I have telerik 2011.3.1305.35 -> Q3.
In a sharepoint 2010 visual webpart I have a RadTreeView control, when some particular menu options are selected I want to open radwindow(s) which has an asp:updatepanel and within which I have another radtree,radgrid,repeator, RadAynscUpload (not all in same window).
Folowing is the code I have for this requirement:
Issues I am facing currently:
1) Every time I click on any of these menu options the page is getting refreshed and then radwindow is getting opened, Can we avoid page refresh and just simple open radwindow?
2) One of these RadWindows has RadAsyncUpload (for multiple file uploads), when I select the files to be uploaded I am getting a javascript error saying 'Syntax error' but I can see the file uploaded to the control then when I click on the Upload button my code says the uploadedfiles count is zero. I know there are web.config changes to be done for radupload is that the same case for RadAsyncUpload, can you please specify those?
I have also tried asp:fileupload (even though its not multiple upload) it is uploading the documents correctly but it is closing the radwindow even though I specified trigger for the button.
Code:



protected
void rtvDocuments_ContextMenuItemClick(object sender, RadTreeViewContextMenuEventArgs e)
        {
  
            RadTreeNode clickedNode = e.Node;
  
            switch (e.MenuItem.Value)
            {
               case "AddDoc":
                    LoadAllGroups(rtvGroupstoAddDocs);
                    RegisterStartupScript(RadWndwUploadDocs.ClientID);
                    break;
                case "AddExistingGroup":
                    LoadAllGroups(rtvAllGroups); //loads all the groups
                    RegisterStartupScript(winGroupBrowse.ClientID);
                    break;
                case "AddExistingDoc":
                    LoadAllDocuments(); //loads all docs in grid
                    RegisterStartupScript(RadWndwAllDocs.ClientID);
                    break;
                //Other Cases here
             }
  
private void RegisterStartupScript(string RadControlId)
        {
            string script = string.Empty;
            script = "function f(){$find(\"" + RadControlId + "\").show(); Sys.Application.remove_load(f);}Sys.Application.add_load(f);";
            ScriptManager.RegisterStartupScript(Page, Page.GetType(), "key", script, true);
        }
  
//If files uploaded and on upload button click, submit the documents to repeator and then upload them to SP document library.
//I tried both the control, when debugging AsyncUpload count is zero and getting "syntax error" on the page
//FileUpload uploads succesfully but closes the radWindow, but I want the window to be showing up, If this is the only solution and if RadAsyncUpload is not helpful for me.
        protected void SubmitButton_Click(object sender, System.EventArgs e)
        {
//If RadAsyncUpload is used.. I want this to be working because of multi uploads requirement.
            if (RadAsyncUpload1.UploadedFiles.Count > 0)
            {
  
                labelNoResults.Visible = false;
                Repeater1.Visible = true;
                Repeater1.DataSource = RadAsyncUpload1.UploadedFiles;
                Repeater1.DataBind();
  
                List<string> lstFileNames = new List<string>();
                foreach (UploadedFile file in RadAsyncUpload1.UploadedFiles)
                {
                    lstFileNames.Add(file.FileName);
  
                }
                //AddedControl ISODocuments to SharePoint document library
                AddDoc(lstFileNames);
  
            }
            else
            {
                labelNoResults.Visible = true;
                Repeater1.Visible = false;
            }
  
//If file upload is used.
 if (FileUpload1.PostedFile != null)
            {
                string siteUrl = SPContext.Current.Site.Url;
                using (SPSite siteColl = new SPSite(siteUrl))
                {
                    //Get SPWeb object representing a particular website
                    using (SPWeb webSite = siteColl.OpenWeb())
                    {
                        try
                        {
                            webSite.AllowUnsafeUpdates = true;
                            webSite.Lists.IncludeRootFolder = true;
                            //Get the document library in which documents will be uploaded
                            SPList docLibrary = webSite.Lists["UpLoadedDocuments"];
                            // objFileUpload is asp.net FileUpload Object
                            Stream FStream; string fname;
                            FStream = FileUpload1.PostedFile.InputStream;
                            int basenamestart = FileUpload1.PostedFile.FileName.LastIndexOf(@"\");
                            fname = FileUpload1.PostedFile.FileName.Substring(basenamestart + 1);
                            //Upload files into SharePoint document library
                            SPFile file = docLibrary.RootFolder.Files.Add(fname, FStream, true);
  
                            file.Update();
                        }
                        catch
                        { }
                    }
                }
            }

I have added the radprogressmanager and radprogressarea to RadAsyncUpload and updated my web.config file and disabled the flash dependency as mentioned in few blogs eg:
http://www.telerik.com/support/kb/aspnet-ajax/upload/906-ajax-callback-error.aspx and
http://www.telerik.com/community/forums/aspnet-ajax/upload/radasyncupload-control-asking-for-login-in-sharepoint.aspx

But still RadProgressArea never stops loading and I get the same 'Syntax error' (Please find the attachment), What else I am missing?



<
telerik:RadProgressManager runat="server" ID="RadProgressManager1" />  
                                               <script type="text/javascript">
                                                   Telerik.Web.UI.RadAsyncUpload.Modules.Flash.isAvailable = function () { return false; }
  
                                               </script>
                                                           
                                               <telerik:RadAsyncUpload runat="server" ID="RadAsyncUpload1" OnFileUploaded="fileUploaded" />  
                                               <telerik:RadProgressArea runat="server" ID="RadProgressArea1" />  
                                                                                                                                    
                                                <%--<asp:FileUpload ID="FileUpload1" runat="server"  />--%>
                                                   <asp:Button runat="server" ID="SubmitButton" Text="Upload files" OnClick="SubmitButton_Click" />

You can add the AsyncUpload and ProgressManager to a new VisualWebPart.
Then you can test if the upload works (uploads files) firstly with,  and then without the ProgressManager(simply remove it from the webpart) – I am sure that this will help you find out what causes the error.

I tried using Updatepanels -> Control templates -> Uplad button and outside button panel I used triggers which takes care of postback.....I think it works in ASP.net application, but if you are into Sharepoint and opening a usercontrol in radwindow then this wonot work, meaning you would not see the flicker (postback) but the document will not get uploaded and hence I created an application page and opened it in radwindow and hence on button click my application page will get refreshed not my original page ....

Hi,

I tried to reproduce the issue you described but to no avail. Would you please share the exact isolated code that will help us observe the described issue that works properly in ASP.net application and does not work in SharePoint? Please remove all the controls and code that are not directly connected to the issue so we can inspect it and be more helpful.

Regards,
