DataGridTextBoxColumn : Thanks Dmitrity Lapshin for suggestions

Thanks Dmitrity Lapshin

First, I tried implementing by overriding IsInputKey. But,
finally realized that it works on a plain TextBox and not
within a TextBox with a DataGrid.

Dmitrity, the approach you susggested works.

I have 2 more questions though.

The ProcessKeyPreview event is fired each time I press
enter key on any columns in the Datagrid.
Is it possible to trigger the event only on a specific
column of the datagrid.

I implemented ProcessKeyPreview, and it seems to be
capturing only 'Enter' key.
Tab, and directional keys are not being captured. I have
also
implemented KeyPress and KeyDown methods to capture text
being edited. Implementing ProcessDialogKey does not seem
to make any difference other than being called before
invoking KeyPress and KeyDown methods.

Any suggestions on how to capture Tabs, and up, down, left
and right arrows.

Thanks for your suggestions.
