All XUI dialog boxes support dlgitem_set(), dlgitem_get(), and all variations of dlgitem_set_xxx() and dlgitem_get_xxx() ACL functions. The id attribute of the element in the XUI document is the dialog box control name. If a control has no id specified, the control has no dialog box control name and cannot be used with dlgitem_set().

For example, if the XUI document contains the following checkbox element:

you can use dlgitem_set(win, 'full', 'VALUE', 1) to mark the check box as checked.

When using any of the dlgitem_set_xxx() functions, the value displayed in the dialog box control will be updated on-screen. However, the underlying XUI document will not change. That is, the value in the XUI document will not be updated by the dlgitem_set_xxx() function.
