Hi

I have a strange problem with the check.
As in the demo I load values but by a db
delphi code

.....
    LoadNodes(True);
   JQDynaTree.JQDynaTreeOptions.Checkbox:= True;
   JQDynaTree.ExpandAll;
.....
procedure TIWComponentForm.LoadNodes(const AFixed: boolean);
begin
  // Read value from db
  .....
// main nodes
                TreeNode:= JQDynaTree.Nodes.Add;
                descr := libutil.escapeChar(dm.OraQueryCeCoDett.FieldByName('NPADRE').Value);
                TreeNode.Title:= descr;
                TreeNode.ToolTip:= intToStr(dm.OraQueryCeCoDett.FieldByName('cFiglio').Value) + ' - ' +    dm.OraQueryCeCoDett.FieldByName('nPadre').Value;
                TreeNode.IsFolder:= True;
   .... 
// child nodes
               LoadChildren(TreeNode,NumNodes, dm.OraQueryCeCoDett.FieldByName('NPADRE').Value, dm.OraQueryCeCoDett.FieldByName('cfiglio').Value, dm.OraQueryCeCoDett.FieldByName('cPadre').Value, fold ,False, AFixed);
.......

end;

procedure TIWComponentForm.LoadChildren(AParentNode: TIWCGJQDynaTreeNode; const NumNodes: Integer; descr: String; cdc: Integer; cpadre:integer; fold:integer;  const AStopLoading: boolean; const AFixed: Boolean);
var
  TreeNode: TIWCGJQDynaTreeNode;
  I, ANumNodes: Integer;
begin
  for I := 1 to NumNodes do
  begin
    TreeNode:= AParentNode.Children.Add;
    if (fold > 0) then
      TreeNode.IsFolder:= True;
    TreeNode.Title:= descr;
    TreeNode.ToolTip:= intToStr(cdc) + ' - ' + descr;
    descr := libutil.escapeChar(descr);
    if (fold > 0) then  // fold is nr child eventually
      LoadChildrenChild(TreeNode,fold,True,AFixed);
  end;

end;

Dynatree work perfectly. Check works on all items but
JQDynaTree.SelectedNodes.Count is set only for the nodes and not the children

delphi code

procedure TJQDynaTreeFrame.IWCGJQButton3JQButtonOptionsClick(Sender: TObject; AParams: TStringList);
var
  I: Integer;
  s: string;
begin
  for I := 0 to JQDynaTree.SelectedNodes.Count-1 do
  begin
    s:= s + JQDynaTree.SelectedNodes[i] + '</br>';
  end;

end;

What's the problem?

Regards

The question is:

even if I read all of the nodes and their children, which property tells me if the item is checked?

any idea?

Hi Corwin,

I don't see any issue with SelectedNodes.
Please check the attached demo.

Best Regards.

Hi

I have not explained well.

in attachment you can see my example


I have to be able to select one or more child, but, in the example, IWCGJQDynaTree1.SelectedNodes.Count = 0; if instead Admin department is checked, IWCGJQDynaTree1.SelectedNodes.Count = 1 ...

another question is:
SOC AFFARI GENERAL is the DynaTree property TITLE, but the key relative in that DynaTree property is set?

Regards

Hi Corwin,

I don't know what is the problem in your side, but you can check our demo:

http://www.cgdevtools.com/demo/JQueryDemoV3_IW14_ISAPI.dll?frame=jqdynatree

Works as expected.
Maybe you can send us the simple testcase? T.I.A

SOC AFFARI GENERAL is the DynaTree property TITLE, but the key relative in that DynaTree property is set?

UniqueName property is auto generated, but you can set to your own (must be unique!).

Best Regards.
