This article was previously published under Q84056 SUMMARY
If you assign a value to the Text property of a combo box with Style=2
(Dropdown list), you will receive a
'Text' property is read-only
error message. To assign a default value to a combo box with the Style
property set to 2, you need to set the ListIndex property of the combo
box. If you assign a value to the Text property of a combo box with
Style set to 0 (Dropdown Combo) or 1 (Simple Combo), you will not get
the above error message.
MORE INFORMATION
A combo box combines the features of a text box and a list box. The
user can make a selection by selecting an item from its list or by
entering text in the text box portion of the combo box at the top of
the combo box.
If the Style property is set to 0 (Dropdown Combo) or 1 (Simple
Combo), the user can select an item in the list or enter text in the
text portion of the combo box. The text entered may or may not be an
item in the list. A default value for the combo box can be set either
by assigning a value to the ListIndex property or by assigning a value
to the Text property of the combo box.
However, if the Style property is set to 2 (Dropdown List), the user
can only select an item from the list. The user cannot enter text
directly in the text portion of the combo box. Therefore, a default
item for the combo box can be set by assigning a value to the
ListIndex property. The Text property of a combo box with Style set to
2 (Dropdown List) is read-only.
