asp.net開發常用技巧收集

asp.net|技巧

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 =】
