I am trying to update a textbox which is on default.aspx from code within a class. The code is as follows:

            Dim m_control As Control
            Dim NewTextbox As TextBox
            NewTextbox = m_Page.FindControl("txtID")
            NewTextbox.Text = sValID

When I debug this, it seems to work but the textbox shown on the page is not updated and I am unable to see the value from another page using the following:

sString = CType(PreviousPage.FindControl("txtID"), TextBox).Text

Can someone please tell me what I'm doing wrong.

Thanks,

John
