Formview DataRowView

Hello experts,

I am needing to a record from my DataRowView to make some calculations and then bind the result to a label control.
How do I achieve this if the control being used is a formview control.

In a datalist control, I do the following;-
 string DOORPLAN = ((DataRowView)e.Item.DataItem)["DOORPLAN"].ToString();

in the ItemDataBound event of the control

protected void DataList1_ItemDataBound(object sender, DataListItemEventArgs e)
    {
             string DOORPLAN = ((DataRowView)e.Item.DataItem)["DOORPLAN"].ToString();
             ///do stuff then bind result to control
    }


What is the equivalent for formviews
