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();
