Hi,

 

At the moment, you can handle these events on the client side, using UniTreeView.ClientEvents

 

Best regards.

Hi,

 

Directly you would not find these events in uniTreeView however you can use following events of uniTreeView.ClientEvents

             - collapse

             - expand

Hi.

 

I can't fund clienevent, or I don't knpw how to use it.

 

I need expandall the treeview, but in every expand of a node I need to do something.

 

In an vcl app, with the treeview component standard of delphi, I write some code in the onexpand event of the node.

then I do tree.expandall, and that's all.

 

but in treevire of unigui, I don't know how to do this.

 

some help please.

 

thanks.

In ExtEvents Client Code: 

function beforerender(sender, eOpts)
{
   sender.addListener('afteritemexpand',
     function(node, index, item, eOpts) {
      ajaxRequest(sender,'expand',['id='+node.data.id]);
     });        
}

In ServerCode:

procedure TMainForm.TV1AjaxEvent(Sender: TComponent; EventName: string; Params: TStrings);
var
  i,id : integer;
begin
  if EventName='expand' then begin
    id:=StrToIntDef(Params.Values['id'],-1);
    for i:=0 to TV1.Items.Count-1 do begin
      if id=TWebTreeNode(TV1.Items[i]).Id then begin
        FillNode(TV1.Items[i]);
        Break;
      end;
    end;
  end;
end;

It will be similar code for collapse.
