enable/disable sort header column menu in uniDBGrid

[bruno65]

Hi,

i tried to enable/disable sort header column menu in uniDBGrid with adding a checkbox named "Tri". For that i added a client event

function beforerender(sender, eOpts)
{
   var currentHeaders = this.headerCt.getMenu(); 
   
   // ajoute le menu pour le tri et le filtre
   currentHeaders.add(
      [
         {
            itemId: 'checkSortMenuItem',
            text: 'Tri', 
            checked: false, 
            handler: function() {
              currentHeaders.hide(true);
              ajaxRequest(sender, 'OnTriChange', ['checked='+this.checked.toString()]);
            }
         }
      ]
   );
}

and a server event 

procedure TMainForm.IUMGrid1AjaxEvent(Sender: TComponent; EventName: string;
  Params: TUniStrings);
var
  ShowFilter: Boolean;
  ShowSortOrder: Boolean;
  I: Integer;
begin
  if (EventName = 'OnTriChange') then
  begin
    ShowSortOrder := StrToBool(Params.Values['checked']);

    for I := 0 to IUMGrid1.Columns.Count - 1 do
      IUMGrid1.Columns.Items[I].Sortable := ShowSortOrder;

    IUMGrid1.Refresh;
  end;
end;

But the sort header column menu is always disabled even if the "Tri" checkbox is checked

So what is wrong in my code ?

Hello,

1 hour ago, bruno65 said:

currentHeaders.hide(true);

Why are you calling the hide method? And why do you need this behavior?

[bruno65]

i call 

currentHeaders.hide(true);

because if i don't do that the popup menu never disappears even if i click anywhere on the screen (with uniGUI 1.90.0 build 1568 Pro)

I'd like an checkbox in this popup menu for the user to enable or not sorting all columns (is disabled by default)
