If set, this.context
will be set at runtime to the current value of the given Context.
Usage:
type MyContext = number
const Ctx = React.createContext<MyContext>(0)
class Foo extends React.Component {
static contextType = Ctx
context!: React.ContextType<typeof Ctx>
render () {
return <>My context's value: {this.context}</>;
}
}
Gets the actual scaling value used by the component to affect the pixel density of the control. A higher scaling ratio will produce crisper visuals at the expense of memory. Lower values will cause the control to appear blurry.

Called immediately before mounting occurs, and before Component#render
.
Avoid introducing any side-effects or subscriptions in this method.
This method will not stop working in React 17.
Note: the presence of getSnapshotBeforeUpdate or getDerivedStateFromProps prevents this from being invoked.
Called when the component may be receiving new props. React may call this even if props have not changed, so be sure to compare new and existing props if you only want to handle changes.
Calling Component#setState
generally does not trigger this method.

Called immediately before rendering when new props or state is received. Not called for the initial render.

Catches exceptions generated in descendant components. Unhandled exceptions will cause the entire component tree to unmount.
Called immediately after updating occurs. Not called for the initial render.
The snapshot is only present if getSnapshotBeforeUpdate is present and returns non-null.

Returns visuals as a serialized string.
Returns the sparkline visuals expressed as a SparklineVisualData object.
Runs before React applies the result of render
to the document, and
returns an object to be given to componentDidUpdate. Useful for saving
things such as scroll position before render
causes changes to it.
Note: the presence of getSnapshotBeforeUpdate prevents any of the deprecated lifecycle events from running.
Used to manually notify the IgxSparklineComponent that the data source has reset or cleared its items. Invoking this method is only necessary if that datasource is not observable.
Notify that the control has resized.
Provides a container to the sparkline control.
If using the new style context, re-declare this in your class to be the
React.ContextType
of yourstatic contextType
.static contextType = MyContext context!: React.ContextType<typeof MyContext>
if used without a type annotation, or without static contextType
