I have a GridView with a DataSource (SQL Database). I want to hide a column, but still be able to access the value when I select the record. Can someone show me how to do this?

This is the column I want to hide and still want to access its value:

<asp:BoundField DataField="Outlook_ID" HeaderText="OutlookID" />

I tried everything to hide the column (property Visible="false"), but I can't access its value.

ArrayList EmailList = new ArrayList();
foreach (GridViewRow itemrow in gvEmployeeDetails.Rows)
{
  EmailList.Add(itemrow.Cells[YourIndex].Text);
