The following example uses the TextColumn property to identify the column of data in a ListBox that supplies data for its Text property. This example sets the third column of the ListBox as the text column. As you select an entry from the ListBox, the value from the TextColumn will be displayed in the TextBox.
This example also demonstrates how to load a multicolumn ListBox using the AddItem method and the List property.
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:
Dim ListBox1
Dim TextBox1
Sub Item_Open()
Set ListBox1 = Item.GetInspector.ModifiedFormPages.Item("P.2").Controls("ListBox1")
Set TextBox1 = Item.GetInspector.ModifiedFormPages.Item("P.2").Controls("TextBox1")
ListBox1.ColumnCount = 3
ListBox1.AddItem "Row 1, Col 1"
ListBox1.List(0, 1) = "Row 1, Col 2"
ListBox1.List(0, 2) = "Row 1, Col 3"
ListBox1.AddItem "Row 2, Col 1"
ListBox1.List(1, 1) = "Row 2, Col 2"
ListBox1.List(1, 2) = "Row 2, Col 3"
ListBox1.AddItem "Row 3, Col 1"
ListBox1.List(2, 1) = "Row 3, Col 2"
ListBox1.List(2, 2) = "Row 3, Col 3"
ListBox1.TextColumn = 3
End Sub
Sub ListBox1_Click()
TextBox1.Text = ListBox1.Text
End Sub
