There is no way to turn them off per report with the built in UI. &nbsp;You can mark them as hidden in the report server config file or remove particular rendering extensions entirely, but these are both site wide settings. <br />
<br />
I know you're using the ReportViewer control, you can hide the built-in export drop down and implement your own that lists only the extensions you want by calling Render on the ServerReport object directly.<br />
example:<br />
<a href="http://MYSERVER/ReportServer?MyReport&rs:Command=Render&rs:Format=WORD" rel="ugc">http://MYSERVER/ReportServer?MyReport&rs:Command=Render&rs:Format=WORD</a>&nbsp;<br />

Hi experts, i'm using the report viewer of reporting services with the option ReportViewer1.ShowExportControls = true; 
My question is whether it is possible to show the microsoft word as single format of export?

ReportViewer1.ShowExportControls = true;

SQL Server Reporting Services (SSRS) is a server-based report generation software system from Microsoft. It can prepare and deliver a variety of interactive and printed reports and is administered via a web interface or its web service. Its web services interface also supports the development of custom reporting applications. Finally, SSRS can also be integrated with SharePoint. SSRS competes with other business intelligence tools, most prominently Crystal Reports.
