datagridcolumnstyle with 2 or more text box

Hi, does anyone have ever done this. a datagridcolumnstyle which contain more then one textbox. i create a datagridcolumnstyle with 5 textbox. the edit and display works fine, but the textbox cannot receive the 'arrow keystroke', when ever the arrow keystroke is pressed, the datagrid catch the event and move the focus to the next cell. can anyonw help.

i try another way, by using datagridtextbox. but it turn out i can't press any alpha numeric keystroke since it will go wrong and give error message " reference to nothing .. something like that"

i could send the code. but it's quite big to cut and paste here. so i will send to email with request.
