ASP.Net開發實用小技巧備忘錄
阿新 • • 發佈:2019-02-03
傳送引數:
response.write("<script>window.open
('*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"')</script>")
接收引數:
string a = Request.QueryString("id");
string b = Request.QueryString("id1");
2.為按鈕新增對話方塊
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.點選表格行連結另一頁
private void grdCustomer_ItemDataBound
(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
//點選表格開啟
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 + "');");
}
雙擊表格連線到另一頁,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.表格超連線列傳遞引數
<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.表格點選改變顏色
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}"
