导读:ASP.NET中常用的三十三种代码
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 + "')"); } 6.表格超连接列传递参数 <asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=' <%# DataBinder.Eval(Container.DataItem, "数据字段1")%>' & name='<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>' /> 7.表格点击改变颜色 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';"); } 写在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='';"); } 1 (编辑:焦作站长网) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
