UniComboBox - remote query with fixed list

UniComboBox  -remote query with fixed list

 

Hello Farshad ,   there is a way to prevent  bad input or errors?  For ex: DevExpress cxDBLookupCombobox can sets the DropDownListStyle to lsFixedList for avoid user input of casual value in combo editor..

 

Is this possible with uniComboBox with remote query? I want that ONLY correct values  can be typed; if i add some "not found" chars, edit value must revert to latest right value. 

 

Best regards.

Hi,

About what?!

[rgreat]

UniCombobox with remote query where you can only select items from list.

I'd like to get UniCombobox.itemindex working with remote query enabled. Not working for me now.

And also like to auto-revert user typed input when i exit UniCombobox if no item is selected.

So to summarise i'd like to have UniCombobox with csDropDownList itemindex behaviour but with option to search through it like on csDropDown+remote query.

Hi,

Can you make a simple testcase for this?..

procedure TMainForm.UniComboBox1RemoteQuery(const QueryString: string; Result: TStrings);
var
  i: Integer;
begin
  Result.Clear;
  for i:=1 to 9 do begin
    Result.Add(i.ToString);
  end;
end;

1.

 

2.

 

Even if you change UniCombobox.Style to csDropDownList nothing will change. 

ItemIndex will still be -1.

This make impossible to reliably select item in list unless you fallback to dirty tricks like adding ID in listbox item text.

Try ajaxRequest.

UniCombobox -> ClientEvents -> ExtEvents -> beforeselect :

function beforeselect(combo, record, index, eOpts)
{
  ajaxRequest(combo,'bselect',['index='+index]);
}

UniCombobox -> OnAjaxEvent :

procedure TMainForm.UniComboBoxAjaxEvent(Sender: TComponent;
  EventName: string; Params: TUniStrings);
begin
  if SameText(EventName,'bselect') then
  begin
    self.ShowToast(Params.Values['index']);
  end;
end;

Thank you.

It would be nice if this bug would be fixed, though.
