SSRS 2014 - IE 11 - Toolbar items may render in multiple rows instead of one row.

I have been facing issues with SSRS 2008 R2, The reports were freezing and not showing any data. Microsoft did not provide any support as SQL 2008 R2. MS anyways closed for any new enhancements SQL 2008 variants.

We upgraded to SSRS 2014, reports started working and data was rendered. Wait, now the toolbar started appearing in multiple rows. For smaller resolution screens, this was not acceptable. I could not find any solution or fix by Microsoft for SSRS 2014, though I could find a workaround that worked for me.

This workaround requires me to modify the ReportViewer.aspx file.

The ReportViewer.aspx file is located under Pages Folder at %ProgramFiles%\Microsoft SQL Server\MSRS12.MSSQLSERVER\Reporting Services\ReportServer\Pages. 

The folder name and path may differ based on the SQL Version and installation location, the path provided above is generalized.

1. Take backup of original ReportViewer.aspx file, just in case the changes have to be restored.
2. Open ReportViewer.aspx, 
• find meta Tag
  
• Replace the content property with content="IE=EmulateIE10; IE=Edge" in the tag
3. Restart the SSRS service
4. Try the report now, it should work
5. It it does not work, then try different options in the content, example: IE=EmulateIE7 etc.

Changing this option will try to Emulate the Report with version specified in order.

Setting up Anonymous Access for Reporting Services in SQL Server 2008 R2.

DISCLAIMER: ANONYMOUS ACCESS IS NOT RECOMMENDED as it may give direct access to your report server or report objects to any one who knows the URL of your reporting services. Additional security measurements are required while handling with anonymous access.
Microsoft has made some fundamental modifications with SQL Server 2008 Reporting Services security architecture. Reporting Services and Web Component now do not need IIS or Web Server as Reporting Services now run on it's own http.sys and serves the reports request from within http.sys.
The biggest challenge I faced while configuring Reporting Services was Anonymous Access as Anonymous Access is no more an option available to be configured easily. To enable Anonymous Access you need to configure config files and also compile dll to provide extension to Reporting Services to allow Anonymous access.
Here are the steps which can be performed to enable Anonymous Access in Reporting Services.

• Change the authentication mode in rsreportserver.config to Custom

<Authentication>

<AuthenticationTypes>

<Custom/>

</AuthenticationTypes>

<EnableAuthPersistence>true</EnableAuthPersistence>

</Authentication>

• Change the Authentication mode in web.config file in ReportServer to None. Also change the Impersonation to false.

<authentication mode="None" />
<identity impersonate="false"/>

• Compile the code from this location to bin folder as Microsoft.Samples.ReportingServices.AnonymousSecurity.dll Or copy it from this location and paste it to bin folder in ReportServer.
• Add Extensions in rsreportserver.config
• Add the additional extension in Security Tag

<Security>
<Extension Name="None" Type="Microsoft.Samples.ReportingServices.AnonymousSecurity.Authorization, Microsoft.Samples.ReportingServices.AnonymousSecurity" />
</Security>

• Add the additional extension in Authentication Tag

<Authentication>
<Extension Name="None" Type="Microsoft.Samples.ReportingServices.AnonymousSecurity.AuthenticationExtension, Microsoft.Samples.ReportingServices.AnonymousSecurity" />
</Authentication>

• Add the following codegroup to configure the code access security in rssrvpolicy.config

<CodeGroup
class="UnionCodeGroup"
version="1"
PermissionSetName="FullTrust"
Name="Private_assembly"
Description="This code group grants custom code full trust. ">
<IMembershipCondition
class="UrlMembershipCondition"
version="1"
Url="C:\Program Files\Microsoft SQL Server\MSRS10.MSSQLSERVER\Reporting Services\ReportServer\bin\Microsoft.Samples.ReportingServices.AnonymousSecurity.dll"
/>
</CodeGroup>

Restart the reporting services, Anonymous Access should work.
