        {
            string picPath = @"....";
            System.IO.FileStream fs = new System.IO.FileStream(picPath, System.IO.FileMode.Open);
            Image im = Image.FromStream(fs);
            fs.Close();
            if (e.ColumnIndex == 0)
            {

Answer 2

路径这里有点不太明白啊，可以详细点不，加载的时候用dataset绑定，那这里的图片路径怎样获取好呢

Answer 3

        private void DataGridView_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
        {
            if (e.Control is DataGridViewComboBoxEditingControl && this.DataGridView.CurrentCell.ColumnIndex == 4 && this.DataGridView.CurrentCell.RowIndex != -1)
            {
                this.DataGridViewComboBox = (DataGridViewComboBoxEditingControl)e.Control;
                DataGridViewComboBox.SelectionChangeCommitted += new EventHandler(this.DataGridViewComboBox_SelectionChangeCommitted);
            }
        }        private void DataGridViewComboBox_SelectionChangeCommitted(object sender, EventArgs e)
        {
             ##你要做的事
                    }        private void DataGridView_CellEndEdit(object sender, DataGridViewCellEventArgs e)
        {
            if (this.DataGridViewComboBox != null)
            {
                DataGridViewComboBox.SelectionChangeCommitted -= new EventHandler(this.DataGridViewComboBox_SelectionChangeCommitted);
                this.DataGridViewComboBox = null;
            }
        }

Answer 4

private DataGridViewComboBoxEditingControl DataGridViewComboBox = null;5楼漏了一句

Answer 5

编辑datagridview时，不需要把 DataGridViewTextBoxColumn  换成DataGridViewComboBoxColumn吧

Answer 6

手动换一下，然后DataPropetyName绑定下源！反正我是这么搞定的

Answer 7

 private void DataGridViewComboBox_SelectionChangeCommitted(object sender, EventArgs e)
  {
  ##你要做的事
  }
这是个事件？？？？？？

Answer 8

这个是下拉框index改变了，驱动其他数据变化的事件啊 比如级联之类的

Answer 9

图片
private void dataGridview1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)   
{   
  if (dataGridview1.Columns[e.ColumnIndex].Name.Equals("Image"))   
  {   
  string path = e.Value.ToString();   
  e.Value = GetImage(path);   
  }   
}   
public System.Drawing.Image GetImage(string path)   
{   
  System.IO.FileStream fs = new System.IO.FileStream(path, System.IO.FileMode.Open);   
  System.Drawing.Image result = System.Drawing.Image.FromStream(fs);     fs.Close();     return result;   }   
使用DataGridViewImageColumn   
DataGridViewImageColumn column = new DataGridViewImageColumn();   
dataGridView1.Columns.Add(column);   
column.HeaderText = "图片";   
column.Image = System.Drawing.Image.FromFile("路径"); private void dataGridView1_EditingControlShowing(object sender,
  DataGridViewEditingControlShowingEventArgs e)
{
  ComboBox combo = e.Control as ComboBox;
  if (combo != null)
  {
  combo.SelectedIndexChanged +=
  new EventHandler(ComboBox_SelectedIndexChanged);
  }
}
private void ComboBox_SelectedIndexChanged(object sender, EventArgs e)
{
 ComboBox cb=(ComboBox)sender;
}
