EXTJS 7.X Modern Kit Button Disabled

Question

I want to disabled an Export Button when the data not available in the grid.

Answer 1

Your grid should have a store set up that loads data? You could listen on your store for data changes.

listeners: {
        datachanged: function(store, eOpts) {
            //localize your button
            let yourButtonInToolbar,  //Get Button (e.g. via ComponentQuery)
                boolean = store.getData().getCount() === 0;

            yourButtonInToolbar.setDisabled(boolean);
        }
    }

In this event the store should already have set the data if changes occured. I did a boolean depending on the Output of the getCountmethod inside the result of the getData method on the store.

With this boolean I use the setDisabled method on the localized button in your toolbar.

I hope this helps.
