John,

You must have some code somewhere in your form or class hierarchy affecting things.

The form below works just as it should. If I type A the value in the first textbox chances to A1, press the tab key and the textbox value still shows A1 and focus ends up in the second textbox and the first row of the grid shows A1.

>But the problem is, what I key in is not visible in my textbox either.
>Ex.
>1. At this moment, my textbox display "ABC".
>2. I setfocus to textboxA, and key in character "Z". Textbox still show value "ABC" but cursor has move one position to right.
>3. I setfocus to other control. TextBox still show "ABC".
>4. I click/setfocus to grid, now only textboxdisplay "ZABC".
