Hi,

I am facing a problem while using the RibbonView and populating it's items using MVVM.

The problem is specifically related to the Contextual tabs, and occurs only when using an ItemTemplateSelector to populate the RadRibbonButtons. The problem is that only a TextBlock is generated instead of a RadRibbonButton in the contextual tabs. The ItemTemplateSelector works fine with normal tabs but in the case of contextual tabs, the ItemTemplateSelector isn't even accessed and just a text block is generated instead. The problem goes away when I place a single ItemTemplate instead of using an ItemTemplateSelector.

I have posted regarding this in another thread in detail, with reference to a project attached from you guys that also has the same problem. Here is the link to that post:

Hi,

I have an Silverlight application using an old Telerik library (v. 2012.3.1017.1050) which will quite a bit of work to upgrade to the latest Telerik controls.  Now that people are upgrading to Windows 10 we are running into an issue where the browser will lock up when someone presses one of the RadRibbonButtons in the ribbon control.

It turns out that the problem only occurs on systems where the "Touch Keyboard and Handwriting Panel Service" is running.  By disabling that service we don't run into the problem.  Obviously this isn't a very good solution.

Is there a way to work around the problem without having up either upgrade our Telerik controls for this project or have people disable the service?

Cheers,

Clint

In the Q1-2014 release notes, it is mentioned that the screentip now supports "Press F1 for help" functionality but I am not able to find an example in the documentation nor online. Can you point me to a working example or documentation that outlines this feature.

Thanks,
Shawn

In RadPane under RadDocking control, header text is visible only up to certain characters.

I am not able to make longer text as header for RadPane.

Will you help to achieve this?

Thanks in advance.

Hi, 

I'm would like to know if it's possible to stop the RibbonView from disappearing completely when the window has been shrunk beyond a certain point. I've tried using CollapseThreshold, and I've also specified that the Buttons can only use the large variant. This works to keep the buttons large, but at a certain window size the RibbonView will still disappear completely. I would like to modify this behavior so that the RibbonView never collapses. If this can be a system wide style or property change, that would be the optimal solution.

Thanks you for your time and I look forward to hearing from you soon.

Regards, 

Dan

Hi guys,

Is there a way to change the ApplicationMenu position ?
I want to put it at the right of the RibbonView with the tabs on the left.

Thanks,

Is there any way to add an empty tab to the ribbonview? I have a few tabs that need a number of controls in them, but then I have one tab that I don't need any controls in... so it is just sitting there empty. I have tried collapsing the ribbon when moving to that tab, but it works fine in debug but then crashes the app when deployed. Is there a way to add a tab just for navigation without having any space for controls in it?
