DataGrid行的双击时弹出对话框和单击时行变色

首先在html代码中加入script代码

<script>
         function SelectDataGridRow(DataGridName,rowIndex) 
         { 
                var mytable=document.getElementById(DataGridName);
                 mytable.rows[rowIndex].oldcolor=mytable.rows[rowIndex].style.backgroundColor;
                 mytable.rows[rowIndex].style.backgroundColor='#C8F7FF';
                 for(var i=0;i<mytable.rows.length;i++)
                 {
                    if(i!=rowIndex)
                    {
                      mytable.rows[i].style.backgroundColor=mytable.rows[i].oldcolor;
                    }
                 }
         } 
        </script>

然后在cs文件中给DataGrid的ItemDataBound事件加入代码

        private void DataGrid1_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
        {
            if(e.Item.ItemType == ListItemType.AlternatingItem 
                || e.Item.ItemType == ListItemType.Item)
            {
                e.Item.Attributes.Add("onclick",
                    "SelectDataGridRow('DataGrid1',this.rowIndex);");
                
                e.Item.Attributes.Add("ondblclick",
                    "alert('您选择了第:'+this.rowIndex+'行,第3列的文字内容为:'+this.cells[2].innerText);");
                
            }
        }
