Bindingsource Find method
in [Compact Framework]
|
From: Mark Huisinga on 21 Jun 2006 10:40 Bindingsource.find(..) doesn't seem to work on a bindingsource with as datasource a sqlceresultset.resultview. As far as I can tell this is odd since the sqlceresultset.resultview does implement IBindingList. Or is this a limitation of the compactframework ? Mark.
From: Ginny Caughey [MVP] on 21 Jun 2006 11:22 Mark, I think it's probably a limitation of the SqlCeResultSet since it doesn't contain the actual data and only maintains pointers to the data (unlike DataSet). Similarly Sort is also not supported I believe. -- Ginny Caughey ..NET Compact Framework MVP "Mark Huisinga" <mhuisinga(a)newsgroups.nospam> wrote in message news:_Tcmg.19470$UQ2.9875(a)beryl... > Bindingsource.find(..) doesn't seem to work on a bindingsource with as > datasource a sqlceresultset.resultview.

From: Mark Huisinga on 21 Jun 2006 11:56 Ginny, Ok, that is too bad. I have tried to achieve something similar by using the sqlceresult seek method, however I then have no idea of how to update the bindingsource so that my controls show the correct record. Is this at all possible ? thanx, Mark "Ginny Caughey [MVP]" <ginny.caughey.online(a)wasteworks.com> schreef in bericht news:u$MjhaUlGHA.3816(a)TK2MSFTNGP02.phx.gbl... > Mark, > > I think it's probably a limitation of the SqlCeResultSet since it doesn't > contain the actual data and only maintains pointers to the data (unlike > DataSet).

From: Ginny Caughey [MVP] on 21 Jun 2006 12:45 Mark, Probably the best way would be to set the BindingSource.DataSource to null, then set it back to your new resultset. -- Ginny Caughey ..NET Compact Framework MVP "Mark Huisinga" <mhuisinga(a)newsgroups.nospam> wrote in message news:6%dmg.22179$UQ2.2647(a)beryl... > Ginny, > > Ok, that is too bad.

Ginny, I tried that, but setting the bindingresource to null resulst in an ArgumentException without an errormessage ( the source assembly cannot be found).
