Property Value

Type	Default	Description
String	String.Empty	A string value specifying the ID (or a list of IDs) of the web control or HTML element with which the popup menu is associated.

Remarks

Use the PopupElementID property to specify the web control or HTML element whose specific mouse action defined via the ASPxPopupMenu.PopupAction property invokes the current popup menu control. You can also specify a list of control IDs separated by the semicolon (;) sign.
