TTMSFNCDataGridDatabaseAdapter.AutoRemoveColumns Property

When True (default), the column mappings and grid columns are removed when the dataset closes or the data source is disconnected.

API unit family: TMSFNCDataGridDatabaseAdapter Declaring type: TTMSFNCDataGridDatabaseAdapter Inherited from: TTMSFNCCustomDataGridDatabaseAdapter Type: Boolean

Syntax

FMX.TMSFNCDataGridDatabaseAdapter.hppPascalC++

property AutoRemoveColumns: Boolean;

__property bool AutoRemoveColumns = {read=FAutoRemoveColumns, write=FAutoRemoveColumns, default=1};

Default: True

Remarks

When the dataset closes (and KeepData is False), the whole Columns collection is cleared only if it contains no explicitly defined fields (see TTMSFNCDataGridDatabaseAdapterColumns.HasFieldsDefined); when no data source or dataset is linked any more, it is cleared regardless. Nothing is removed while the form is loading.
