Integrate Reporting Services by using ReportViewer controls - data collection
The control collects anonymous usage data to better understand how customers make use of the product. Usage data enables future development to be focused on improvements that are most relevant to customers.
An explanation of the data collection and usage practices of Microsoft SQL Server and Report Viewer are available in the privacy statement.
Opting out of data collection
Collection of usage data can be disabled through the EnableTelemetry property.
<rsweb:ReportViewer ID="ReportViewer1" runat="server" EnableTelemetry="false">
</rsweb:ReportViewer>
Or pragmatically before the control is rendered.
protected void Page_Load(object sender, EventArgs e)
{
ReportViewer1.EnableTelemetry = false;
}
