1. 打開新的窗口並傳送參數︰
//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.為按鈕添加對話框
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信息’);");
break;
default:
break;
}
}
5.點擊表格行鏈接另一頁
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
//點擊表格打開
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 + "’);");
}
//雙擊表格連接到另一頁
//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 + "’");
}
//雙擊表格打開新一頁
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.表格超連接列傳遞參數
＜asp:HyperLinkColumn Target="_blank" headertext="ID號" DataTextField="id" NavigateUrl="aaa.aspx?id=’
＜%# DataBinder.Eval(Container.DataItem, "數據字段1")%＞’ & name=’＜%# DataBinder.Eval(Container.DataItem, "數據字段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里
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.關于日期格式
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.獲取錯誤信息並到指定頁面
//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");
//其余的非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信息，所以頁面導向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信息並進行相應的處理
