Hi All,

I am facing a problem related to response.BinaryWrite(), it is not working on telerik:RadPageView.
My code is as below.

ASPX:

<telerik:RadPageView ID="vXML" runat="server" CssClass="edit-area">

<div class="padded-container">

<asp:LinkButton runat="server" EnableViewState="false" class="padded-element-first" OnClientClick="clientButtonClicking();"

Text="Download" CommandName="XML" CausesValidation="true" ID="btnExportXML" OnCommand="btnExport_Click" />

<label id="btnImportXML" class="padded-element-last" style="cursor: pointer; color: #0E3D4F;

text-decoration: underline; display: inline" onclick='toogleDisplays("btnImportXML","divUpldXML"); return false;'>

Upload</label>

<div id="divUpldXML" style="visibility: hidden; display: inline">

<asp:FileUpload CssClass="padded-element-last" EnableViewState="false" runat="server"

ID="upldXML" />

<asp:RequiredFieldValidator ValidationGroup="grpInputs" ID="vldUpldXml" ControlToValidate="upldXML"

runat="server" ErrorMessage="PlaceholderXML is required. Enter valid PlaceholderXML."

Text="*" />

<asp:RegularExpressionValidator ValidationGroup="grpInputs" Enabled="false" ID="vldRegExpUpldXml"

runat="server" ErrorMessage=".xml extension only" ValidationExpression="^(([a-zA-Z]:)|(\\{2}\w+)\$?)(\\(\w[\w].*))(.xml|.XML)$"

ControlToValidate="upldXML" />

</div>

<tzgcontrols:XmlView Style="width: 97%; overflow: scroll; clip: auto; word-wrap: break-word;"

EnableViewState="true" ID="ViewerXML" runat="server" CssClass="XmlFormat placeholder-box" />

</telerik:RadPageView>

Javascript:

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">

<script type="text/javascript">

RadAjax.OnStart(

{

btnExportXML: doNotUseAjax,

btnExportXSLT: doNotUseAjax,

btnExportXSD: doNotUseAjax

});

var cancelAjax = false;

function clientButtonClicking(sender, eventArgs) {

debugger;

if (eventArgs.get_item().get_value() == "postback") {

cancelAjax = true;

}

function onRequestStart(ajaxManager, eventArgs)

{

alert(cancelAjax);

alert(eventArgs.EventTarget);

if ((eventArgs.EventTarget == "btnExportXML") && (cancelAjax)) { alert('TEST'); eventArgs.EnableAjax = false; }

if ((eventArgs.EventTarget == "btnExportXSD") && (cancelAjax)) { eventArgs.EnableAjax = false; }

//Uncomment the line below in case of a file download.

cancelAjax = false;

}

</script>

</telerik:RadCodeBlock>

CS:




public static void DownloadFile(HttpResponse response, Constants.DownloadFileType type, string fileName, byte[] data)
{
    using (var trace = new TraceManager("Default"))
    {
        try
        {
            response.Clear();
            response.Buffer = true;
            byte[] storage = data;
 
            switch (type)
            {
                case Constants.DownloadFileType.XML:
                    //document is xml
                    response.ContentType = "application/xml";
                    response.AddHeader("Content-Disposition", "attachment;filename=" + fileName + ".xml");
                    break;
 
                case Constants.DownloadFileType.XSLT:
                    //document is xslt
                    response.ContentType = "application/xml";
                    response.AddHeader("Content-Disposition", "attachment;filename=" + fileName + ".xslt");
                    break;
                case Constants.DownloadFileType.XSD:
                    //document is xslt
                    response.ContentType = "application/xml";
                    response.AddHeader("Content-Disposition", "attachment;filename=" + fileName + ".xsd");
                    break;
 
                case Constants.DownloadFileType.DOCX:
                    response.ContentType =
                        "application/vnd.openxmlformats-officedocument.wordprocessingml.document";
                    response.AddHeader("Content-Disposition",
                                       "attachment;filename=" + fileName + ".docx");
                    break;
 
                case Constants.DownloadFileType.EMAIL:
                    //document is email
                    response.ContentType = "text/html";
                    response.AddHeader("Content-Disposition",
                                       "attachment;filename=" + fileName + ".html");
                    break;
 
                default:
                    //throw new Exception("Unknown Placeholder type specified.");
                    break;
            }
            response.Cache.SetCacheability(HttpCacheability.NoCache);
            response.BinaryWrite(storage);
            //response.End();
            HttpContext.Current.ApplicationInstance.CompleteRequest();
        }
        catch (Exception ex)
        {
            trace.HandleException(ex);
        }
    }
}

Please help to resolve this issue.
