    I have an issue with the RadComboBox post back only on the Default page.

    Autopostback is enabled and my code behind works fine if my url contains the file name & extension (MySite.com/Default.aspx or /directory/Default.aspx) but not if I link only the directory (MySite.com or /directory/).

    I'm using Visual Studio 2012 and .net 4.5 (VB)

    My code is icluded in a Master Page
    <telerik:RadComboBox ID="RcbLangue" OnSelectedIndexChanged="RcbLangue_SelectedIndexChanged" AutoPostBack="True" runat="server" DataSourceID="SdsLangues" DataTextField="Name" DataValueField="LangId"></telerik:RadComboBox>
    Protected Sub RcbLangue_SelectedIndexChanged(sender As Object, e As RadComboBoxSelectedIndexChangedEventArgs)
            Session("LangId") = RcbLangue.SelectedValue
            Session("LangName") = RcbLangue.SelectedItem.Text 
    End Sub

    Is it a .net known issue, does anyone else has this problem ?

    Thanks for your support,

    Hello Herve,

    The reason for the experienced problem is indeed a know issue related to the usage of RadCompression. It's mentioned in the following help article here under the Known issues section:
    When RadCompression is enabled and you are using .NET 4.0, event handlers might not be raised in a default document in IIS 7 or IIS 7.5 Integrated Mode.

    Please try the solution suggested in the aforementioned help article.
