**DeserializeValue, VIRTUAL**

{{blk2blue.jpg|blk2blue.jpg}}

The **DeserializeValue **virtual** **method extracts values (separated by the value of the **Delimiter** property) from the EIP columns USE variable (UseVar) and preloads the items into the **Selected** queue. **DeserializeValue** will split the **SELF.UseVar** contents using the **SELF.Delimiter** value as a separator, and store the resulting values to the **Selected** queue if values are in the available list. Any value that is not in the available list is discarded.

**Implementation:**

The **DeserializeValue** method is called before opening the MultiSelect dialog window from within the **TakeEvent** method of the EditMultiSelectClass.

**Example:**

**EditMultiSelectClass.TakeEvent PROCEDURE(UNSIGNED E)**

**MSWindow MSWindowClass**

**MSSelectedIndex LONG**

** CODE**

** CASE E**

** OF EVENT:DroppingDown**

**   IF SELF.Delimiter**

**    FREE(SELF.Selected)**

**   ****SELF.DeSerializeValue()**

**   END**

**   MSWindow.Init(SELF)**

**   OPEN(MultiWindow)**

**   0{PROP:Text} = SELF.Title**

**   ?Available{PROP:From} = SELF.Available.Item**

**   ?Available{PROP:Mark} = SELF.Available.Mark**

**   ?Selected{PROP:From} = SELF.Selected.Item**

**   ?Selected{PROP:Mark} = SELF.Selected.Mark**

**  IF SELF.ReadOnly**

**    DISABLE(?SelectSome)**

**    DISABLE(?SelectAll)**

**    DISABLE(?DeselectSome)**

**    DISABLE(?DeselectAll)**

**    DISABLE(?MoveUp)**

**    DISABLE(?MoveDown)**

**   END**

**   MSWindow.Run()**

**   CLOSE(MultiWindow)**

**   DISPLAY(SELF.Feq)**

**   IF MSWindow.Response=RequestCompleted THEN**

**    IF SELF.Delimiter**

**     SELF.SerializeValue()**

**    END**

**    SELF.TakeCompletedInit(RECORDS(SELF.Selected))**

**     LOOP MSSelectedIndex=1 TO RECORDS(SELF.Selected)**

**      GET(SELF.Selected,MSSelectedIndex)**

**      SELF.TakeCompletedProcess(MSSelectedIndex,SELF.Selected.Item,SELF.Selected.Mark)**

**      SELF.Available.Item=SELF.Selected.Item**

**      SELF.Available.Mark=0**

**      ADD(SELF.Available)**

**     END**

**     FREE(SELF.Selected)**

**     SORT(SELF.Available,SELF.Available.Item)**

**   END**

**   RETURN CHOOSE(MSWindow.Response=RequestCompleted, EditAction:Ignore, EditAction:None)**

**  ELSE**

**    RETURN PARENT.TakeEvent(E)**

**  END**
