Row not found or changed

Row not found or changed

Postby ferroariel » Wed 03 Apr 2013 23:46

I know this is a very common issue on LinqConnect, but I´m going insane.

Check this simple code

Code: Select all
TktSoporteDataContext dc2 = new TktSoporteDataContext();                   
TTiket pepito = dc2.TTikets.FirstOrDefault(a => a.TNUMERO.ToString().Equals(e.CommandArgument.ToString()));
dc2.TTikets.DeleteOnSubmit(pepito);
dc2.SubmitChanges(ConflictMode.ContinueOnConflict);


Always get the very same error: "Row not found or changed"

Row not found or changed.

I tried everything
- putting each column on UpdateCheck=Never
- using a different datacontext instead of the one being used on page (see "dc2")
No luck at all, I´m very depressed at this time.

WHAT IS HAPPENING ?????

To be clear on this,
The code is fired by a row command action from a gridview
I tried this simple code so I guess nobody may argue that "any other person has changed the record..." and that stuff

Could you please send us a sample project with which this issue could be reproduced.

JIC: the DbLinqDataSource component can perform deletions automatically, without using the OnRowCommand event. Please try using this functionality and inform us whether DbLinqDataSource deletes rows properly.
