ASP.NET 网格视图到记录的删除、排序和分页

Question

我是 ASP.NET 新手。

我正在使用 DataGrid 设计一个 ASP.NET 页面，我将在其中执行以下任务。请建议什么是最好的方法。

1） 在

网格上显示数据库中的记录，如下所示（启用分页）

Cloum1|Colum2|Column3|<CheckBox>
--------------------------------
Colva1|Colva4|Colvaa3|<CheckBox>
Colva1|Colva4|Colvaa3|<CheckBox>
Colva1|Colva4|Colvaa3|<CheckBox>
Colva1|Colva4|Colvaa3|<CheckBox>
Colva1|Colva4|Colvaa3|<CheckBox>
Colva1|Colva4|Colvaa3|<CheckBox>
Colva1|Colva4|Colvaa3|<CheckBox>
Colva1|Colva4|Colvaa3|<CheckBox>
            [DELETE Button]
{Solution proposed: Upon load event of the page bind grid with List of entities retrieved from the DB on grid using DataBind(), enable sorting, and paging (currently doing paging and sorting on post back events :()}
{Required help: best approach in doing paging and sorting on the gird with considering performance??}

2)Deleting records :
    -User should be able to navigate to multiple pages on the grid, and should be able to check records which he want to delete form
    {Solution proposed: Upon load event of the page bind grid with List of entities retrieved from the DB on grid using DataBind()}
    -After clicking on Delete button all the records from the DB should be removed.
    {Solution proposed- on Delete button submit click run delete operation using ADO.NET via SP on all the selected records.}
    {Required help: Best approach in this case, how to track the number of records selected for Delete on multiple pages}
    -Incase user sorts the records on the page they shouldn't do a post back instead maintain the state of whether records are checked for delete.
    {Required help: unsure on how to handle this??}

谢谢。
