Hi, I’m currently experiencing a problem with the RadDataPager and the Dialog handlers.

My application has a RadListView control with a RadDataPager in the layout. In the RadDataPager, I’m using the Routing functionality. In the Application_Start I have the relevant registration as documented in the forums here.

The problem is, when I register routes it breaks the handlers for the Telerik Dialogs in the RadEditor and other such controls. I will post the code that I think is the source of the problem and where the problem arises.

the aspx file has this section:
<Telerik:RadListView ID="RadListView1" runat="server"
        DataSourceID="SqlSource"
        ItemPlaceholderID="ItemContainer"
        AllowPaging="True"
        InsertItemPosition="FirstItem"
        ClientIDMode="Static">
    <LayoutTemplate>
        <asp:PlaceHolder ID="ItemContainer" runat="server" />
        <Telerik:RadButton ID="InsertButton" runat="server"
                CssClass="InsertButton"
                Text="New Announcement"
                ButtonType="LinkButton"
                CommandName="InitInsert"
                Skin="CustomRad"
                EnableEmbeddedSkins="False"
                EnableAjaxSkinRendering="False"
                Visible='<%# Not Container.IsItemInserted %>'>
                    <Icon PrimaryIconCssClass="rbAdd" PrimaryIconLeft="4" PrimaryIconTop="4" />
        </Telerik:RadButton>
 
        <Telerik:RadDataPager ID="RadDataPager1" runat="server"
                PagedControlID="RadListView1"
                PageSize="5"
                AllowSEOPaging="true"
                SEOPagingQueryPageKey="Page"
                    AllowRouting="true"
                    RouteName="AnouMain"
                    RoutePageIndexParameterName="Page">
            <Fields>
                <Telerik:RadDataPagerButtonField FieldType="FirstPrev" />
                <Telerik:RadDataPagerButtonField FieldType="Numeric"
                        FirstButtonText="First"
                        LastButtonText="Last"
                        NextButtonText="Next"
                        PrevButtonText="Prev" />
                <Telerik:RadDataPagerButtonField FieldType="NextLast" />
            </Fields>
        </Telerik:RadDataPager>
    </LayoutTemplate>
         ... Templates omitted ...
</Telerik:RadListView>

the class i use for the registering of routes is:

Namespace SeoRouting
 
    ''' <summary>
    ''' Route Registering and other SEO Op functions and subs
    ''' </summary>
    ''' <remarks>TODO: Remarks to follow</remarks>
    Public Class Register
 
        Public Shared Sub Routes(ByVal Routes As System.Web.Routing.RouteCollection)
            Dim RouteValueDictionary As New System.Web.Routing.RouteValueDictionary()
            RouteValueDictionary.Add("Page", "1")
            Routes.MapPageRoute("AnouDefa", "en/Anou/{Page}", "~/en/Anou/Default.aspx", True, RouteValueDictionary)
            Routes.MapPageRoute("AnouMain", "announcements/Page{Page}", "~/en/Anou/Main.aspx", True, RouteValueDictionary)
        End Sub
 
    End Class
 
End Namespace

and the app start looks like this:

Sub Application_Start(ByVal sender As Object, ByVal e As EventArgs)
        SeoRouting.Register.Routes(RouteTable.Routes)
End Sub

the web.config:

<httpHandlers>
    <!--<add verb="*" path="*.psd" type="System.Web.HttpForbiddenHandler" />-->
    <add path="ChartImage.axd"
         type="Telerik.Web.UI.ChartHttpHandler"
         verb="*" validate="false" />
    <add path="Telerik.Web.UI.SpellCheckHandler.axd"
         type="Telerik.Web.UI.SpellCheckHandler"
         verb="*" validate="false" />
    <add path="Telerik.Web.UI.DialogHandler.aspx"
         type="Telerik.Web.UI.DialogHandler"
         verb="*" validate="false" />
    <add path="Telerik.RadUploadProgressHandler.ashx"
         type="Telerik.Web.UI.RadUploadProgressHandler"
         verb="*" validate="false" />
    <add path="Telerik.Web.UI.WebResource.axd"
         type="Telerik.Web.UI.WebResource"
         verb="*" validate="false" />
</httpHandlers>
    <handlers>
        <remove name="ChartImage_axd" />
        <remove name="Telerik_Web_UI_SpellCheckHandler_axd" />
        <remove name="Telerik_Web_UI_DialogHandler_aspx" />
        <remove name="Telerik_RadUploadProgressHandler_ashx" />
        <remove name="Telerik_Web_UI_WebResource_axd" />
        <add name="ChartImage_axd" path="ChartImage.axd"
             type="Telerik.Web.UI.ChartHttpHandler"
             verb="*" preCondition="integratedMode" />
        <add name="Telerik_Web_UI_SpellCheckHandler_axd"
             path="Telerik.Web.UI.SpellCheckHandler.axd"
             type="Telerik.Web.UI.SpellCheckHandler"
             verb="*" preCondition="integratedMode" />
        <add name="Telerik_Web_UI_DialogHandler_aspx"
             path="Telerik.Web.UI.DialogHandler.aspx"
             type="Telerik.Web.UI.DialogHandler"
             verb="*" preCondition="integratedMode" />
        <add name="Telerik_RadUploadProgressHandler_ashx"
             path="Telerik.RadUploadProgressHandler.ashx"
             type="Telerik.Web.UI.RadUploadProgressHandler"
             verb="*" preCondition="integratedMode" />
        <add name="Telerik_Web_UI_WebResource_axd"
             path="Telerik.Web.UI.WebResource.axd"
             type="Telerik.Web.UI.WebResource" verb="*"
             preCondition="integratedMode" />
    </handlers>
</system.webServer>

so to be clear, when i have the routing on in the App_Start the dialogs don’t function throwing an error saying that the handlers are
missing from the Web.config I reviewed This Telerik Document for help but couldn’t see the solution.


Kind Regards.
M Mason.

Hi Michael,

You can try replacing Telerik.Web.UI.DialogHandler.aspx with Telerik.Web.UI.DialogHandler.axd in the web.config file and set the RadDataPager's DialogHandlerUrl property to "~/Telerik.Web.UI.DialogHandler.axd".
