Toggling visibility of GridPanel header at runtime
I have a GridPanel which should load a maximum number of resources. If there are more resources available, than I want to show, I want to enable the panel's header/title to show some texte like "more items available - display cut off".
My problem is: I can set the header to be hidden oder shown in the config options, but how can I change the visibility at runtime, specificially just when the grid's store has loaded a new set of record, depending on whether the number of records loaded exceeds a certain maximum or not?
If possible, please give your answers compatible to Ext 2.x.
