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.
