TdxBackendDataSetJSONConnection.AutoRefreshData Property

Specifies if the data connection component automatically refreshes data from associated datasets.

Declaration

property AutoRefreshData: Boolean read; write; default True;

Type	Default	Description
Boolean	True	Specifies if cached data is automatically updated from underlying datasets (TDataSet descendant instances): `True` Default. The data connection component automatically reloads and re-serializes data from associated datasets every time a TdxDashboard/TdxDashboardControl/TdxReport/TdxReportControl component starts to import data for design, preview, and export operations. You can call the TdxCustomDashboardControl.ReloadData procedure to reload and re-serialize data from associated datasets on demand. Note Data refresh operations may take a noticeable amount of time and have significant memory footprint depending on the number and size of associated datasets. `False` The data connection component loads and serializes data only once. No additional checks or data refresh operations are executed. TdxCustomDashboardControl.ReloadData procedure calls have no effect on the current data connection component. Tip This option may be useful if source data does not change at runtime.

You can set the AutoRefreshData property to False to speed up data population if source datasets remain unchanged during the current session.

You can call the following procedures to reload data and update content on demand when the AutoRefreshData property is set to True:

TdxCustomDashboardControl.ReloadData: Reloads data from all underlying data sources on demand and updates dashboard content.
TdxCustomReportControl.ReloadData: Reloads data from all underlying data sources on demand and updates report content.

The AutoRefreshData property’s default value is True.
