A couple of practical options that avoid showing a column while keeping the value available:

  • Use GridView.DataKeyNames to store per-row values (IDs, tokens, small non-sensitive fields). Note: DataKeys are persisted in ViewState by default and therefore travel to the browser as part of the page; they are not rendered as a visible column, but they are not purely server-side. For truly confidential data, keep only the row key in DataKeys and re-query the database or fetch the secret from a server-side store on postback.
  • Put a HiddenField inside a TemplateField when the value can safely be round-tripped to the client; it will render as an <input type="hidden"> and post back the value. As suggested, client-side hiding with CSS (visibility:hidden or display:none) also keeps the data in the rendered HTML but simply hides it from view.

Example (store keys in the GridView and read them in the selected-row handler):

<asp:GridView ID="GridView1" runat="server" DataKeyNames="Id,SecretValue" OnSelectedIndexChanged="GridView1_SelectedIndexChanged">
  <Columns>
    <asp:BoundField DataField="Name" HeaderText="Name" />
    <asp:ButtonField ButtonType="Button" Text="Select" CommandName="Select" />
  </Columns>
</asp:GridView>
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
    var keys = GridView1.DataKeys[GridView1.SelectedIndex];
    var id = keys.Values["Id"];
    var secret = keys.Values["SecretValue"]; // available even though not shown as a column
}

Notes and troubleshooting: set DataKeyNames before calling DataBind (or in markup), and DataKeys are only available after binding. If you need absolute secrecy, do not send the secret to the client — store only an Id in DataKeys and fetch the sensitive value server-side. See the GridView.DataKeys docs and the HiddenField control docs for details: GridView.DataKeys/DataKeyNames and HiddenField control.

Try setting a css class to that column and setting the css style "visibility:hidden;". This way asp can still access the data but the user won't see it.

If the data is confidential then your best bet is to pull the data from DB on post back and work with it there.
