首先可以使用DevExpress GridControl 自带的进度条控件.
但是我要用一个方法来设置所以的单元格进度,而不是每个单元格都要设置一遍,同时我想要根据进度值不同,进度条显示不同的颜色.
那么就要自己手动的编写代码来完成了.
1 public void DrawProgressBar(DevExpress.XtraGrid.Views.Base.RowCellCustomDrawEventArgs e)
2 {
3 string s = e.CellValue as string;
4 s = s.Substring(0, e.CellValue.ToString().Length - 1);
5 decimal percent = Convert.ToDecimal(s);
6 int width = (int)(100 * Math.Abs(percent /100 ) * e.Bounds.Width / 100);
7 Rectangle rect = new Rectangle(e.Bounds.X, e.Bounds.Y, width, e.Bounds.Height);
8 Brush b = Brushes.Green;
9 if (percent < 50)
10 {
11 b = Brushes.Red;
12 }
13 e.Graphics.FillRectangle(b, rect);
14 }
1 private void gridView1_CustomDrawCell(object sender, DevExpress.XtraGrid.Views.Base.RowCellCustomDrawEventArgs e)
2 {
3 if (e.Column.FieldName == "CLASSPACE")
4 {
5 DrawProgressBar(e);
6
7 e.Handled = true;
8
9 DrawEditor(e);
10 }
11 }
代码:
1 private void DrawEditor(DevExpress.XtraGrid.Views.Base.RowCellCustomDrawEventArgs e)
2 {
3 GridCellInfo cell = e.Cell as GridCellInfo;
4 Point offset = cell.CellValueRect.Location;
5 BaseEditPainter pb = cell.ViewInfo.Painter as BaseEditPainter;
6 AppearanceObject style = cell.ViewInfo.PaintAppearance;
7 if (!offset.IsEmpty)
8 cell.ViewInfo.Offset(offset.X, offset.Y);
9 try
10 {
11 pb.Draw(new ControlGraphicsInfoArgs(cell.ViewInfo, e.Cache, cell.Bounds));
12 }
13 finally
14 {
15 if(!offset.IsEmpty)
16 {
17 cell.ViewInfo.Offset(-offset.X, -offset.Y);
18 }
19 }
20 }
同时 将 单元格设置为不可编辑状态.
附 最后显示效果 :
DevExpress GridControl 单元格添加进度条(ProgressBar)
