Add New Row to a DataGrid in Silverlight WCF RIA Services -

-

some guidance silverlight wcf ria services... datagrid , detail view on same page 

control layout datagrid detail view [add new row (button)]

if wanted add new row button pick new row in datagrid how that?

i have tried:

detailviewtest.web.services.mode1domaincontext ctx =         (mode1domaincontext)worddomaindatasource.domaincontext;  word word = new word() {     word1 = this.word1textbox.text,     dateadded = datetime.now }; ctx.words.add(word); ctx.submitchanges();

this adds word database not datagrid though datasource data worddomaindatasource. if restart application shows in datagrid. great!

(using silverlight 4 business application starting project )

if you're using mvvm / inotifypropertychanged pattern need fire onpropertychanged event on itemsource.
