Stack Overflow works best with JavaScript enabled.The ScrollView is a generic scrolling container that can contain multiple components and views. The scrollable items need not be homogeneous, and you can scroll both vertically and horizontally by setting the horizontal property.

This example creates a vertical ScrollView with both images and text mixed together. ScrollViews can be configured to allow paging through views using swiping gestures by using the pagingEnabled props.

Maintaining scroll positions in all browsers

Swiping horizontally between views can also be implemented on Android using the ViewPager component. On iOS a ScrollView with a single item can be used to allow the user to zoom content. Set up the maximumZoomScale and minimumZoomScale props and your user will be able to use pinch and expand gestures to zoom in and out.

The ScrollView works best to present a small amount of things of a limited size. All the elements and views of a ScrollView are rendered, even if they are not currently shown on the screen. If you have a long list of more items than can fit on the screen, you should use a FlatList instead.

The virtual table contains only the rendered rows; others are replaced with two stub rows whose heights depend on the estimatedRowHeight property value and change dynamically as the user scrolls.

You can change the virtual table's height using the height property. To scroll the table to a particular row, call the scrollToRow method and pass the row ID as its parameter. To call the method, you need the VirtualTable plugin's ref. In the following demo, the scrollToRow method is used to scroll the table to a new or saved row. When you add a new row, it is added to the top of the table, and the table is scrolled to it.

When you save the row, its position is changed according to sorting, and the table is scrolled to that position. NOTE: Scrolling to a row cannot be used with lazy loading. This is because the Grid loads rows in parts in lazy loading mode, and scrolling to a row requires all the row IDs. If you use a custom rowComponent or cellComponentits height and the estimatedRowHeight value should be equal.

The same applies to a custom formatter defined in the DataTypeProvider plugin.

In case you're interested by making you're constructor more dry you could also use the ES6 fat arrow syntax. Fat arrow automatically bind this to the method, allowing shorter constructor. Especially when you have a lot of methods. Note however that input events and animation frames are fired at about the same rate and therefore the optimization below is often unnecessary.

Hi jylopez This is what I needed. Appreciated the ES6 tip from EEtancelin. I like not having to add the bindings in the constructor. Good stuff! Good stuff jylopez.

Imagine you have a very long list of items you want to display, maybe several screens worth of content. Creating JS components and native views for everything all at once, much of which may not even be shown, will contribute to slow rendering and increased memory usage. This is where FlatList comes into play. FlatList renders items lazily, when they are about to appear, and removes items that scroll way off screen to save memory and processing time.

FlatList is also handy if you want to render separators between your items, multiple columns, infinite scroll loading, or any number of other features it supports out of the box.

SWR scales extremely well because it requires very little effort to write applications that automatically and eventually converge to the most recent remote data. In many cases, applying local mutations to data is a good way to make changes feel faster — no need to wait for the remote source of data. Local mutations are a completely optional way to set a temporary local state that will automatically update on the next revalidation.

However, the developer can define any asynchronous function as the fetcher. For example, GraphQL:. SWR allows you to fetch data that depends on other data.
