GridView and CommandField

I have a GridView where 1st cell is a CommandField like:

Code:

---

<asp:CommandField HeaderText="Select" SelectText="Ticket" ShowSelectButton="True" >
  <HeaderStyle HorizontalAlign="Center" />
  <ItemStyle HorizontalAlign="Center" />
</asp:CommandField>

---

Is there a way that I can condition the display and also condion the Button click using code behind. Depending upon content of one of the other cells I would like to be able to condition whether to be able to clik or not. I assume I would do this in RowDataBound and wonder if there is properties to control this?

Thank you.
