ComboBox.ColumnWidths Property (Access)

You can use the ColumnWidths property to specify the width of each column in a multiple-column combo box. Read/write String.

expression .ColumnWidths

expression A variable that represents a ComboBox object.

The ColumnWidths property holds a value specifying the width of each column in inches or centimeters, depending on the measurement system (U.S. or Metric) selected in the Measurement system box on the Number tab of the Regional Options dialog box of Windows Control Panel. The default setting is 1 inch or 2.54 centimeters. The ColumnWidths property setting must be a value from 0 to 22 inches (55.87 cm) for each column in the list box or combo box.

To separate your column entries, use semicolons (;) as list separators (or the list separator selected in the List separator box on the Number tab of the Regional Options dialog box).

A width of 0 hides a column. Any or all of the ColumnWidths property settings can be blank. You create a blank setting by typing a list separator without a preceding value. Blank values result in Microsoft Access automatically setting a default column width that varies depending on the number of columns and the width of the combo box or list box.

In a combo box, the first visible column is displayed in the text box portion of the control.

In Visual Basic, use a string expression to set the column width values in twips. Column widths are separated by semicolons. To specify a different unit of measurement, include the unit of measure (cm or in). For example, the following string expression specifies three column widths in centimeters.

"6 cm;0;6 cm"

You can also use this property to hide one or more columns.

If you leave the ColumnWidths property setting blank, Microsoft Access sets the width of each column as the overall width of the list box or combo box divided by the number of columns.

If the column widths you set are too wide to be fully displayed within the combo box or list box, the rightmost columns are hidden and a horizontal scroll bar appears.

If you specify the width for some columns but leave the setting for others blank, Microsoft Access divides the remaining width by the number of columns for which you haven't specified a width. The minimum calculated column width is 1,440 twips (1 inch).

For example, the following settings are applied to a 4-inch list box with three columns.

Setting

Description

1.5 in;0;2.5 in

The first column is 1.5 inches, the second column is hidden, and the third column is 2.5 inches.

2 in;;2 in

The first column is 2 inches, the second column is 1 inch (default), and the third column is 2 inches. Because only half of the third column is visible, a horizontal scroll bar appears.

(Blank)

The three columns are the same width (1.33 inches).

Note Note

This property is different than the ColumnWidth property, which specifies the width of a specified column in a datasheet.

The following example show how to create a combo box that is bound to one column while displaying another. Setting the ColumnCount property to 2 specifies that the cboDept combo box will display the first two columns of the data source specified by the RowSource property. Setting the BoundColumn property to 1 specifies that the value stored in the first column will be returned when you inspect the value of the combo box.

The ColumnWidths property specifies the width of the two columns. By setting the width of the first column to 0in., the first column is not displayed in the combo box.

Private Sub cboDept_Enter()
    With cboDept
        .RowSource = "SELECT * FROM tblDepartments ORDER BY Department"
        .ColumnCount = 2
        .BoundColumn = 1
        .ColumnWidths = "0in.;1in."
    End With
End Sub
