Name	Description
AfterUpdateItem	Called after an item update has been posted; performs any required post-update housekeeping.
DeleteItem	Locates and deletes the dataset record that corresponds to the specified kanban board item.
GetItems	Reads all records from the dataset and populates the kanban board columns with the corresponding items.
InsertItem	Appends a new record to the dataset for the specified kanban board item and writes its field values.
LoadItems	Clears the current kanban board items and reloads all records from the dataset.
ReadItem	Reads the dataset record that corresponds to the specified kanban board item and updates the item's properties.
SelectItem	Scrolls the dataset to the record that corresponds to the specified kanban board item.
UpdateItem	Locates the dataset record for the specified kanban board item and writes its current property values back to the dataset fields.

Events

Name	Description
OnColumnToFields	Occurs when a kanban board column index is about to be written to the dataset, allowing custom mapping from the column index to dataset fields.
OnFieldsToColumn	Occurs when a dataset record is read and the adapter needs to determine which kanban column the item belongs to; handle this event to provide custom column resolution.
OnFieldsToItem	Occurs when dataset fields are being read into a kanban board item, allowing custom field mapping from the dataset to the item.
OnItemCreateDBKey	Occurs when a new item is inserted and the adapter needs a unique key value; handle this event to supply a custom key instead of using the auto-generated one.
OnItemInserted	Occurs after a new item has been inserted into the dataset.
OnItemLocate	Occurs when the adapter needs to locate a specific dataset record for a kanban board item; handle this event to provide a custom locate strategy.
OnItemRead	Occurs after a kanban board item has been read from the dataset.
OnItemToFields	Occurs when an item is about to be written to the dataset, allowing custom field mapping from the kanban board item to dataset fields.
OnItemUpdated	Occurs after a kanban board item's changes have been posted to the dataset.
OnItemsLoaded	Occurs after all items have been loaded from the dataset into the kanban board.
