}

if (extension.Name == “EXCEL”) // change “Excel” name on the list to “Excel 97-2003 Workbook”
{
info = extension.GetType().GetField(“m_localizedName”, BindingFlags.Instance | BindingFlags.NonPublic);
if (info != null) info.SetValue(extension, “Excel 97-2003 Workbook”);
}
}
}

Hope this helps!

foreach (RenderingExtension extension in ReportViewer1.ServerReport.ListRenderingExtensions())
{
if (extension.Name == “XML”)
{
FieldInfo info = extension.GetType().GetField(“m_isVisible”, BindingFlags.NonPublic | BindingFlags.Instance);
if (info != null)
{
info.SetValue(extension, false);
}
}

}

I worked with a version 9.0.0.0 and I found a lot of problems. I solved these problems with the code below:
public void DisableUnwantedExportFormats()
{
foreach (RenderingExtension extension in serverReport.ListRenderingExtensions())
{
if (extension.Name == “XML” || extension.Name == “IMAGE” || extension.Name == “MHTML”)
{
ReflectivelySetVisibilityFalse(extension);
}
}
}

private void ReflectivelySetVisibilityFalse(RenderingExtension extension)
{
FieldInfo info = extension.GetType().GetField(“m_isVisible”,
BindingFlags.NonPublic | BindingFlags.Instance);

if (info != null)
{
info.SetValue(extension, false);
}
}

// regards.

Thanks it worked like magic. I was using version 8.0.0.0 of report viewr common and webforms and it worked.

To be honest I do not fully understand the solution but it works.

Thanks again.

Unfortunately this technique only works with Reporting Services 2005, I haven’t updated it for 2008. If you wish to disable Excel export you can still do this across the entire Reporting Services server, but this will disable Excel for all reports on the server, not just a specific report.

You will need to modify the Render section in your Reporting Services configuration file. MSDN has more information here: http://msdn.microsoft.com/en-us/library/ms156281.aspx
