VB.NET Refresh other DataGridView based if changing in another DataGridView -


i habe datagridview shows attributes of employees. can add remove, save, works quite fine. in same form have datagridview shows employeegroups employees belong. datamodel this: tableemployees.pk --> table employeegroups fk employeenr --> employeenr

now tried several ways (it feels hundreds) refresh second datagridview. because wanted possibility test bit easier code in buttonevent change it, if works.

here datacollections:

 t_magruppentableadapter.fill(dtmagruppen)  tmagruppenbindingsource.datasource = dtmagruppen

out of names can see types.

here how fill datagridview:

 private sub datagridmagruppen_fill()     ' set datagridview.      dim mitarbeiternr, gruppennr new datagridviewcomboboxcolumn      me.datagridmagruppen         .autogeneratecolumns = false         .datasource = db.tmagruppenbindingsource         .autosizerowsmode = _             datagridviewautosizerowsmode.displayedcellsexceptheaders         .borderstyle = borderstyle.fixed3d         .editmode = datagridvieweditmode.editonenter     end     me.datagridmagruppen.columns          mitarbeiternr             .datapropertyname = "mitarbeiternr"             .datasource = db.tmitarbeiter2bindingsource             .displaymember = "nn"             .valuemember = "nr"             .flatstyle = system.windows.forms.flatstyle.flat             .headertext = "mitarbeiter"             .width = 193         end         gruppennr             .datapropertyname = "gruppennr"             .datasource = db.tgruppenbindingsource             .displaymember = "gruppename"             .valuemember = "nr"             .flatstyle = system.windows.forms.flatstyle.flat             .headertext = "gruppe"             .width = 190         end         .addrange(mitarbeiternr, gruppennr)     end  end sub

and here tries refresh datagridview:

    db.tableadapterspeichern(1)     db.tmagruppenbindingsource.resetbindings(false)     'db.dtmagruppen.clear()     'db.t_magruppentableadapter.fill(db.dtmagruppen)     'datagridmagruppen.datasource = db.dtmagruppen

the dataadapters etc. have prefix because made database class.

so how can refresh datagridview magruppen after update datagridviewemployees?

*edit add method tableadapterspeichern

   public sub tableadapterspeichern(byval typ integer)      dim test integer      select case typ         case 1      'person              tmitarbeiterbindingsource.endedit()             test = t_mitarbeitertableadapter.update(ctype(tmitarbeiterbindingsource.datasource, datatable))         case 2      'kfz             tkfzbindingsource.endedit()             t_kfztableadapter.update(ctype(tkfzbindingsource.datasource, datatable))         case 3  'gruppen             tmagruppenbindingsource.endedit()             t_magruppentableadapter.update(ctype(tmagruppenbindingsource.datasource, datatable))         case 4      'person             tmitarbeiter1bindingsource.endedit()             t_mitarbeiter1tableadapter.update(ctype(tmitarbeiter1bindingsource.datasource, datatable))     end select  end sub

i can add new employees , everything, should work, type use save employees 1.

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...
