JavaScript/jQuery Diagram - DiagramShape

When a user pastes or clones several items in a diagram, the control adds the items to the model one by one. For each added item, the requestEditOperation event fires. In the event handler, you can access the processed item. However, if you call the getItemById(id) method to access an attached connector, you can get the undefinedresult if the item is not added to the model yet.

Use the containerChildItemIds property to get identifiers of shapes stored in a horizontalContainer or verticalContainer shape. If the container stores no shapes or the shape is not a container, the property returns an empty string

When a user pastes or clones several items in a diagram, the control adds the items to the model one by one. For each added item, the requestEditOperation event fires. In the event handler, you can access the processed item. However, if you call the getItemById(id) method to access a container's child item, you can get the undefinedresult if the item is not added to the model yet.

This property is in effect for horizontalContainer or verticalContainer shapes. If the shape is not a container, its containerExpanded property always returns true.

Use the containerId property to get the identifier of the container (a shape of the horizontalContainer or verticalContainer type) that stores the shape. The containerChildItemIds property allows you to get identifiers of shapes stored in the container.

If a user removes an item and then undoes the action, the Diagram inserts the item back and generates a new GUID for its key value. A new GUID is also generated for pasted and cloned items. If you specify key values (IDs in a data source) manually, subscribe to the onInserting data source event to assign the values.
