How to: Change the Column Widths of a Multi-Column List Box

The following example uses the ColumnWidths property to change the column widths of a multicolumn ListBox. The example uses three TextBox controls to specify the individual column widths and uses the Click event to specify the units of measure of each TextBox.

To use this example, copy this sample code to the Script Editor of a form. To run the code you need to open the form so the Open event will activate. Make sure that the form contains:

  • A ListBox named ListBox1.

  • Three custom text fields named Text1, Text2, and Text3.

  • Three TextBox controls named TextBox1, TextBox2, and TextBox3 that are bound to the custom text fields above.

  • A CommandButton named CommandButton1.

Try entering the value 0 to hide a column.

Dim MyArray(2, 3) 
Dim ListBox1 
Dim TextBox1 
Dim TextBox2 
Dim TextBox3 
Dim CommandButton1 
 
Sub Item_Open() 
Dim i, j, Rows 
 
Set ListBox1 = Item.GetInspector.ModifiedFormPages("P.2").ListBox1 
Set TextBox1 = Item.GetInspector.ModifiedFormPages("P.2").TextBox1 
Set TextBox2 = Item.GetInspector.ModifiedFormPages("P.2").TextBox2 
Set TextBox3 = Item.GetInspector.ModifiedFormPages("P.2").TextBox3 
Set CommandButton1 = Item.GetInspector.ModifiedFormPages("P.2").CommandButton1 
 
ListBox1.ColumnCount = 3 
Rows = 2 
 
For j = 0 To ListBox1.ColumnCount - 1 
 For i = 0 To Rows - 1 
 MyArray(i, j) = "Row " &; i &; ", Column " &; j 
 Next 
Next 
 
ListBox1.List() = MyArray 'Load MyArray into ListBox1 
 
TextBox1.Text = "1 in" '1-inch columns initially 
TextBox2.Text = "1 in" 
TextBox3.Text = "1 in" 
 
End Sub 
 
Sub CommandButton1_Click() 
 'ColumnWidths requires a value for each column separated by semicolons 
 ListBox1.ColumnWidths = TextBox1.Text &; ";" &; TextBox2.Text &; ";" &; TextBox3.Text 
End Sub 
 
Sub Item_CustomPropertyChange(ByVal Name) 
msgbox Name 
Select Case Name 
Case "Text1" 
 'ColumnWidths accepts points (no units), inches or centimeters; make inches the default 
 If Not (InStr(TextBox1.Text, "in") > 0 Or InStr(TextBox1.Text, "cm") > 0) Then 
 TextBox1.Text = TextBox1.Text &; " in" 
 End If 
Case "Text2" 
 'ColumnWidths accepts points (no units), inches or centimeters; make inches the default 
 If Not (InStr(TextBox2.Text, "in") > 0 Or InStr(TextBox2.Text, "cm") > 0) Then 
 TextBox2.Text = TextBox2.Text &; " in" 
 End If 
Case "Text3" 
 'ColumnWidths accepts points (no units), inches or centimeters; make inches the default 
 If Not (InStr(TextBox3.Text, "in") > 0 Or InStr(TextBox3.Text, "cm") > 0) Then 
 TextBox3.Text = TextBox3.Text &; " in" 
 End If 
End Select 
End Sub
