在网格视图中重新加载数据. [英] Reload Data's in grid view.

问题描述

大家好，
我在网格中添加了一些项目.

Hi all,
I am adding some items in the grid.

by using  this way,
 1. Created a datatable
 2. Added Row in the Table
 3. Binded the datatable as Gird's Source

例如，网格有4行.

不幸的是，系统电源故障.我想在重新打开应用程序时重新加载那4行.

如果最终用户故意用网格中的行终止应用程序，则当他重新打开网格时应重新加载相同的数据.



该怎么做?

问候，
Pal

For example grid has 4 rows.

unfortunately system power fails. I want to reload that 4 rows when the application is reopened.

if end user purposely terminates the application with rows in grid, when he reopens grid should reload the same data.



how to do this?

regards,
Pal
