The information in this article applies to:

  • Microsoft Visual FoxPro for Windows 5.0

This article was previously published under Q177145

SYMPTOMS

When you switch between controls in a grid's column at run-time the following error message appears:
Expression is invalid, use a valid expression for
DynamicCurrentControl.

RESOLUTION

When you set or change the DynamicCurrentControl property of a grid's Column, use '"combo1"' (an additional pair of quotes around the control string) instead of "combo1." Here's an example: 
   ThisForm.Grid1.Column1.DynamicCurrentControl = '"combo1"'

STATUS

This behavior is by design.

MORE INFORMATION

Steps to Reproduce Behavior

  1. Create a database, named Data1, and add a new table, Table1, with two fields. The first field will be ID(C10) and the second field will be Name(C20). Next, insert some records into the table.
  2. Create a new form and include Table1 in its DataEnvironment. Drag the table onto the form to create a grid control based on the table.
  3. Add a combo box control in Grid.Column1.
  4. Add a command button to the form, and type the following code in the Click event: 
          ThisForm.Grid1.Column1.DynamicCurrentControl = "combo1"
      ThisForm.Refresh
  5. Run the form and click the command button to produce the error: 
          Expression is invalid, use a valid expression for
      DynamicCurrentControl.
    NOTE: Using views causes the same error.
