后台更新DataTable行内容的方法-.NET教程,数据库应用

这几天一直在找绑定后后台修改datatable行这方面的代码，发现很少，但是又不得不实现这样的功能，通过查帮助，自己解决了：）

我是将datatable绑定到listbox上，通过修改datatable来修改listbox值

listbox1.beginupdate(); // stop the listbox from drawing while items are added.

datatable dt;

int indexnum=listbox1.selectedindex;

dt=(datatable)listbox1.datasource;

datarow custrow = dt.rows[indexnum];

custrow.beginedit();

custrow[0] = indexnum;

custrow[1]="after modify";

custrow.endedit();

dt.acceptchanges();

listbox1.endupdate();// end the update process and force a repaint of the listbox.

listbox1.update();

listbox1.beginupdate(); // stop the listbox from drawing while items are added.

datatable dt;

int indexnum=listbox1.selectedindex;

dt=(datatable)listbox1.datasource;

datarow custrow = dt.rows[indexnum];

custrow.beginedit();

custrow[0] = indexnum;

custrow[1]="after modify";

custrow.endedit();

dt.acceptchanges();

listbox1.endupdate();// end the update process and force a repaint of the listbox.

listbox1.update();
