You can create picture type cell and put in it pictures. which you can show in Picture box when cell was clicked or entered. Or you can have only URL link in datagrid cells and when you click cell then URL link will be used to get image from.

您可以创建图片类型单元格并将其放入图片中。单击或输入单元格时，您可以在图片框中显示。或者您可以在datagrid单元格中只有URL链接，当您单击单元格时，将使用URL链接从中获取图像。

    private void bt_AddPicture_Click(object sender, EventArgs e)
    {
        //Add image to datagrid view
        //You can add picture from SQL database instead.
        dataGridView1.Rows.Add(Image.FromFile(@"c:\Users\Programmer\Desktop\tmp\tmp\Capture.PNG"));
    }

    private void bt_ShowPicture_Click(object sender, EventArgs e)
    {
        //Show image from datagrid view in picture box.
        //You can use it in event on cellEnter
        pictureBox1.Image = ( dataGridView1.Rows[0].Cells[0].Value as Image);
        pictureBox1.SizeMode = PictureBoxSizeMode.StretchImage;
    }

I came right

我说得对

    private void dgData_CellContentClick(object sender, DataGridViewCellEventArgs e)
    {
        picData.ImageLocation = dgData.CurrentRow.Cells[1].Value.ToString();
        picData.SizeMode = PictureBoxSizeMode.StretchImage;
    }

This worked very well
