Are you sure that the control at CartGrid.Rows[e.RowIndex].Cells[2].Controls[0] isn't a LiteralControl?  How are you creating code this in your code?

Hey Mander,

Please, do the following ...

GridViewRow gvr = GridView1.Rows[e.RowIndex];

TextBox QuantityTextBox = (TextBox)gvr.Cells[2].FindControl("TextBox1");

Please, let me know if that helped ...
