useUnselectAll
This hook returns a function that unselects all lines in a <DataTable>.
Usage
import { useListContext, useUnselectAll } from 'react-admin';
const UnselectAllButton = () => {
const { resource } = useListContext();
const unselectAll = useUnselectAll(resource);
const handleClick = () => {
unselectAll();
};
return <button onClick={handleClick}>Unselect all</button>;
};
Parameters
useUnselectAll accepts two parameters. Both are optional:
resource: The resource name. If not specified, the hook will only update the locally stored selection state (changes are not persisted in the Store).storeKey: The store key to use. If not specified, the hook will derive the store key from theresource. It should match with thestoreKeyused in the parent<List>.
resource
Use resource to specify the resource name.
import { useListContext, useUnselectAll } from 'react-admin';
const UnselectAllButton = () => {
const { resource } = useListContext();
const unselectAll = useUnselectAll(resource);
const handleClick = () => {
unselectAll();
};
return <button onClick={handleClick}>Unselect all</button>;
};
If not specified, the hook will only update the locally stored selection state (changes are not persisted in the Store). This is notably useful when the parent <List> has the storeKey prop set to false.
import { useListContext, useUnselectAll } from 'react-admin';
const UnselectAllButton = () => {
// Call useUnselectAll without arguments - local selection only
const unselectAll = useUnselectAll();
const handleClick = () => {
unselectAll();
};
return <button onClick={handleClick}>Unselect all</button>;
};
storeKey
The default store key is derived from the resource name: ${resource}.selectedIds.
You can customize the store key used by passing a storeKey parameter to the hook. Make sure it matches the storeKey used in the parent <List>.
The final store key used will be ${storeKey}.selectedIds.
import { useListContext, useUnselectAll } from 'react-admin';
const UnselectAllButton = () => {
const { resource } = useListContext();
const unselectAll = useUnselectAll(resource, 'customStoreKey');
const handleClick = () => {
unselectAll();
};
return <button onClick={handleClick}>Unselect all</button>;
};
Return value
useUnselectAll returns a function taking one optional parameter:
fromAllStoreKeys: A boolean indicating whether to unselect the records across all storeKeys used with this resource. Defaults tofalse. Set this totruefor instance when the records are deleted, to ensure they donβt remain selected in other lists.
import { useListContext, useUnselectAll } from 'react-admin';
const UnselectAllButton = () => {
const { resource } = useListContext();
const unselectAll = useUnselectAll(resource);
const handleClick = () => {
// Unselect across all store keys
unselectAll(true);
};
return <button onClick={handleClick}>Unselect all</button>;
};
