ASP.NET Gridview Editing -

The datasource for my gridview contains a column named "price". This value is an integer and represents the number of cents that the item costs. I want to display this to the user as a dollar value so I have the following:

 Protected Sub gvDetails_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gvDetails.RowDataBound
        If e.Row.RowType = DataControlRowType.DataRow Then
            Dim row As GridViewRow = e.Row()

            Dim view As DataRowView = row.DataItem
            Dim val As Integer
            'price
            Dim val As Integer = Integer.Parse(view("price"))
            row.Cells(5).Text = (val / 100).ToString("C")
     
        End If
    End Sub

This works fine to display the value to my user.

I am allowing editing in my gridview.

After I implement this formatting when I go to edit a row in the gridview the price field does not display in a textbox.

How do I keep my formatting and allow the user to edit this field inside the gridview.

Samples would be most helpful.
