從MS Access數據庫和Gridview Winforms完全刪除Devexpress？

Question

我可以能夠刪除所選行中的GridView暫時的，當我再次打開相同的形式再次使用此代碼

gridview1.DeleteselectedRows(); 

顯示所有的行，但我需要從數據庫完全刪除也，所以，我想這個代碼但是這段代碼從gridview中刪除了選定行的下一行或選定行的前一行。這段代碼有什麼問題？

gridview1.DeleteselectedRows();               object temp = gridView1.GetFocusedRowCellValue("InvoiceNumber"); 

validateDept.InitializeConnection(); 
OleDbConnection con = new OleDbConnection(validateDept.connetionString); 
con.Open(); 
OleDbCommand delete1 = new OleDbCommand("delete from NewInvoice_1 where InvoiceNumber=" + temp, con); 
OleDbCommand delete2 = new OleDbCommand("delete from NewInvoice_2 where InvoiceNumber=" + temp, con); 
delete1 .ExecuteNonQuery(); 
delete2 .ExecuteNonQuery(); 
con.Close(); 

Answer 1

validateDept.InitializeConnection(); 
OleDbConnection con = new OleDbConnection(validateDept.connetionString); 
con.Open(); 
OleDbCommand delete1 = new OleDbCommand("delete from NewInvoice_1 where InvoiceNumber=" +  temp, con); 
OleDbCommand delete2 = new OleDbCommand("delete from NewInvoice_2 where InvoiceNumber=" + temp, con); 
delete1 .ExecuteNonQuery(); 
delete2 .ExecuteNonQuery(); 
con.Close(); 

不要先寫gridview1.DeleteselectedRows();這條線，因爲它刪除的GridView &跳轉到下一行則數據庫會刪除下一行選定的行，所以會出現問題。
