PRB: ComboBox ReadOnly Property Applies Only to Dropdown Combo (156510)

MORE INFORMATION

The ReadOnly property has been added to the ComboBox control for Visual FoxPro 5.0. As with other controls (such as TextBox or EditBox), it applies only to the region of the control that accepts text input. The ComboBox has such a region only if the Style property is set to 0 - Dropdown Combo, so the ReadOnly property can be set only to .T. for ComboBoxes of this Style.

Steps to Reproduce Behavior

1. Type the following in the Command window to create a new form and open it in the Form Designer:

         CREATE FORM combotst
   						

2. In the Form Designer, add a ComboBox to the form.
3. In the Property window, set the Style property for the ComboBox control to "2 - Dropdown list."
4. When you try to change the ComboBox ReadOnly property, notice it cannot be changed from .F.

NOTE: If the Style property of a combo box with its ReadOnly property set to .T. is changed from 0 - Dropdown Combo to 2 - Dropdown List, the ReadOnly property changes to .F. This occurs at both design-time and run- time.
