = e.Graphics.MeasureString(item.StepName, nFont); Point pNode = new Point(initX + StepNodeWH, CenterY - (int)Math.Round(sNode.Height / 2) + 2); e.Graphics.DrawString(item.StepName,new Font( nFont,FontStyle.Bold), brushNode, pNode); NodeNameWidth = (int)Math.Round(sNode.Width); if (index < count) { e.Graphics.DrawLine(p, initX + StepNodeWH + NodeNameWidth, CenterY, initX + StepNodeWH + NodeNameWidth + lineWidth, CenterY); } } else if (item.StepOrder < CurrentStep) { //completed e.Graphics.DrawEllipse(penNodeCompleted, rec); //image RectangleF recRF = new RectangleF(rec.X + 6, rec.Y + 6, rec.Width - 12, rec.Height - 12); e.Graphics.DrawImage(ControlsResource.check_lightblue, recRF); //nodeName SizeF sNode = e.Graphics.MeasureString(item.StepName, nFont); Point pNode = new Point(initX + StepNodeWH, CenterY - (int)Math.Round(sNode.Height / 2) + 2); e.Graphics.DrawString(item.StepName, nFont, brushNode, pNode); NodeNameWidth = (int)Math.Round(sNode.Width); if (index < count) { e.Graphics.DrawLine(penNodeCompleted, initX + StepNodeWH + NodeNameWidth, CenterY, initX + StepNodeWH + NodeNameWidth + lineWidth, CenterY); } } else { e.Graphics.DrawEllipse(p, rec); // SizeF fTitle = e.Graphics.MeasureString(index.ToString(), stepFont); Point pTitle = new Point(initX + StepNodeWH / 2 - (int)Math.Round(fTitle.Width) / 2, CenterY - (int)Math.Round(fTitle.Height / 2)); e.Graphics.DrawString(index.ToString(), stepFont, brush, pTitle); //nodeName SizeF sNode = e.Graphics.MeasureString(item.StepName, nFont); Point pNode = new Point(initX + StepNodeWH, CenterY - (int)Math.Round(sNode.Height / 2) + 2); e.Graphics.DrawString(item.StepName, nFont, brushNode, pNode); NodeNameWidth = (int)Math.Round(sNode.Width); if (index < count) { //line e.Graphics.DrawLine(p, initX + StepNodeWH + NodeNameWidth, CenterY, initX + StepNodeWH + NodeNameWidth + lineWidth, CenterY); } } //描述信息 if (item.StepDesc != "") { Point pNode = new Point(initX + StepNodeWH, CenterY+10); e.Graphics.DrawString(item.StepDesc,new Font(nFont.FontFamily,10),brush, pNode); } index++; //8 is space width initX = initX + lineWidth + StepNodeWH+ NodeNameWidth+8; } } }
컨트롤 사용:
List<StepEntity> list = new List<StepEntity>(); list.Add(new StepEntity("1", "新开单", 1, "这里是该步骤的描述信息", eumStepState.Completed, null)); list.Add(new StepEntity("2", "主管审批", 2, "这里是该步骤的描述信息", eumStepState.Waiting, null)); list.Add(new StepEntity("3", "总经理审批", 3, "这里是该步骤的描述信息", eumStepState.OutTime, null)); list.Add(new StepEntity("2", "完成", 4, "这里是该步骤的描述信息", eumStepState.Waiting, null)); this.stepViewer1.CurrentStep = 3; this.stepViewer1.ListDataSource = list;
마찬가지로 다음을 달성할 수 있습니다. 타임라인 제어.
