Workflow:

1) Client clicks on RadWizard Finish button
2) JavaScript code in either OnClientButtonClicking or OnClientButtonClicked performs some asynchronous background processing => file upload
3) RadWizard waits for JavaScript code to complete its operation (callback or something else – we are waiting in the OnClientButtonClicking or/and OnClientButtonClicked event handlers)
4) After successful operation RadWizard continues with the postback => OnFinishButtonClick server side event is called and data is saved in the database

Is it possible to achieve above-described workflow (or something similar) in the JavaScript and RadWizard ASP.NET AJAX control?

First let me post the error I'm getting in logs:

RadAsyncUpload could not create App_Data folder. Ensure the App_Data's location is writable or set the TemporaryFolder property to a writable location.   at Telerik.Web.UI.RadAsyncUpload.CreateAppDataFolder()     at Telerik.Web.UI.RadAsyncUpload.EnsureDefaultTemporaryFolderExists()     at Telerik.Web.UI.RadAsyncUpload.OnPreRender(EventArgs e)     at System.Web.UI.Control.PreRenderRecursiveInternal()     at System.Web.UI.Control.PreRenderRecursiveInternal()     at System.Web.UI.Control.PreRenderRecursiveInternal()     at System.Web.UI.Control.PreRenderRecursiveInternal()     at ....

And here is something about my scenario. I have SharePoint application with some pages containing Telerik controls. Two of the pages contain RadAsyncUpload control. Everything is working fine except situation when I'm browsing two mentioned pages. I receive 403 forbidden error (above I posted what I found in logs). It's worth mentioning that I'm running web application with user account (local admin, not built-in account) as application pool identity and we have Form Based Authentication set up. Even if I try to access the page with administrator account it fails. I've tried to add write permission to app_data folder for app pool identity user but it didn't work. Any other clues what permissions should be set up?

Hi Team,

I am using Telerik - R32020.3.915 with .Net-4.8

Currently we are migrating Telerik.WebControls.RadGrid to Telerik.Web.UI.RadGrid, with help of below article.

https://www.telerik.com/support/kb/aspnet-ajax/grid/details/migration-from-radgrid-for-asp.net-(classic)-to-radgrid-for-asp.net-ajax.

My project has a skin="Sample" ,Exists in project skins folder.when I try to render with that ,no changes are seen.

Code Snippet:

     

<telerik:RadGrid ID="ItemRadGrid" AllowCustomPaging="true" AllowFilteringByColumn="True" AllowPaging="True" AllowSorting="True" 
              AutoGenerateColumns="False" GridLines="none"
              GroupingSettings-CaseSensitive="false" PageSize="50" Skin="Sample" 
              ShowGroupPanel="false" UseEmbeddedScripts="false" Width="100%" runat="server">
   

    <MasterTableView CommandItemDisplay="Top" DataKeyNames="Guid" Width="100%" AllowNaturalSort="false">

Error:

Telerik.Web.UI.RadGrid with ID='ItemRadGrid' was unable to find an embedded skin with the name 'Sample'. Please, make sure that the skin name is spelled correctly and that you have added a reference to the Telerik.Web.UI.Skins.dll assembly in your project. If you want to use a custom skin, set EnableEmbeddedSkins=false.

Tried by removing and adding reference telerik.skins.dll ,but still issue exists,

if we try to set EnableEmbeddedSkins=false, no skin is rendered.

If there is property implemented for skins ?

Can anyone please help on this?

*** Update from 17 Jan 2018 ***

The problem discussed below has been fixed in R1 2018 (2018.1.117).

The new Chrome 61 introduces some breaking changes which may lead to some of the following errors when the browser is scrolled and the resize handler of an appointment is clicked:

Placing the following JavaScript override before the declaration of the Scheduler should resolve all of the above issues:

Hello,
I am new to Telerik and I am currently supporting an ASP.NET application, I got a task in order to locate the files that were being uploaded by the application.
Reviewing the code I am making use of <telerik:RadAsyncUpload> using OnFileUploaded and InputStream.
I know that InputStream allows me to make the insert in database and process its content from the application. The doubt I have is where are the files that are uploaded using InputStream stored internally or where are they located, considering that it allows me to access the content of the uploaded files without saving them in a temporary location?

P.S.: I tried to check the App_Data\RadUploadTemp folder in my project but the files are not found.  

I would greatly appreciate your help, as I need to validate what documents are there and so on.

This is my code:

<telerik:RadAsyncUpload ID="RadAsyncUploadDocuments" runat="server" MaxFileSize="10485760" 
            MultipleFileSelection="Automatic" CssClass="multipleDocUpload" OnFileUploaded="RadAsyncUploadDocuments_FileUploaded" 
            Localization-Cancel="<%$Resources:cancel %>" Localization-Select="<%$Resources:select %>" Localization-Remove="<%$Resources:remove %>" >
        </telerik:RadAsyncUpload>

        <div class="doc_upload_buttons">
            <asp:Button runat="server" CssClass="action_button" ID="confirmUpload" OnClick="confirmUpload_Click" Text="<%$Resources:confirmUpload %>"/>
        </div>

 

protected void RadAsyncUploadDocuments_FileUploaded(object sender, Telerik.Web.UI.FileUploadedEventArgs e)
        {
            var Documents = Session["Documents"] == null ? new Bll.DocumentsCollection() : (DocumentsCollection)Session["Documents"];

            byte[] bytes = new byte[e.File.ContentLength];
            e.File.InputStream.Read(bytes, 0, (int)e.File.ContentLength);

            var document = new Bll.Documents();
            document._acprocessId = _acProcess.AcprocessId;
            document.AddedbyDate = DateTime.Now;
            document.AddedbyUsername = _user.UserName;
            document.AddedbyUsertype = (int)_user.ActiveReviewProcess.PermissionLevel;
            document.DocumentType = e.File.ContentType;
            document.AddedbyDate = DateTime.Now;
            document.Lastmodifieddate = DateTime.Now;            
            document.Path = e.File.GetName();
            document.Title = e.File.GetNameWithoutExtension();

            var documentId = document.Insert();
            document.DocumentId = documentId;
            var documentData = new Bll.DocumentData();
            documentData._documentId = documentId;
            documentData.BinaryData = bytes;
            documentData.Insert();

            Documents.Add(document);
            
            Session["Documents"] = Documents;
        }

        protected void confirmUpload_Click(object sender, EventArgs e)
        {
            UploadDocumentsSession _uploadDocumentsSession = new UploadDocumentsSession(_acProcess);
            _uploadDocumentsSession.Documents = Session["Documents"] as DocumentsCollection;
            _uploadDocumentsSession.CurrentDocument = _uploadDocumentsSession.Documents[0];
            _uploadDocumentsSession.UpdateSession();
            Response.Redirect(string.Format("~/{0}/DocumentManagerDashboard.aspx", _user.UserLevel >= SiteEnums.UserLevel.CCAReviewer ? "Admin/Processes" : "Public"));
        }

I am having a problem with RadGrid' scrolling position.

I want the header to be fixed. But they should move (scroll) horizontally, but not
vertically.

As it is a Telerik control I used their example (See below)

http://www.telerik.com/DEMOS/ASPNET/Prometheus/Grid/Examples/Client/Scrolling/DefaultCS.aspx

But it is helpless to me. The same thing I have applied, But when i fixed the header with the property  UseStaticHeader="True"  the headers are fixed.
I have also applied the container table property  style="table-layout:fixed".  After that they are not moving or scrolling horizontally nor vertically.

Please try to solve my problem, I am stuck.

You can see what problem I am facing. See the image below.



Please help. Its really urgent.

In my login page, I would like to hide the RadMenu which resides in the Master page in a RadPageLayout column.

Currently, the LayoutColumn holding the RadMenu has a Span of "2".  The RadMenu is in a LayoutColumn with a Span of "10".  Both exist within the same LayoutRow. 

When I set the RadMenu.Visible property to "false", the parent LayoutColumn is still rendered and while the RadMenu is not visible, the space it occupies is.  This forces the login form to appear off-center.

I have implemented a crude padding-right value which makes the visible login form to appear to be centered.  This is not a desired approach.

Is it possible to hide this LayoutColumn, server-side, on the login page so that the form isn't off center, or maybe a better solution to achieve the desired functionality?

Thank you, in advance.
