Read Text Column GridViewRow Data

Hello Experts,
I am trying to read a GridView in c#.  Till Cell(3), I am able to read the data.  But, Cell[4] shows empty, which is a text field contains date.  This filed is Edit/Update field.  Any idea, why I am not able get the data?  Below is the code.

Thank you in advance!

    string Id, Name, FNumber, FName, FValue;
    foreach (GridViewRow Item in grdImportView.Rows)
    {
        PId = Item.Cells[0].Text;
        PName = Item.Cells[1].Text;
        FNumber = Item.Cells[2].Text;
        FName = Item.Cells[3].Text;
        FValue = Item.Cells[4].Text;
    }
