Dynamic Visibility Control of GridPanel Header in ExtJS

I have a GridPanel that needs to display a limited number of resources. If there are more resources available than what is currently shown, I would like the panel's header/title to indicate this by displaying text such as "more items available - display cut off."

My issue is: I know how to toggle the visibility of the header in the configuration options, but I am unsure how to change it at runtime, specifically after the grid's store has loaded a new set of records. This change should depend on whether the number of records loaded exceeds a certain maximum limit or not.

If possible, please provide answers that are compatible with Ext 2.x.

Thank you for your assistance!

Answer №1

Give this a try:

if (grid.rendered) {
    grid.header.hide();
    // grid.header.setStyle('display', 'none');
} else {
    grid.on('afterrender', function() {
        grid.header.hide();
        // grid.header.setStyle('display', 'none');
    }, grid, { single: true });
}

If your hideMode is set to visibility, use the code that is commented out (the one with setStyle).
