Hello Folks...
THis is very urgent ...Plz help...
Following is a piece of code....to disable all the textBoxes on a WebForm in ASP.Net.(Lang:VB.Net)


Private Sub disableAllTextBoxes(ByVal ControlArray)

Dim control As Object

Dim temptxtbox

Dim i As Integer

For Each control In ControlArray

      If control.GetType.Name = "TextBox" Then

         control.GetType.GetTypeArray(control).CopyTo(temptxtbox, 0)
         For i = 0 To UBound(temptxtbox)

         temptxtbox(i).Enabled = True

         Response.Write(temptxtbox.ID)
      Next

   End If

disableAllTextBoxes(control.Controls)
Next

End Sub

The looping is perfect.It detects the System.Web.UI.WebControls.TextBox collection.
In the above code the red colored line is the place where i get the following error....

 "System.InvalidCastException: Specified cast is not valid.

  I m a beginner ....so regret if there is something silly in it.

You can cast it this way:

temptxtbox = CType(control, TextBox)

and then do:

temptxtbox.Enabled = False
