1. 打开新的窗口并传送参数：

　　传送参数：

response.write("＜script＞window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)＜/script＞")
　　接收参数：

string a = Request.QueryString("id");
string b = Request.QueryString("id1");
　　2.为按钮添加对话框

Button1.Attributes.Add("onclick","return confirm(’确认?’)");
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}")
　　3.删除表格选定记录

int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex];
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString()
　　4.删除表格记录警告

private void DataGrid_ItemCreated(Object sender,DataGridItemEventArgs e)
{
　switch(e.Item.ItemType)
　{
　　case ListItemType.Item :
　　case ListItemType.AlternatingItem :
　　case ListItemType.EditItem:
　　　TableCell myTableCell;
　　　myTableCell = e.Item.Cells[14];
　　　LinkButton myDeleteButton ;
　　　myDeleteButton = (LinkButton)myTableCell.Controls[0];
　　　myDeleteButton.Attributes.Add("onclick","return confirm(’您是否确定要删除这条信息’);");
　　　break;
　　default:
　　　break;
　}

}
　　5.点击表格行链接另一页

private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
　//点击表格打开
　if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
　　e.Item.Attributes.Add("onclick","window.open(’Default.aspx?id=" + e.Item.Cells[0].Text + "’);");
}
　　双击表格连接到另一页

　　在itemDataBind事件中

if(e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
　string OrderItemID =e.item.cells[1].Text;
　...
　e.item.Attributes.Add("ondblclick", "location.href=’../ShippedGrid.aspx?id=" + OrderItemID + "’");
}
　　双击表格打开新一页

if(e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
　string OrderItemID =e.item.cells[1].Text;
　...
　e.item.Attributes.Add("ondblclick", "open(’../ShippedGrid.aspx?id=" + OrderItemID + "’)");
}
　　★特别注意：【?id=】处不能为【?id =】
