Namespace:

Dynamics.AX.Application

Assembly:

Deletes a specified item from a form list control.

public:
 virtual bool delete(int _Idx);

public virtual bool delete (int _Idx);

abstract member delete : int -> bool
override this.delete : int -> bool

Public Overridable Function delete (_Idx As Integer) As Boolean

Parameters

_Idx

Int32

The zero-based index for the item that is being deleted.

Remarks

The following example shows a call to the delete method to delete an item from the form list control. The while select statement retrieves account numbers from the CustTable table and then stores the data in a container. The items in the variable are added to the form list control by calling the FormListControl.addItem method.

        item = formListControl.addItem(formListItem); 
    } 
    // Delete an item. 
    itemDel = formListControl.delete(2);
