[sajithkahawatta]

i want to delete a selected row from the database.the entries of
database is shown by a gridview and i do
<OnRowDeleting="GridView1_RowDeleting"> in source code.

i select and bind as follows.
[mycode]


string str = "select PNR,CreditCardNumber as 'Credit Card
Number',EmalAddress as 'Email Address',PassengerName as 'Passenger
Name',PassportNumber as 'Passport Number',IPNumber as 'IP Number' from
fraud_db order by PNR";
dbconn dc = new dbconn();


SqlConnection myConnection = new SqlConnection("Data
Source=IT0004493;Initial Catalog=IBE_fraud;User ID = sa ; password =
ecomtest ");//Trusted_Connection = yes;
myConnection.Open();
SqlCommand myCommand = new SqlCommand(str, myConnection);
SqlDataReader myReader = myCommand.ExecuteReader();


GridView1.DataSource = myReader;
GridView1.DataBind();


myReader.Close();
myConnection.Close();


[mycode]


now when i click on delete link it calls GridView1_RowDeleting(object
sender, GridViewDeleteEventArgs e) method


can i get the row entries of that row (i mean values of that row )
inside that method? i suppose to delete the row from db using that
entries of row using the query delete * from db where ....
(there is no primaty key in the table.)
is there any other easy way to delete a row from db selected in
gridview.
