Farpoint如何在列头上添加自定义图片

farpoint支持在SheetView的列头上添加自定义的图片吗?如果支持的话,如何实现?

回复 1楼menghuanyunxia的帖子

Winform版本吗?

参考如下代码：

1. 
   
2. FarPoint.Win.Spread.CellType.ImageCellType icelltype = new FarPoint.Win.Spread.CellType.ImageCellType();
   
3.       icelltype.Style = FarPoint.Win.RenderStyle.Stretch;
   
4.       icelltype.TransparencyColor = Color.Black;
   
5.       icelltype.TransparencyTolerance = 100;
   
6.       fpSpread1.Sheets[0].Rows[0].CellType = icelltype;
   
7.       System.Drawing.Image image = System.Drawing.Image.FromFile(@"D:\_64.png");
   
8.       System.IO.MemoryStream stream = new System.IO.MemoryStream();
   
9.       byte[] bytes;
   
10.       string str;
    
11.       image.Save(stream, System.Drawing.Imaging.ImageFormat.Jpeg);
    
12.       stream.Seek(0, System.IO.SeekOrigin.Begin);
    
13.       bytes = stream.GetBuffer();
    
14.       str = System.Convert.ToBase64String(bytes);
    
15.       fpSpread1.Sheets[0].Cells[0, 0].Value = image;
    
16.       fpSpread1.Sheets[0].Cells[0, 1].Value = bytes;
    
17.       fpSpread1.Sheets[0].Cells[0, 2].Value = str;
    
18. 
    
19.       fpSpread1.Sheets[0].ColumnHeader.Rows[0].Height = 300;
    
20.       fpSpread1.Sheets[0].ColumnHeader.Cells[0, 0].CellType = icelltype;
    
21.       fpSpread1.Sheets[0].ColumnHeader.Cells[0, 0].Value = image;
