Timeout on populating a datagrid

P: n/a
I sometimes get a timeout error when populating my datagrid,

the code is
WizardConnection.Open()

UpdateCommand.CommandText = "EXECUTE sp_assign_user '" &
PhysOffice.SelectedValue & "', '" & Context.User.Identity.Name & "'"

UpdateCommand.ExecuteNonQuery()

WizardConnection.Close()
Any suggestions?
Thanks
Paul

Hi Paul:

It doens't look like the problem is DataGrid related, but in the
stored procedure you use to update a record in the database.

I'd review the stored procedure SQL in a query tool and see how long
the query is taking. Perhaps the stored procedure is trying to update
a record in a large table and does not have an index available to find
the record quickly.

HTH,

The sproc is reading not updating any database, depending upon the selection
criteria the sproc can take upto 30 seconds to complete, but asp.net doesn't
seem to want to wait that long.

You could set a longer timeout but that's already quite long. I would check
first if it makes sense it take so much time. How many records are returned
?

Hi Paul:

Sorry for the confusion, the source code you posted shows
ExecuteNonQuery, but the stack trace shows the exception occurs on a
Fill method.

The CommandTimeout property of an OleDbCommand object defaults to 30
seconds. Seems possible it could occasionally be going over.
One approach would be to look at ways to speed up the query, and
check for locking and blocks in the database. Another approach would
be to bump the CommandTimeout property up to a number where the query
can always safely complete.
