WPF中的DataGrid控件中增加数据
private void DataGrid1_DataGrid_RowEditEnding(object sender, DataGridRowEditEndingEventArgs e)
{
Employee employee = e.Row.DataContext as Employee;
if (e.EditAction == DataGridEditAction.Commit)
{
using (CQDBEXT DB = new CQDBEXT())
{
Employee matchedData = DB.Employee.SingleOrDefault(zl => zl.id == employee.id);
if (matchedData == null)
{
matchedData = new Employee();

DB.InsertOnSubmit(matchedData);

}

matcheData.name = employee.name;

DB.SubmitChanges();
}

}

运行后在datagrid中的空行输入数据，总是提示不能访问已释放的对象,请问如何解决？

当然了喽，你使用了
using (CQDBEXT DB = new CQDBEXT())
这样你在其范围外，该DB资源已经被释放掉了，你后面DB.SubmitChanges();还怎么提交修改啊？？？

皮之不存，毛将焉附!
