SYMPTOMS
Using the ADDITEM method to add elements to an outline control produces no output. When the form containing the OLE object is run, only the first element of the list is displayed. No other items are visible on the list. Clicking the first element has no effect.



CAUSE
The items are added to the list, but are not visible. Their indentation level is set to 0.



RESOLUTION
Use the INDENT property of the outline control to set the indentation level for the specified item.



STATUS
This behavior is by design.



MORE INFORMATION
There are two ways to use the ADDITEM method, with and without an optional numeric parameter. Here is what happens in each case:   You do not include an optional numeric parameter with the ADDITEM method, for example: FrmForm1.Outl1.Additem('TextBox') This line of code adds the item labeled TextBox. The item is added to end of the list or as a subordinate item, depending on whether or not an element in the list is selected when the item is added.   You do include an optional parameter with the ADDITEM method to indicate the relative position of an element in the list. If an item already exists at this position, the indentation level remains the same, for example: FrmForm1.Outl1.Additem('Command',1) Frm1.Outl1.Indent(1)=1 Frm1.Outl1.Additem('CheckBox',1) If the new item uses a new index when it is added (that is, no element existed at this position), the indentation level of the new item is 0. Because only the first element of the list is visible at indent 0, the indentation level of other items will need to be modified. 

For more information about the Outline control and the Properties, Events, and Methods associated with it, search for Outline using the Visual FoxPro Help menu.

Steps to Reproduce Behavior
The following steps demonstrate how to use the INDENT property to display items:  Create a form. Select the OLE Container from the Form Controls toolbox, and place the OLE container object on the form.</li> The Insert Object dialog is displayed. Select the Insert Control option button and the Outline Control from the list. Click OK, and the control is placed on the form.</li>  In the Properties Sheet, select the OleControl1 object, and open the Init event handler for this object. Place the following code in the Init: * The following lines add items to the list This.Additem('Vegetables',0) && This.Additem('Carrots',1) This.Additem('Potatoes',2) This.Additem('Fruit',3) This.Additem('Apples',4) This.Additem('Oranges',5)

** The following lines set the indentation level of the elements. ** Without this code, the items would not be visible.

This.Indent(0)=1 This.Indent(1)=2 This.Indent(2)=2 This.Indent(3)=1 This.Indent(4)=2 This.Indent(5)=2 </li> Save the form, and run it.</li></ol>
