Evaluate Datalist Controls

[alex_read]

I've got this code to go through all textboxes on a webform & look to see if each of them have a blank value. How can I use something like this to go through all item textbox controls created in/by a datalist please???

For each ctlWebFormControl in page.Controls
    If (ctlWebFormControl.GetType.ToString.
    Equals("System.Web.UI.WebControls.TextBox")) then
        If not(CType(ctlWebFormControl, _
        System.Web.UI.WebControls.TextBox).Text  = "")) then_
            ' Something Here
        End if
    End If
Next

Thanks!!
