    Hi,

    we use V2012.1.326.35 of Telerik and our application run on a Virtual Machine and we access it through Windows Remote Desktop. If you look at the attached file, when I click on the button of my RadDatePicker to popup the calendar, the calendar appear behind my control. If I run our application directly on my computer, I tried to reproduce the problem without any success :( I remark that this problem occur with some other Telerik controls also like the filters dialog with the RadGridView controls.

    Thank's

    Hello Oliver,

    I have tried to reproduce the issue, but as you can see in the attached video with no luck. Attached is also my test project, it would be great if you can check it out and let us know if we are doing the same thing. Also any information about the virtual machine that you are using might be helpful to get to the bottom of this.

    Kind regards,

    Hi Georgi,

    after doing some other tests, the problem doesn't occuedr only with a virtual machine but also when we connect with Windows Remote Desktop on our customers computers (more than 1 customer). On my computer, I also cannot reproduce the problem but as you can see in my screenshoot the problem really exist.
     
    I don't know what to tell you exactly: Standard video card, 1 year or little bit more old computers, etc...

    PS: I cannot see your video, swf extension

    Thank's

    Hello Oliver,

    The video is recorded with Jing and you can open it with any web browser. It would be great if you can record a video on your own and show us the issue. Also do you know if this happens only on specific version of Windows or it can be reproduce on Windows 7 as well as on Windows XP?

    Hi,

    in my initial email, I included a screenshot showing the issue. Actually we saw the problem on Windows XP only, all of our customers use XP. What we did, in our environment, we build different virtual machine and we saw the issue when we connect on those VM using MSTSC.

    When we connect on customers, we use TeamViewer and we can see sometime the issue. Even if we are on cutomer site, we saw the problem many times.

    Thank's

    Hello Oliver,

    I have tested my project on Windows XP Virtual PC machine and also using TeamViewer but still I am not able to reproduce it. Maybe it can't just be reproduce in my project. It would be great if you can test the attached project on your virtual machine and see if the issue is present in it. If not can you, please put together some basic code where it can be reproduce, so we would be able to investigate it and fix it?
    Also any information about the window in which the DatePicker is could be helpful.

    Kind regards,

    Hi Georgi,

    I tried the attached project without any succes reproducing the issue :( I also tried to create a small project without any success too :( As I said, this problem occurred not only with calendar popup but also with other popup component like the filters dialog with the RadGridView component.

    Here is additionnals infos:

    - Those controls are mainly hosted in Grid that is mainly hosted in a RadWindow component
    - Window XP with a standard theme
    - We use Telerik OfficeBlue theme

    Hre is my main declaration of my window:

    In my XAML file:
    <telerik:RadWindow x:Class="DateTimePickerInWindow.Window2"...

    In my CS file:
    public partial class Window2 : RadWindow

    Thank's

    Hello Oliver,

    Unfortunately we have tried all of the described specifics, but we were not able to reproduce it. So I don't see how we can investigate it, test it or fix it with no way of reproducing it.
    The only reason I can think of that can cause this issue is that using Remote Desktop (or something similar) causes some delays and the DropDown is displayed behind the window.

    Hello guys,

    Sorry for digging up this topic, but I'm facing the same issue.
    After trying many different things I found out that removing the RadWindow and using the ordinary Window it worked out, but unfortunately we miss the fancy style of OfficeBlue, or whichever theme we use. Also, it takes place only on Windows XP (all my clients use it), on Win 7 works perfectly.

    Please, Is there any update regarding this problem?  I really would like to solve it once for all.

    Regards,

    Hello guys,

    After some research we have found out that it seems to be Microsoft related issue. Here you can find an support thread that sounds just like this one. There is an hotfix available and it would be great if you can give it a try and let us know if this fixes the issue.

    Kind regards,

    Hello Georgi,

    Thank you for your support. It might as well help us if the problem persists.

    Anyway, I found another possible cause, the dll Diagrams (picture enclosed) was kind of missing in my project. After I included it my application started working ordinarily on XP clients (at least so far). Curiously without this DLL the application works as supposed on Win7 and sometimes on WinXP. (go figure)

    Regards,
    Evandro
