[Solved] RadWindow doesn't work with GZIP compression.

[Grzesiek]

Hello!

I don't know what's going on, because when I initiate RadWindow control, it has been working some time.

Suddendly the window won't show up. I turn off compression and it shown up.

The most interesting is that, when I turn on the compression it worked again some time and die.

In global.asax I have the following code:

 Dim app As HttpApplication = TryCast(sender, HttpApplication)
            Dim acceptEncoding As String = app.Request.Headers("Accept-Encoding")
            Dim prevUncompressedStream As Stream = app.Response.Filter

            If Not (TypeOf app.Context.CurrentHandler Is Page) OrElse app.Request("HTTP_X_MICROSOFTAJAX") IsNot Nothing Then
                Return
            End If

            If String.IsNullOrEmpty(acceptEncoding) OrElse acceptEncoding.Length = 0 Then
                Return
            End If

            acceptEncoding = acceptEncoding.ToLower()

            If acceptEncoding.Contains("deflate") OrElse acceptEncoding = "*" Then
                ' defalte
                app.Response.Filter = New DeflateStream(prevUncompressedStream, CompressionMode.Compress)
                app.Response.AppendHeader("Content-Encoding", "deflate")
            ElseIf acceptEncoding.Contains("gzip") Then
                ' gzip
                app.Response.Filter = New GZipStream(prevUncompressedStream, CompressionMode.Compress)
                app.Response.AppendHeader("Content-Encoding", "gzip")
            End If

Anyone can help me?

I searched here through all forums and I found similar problem:

I think that excluding the Telerik.Web.UI.WebResource.axd from the custom compression can help me, but how do this?


If this won't work (excluding) I will send simple project.

I've found the problem.

I have a comment in my javascript function that open RadWindow after click the image:

<script type="text/javascript">
    function ShowPow() {
        //Comment here
        window.radopen(null, "RW1");
    }
</script>

With FireBug helper I recognize that after white space removing (which I also have) I have:

<script type="text/javascript">    function ShowPow() {//Comment here window.radopen(null, "RW1");   }</script>

Delete comment help and now everything works fine :-)

<script type="text/javascript">    function ShowPow() { window.radopen(null, "RW1");   }</script>
