Hi,

I tried to replicate the issue that you are facing at my end under the version 2012, 3, 1016, 35 . But no avail. Following is the sample code that worked as expected at my end.

ASPX:

<telerik:RadTextBox ID="RadTextBox1" runat="server" AutoPostBack="true" OnTextChanged="RadTextBox1_TextChanged">
</telerik:RadTextBox>
<telerik:RadNotification ID="RadNotification1" runat="server" Text="RadNotification">
</telerik:RadNotification>

C#:

protected void RadTextBox1_TextChanged(object sender, EventArgs e)
{
    RadNotification1.Show();
}

Please provide your entire code where I can replicate the issue if it doesn't helps.

into vb net i wrote this code:

Protected Sub Txtpwdnewconf_TextChanged(sender As Object, e As System.EventArgs) Handles Txtpwdnewconf.TextChanged
    If Txtpwdnew.Text <> Txtpwdnewconf.Text Then
        Me.RadNotification1.Show("Conferma password non errata.")
    End If
End Sub

but nothing the problem there's...the values of the radtextbox (txtpwdnew and txtpwnconf) are reset after load event  Txtpwdnewconf_TextChanged

Hi,

Since it is a password field it is the expected behavior for security reasons.All the other fields are saved in ViewState and repopulated on postback, but not password fields. One suggestion to retain the value is that you can show the RadNotification using the OnValueChanged client event as follows.

ASPX:

<telerik:RadTextBox ID="Txtpwdnew" runat="server" TextMode="Password">
</telerik:RadTextBox>
<telerik:RadTextBox ID="Txtpwdnewconf" runat="server" TextMode="Password" ClientEvents-OnValueChanged="OnValueChanged">
</telerik:RadTextBox>
<telerik:RadNotification ID="RadNotification1" runat="server" Text="RadNotification">
</telerik:RadNotification>

JS:

<script type="text/javascript">
    function OnValueChanged(sender, args) {
        var Txtpwdnewconf = sender;
        var Txtpwdnew = $find("<%= Txtpwdnew.ClientID %>");
         var notification = $find("<%= RadNotification1.ClientID %>");
         if (Txtpwdnew.get_value() != Txtpwdnewconf.get_value()) {
             notification.show();
         }
    }
</script>

Hope this helps.
