Jim,

>That's the part that really has me stumped: there are no error icons. I tried creating a new form with the same controls, and now the data is read only. I can't edit any of the data! I'm almost ready to scrap the whole project and start over from scratch.

Actually, the data may not be read only...it may be that text strings in your database have trailing spaces (if you're not using varchar) and it has filled up the maximum number of characters allowed in the TextBox. By default, MM .NET automatically sets the MaxLength property on your text boxes based on the length of data in your data columns. Go to one of your text boxes and hit "End". If there are trailing spaces, remove them, then see if you can edit data. Long story short, I recommend using varchar data.

Best Regards,
