c# - ComboBox change depending on type of cell -

-

what want function fill comboboxpromoter using information data grid view in form.

basically should work this: if event type clubber, display promoter (names) eventtype (clubbing) combo box. else if event type exhibitor display promoters (names) related exhibitions.

the code below 1 combo box:

private void cmbpromoter_selectedindexchanged(object sender, eventargs e)     {         promoterform frm = new promoterform();          promoterbl pbl = new promoterbl();          if (txttype.text == "exhibition")         {         cmbpromoter.datasource = pbl.getpromotersbytype(frm.dgvpromoters.currentrow.cells[4].value.tostring());         cmbpromoter.refresh();         }         else if (txttype.text == "clubbing")         {          cmbpromoter.datasource = pbl.getpromotersbytype(frm.dgvpromoters.currentrow.cells[4].value.tostring());          cmbpromoter.refresh();         }

and class of promoter

 public list<advertiser> getpromotersbytype(string ptype)     {          eventticketentities database = new eventticketentities(); //always          return database.advertisers.where(p => p.promotertype.contains(ptype)).tolist();     }

maybe try datatemplateselector, it's simple use:
