asp.net常见问题解决办法
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; } } |
