1.//彈出對話方塊.點擊轉向指定頁面
Response.Write(<script>window.alert('該會員沒有提交申請,請重新提交!') </script>);
Response.Write(<script>window.location='http://www.51aspx.com/bizpulic/upmeb.aspx' </script>);
2.//彈出對話方塊
Response.Write(<script language='javascript'>alert('產品添加成功!') </script >);
3.//刪除檔案
string filename =20059595157517.jpg;
pub.util.DeleteFile(HttpContext.Current.Server.MapPath(../file/) +filename);
4.//綁定下拉式清單方塊datalist
System.Data.DataView dv=conn.Exec_ex(select -1 as code,'請選擇經營模式'
as content from dealin union select code,content from dealin;);
this.dealincode.DataSource=dv;
this.dealincode.DataTextField=content;
this.dealincode.DataValueField=code;
this.dealincode.DataBind();
this.dealincode.Items.FindByValue(dv[0][dealincode].ToString()).Selected=true;
5.//時間去秒顯示
<%# System.DateTime.Parse(DataBinder.Eval (Container.DataItem,begtime).ToString()).ToShortDateString()%>
6.//標題帶連結
<%# <a class=\12c\ target=\_blank\href=\http://www.51aspx/CV/_DataBinder.Eval
(Container.DataItem,procode)+.html \>
DataBinder.Eval(Container.DataItem,proname") </a>%>
7.//修改轉向
<%# <A href=\"editpushpro.aspx?id=+DataBinder.Eval
(Container.DataItem,code)>修改
</A>%>
8.//彈出確定按鈕
<%# " <A id=\btnDelete\ onclick=\return confirm('你是否
確定刪除這條記錄嗎?');\ href=\pushproduct.aspx?
dl=DataBinder.Eval(Container.DataItem,code)
>刪除</A>%>
9.//輸出資料格式化 "{0:F2}" 是格式 F2表示小數點後剩兩位
<%# DataBinder.Eval(Container, DataItem.PriceMoney,{0:F2} ) %>
10.//提取動態網頁內容
Uri uri = new Uri(http://www.51aspx.com/);
WebRequest req = WebRequest.Create(uri);
WebResponse resp = req.GetResponse();
Stream str = resp.GetResponseStream();
StreamReader sr = new StreamReader(str,System.Text.Encoding.Default);
string t = sr.ReadToEnd();
this.Response.Write(t.ToString());
11.//擷取" . "後面的字元
i.ToString().Trim().Substring(i.ToString().Trim().LastIndexOf(.) +1).ToLower().Trim()
12. 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);
12.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;})
13.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() +“
14.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;
}
}
15.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 + ’));
}
16.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)%>’ / >
17.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=’’;);
}
18.關於日期格式
日期格式設定
DataFormatString="{0:yyyy-MM-dd}"
我覺得應該在itembound事件中
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd"))
19.擷取錯誤資訊併到指定頁面
不要使用Response.Redirect,而應該使用Server.Transfer
e.g
// in global.asax
protected void Application_Error(Object sender, EventArgs e)
{
if (Server.GetLastError() is HttpUnhandledException)
Server.Transfer(MyErrorPage.aspx);
//其餘的非HttpUnhandledException異常交給ASP.NET自己處理就okay了
}
Redirect會導致post-back的產生從而丟失了錯誤資訊,所以頁面導嚮應該直接在服
務器端執行,這樣就可以在錯誤處理頁面得到出錯資訊並進行相應的處理
