All:

I have followed the examples for adding a RadContextMenu for the header row of a RadGridView and all is working great and it is very useful. However, I recently added this to another grid which contains a DataTemplate for the row details. Inside of this data template we have a small RadGridView displaying some other, related data; my problem is that the RadContextMenu.ContextMenu attached property is inheriting down to this grid inside of the Row Details and I cannot figure out how to turn it off.

I am assuming this is simply a property inheritance from WPF, but I have been unable to determine how to set it back to its default (no / empty) or if this is even possible. I have tried setting the property value explicitly to null on the row detail's grid, but that had no effect.

Worst case I can customize a context menu for the details grid, but was hoping to just turn it off altogether. If anyone could provide any guidance I would really appreciate it.

Thanks,
Adam

The background - I wanted user to be able to manipulate their photo via WPF apps but once it is uploaded to my website, I need those content to be translated into images so that I can save those images and refer to it via URL.

RadDocking DesignTime Broken?

I'm just starting a new project that would use the RadDocking library. Even the most basic example does not show in the designer. At times it seems like Visual Studio is hanging, but after 5-6 seconds it comes back to life. But the XAML Designer just shows a blank window no matter what I do.

PathData Direction

hi

I have a collection of objects on a visualizationlayer on the map which occasionally move and their path(previous locations) are stored in the viewmodel

and a collection of pathdata (the path of each of the above mentioned objects) binded to another visualizationlayer

when shown on the map each of this paths is just a collection of lines connected to each other and its not specified where the path starts and ends or where each line segment starts and ends. my question is : is it possible to some how show an arrow on each line segment declaring the lines direction or something like a showdirection property on each line segment.

thank you very much in advance for your help

Moving Object Disappears When Clustering Is Enabled

hi
well here is the scenario:
1- I have a Radmap
2- I have a Visualization Layer that :
    a) its ItemSource is bound to a collection of objects
    b) its item template is set to a usercontrol
    c) Clustering is Enabled on it with AutoCalculateClusteringThreshold=false and ClusteringEnabledThreshold=16
3- the objects mentioned in 2-a are moving objects meaning that their location is updated every half a second
the problem: when the zoom level is set to a level higher than the threshold mentioned in 2-c everything is okay and I see the object moving on the map BUT when the zoom level reaches levels lower than the threshold(which I assume is where the clustering methods come into action) the object blinks once or twice and disappears! until I zoom in and zoom out (and that's incase it doesn't move again or else it disappears again) .the item gets completely visible again when I zoom to levels higher than the threshold

thank you in advance for your help
