SYMPTOMS
Disabling a ComboBox list item by using the This.List(This.ListItemId)='\' method causes the disabled item to disappear when the RowSourceType is either STRUCTURE or VALUE.



RESOLUTION
Use the following statement, and ensure that the DisabledItemForeColor and DisabledItemBackColor properties display the item properly: This.List(This.ListItemId)="\"+This.List(This.ListItemId)



STATUS
Microsoft is researching this behavior and will post new information here in the Microsoft Knowledge Base as it becomes available.



Steps to Reproduce Behavior
Example One:  Create a Form with a combo box (with a style of DropDown Combo).  In the DblClick method of the combo box, place this code: This.List(This.ListItemId)='\'   In the RowSource for the combo box, place this code: customer && This the \Samples\Data\Customer.dbf  In the RowSourceType for the combo box, select 8 - STRUCTURE. Run the Form, and select an item on the list. When the item appears in the combo box, double-click to disable the item. Scroll through the list to see that the item is not visible.</ol>

Example Two: <ol>  In the DblClick method of the combo box, place this code: This.List(This.ListItemId)='\'+ This.List(This.ListItemId) </li> Rerun the Form. The disabled item remains visible with the DisabledItemForeColor and DisabledItemBackColor properties.</li></ol>
