CanDrag(int)

Determines whether an item can be reordered by dragging mouse.

Declaration
public abstract bool CanDrag(int index)
Parameters
Type Name Description
int index

Zero-based index for list element.
Returns
Type Description
bool

A value of true if item can be dragged; otherwise false.
Remarks

This should be a light-weight method since it will be used to determine whether grab handle should be included for each item in a reorderable list.

Please note that returning a value of false does not prevent movement on list item since other draggable items can be moved around it.

CanRemove(int)

Determines whether an item can be removed from list.

Declaration
public abstract bool CanRemove(int index)
Parameters
Type Name Description
int index

Zero-based index for list element.
Returns
Type Description
bool

A value of true if item can be removed; otherwise false.
Remarks

This should be a light-weight method since it will be used to determine whether remove button should be included for each item in list.

This is redundant when HideRemoveButtons is specified.

Clear()

Clear all elements from list.

Declaration
public abstract void Clear()
