ObjectFrame.ColumnHeads Property (Access)
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. Read/write Boolean.
The ColumnHeads property uses the following settings.
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.
(Default) Column headings are not enabled.
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.
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.
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.
