You can achieve this using data keys on the GridView, like this:

<asp:GridView ID="GridView1" runat="server" DataKeyNames="SomeID, SomeOtherColumn" OnRowDataBound="GridView1_RowDataBound" ...>

And in the code-behind:

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    int someID = (int)GridView1.DataKeys[e.Row.RowIndex]["SomeOtherColumn"];

    //do whatever you need to do with the value
}

EDIT: Here’s an example of how you can access a data key in the RowUpdating event:

protected void TaskGridView_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
    var someValue = GridView1.DataKeys[e.RowIndex]["SomeOtherColumn"].ToString();
}

You can also access the value through the DataItem property in the RowDataBound event:

int someID = (int)DataBinder.Eval(e.Row.DataItem, "SomeID");
