I have a grid, wich is inside a tab with the key: "HotelsGrid". On my on row selection changed event, I need to disable the "HotelsGrid" tab, and enable and show the "HotelsEdit" tab with its content.

I am doing this, and before the migration from 11.1 to 13.2 it worked just fine:

uwtHotelsTab.Tabs.FindTabFromKey("HotelsGrid").Enabled = false;

uwtHotelsTab.Tabs.FindTabFromKey("HotelsEdit").Enabled = true;

uwtHotelsTab.SelectedIndex = uwtHotelsTab.Tabs.FindTabFromKey("HotelsEdit").Index;

 Now the tabs are not being enabled and disabled nor being changed.

Do I need to set something like "enable ajax" or something like that? here are my tabs:
