Hi,

I have a little problem with NxComboBox.
I want to have an autocomplete CBox, but I dont know how to make it.

I'm using last version of the component on D7.

Hello Bleu,

This option doesn't exist yet, but you may use NxAutoCompletion component (NxAddonsRun.dpk package) and attach auto-completion list to the ComboBox.

More info about NxAutoCompletion components:

I hope that this helps.

Hello PCBleu,

In future I will add similar property to NxComboBox, but please note that this can take a while.

Hello PCBleu,

You will need to add similar code:

CODE

procedure TForm1.Button1Click(Sender: TObject);
var
  i: Integer;
begin
  NxAutoCompletion1.Strings.Clear;
  for i := 0 to NxComboBox1.Items.Count - 1 do
  begin
    NxAutoCompletion1.Strings.Add(NxComboBox1.Items[i]);
  end;
  NxAutoCompletion1.Associate := NxComboBox1;
  NxAutoCompletion1.Enabled:= True;
end;

This code will copy a content from NxComboBox and move it to Strings property of NxComboBox.

I hope that this helps

Best regards

Hello,

New questions about autocomplete, with last version installed
I find new NxComboBox properties such as AutoComplete, AutoCompleteDelay and AutoDropDown...

I did not reach to find a way to use correctly these properties...
I am very interested in using AutoComplete property for DropDown or DropDownList NxComboBox

Thanks for any help or advise

[Boki (Berg)]

Hello PCBleu,

Try to set AutoComplete to true and then add several items in Items property. When you type item that begins with letters same as in Items property, drop-down string will appear.

AutoDropDown when set to True opens a pop-up list as when you type any letter.

I suggest that you add some dummy items and you will understand all very soon

I hope that this helps.

Thanks for your answer

in fact, I just use NxComboBox with "DsDropDownList" Style
and when I type any character, just the first character of an item can change the selection

for example with items like "Alemania, Argentina, Francia..."
and with a DsDropDownList style
when I type "F", this will select "Francia", and if I type "A", it just select "Alemania"
with no effects with further "A" typed

Is there a possibility to correct this problem

Thanks in advance

Hello PcBleu,

This is happening because Style is set to DropDownList. Unfortunately this is how it works.

Thanks for your answer

in fact I use this style, because I want to limit the selection within the items listed in the box

is there a way to limit the text introduced by the user

Hello,

You may access to OnKeyPress event of the Grid:

CODE

procedure TForm1.NextGrid1KeyPress(Sender: TObject; var Key: Char);
begin
  if gtEdit in NextGrid1.GridState then
  begin
    if Key = '-' then Key := #0;
  end;
end;

This code will disable typing - char.

It is important to use

CODE

  if gtEdit in NextGrid1.GridState then

You may access to the Editor property of Column, or access to the InplaceEdit property of NextGrid too.

Best regards
