Hot to get JQMMobiScroll2 selected values (treelist)

[ali]

Hi, working with JQMobiScroll2demo, i´m trying to get the selected values without analizing AParams text. Is it possible?
I'm using the IWCGJQMMobiScroll215, having Treelist presets.

Here's is the code with the problems in the comments

Code: Select all

procedure TIWForm2.IWCGJQMMobiScroll215JQMCoreOptionsSelect(Sender: TObject;
  AParams: TStringList);
var i, j, k : integer;
    v1, v2, v3 : string;
begin
  for i := 0 to TIWCGJQMMobiScroll2TreeListOptions(IWCGJQMMobiScroll215.PresetOptions).Items.Count -1 do
  begin
    // selected is allways False
    if TIWCGJQMMobiScroll2TreeListOptions(IWCGJQMMobiScroll215.PresetOptions).Items[i].Selected then
    begin
      v1 := TIWCGJQMMobiScroll2TreeListOptions(IWCGJQMMobiScroll215.PresetOptions).Items[i].Value;
      break;
    end;
  end;
  // value is allways ''
  IWCGJQMLabel2.Text := IWCGJQMMobiScroll215.JQMCoreOptions.Value;
  // IWCGJQMMOBISCROLL215_JQM_DATA=America V Brazil v Sao Paolo v
  AParams.SaveToFile('params.txt');
  {
  AParams
  Here i can find the selected items
  IWCGJQMMOBISCROLL215_JQM_DATA=Asia Japan Kagoshima
  IW_TrackID_=1
  callback=IWCGJQMMOBISCROLL215.DoAjaxRequest
  ajaxevent=JQMCoreOptions.OnSelect
  ComponentName=IWCGJQMMobiScroll215
  }
end;

Hi, perhaps the question is not clear enough.

I'm testing treelist preset.
I want to know where the selected values are stored in JQMMobiScroll2.
The selected property of the items is false and JQMCoreOptions.Value is empty.

Thank you.

Try:

Code: Select all

JQMMobiScroll2.PresetTreeListOptions.SelectedItem

Hi Alex,

It´s a protected property, i can't use it.

protected
property SelectedItem: TIWCGJQMMobiScroll2TreeListItem read GetSelectedItem;
