后台更新DataTable行内容的方法

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();
