The best way includes 3 steps. 1. Assign DataKeyName in Grid definition. 2. Set Visible to false in column definition - that will prevent sending values to the browser. 3. Use SelectedIndexChanging event of Grid view. As this event is fired long begore PageUnload the data in column still accessible. You can store that value in ViewState, Session or just pass it to another method.

protected void GridView1_SelectedIndexChanging(object sender, GridViewSelectEventArgs e)
    {
        if (e.NewSelectedIndex != -1)
        {
            ViewState.Add("myKeyValue", GridView1.DataKeys[e.NewSelectedIndex].Value);

        }
