AutoRefresh

  • Last UpdatedNov 17, 2021

The AutoRefresh property is a read-write property that enables or disables automatic refresh of the data in the aaHistClientActiveDataGrid.

Syntax

aaHistClientActiveDataGrid.AutoRefresh = discrete;

Result = aaHistClientActiveDataGrid.AutoRefresh;

Remarks

True = Automatic refresh on; False = Automatic refresh off.

The default value is False.

Automatic refresh works by periodically calling the Execute method. The time interval is based on the RefreshFrequency property. The default time interval is 60 seconds.

The AutoRefresh property is set to False if the last manual call to the Execute method failed. If the AutoRefresh property is set to True, and for some reason later fails, it is automatically set to False, and the aaHistClientActiveDataGrid is reset (cleared).
