GridView还有很多未知的有待于探索，Mark！
[解决办法]
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { for (int i = 0; i <= GridView1.Rows.Count; i++) { e.Row.Attributes.Add("onclick", "yourfunction(" +i+ ");"); e.Row.Attributes.Add("id",""+i+""); e.Row.Attributes.Add("ondblclick", "yourfunction2(" + i + ");"); } } }
