Adding Upload Progress bar Thu. Sep 18, '08 10:59 AM (permalink)

If your hosting environment is in Full Trust mode, you can enable Upload Progress bar by making some code changes.

NOTE: if your host specifically set the trust level to Medium (most hosting companies do this), you cannot use this progress bar feature.

Click to see instruction if you see popup error message when you upload in Medium Trust

To prevent seeing the error message, you need to modify some code. There are 2 places

upload.aspx - remove or comment out (<%-- --%> )

    <telerik:RadProgressArea id="RadProgressArea1" runat="server" />         
     <telerik:RadProgressManager id="RadProgressManager1" runat="server" />

(up to version 3.2) upload.aspx.vb - comment out

        If ASPPG.Data.ApplicationDataRelated.APP_TrustLevel <> AspNetHostingPermissionLevel.Unrestricted Then        
             RadProgressArea1.Visible = False        
             RadProgressManager1.Visible = False        
         End If

Instruction to enable upload progress bar

Open upload.aspx - uncomment (removing <%-- --%> surrounding the following block)

     <telerik:RadProgressArea id="RadProgressArea1" runat="server" />         
     <telerik:RadProgressManager id="RadProgressManager1" runat="server" />

Open web.config, and make the following changes:

If you are using IIS 6 or IIS7 Classic Mode:

under system.web > httpModules, uncomment

<add name="RadUploadModule" type="Telerik.Web.UI.RadUploadHttpModule, Telerik.Web.UI" />

under system.web > httpHandlers, uncomment

<add path="Telerik.RadUploadProgressHandler.ashx" verb="*" type="Telerik.Web.UI.RadUploadProgressHandler, Telerik.Web.UI" validate="false" />

If you are using the IIS 7 Integrated Mode:

under system.webServer > modules, uncomment

<add name="ProgressModule" preCondition="integratedMode" type="Telerik.Web.UI.RadUploadHttpModule, Telerik.Web.UI" />

under system.webServer > handlers, uncomment

<add name="TelerikRadProgress" preCondition="integratedMode" path="Telerik.RadUploadProgressHandler.ashx" verb="*" type="Telerik.Web.UI.RadUploadProgressHandler, Telerik.Web.UI" />

In the SessionUpdateNotRequiredPages key under the <appSettings> section, add

~/Telerik.RadUploadProgressHandler.ashx

to the end of the file list (separated by a comma).

Application Trace must be set to false

<trace enabled="false" requestLimit="1000" pageOutput="false" localOnly="true" mostRecent="true" />

Outside of system.web, add:

    <location path="Telerik.RadUploadProgressHandler.ashx">          
         <system.web>          
             <authorization>          
                 <allow users="*"/>          
             </authorization >          
         </system.web>          
     </location>
