    Hi everyone,

    out of nowhere my telerik controls stopped to display in VS Designer.

    Could you help me what should I do to bring them back?

    Thank you for your replies.

    Hello,

    May I ask you to share what is the version of the RadControls do you use? Do you get any errors in design time?

    Hi Didie,

    no, I do not get any errors. All the controls are fine in XAML, they just disappeared from designer (but not all of them, for example RadGridView is still visible in designer). It happened today in spite the fact nothing has changed within the project nor the solution. We are using the latest version of RadControls - downloaded few days ago.

    When I build and run the application it seems to be working as expected, but it is hard to design any form and style the controls when they are not displayed in designer.

    Thank you

    I have already tried that and it did not help. Do you please have any other idea how to solve this? Or at least what could have caused it?

    Thank you

    Hello,

    Does it happen in a single view, or in all of them? Would it be possible to limit the problem to a single control, commenting the controls definitions one by one? Does it happen if you create a new window and drag a control there?

    Hi,

    we tried to re-run the telerik configuration on the project and it worked. All controls are visible in designer again. On the other hand still no idea what could have caused this behavior.

    Thank you for your replies.

    This happened to me as well, and threw me into a gut-wrenching panic for a while. Thankfully I found this post and sure enough, re-running Telerik->RadControls -> Configure Project somehow fixed the problem. I too have no idea what could have happened. It was working fine last night, then opened the projected today and no RadControls would display (though the application ran and showed the controls just fine).

    Hello Aurelio,

    We are not aware of such an issue with the current version of RadGridView. May I ask you to perform the following steps:

            1. Open the project and remove all Telerik's references.
            2.     Save the project and close it. 
            3.     Open the project directory and delete "Bin" and "Obj" folders.
            4.     Open the project and add the references.
            5.     Build the project.

    Sometimes this helps to resolve the designer's errors and I hope that in your case will be that way.

    Hi,

    May I ask you to create a new project adding RadGridView to it? Do you get the same error? If so, may I ask you to send me this test project so that I can check it locally?
    You can open a new support thread and attach it there.

    Just experienced the same issue with VS 2017 and current WPF controls.

    I confirm that "Telerik > UI For WPF > Configure Project", then restart visual studio worked for me as well.

    Now if I could only get the demos to install...

    Hello Yu Yang, Robert,

    I am happy that you have managed to find a solution and the designer is now working as expected.

    Robert, though I am not sure what issue you are experiencing while installing our WPF demos, I suggest  you checking out the Installing WPF Demos article.

    If further assistance regarding the WPF demos is required, I would kindly ask you to open a new thread and post your enquiry in it, so the threads are kept consistent.

    Thanks in advance for understanding.

    If I do "Install" from page http://demos.telerik.com/wpf/ it frequently sticks at 4.85mb download, without any notification of why.

    If I do "Launch," I get the download ok but then the progress sticks at "1" when opening the demos application.

    As usual for medium to big companies, we have corporate-level firewall and anti-virus that may block some suspected file signatures or url's.

    After leaving it at "1" while I was typing here, it finally went to an error I could open in Visual Studio which reported a system.io exception with message: " 'Could not load file or assembly 'Application, Version=1.0.0.0, Culture=neutral, PublicKeyToken=5803cfa389c90ce7' "

    This is on Windows 10 Pro. I have no cache files in "~AppData\Local\Apps\2.0", nor is there even a folder there named "Apps." 

    I have no previous version to uninstall since upgrading this machine from Windows 7.

    I would like to have local demos, but not if I have to install SQL Server express to do so. I have SQL Server 2016 Developer edition installed.

    Thanks

    Hi Robert,

    Alternatively, you can use the SDK Sample Browser. It lets you browse and open individual demos directly in Visual Studio without the overhead of the entire solution or other external dependencies. 

    This approach lightweight and easy to explore, here's a screenshot on my end showing an example of checking out a GridView demo:

    Why can't these things have an administrative download with non-dependent local installer? (As opposed to web stub launch/install)

    Hello Robert,

    Since you can't seem to install any apps, you can get the full source code for those demos here. The SDK Sample Browser syncs up with that GitHub repo and does a fetch, it's the same code as you'd use in the local application.

    Another option you can use is to just get the full source code of the Product Demos, as a ZIP folder, from your account.

    Here are the steps:

    1 - Log into www.telerik.com
    2 - Go to the UI for WPF downloads page
    3 - Scroll down the "Resources" section
    4 - Download the following file: Telerik_UI_for_WPF_[VERSION NUMBER]_Demos.zip

    In that folder you'll find a full Visual Studio Solution with all the demos and the QSF (the framework that launches and displays the demos).

    Let us know if you have any further trouble.

    Hello guys,

    here is the fastest solution for this issue

    Follow the below steps:

    1- From the Solution Explorer open the design code ( Example: FormName.Designer.cs )

    2- Copy the whole content to external text file and save it for later use.

    3- Open the form which have the issue and click on empty space on the form and press CTRL + A to select all the controls.

    4- Press CTRL + X to cut all the controls and then the form will be empty.

    5- Press CTRL + V to paste them again on the same form

    You will notice all the controls came back to their places as nothing happened but actually they lost their connection with their functions.

    6- Now save the form and close it then open the designer code file again and restore the contents you saved in the text file.

    7- Save and open the form again it will work as it was before.

    hope this help

    Hello Mando,

    It appears you're speaking about Winforms application. The issue in this thread is for WPF, which doesn't have a designer.cs file. Instead it uses XAML for the UI and a cs (or vb) code-behind.

    I recommend sharing that nice workaround in the UI for Winforms forums here.

    Hello Lance,

    Yeah I know it is WPF here but I think it is the same issue and the same solution except the XAML instead of designer, Will be so easy for developers to know the different

    and they can use almost the same steps

    however I posted it here
