Dears,

I'm using a PdfViewer and I hided the download button, but still visitor can see the path of the file from the page source.

How can I prevent visitors to see the file path, If any way to give the PdfViewer the file stream object instead of the path?

Note:
The file path is coming from database in string format.

Thank you for your help.

Hi all, 

currently we have the problem, that if we paste text with "Enter" in it, the br-Tag shows up in the HTML instead of the p-Tag. In the settings we choose new lines as paragraphs. 

We could reproduce this behaviour in the demo editor: 
https://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx

1. Select Paragraps

2. Copy a text with with paragraps

3. Paste it (Even if we use paste plain text)

4. See that there are br-Tags 

Is there anything we can do? 

Best regards,

Anna

The content of my grid is 100% dynamic, so using NeedDataSource is not an option.  I know the Telerik recommendation for advanced blah blah blah is to use NeedDataSource.  Not going to happen...which brings me to my question.. 

How to export the data in the grid, as it exists, to a PDF file without the NeedDataSource event?  Not overly thrilled about the possibility of rebinding either.  The grid could contain thousands of rows.  

Hello all, 

I have a problem with the RabTab control when I change the selected tab. The dll version is 2017.3.913.

The page structure is

RadMultiPage which contains 7 Page views and has the attribute RenderSelectedPageOnly="true". Inside each page view there is a radgrid control.

The issue is when I change the tab, the grid inside the pageview doesn't display. 

Here is the code

Default.aspx

I have a RadAsyncUpload and the function for OnClientValidationFailed is getting called with a wrong file size error even though the file is well within the size limit.

Markup

<telerik:RadAsyncUpload runat="server" ID="fUploader" PostbackTriggers="btnSendEmail,btnSaveDraft" OnClientValidationFailed="fileUploadValidationFailed"></telerik:RadAsyncUpload>

server side

fUploader.TargetFolder = uploadPath
fUploader.AllowedFileExtensions = New String() {"*.jpg", "*.png", "*.gif", "*.jpeg", "*.bmp", "*.tiff", "*.pdf", "*.gpx", "*.tcx"}
fUploader.MaxFileSize = 2500000

javascript

function fileUploadValidationFailed(sender, args) {
    var fileExtention = args.get_fileName().substring(args.get_fileName().lastIndexOf('.') + 1, args.get_fileName().length);
    if (args.get_fileName().lastIndexOf('.') != -1) {//this checks if the extension is correct
        if (sender.get_allowedFileExtensions().indexOf(fileExtention.toLowerCase()) == -1) {
            alert("File type selected is not allowed.  Valid file types are .jpg, .png, .gif, .jpeg, .bmp, .tiff, .pdf, .gpx, .tcx");
        }
        else {
            alert("File too large.  Max file size 2 MB.");
        }
    }
    else {
        alert("File type selected is not allowed.  Valid file types are .jpg, .png, .gif, .jpeg, .bmp, .tiff, .pdf, .gpx, .tcx");
    }
}

Hi,

i have attached a LoadingPanel to my RadScheduler.How can I get it to display when loading/saving  the AdvancedForm, but not for every single postback on the form. I have a multitude of checkboxes on there & getting the loading screen for every tick/untick is really slowing things down.

I've had a brief look at OnRequestStart, but I don't see how to narrow down the postback event being applied to the scheduler.

Thanks,

Ellie

The current Telerik version used in our project is (v.2012.3.1308.45 Dev). I am trying to upgrade this to 2020.2.617(Trial) version in Visual Studio 2019 using the steps mentioned in the link https://docs.telerik.com/devtools/aspnet-ajax/general-information/integration-with-visual-studio/visual-studio-extensions/upgrade-wizard but I encounter error mentioned below. I have also attached a screenshot of error window for your reference. Please help me with this issue.

An error occurred while running the wizard.
