Automatically refreshing your SQL Reporting Services reports with the AutoRefresh element
If want your report to auto refresh every x seconds inside IE, take a look at the AutoRefresh RDL element: <AutoRefresh> is a child of <Report> and a peer or the <Body> element in your document. For example, if you want your report to autorefresh every 15 seconds, you'd add the AutoRefresh element to the RDL in your report like so:
<Report>
<AutoRefresh>15</AutoRefresh>
<Body>
...
</Body>
</Report>
