PRB: Error Changing DynamicCurrentControl of Grid Column

ID: Q177145

The information in this article applies to:

Microsoft Visual FoxPro for Windows, versions 5.0, 5.0a

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.
