Issue when using UltraComboEditor in application accessed via Ericom
posted

Hello -

We have a .NET 2.0 Windows Forms application using .NetAdvantage 9.2 controls (9.2.20092.2083) that is accessed via Ericom (similar to Citrix).

We have found that when the application is not Maximized and the user clicks the drop down button on an UltraComboEditor a colored box (color varies depending on the server) is drawn on the users desktop.  The size of the box seems to match the size of the window.  This is an MDI application and only happens when the MDI child being used is not maximized in the MDI frame.

Depending on where this box is drawn and how large it is, the potential exists for a user to not be able to access anything on their TaskBar.  Additionally, if they minimize the application with this box on the screen and it is covering the TaskBar and or Start button it is near impossible to access anything else.

A similar issue occurs with UltraTabControl that have tooltips.

I do have a video that illustrates the issues if there is a way to get it to you. 

I have created a empty form (no custom code of any kind) except for a few controls, Infragistics controls and standard .NET Controls.  The .NET controls work fine but the Infragistics controls result in the boxes being drawn.  I can also provide the example form.

Any suggestions for addressing this are much appreciated.

Thanks.

    Hi John,

    You can attach a file to your post by going to the Options tab when posting. So you could attach a video that way (assuming it's small enough; there is a file size limit). You could also post some screen shots that way.

    I vaguely recall that there were some bugs when using some of our controls through Citrix and I am sure we made some fixes to our controls to fix some of those issues a few years ago. I don't remember exactly what those issues were, though. And I am pretty sure I've never heard of anything like the boxes you describe.

    Do these boxes show up in addition to the dropdown window? Or instead of it?

    Is the color of the box the same as the system tooltip color? If so, then it could be that the boxes are tooltips that are simply being improperly positioned or sized. If that's the case, then I suspect the fixes we made will help you, because I am pretty sure they had something to do with detecting the appropriate screen size and coordinates in a Citrix environment.

    So my first suggestion would be to you to update to the latest service release. The last service release for v9.2 was 20092.2119, quite a big jump from the 2083 build you are using.

    If that doesn't help, you could try upgrading to the latest version of NetAdvantage (2013.1). You could download the trial version and test it out to see if it fixes the issue before you buy, of course.

    Sorry, I thought I included the link.

    How to get the latest service release - Infragistics Community

    I'm afraid that video doesn't tell me much. It's not the same color as the tooltip, so it's probably not a mis-positioned tooltip window like I thought. Perhaps the color is the desktop color and the block is not actually a window that is covering the desktop, but just the opposite - an area where the desktop is failing to paint.

    One very interesting thing here is that the desktop image is still there. In know nothing about Ericom, but in my experience with Citrix, they typically do not show the desktop wallpaper on the client machine.
