Textbox & DataEnvironment Command

In a Data Environment, I designed a command, then I added a form, and in the form, I added some textbox, and let the datasource, datamember set. At first time of frmMyForm.Show vbModal, it shows the data in the database table correctly. However, after I unload the form, and do a frmMyForm.Show vbModal a second time, the data can't be shown in the textbox's correctly.

What's wrong ??? But I tested the RecordSet object can be manipulated as normal.

I have a similar problem.
I've notice that when rebindning the control (using run-time code), and then refreshing, it works.
Maybe for you it will work fine, but I have ~20 controls and I cannot rebind all controls, one by one.

If you found a better solution, please let me know.
