ASP.NET常用的三十三种实用代码
1. 打开新的窗口并传送参数：
传送参数：
| response.write("＜script＞window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)＜/script＞") |
接收参数：
| string a = Request.QueryString("id"); string b = Request.QueryString("id1"); |
2.为按钮添加对话框
| Button1.Attributes.Add("onclick","return confirm(’确认?’)"); button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") |
3.删除表格选定记录
| int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() |
4.删除表格记录警告
| 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(’您是否确定要删除这条信息’);"); break; default: break; } } |
5.点击表格行链接另一页
| private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) { //点击表格打开 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 + "’);"); } |
双击表格连接到另一页
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 + "’"); } |
双击表格打开新一页
| 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 + "’)"); } |
★特别注意：【?id=】 处不能为 【?id =】
6.表格超连接列传递参数
| ＜asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ |
7.表格点击改变颜色
