Active

Specifies whether the bind source adapter is active. Read Active to determine whether the bind source adapter is active. By default, the Active property is set to True. When Active is False, the bind source does not have an adapter or its adapter is not active. When Active is True, the bind source has an active adapter.

Type:

bool

ApplyUpdates()

Embarcadero Technologies does not currently have any additional information.

AutoActivate

Specifies whether the bind source is automatically activated. Set AutoActive to True for automatic activation.

Type:

bool

BOF

Indicates whether the bind source adapter is positioned in the first record. Read BOF (beginning of file) to determine if ItemIndex is located in the first record. If BOF is True, the bind source has an adapter and the active record is the first one. BOF is also True if there is no active record. BOF is False in all other cases.

Type:

bool

BindMethodsToEvents(prefix)

Connects methods to component events if they are named using the following pattern: Prefix_ComponentName_EventName. Example: def handle_button1_OnClick(Sender): pass The function returns a list of tuples. Each tuple contains the name of the component, the name of the event and the method object assigned to the event. Note that the prefix parameter is optional and will default to “handle_”.

CanModify

Specifies whether the bind source has permission to modify the data. Check CanModify to determine if data can be edited. When CanModify is set to True, the bind source can edit the data. When CanModify is set to False, the bind source cannot edit the data.

Type:

bool

Cancel()

Embarcadero Technologies does not currently have any additional information.

CancelUpdates()

Embarcadero Technologies does not currently have any additional information.

ComponentCount

Returns the owned component count

Components

Returns an iterator over the owned components

Delete()

Embarcadero Technologies does not currently have any additional information.

Edit()

Embarcadero Technologies does not currently have any additional information.

Editing

Indicates whether the data is in edit mode. Read Editing to determine whether the bind source adapter can currently edit the data. If the Editing property is True, the data provided by the bind source adapter is in editing mode. Otherwise, it is False.

Type:

bool

Eof

Indicates whether the bind source adapter is positioned in the last record. Read Eof (end of file) to determine if ItemIndex is located in the last record. If Eof is True, the bind source has an adapter and the active record is the last one or there are no records. Eof is False if the ItemIndex is located in any other position.

Type:

bool

First()

Embarcadero Technologies does not currently have any additional information.

GetFormatLink(AFieldName: str) → IEditFormatLink

Embarcadero Technologies does not currently have any additional information.

GetParentComponent()

Returns the parent of a component.

HasParent()

Indicates whether the component has a parent to handle its filing.

Insert()

Embarcadero Technologies does not currently have any additional information.

InternalAdapter

Returns the internal adapter of the bind source. The InternalAdapter property holds the internal adapter of the bind source. InternalAdapter uses the GetInternalAdapter method to return the internal adapter of the bind source.

Note: The GetInternalAdapter method always returns nil. Descendant classes must override this method to return the internal adapter.

Type:

BindSourceAdapter

IsRequired(AFieldName: str) → bool

Embarcadero Technologies does not currently have any additional information.

IsValidChar(AFieldName: str, AChar: unicodechr(str)) → bool

Embarcadero Technologies does not currently have any additional information.

ItemIndex

Specifies the index of the current record. ItemIndex holds the index of the current record of the dataset the bind source adapter is currently on. The first item has the index 0, the second item has the index 1, and so on. If no item is selected, the value of ItemIndex is -1.

Type:

int
