我將一個DataSet放到一個Session中，將Session中的一個表綁定到一個DataGrid中，在DataGrid中我加入了模板列。
DataSet表的示例：

字段1	字段2	字段3	刪除標記
ID1	姓名1	地址1	已經刪除
ID2	姓名2	地址2
ID3	姓名3	地址3

當用戶通過DataGrid模板列刪除第一條記錄后，此時數據并未保存到數據庫中，只是在第一條記錄中做了一個刪除標記。但在DataGrid中用戶看到的第一條記錄已經沒有了，模板列綁定的第一條記錄實際上是DataSet中的第二條記錄，當用戶再次執行刪除DataGrid中的第一條記錄時，通過參數獲得的仍然是已經刪除的第一條記錄的rownumber，所以執行后不會在DataGrid中刪除。

問題終于解決了，由于我是使用Row.Delete()函數，數據并未從數據集中刪除，只是做了一個刪除標記，所以在提取數據時，需要計算DataGrid中要刪除行中數據在DataSet中具體是對應的那條。函數如下：

??private?int?GetFactRowItem(DataTable?table,int?ItemIndex)
??{
???int?FactRowItem=0;
???int?UnDeleteRowCount=-1;
???while(UnDeleteRowCount<ItemIndex)
???{
????if(table.Rows[FactRowItem].RowState==DataRowState.Deleted)
????{
?????FactRowItem++;
????}
????else
????{
?????FactRowItem++;
?????UnDeleteRowCount++;
????}
???}
???return?FactRowItem-1;
??}?
