Radchart save problem

[Kishor]

hello 

I want to export RadChart to excel so first Iam saving it.

following is my code

 Protected Sub btnSaveChart_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSaveChart.Click
        Try

            Dim ms As New System.IO.MemoryStream
            RadChart1.Save(ms, System.Drawing.Imaging.ImageFormat.Png)
            Page.Response.Clear()
            Page.Response.ClearHeaders()
            ' Page.Response.AddHeader("Content-disposition", "attachment; filename=Chart.png")
            Page.Response.AddHeader("Content-type", "image/png")
            Page.Response.BinaryWrite(ms.ToArray())
            Page.Response.End()

        Catch ex As Exception

        End Try
       
    End Sub

But it does not work  , it gives following error

  Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.

Hello,

Could you please send us a small runnable copy of your project reproducing the issue so we could debug it locally. You can open up a support ticket and attach the sample there.

You could also take a look at the Code Library here as it might help you in figuring out what is causing the issue.
