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 + "’)");} ★特別注意:【?id=】 處不能為 【?id =】
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=’’;");}
8.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"))
9.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.asaxprotected 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伺服器端執行,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
