Hello James,

You can use the MHTML rendering extension if you want to render a report in MHTML. You can find more info on the MHTML rendering extension in this help article that elaborates on its usage. You can specify rendering extension parameters in your application’s configuration file to override the default report rendering behavior.
Note that currently HTML preview would not work under Windows Vista as we are using MHTML for it. We would address this problem by switching to real HTML for the preview, as MHTML is not supported on Vista.

Sorry when i have called

Dim buffer() As Byte = ReportProcessor.Render("HTML", aContactRPT, Nothing, mime, extension, encode)

or

Dim buffer() As Byte = ReportProcessor.Render("MHTML", aContactRPT, Nothing, mime, extension, encode)

it doesn't seems to output any data, however, when i render using PDF, it's fine, any idea?

Hi James Shelton Agar,

Here is a sample code snippet which exports a report in MHTML format:

       Dim report As New Report1()

        Dim mimeType As String = String.Empty
        Dim ext As String = String.Empty
        Dim encoding As Encoding = encoding.[Default]

        Dim reportBytes As Byte() = Telerik.Reporting.Processing.ReportProcessor.Render("MHTML", report, Nothing, mimeType, ext, encoding)


        Dim fileName As String = "Report1.mhtml"

        Response.Clear()
        Response.ContentType = mimeType
        Response.Cache.SetCacheability(HttpCacheability.[Private])
        Response.Expires = -1
        Response.Buffer = False
        Response.AddHeader("Content-Disposition", String.Format("{0};FileName=""{1}""", "attachment", fileName))
        Response.OutputStream.Write(reportBytes, 0, reportBytes.Length)
        Response.End()

Give it a try and if there is still a problem please open a support ticket and send a sample project which can demonstrate it.

Kind regards,
