Applies To
Chart control, Combo Box control, List Box control, Table field, Unbound Object Frame control.
Description
You can use the ColumnHeads property to display a single row of column headings for list boxes, combo boxes, and OLE objects that accept column headings. You can also use this property to create a label for each entry in a chart control. What is actually displayed as the first-row column heading depends on the object's RowSourceType property setting.
Setting
The ColumnHeads property uses the following settings.
Setting
Description
Visual Basic
Yes
Column headings are enabled and either field captions, field names, or the first row of data items are used as column headings or chart labels.
True (–1)
No
(Default) Column headings are not enabled.
False (0)
You can set the ColumnHeads property by using the control's property sheet, a macro, or Visual Basic.
For table fields, you can set this property on the Lookup tab of the Field Properties section of table Design view for fields with the DisplayControl property set to Combo Box or List Box.
Tip Microsoft Access sets the ColumnHeads property automatically when you select Lookup Wizard as the data type for a field in table Design view.
Remarks
The RowSourceType property specifies whether field names or the first row of data items are used to create column headings. If the RowSourceType property is set to Table/Query, the field names are used as column headings. If the field has a caption, then the caption is displayed. For example, if a list box has three columns (the ColumnCount property is set to 3) and the RowSourceType property is set to Table/Query, the first three field names (or captions) are used as headings.
If the RowSourceType property is set to Value List, the first row of data items entered in the value list (as the setting of the RowSource property) will be column headings. For example, if a list box has three columns and the RowSourceType property is set to Value List, the first three items in the RowSource property setting are used as column headings.
Tip If you can't select the first row of a list box or combo box in Form view, check to see if the ColumnHeads property is set to Yes.
Headings in combo boxes appear only when displaying the list in the control.
