I am unable to see report viewer control in UI post button click and also in aspx I am getting the below error message in design view.

In web.config file I have added the below lines under system.webServer tag
<handlers>
<add name="ReportViewerWebControlHandler" preCondition="integratedMode" verb="*" path="Reserved.ReportViewerWebControl.axd" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
</handlers>
I don't have access to the URL (http://Modile/Reports) I am using here and not sure if that is the issue. Can anyone help me this one?

I found the solution and the issue was with the report viewer version 10 which I was using. I also gave a try with report viewer 12 and it still didn't work. But reportviewer version 11 worked perfectly and we can get them in the below link.

We need to add this assembly tag in web config file.
<assemblies>
<add assembly="Microsoft.ReportViewer.WebForms, Version=11.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" />
<add assembly="Microsoft.ReportViewer.Common, Version=11.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" />
<add assembly="Microsoft.Build.Framework, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A" />
<add assembly="System.Management, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A" />
</assemblies>
Register Assembly in aspx page will look like this once we drag and drop the report viewer control.
<%@ Register Assembly="Microsoft.ReportViewer.WebForms, Version=11.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" Namespace="Microsoft.Reporting.WebForms" TagPrefix="rsweb" %>
If your visual studio version is 4.6 then add reference for Microsoft.ReportViewer.WebForms 12.0.0.0 and Microsoft.ReportViewer.WinForms 12.0.0.0 from Reference, and change Register Assembly version to 12.0.0.0.
In the aspx page, it will look like this:
<%@ Register Assembly="Microsoft.ReportViewer.WebForms, Version=12.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" Namespace="Microsoft.Reporting.WebForms" TagPrefix="rsweb" %>
In web.config:
<system.web>
<httpHandlers>
<add path="Reserved.ReportViewerWebControl.axd" verb="*" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=12.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91"
validate="false" />
</httpHandlers>
<assemblies>
