A key value.

Return Value:

Promise<any> (jQuery or native)

A Promise that is resolved after the data item is loaded. It is a native Promise or a jQuery.Promise when you use jQuery.

Angular

            }
        });
    }
}
@NgModule({

    // ...

        return fetch("http://mydomain.com/MyDataService?id=" + key);
    }
});

        return fetch("http://mydomain.com/MyDataService?id=" + key);
    }
});

class App extends React.Component {
    // ...
}
export default App;

cacheRawData

Specifies whether raw data should be saved in the cache. Applies only if loadMode is "raw".

Type:

Boolean

Default Value: true

Data caching allows the CustomStore to decrease the number of data requests. On the downside, cached data and data in your source may become out of sync. If keeping them synchronized is crucial in your scenario, disable data caching by setting the cacheRawData property to false. In this case, the CustomStore will send a request for data on every call of the load, byKey and totalCount functions.

Type:

Function

This function accepts a JavaScript Error object as the parameter.

    key: ['ProductID', 'ProductCode']
});

load

Specifies a custom implementation of the load(options) method.

Type:

Function

Function parameters:
options:

LoadOptions

Data processing settings.

Return Value:

Promise<any> (jQuery or native)

|

Array<any>

An array with data or a Promise that is resolved after data is loaded. It is a native Promise or a jQuery.Promise when you use jQuery.

This function's implementation has certain specifics depending on the UI component in which you use the CustomStore. Refer to the Custom Sources topic of a specific UI component for details:

See Also

loadMode

Specifies how data returned by the load function is treated.

Type:

String

Default Value: 'processed'
Accepted Values: 'processed' | 'raw'

Specify this property depending on the behavior you implemented for the load function. If this function sends data shaping properties to the server and fetches processed data, then loadMode should be "processed". If the load function simply fetches raw, unprocessed data from the server, set loadMode to "raw". In this case, the raw data will be processed on the client automatically.
