ASP.NET中常用的三十三種代碼第1/7頁

1. 開啟新的視窗並傳送參數：
傳送參數：
response.write("＜script＞window.open('*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"')＜/script＞")
接收參數：
string a = Request.QueryString("id");
string b = Request.QueryString("id1");
2.為按鈕添加對話方塊
Button1.Attributes.Add("onclick","return confirm('確認?')");
button.attributes.add("onclick","if(confirm('are you sure...?')){return true;}else{return false;}")
3.刪除表格選定記錄
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex];
string deleteCmd = "Delete from Employee where emp_id = " + intEmpID.ToString()
4.刪除表格記錄警告
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('您是否確定要刪除這條資訊');");
　break;
default:
　break;
　}
}
5.點擊表格行連結另一頁
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
　//點擊表格開啟
　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 + "');");
}
雙擊表格串連到另一頁
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 + "'");
}
雙擊表格開啟新一頁
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 + "')");
}
6.表格超串連列傳遞參數
＜asp:HyperLinkColumn Target="_blank" headertext="ID號" DataTextField="id" NavigateUrl="aaa.aspx?id='
　＜%# DataBinder.Eval(Container.DataItem, "資料欄位1")%＞' & name='＜%# DataBinder.Eval(Container.DataItem, "資料欄位2")%＞' /＞
7.表格點擊改變顏色
if (e.Item.ItemType == ListItemType.Item e.Item.ItemType == ListItemType.AlternatingItem)
{
　e.Item.Attributes.Add("onclick","this.style.backgroundColor='#99cc00';
　 this.style.color='buttontext';this.style.cursor='default';");
}
寫在DataGrid的_ItemDataBound裡
if (e.Item.ItemType == ListItemType.Item e.Item.ItemType == ListItemType.AlternatingItem)
{
e.Item.Attributes.Add("onmouseover","this.style.backgroundColor='#99cc00';
　this.style.color='buttontext';this.style.cursor='default';");
e.Item.Attributes.Add("onmouseout","this.style.backgroundColor='';this.style.color='';");
}
