PRB: Unable to Change Sorted Property in Form Designer

ID: Q141638

3.00 3.00b WINDOWS kbprg kbprb

The information in this article applies to:

Microsoft Visual FoxPro for Windows, versions 3.0 and 3.0b

SYMPTOMS

The Sorted property of a list box or combo box contained in a form in the Form Designer cannot be changed from '.F. - False' to '.T.- True' if the RowSourceType property is set to anything other than '0 - None' or '1 - Value'.

CAUSE

The Sorted Property of a combo box or list box can be set to '.T. - True' only if the RowSourceType property is set to either '0 - None' or

'1 - Value'.

STATUS

This behavior is by design.

MORE INFORMATION

If it is intended for a list box or combo box to have a RowSourceType of anything other than 0 (None) or 1 (Value), then the Sorted Property cannot be set to anything other than '.F. - False' because it cannot have any effect on any of the other RowSourceTypes.

It is possible to set the Sorted Property to '.T. - True' while the RowSourceType is either 0 (None) or 1 (Value) and then to set the RowSourceType to something different. If this is done and a form is closed and saved, the Sorted Property will return to '.F. - False'.

For more information on the Sorted Property, please refer to the "Sorted Property" topic in the Help file.

Steps to Reproduce Behavior

NOTE: This example uses a list box, but the same could also be applied to a combo boxl.

1. Create a new form and place a list box on it.

2. Set the RowSourceType Property of the list box to '0 - None' (the

   default setting).

3. Change the Sorted property for the list box from '.F. - False' to

   '.T. - True'.

4. Change the RowSourceType property for the list box from '0 - None' to

   '5 - Array'.

5. Change the Sorted property for the list box from '.T. - True' to

   '.F. - False'. Note that attempting to change it back to '.T. - True'
   will not be allowed.

If, after implementing steps 1 through 4, you save and close the form, the list box RowSourceType property would be '5 - Array' and the Sorted property would have been '.T. - True'. But, once the form is opened within the Form Designer, the Sorted property will be reset to '.F. - False'.
