Optional UNSAFE_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.
16.3, use componentDidMount or the constructor instead
Optional UNSAFE_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.

Note: the presence of getSnapshotBeforeUpdate or getDerivedStateFromProps prevents this from being invoked.
16.3, use static getDerivedStateFromProps instead
Optional UNSAFE_Called immediately before rendering when new props or state is received. Not called for the initial render.

Clears grouping for particular column, array of columns or all columns.
Clears all grouping in the grid, if no parameter is passed. If a parameter is provided, clears grouping for a particular column or an array of columns.
this.grid.clearGrouping(); //clears all grouping
this.grid.clearGrouping("ID"); //ungroups a single column
this.grid.clearGrouping(["ID", "Column1", "Column2"]); //ungroups multiple columns
name Name of column or array of column names to be ungrouped.
Collapses the row by its id.
ID is either the primaryKey value or the data record instance.
this.grid.collapseRow(rowID);
rowID The row id - primaryKey value or the data record instance.
Optional componentOptional componentCalled immediately after updating occurs. Not called for the initial render.
The snapshot is only present if getSnapshotBeforeUpdate is present and returns non-null.
Optional componentCalled immediately before mounting occurs, and before Component#render.

returns an object to be given to componentDidUpdate. Useful for saving
things such as scroll position before render causes changes to it.

Returns if a group is expanded or not. group The group record.
public groupRow: IGroupByRecord;
const expandedGroup = this.grid.isExpandedGroup(this.groupRow);
Triggers change detection for the IgxGridComponent.
Calling markForCheck also triggers the grid pipes explicitly, resulting in all updates being processed.
May degrade performance if used when not needed, or if misused:
// DON'Ts:
// don't call markForCheck from inside a loop
// don't call markForCheck when a primitive has changed
grid.data.forEach(rec => {
rec = newValue;
grid.markForCheck();
});
// DOs
// call markForCheck after updating a nested property
grid.data.forEach(rec => {
rec.nestedProp1.nestedProp2 = newValue;
});
grid.markForCheck();
grid.markForCheck();
Opens the advanced filtering dialog.
Selects all rows

Static _create
If using the new style context, re-declare this in your class to be the
React.ContextTypeof yourstatic contextType. Should be used with type annotation or static contextType.
