HOWTO: Set the Default Choice in a List Box or Combo Box

• Microsoft Visual FoxPro for Windows, versions 3.0, 5.0, 6.0

SUMMARY

When including a combo box or list box on a form, developers often want to have default selection as something other than the first item in the list. To do this, set the Value property to a value contained in the list.

MORE INFORMATION

By setting the Value property of a combo box or list box to a value contained in the list, you ensure that the item becomes selected (highlighted) as the default selection. All items contained in a combo box or list box are stored as a text variables, as such any reference to a field or variable for setting the value property must be converted to a character value. If the list contains multiple columns the Value property must contain a value in the bound column.

Step-by-Step Example

1. Using the Customer table form the Testdata Database, create a from and add a list box.



2. Set the following properties for the list box:

   
      BoundColumn = 1
      ColumnCount = 2
      ColumnWidths = 63,150
      RowSource = Customer.Cust_id,Title
      RowSourceType = 6-Fields 




3. In the Init event of the list box, add the following line of code:

   
      This.Value='FOLIG' 




4. Save and run the form, the default (highlighted) item will be the first item in the list containing "FOLIG" in the first column.
