OnClick for SubMenu Items

[zsleo]

First time I am using Vertical Menu.

How do I find the the tag value for SubMenu Item clicked?

For example below the top level items all work okay but lv_ItemV is always nil for SubItems:

procedure TiwfrmMain.iwcgjqvrtmnMainMenuJQVertMenuOptionsClick(Sender: TObject; AParams: TStringList);
var
lv_I: Integer;
lv_ItemV: TIWCGJQVertMenuItem;
begin
lv_ItemV := iwcgjqvrtmnMainMenu.Items.GetByUniqueName(AParams.Values['itemId']);
if lv_ItemV = nil then
Exit;

lv_I := lv_ItemV.Tag;

end;


TIA

Hi zsleo,

GetByUniqueName

Please use GetItemByUniqueName instead.
GetByUniqueName method fixed in next beta build.
Thanks.

Best Regards.

Is this in the net release?

Hi zsleo,

Sorry for misinformation.

Thanks.

Hi amirreza_asadpour,

Basically, you need assign the JQVertMenu.OnClick event, and then, in event check the AParams parameter, you will find the itemId.

If you need to get the item, use the GetByUniqueName method.

Also, you can check the source of JQueryDemoV3_IW14 demo.

Best Regards.

I have recently upgraded to Delphi 10.2.3 (from XE), IW 14.2.27 and CGD 4.1.0.50 (from 4.1.0.31)

I have a Vertival menu that is created at runtime and popolated from a DB Query.

The code that was working previously is now not working.

The problem code is that no longer working is occurs once the selected menu item with item-index greater than 15 and or the selected menu item is in a sub-menu with sub-menu item-index above 0

Code: Select all

  lv_itemId := AParams.Values['itemId']; {<<== returning 'IWCGJQVRTMNMAINMENU_1_3' which is what is expected}
  lv_I := -1;

  try
    lv_I := iwcgjqvrtmnMainMenu.Items.GetByUniqueName(lv_itemId).Tag; {<<== line 1033}
  except
    UserSession.LogToFile('M Not Exist: ' + AParams.Values['itemId']);
    Exit;
  end;


The GetByUniqueName at line 1033 is throwing an exception. Here is the stack dump:

Hi zsleo,

I've checked here, and works as expeceted.

Can you send me the simple testcase, which will reproduce that?

Best Regards.
