在特定的细胞datagridview的C＃展示形象 [英] show image in specific cell datagridview c#

问题描述

         string fileName = "C:\\Users\\Shahid\\Pictures\\Picasa\\word.gif";
        FileInfo fileInfo = new FileInfo(fileName);

        byte[] binaryData = File.ReadAllBytes(fileName);  
        MemoryStream ms = new MemoryStream(binaryData);
        Image returnImage = Image.FromStream(ms, false, true);
        dataGridView1.Rows[i].Cells[2].Value = returnImage;
        dataGridView1.Rows[i].Cells[2].ToolTipText = fileInfo.ToString();

这展现在我的DataGridViewCell，而不是像System.Drawing.Bitmap。

this show "System.Drawing.Bitmap" in my DataGridViewCell instead of image.

推荐答案

要渲染，你必须使用图像的 DataGridViewImageColumn 列。您也可以使用 CellPainting 事件吸取/漆图像/每个或特定的细胞绘制。

To render an image you have to use DataGridViewImageColumn column. You can also use CellPainting event to draw/paint image/drawing on each or specific cell.

 private void dataGridView1_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)
 {
   if (e.RowIndex==1 && e.ColumnIndex==1)
   {
    using (Image img = Image.FromFile(@"c:\file\file.gif"))
     {
       e.Graphics.DrawImage(img, e.CellBounds.Left, e.CellBounds.Top - 1, e.CellBounds.Right, e.CellBounds.Bottom - 1);

       e.PaintContent(e.ClipBounds);
       e.Handled = true;
      }
    }
 }
