Question

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.

If I am not mistaken, GridView does not hold the values of BoundColumns that have the attribute visible="false". Two things you may do here, one (as explained in the answer from V4Vendetta) to use Datakeys. Or you can change your BoundColumn to a TemplateField. And in the ItemTemplate, add a control like Label, make its visibility false and give your value to that Label.
