Hi,

How can i make theis works within AJAX Update Panel.

Response.write("<scr" + "ipt> Open(' " + filename + "') </scr? + "ipt>")

it works out side Update Panel but not inside the panel...

the error says :

 The Message recived from the server could not be parsed. Common causes for this error are the response is modifiyed ba calls to response.write(), response details , HttpModule, OR server trace is enabled.

Pls Help

Thanks

Hi.

if you want to use Page.Responce.Write in updatepanle you must register it with ScriptManager Register method.

Regards.

you can use it like this:

ScriptManager.RegisterStartupScript(Me, Me.GetType, "key", "open('" + filename + "');", True)

Thanks You, You Have Saved My Day....

Hi,

I'm getting a similar error when trying to export a gridview to an excel spreadsheet within an updatepanel.

here is the code below ;

    Protected Sub Export2Excel()

        Response.Clear()
        Response.AddHeader("content-disposition", "attachment;filename=TestExcel.xls")
        Response.Charset = ""

        'If you want the option to open the Excel file without saving than
        'comment out the line below
        Response.Cache.SetCacheability(HttpCacheability.NoCache)
        Response.ContentType = "application/vnd.xls"

        Dim stringWrite As System.IO.StringWriter = New System.IO.StringWriter()
        Dim htmlWrite As System.Web.UI.HtmlTextWriter = New HtmlTextWriter(stringWrite)

        Try
            Results_GridView.RenderControl(htmlWrite)
            Response.Write(stringWrite.ToString)
        Catch ex As Exception
        End Try

        Response.End()

    End Sub

So there are two solutions for this
1)      you can add a PostBackTrigger and give it’s ControlID as the excel export button’s ID EX:-
<Triggers>           
      <asp:PostBackTrigger ControlID=”btnExcel” />        
</Triggers>
2)      or else you can move your excel export button out side the update panel
