SSRS Reports - How to Hide/Disable the atomFeed/ Datafeed icon on SSRS ReportViewer page?

I got a requirement for a dashboard in which the end user doesn't want the datafeed icon to be displayed on the Report because of the crucial data in the report. His concern was if by mistake some body click on the datafeed icon all the data will be available publicly.

As this requirement is only for one report, so the challenge was how to disable the datafeed icon for that particular report.

There is one parameter (&rc:Stylesheet) which is useful in this case.

Let’s see how it work:
to customize the toolbar for the ReportViewer
1. Open the directory at the following location of your Microsoft SQL server installation:
<drive>:\Program Files\Microsoft SQL Server\MSRS10_50.<InstanceName>\Reporting Services\ReportServer\Styles
2. Create a copy of the file “HtmlViewer.css” in the same folder and name it "CustomHtmlViewer.css".
3. Open “CustomHtmlViewer.css”, find the section

.ToolbarAtomDataFeed

{
          display: inline;
}

Change it to

.ToolbarAtomDataFeed
{
          display: none;
}

Save the file. 

4. Now in the link of the Report pass the parameter for the stylesheet:

http://<ServerName>/ReportServer/Pages/ReportViewer.aspx?%<FolderName>%2<ReportName>&rc%3aStylesheet=CustomHtmlViewer

and you will see that the datafeed icon is gone from your ReportViewer toolbar for this report.

After disabling the datafeed icon 

Few points to remember:
1. To modify the "HtmlViewer.css" file you have admin rights on that machine where the SQL server is installed.
2. Pass the newly created stylesheet name as parameter in the link.
3. Don’t add the .css extension in the stylesheet name in the link.
4. Note: we only want to disable the datafeed icon for a single report, so we are not going to modify the ReportServer.config file.
