handlers for that.

the dynamic textbox called "we1"
when i write
Private Sub we1_TextChanged (ByVal sender As System.Object, ByVal e As
System.EventArg s) Handles we1.TextChanged

End Sub

it gives me error "Handles clause requires a WithEvents variable."

Any idea?

Hi,

Declare your variable using:

WithEvents we1 as System.Web.UI.W ebControls.Text Box

Hi Mariame,

Are you adding your own handler? Here's some code to show how it is done.
Note that getting the TextChanged event to fire can be tricky... you may
need to hit the Enter key in the texbox after changing the text.

Private Sub Page_Load _
(ByVal sender As System.Object, _
ByVal e As System.EventArg s) Handles MyBase.Load
Dim txtbx As New TextBox
txtbx.ID = "Mytextbox"
txtbx.Text = "Change this text and hit Enter"
txtbx.EnableVie wState = True
PlaceHolder1.Co ntrols.Add(txtb x)
AddHandler txtbx.TextChang ed, AddressOf TextBox_TextCha nged
End Sub

Private Sub TextBox_TextCha nged _
(ByVal sender As System.Object, ByVal e As System.EventArg s)
Dim txtbx As TextBox
txtbx = sender
Label1.Text = txtbx.ID & " at " & Now.ToLongTimeS tring
End Sub

<form id="Form1" method="post" runat="server">
<p>
<asp:placeholde r id="PlaceHolder 1"
runat="server"> </asp:placeholder >
<asp:label id="Label1" runat="server"> </asp:label></p>
<p>&nbsp;</p>
</form>

Does this help?
