绑定时，添加事件：

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        // Get the LinkButton control in the first cell
        LinkButton _singleClickButton = (LinkButton)e.Row.Cells[0].Controls[0];
        // Get the javascript which is assigned to this LinkButton
        string _jsSingle = ClientScript.GetPostBackClientHyperlink(
            _singleClickButton, "");

        // Add events to each editable cell
        for (int columnIndex = _firstEditCellIndex; columnIndex < 
            e.Row.Cells.Count; columnIndex++)
        {
            // Add the column index as the event argument parameter
            string js = _jsSingle.Insert(_jsSingle.Length - 2, 
                columnIndex.ToString());
            // Add this javascript to the onclick Attribute of the cell
            e.Row.Cells[columnIndex].Attributes["onclick"] = js;
            // Add a cursor style to the cells
            e.Row.Cells[columnIndex].Attributes["style"] += 
                "cursor:pointer;cursor:hand;";
        }
    }
}
