Hi,

Simple question, how can I subscribe to MailMergeCommand so that I can find out where the file is being saved. 

Has there been any work on touch support for the Chart control? I found this old post that mentioned support being worked on in 2012 Q2.

The features we want to implement are:

• Swipe to pan
• Pinch to zoom
• Tap to place custom markers
• Drag to move custom markers

I could not find anything in the API documentation, could you give me any pointers as to how to implement this?

Hello !

I would like Drag and Drop between two RadGridView in MVVM Light.
I read many articles and many examples but I have difficulty to use DragDropManager.

I didn't found an example like my project (it isn't in MVVM or it use RadDragAndDrop, ...).

Somebody can help me please ?
Thank you !

Best regards,

When using a property grid, I have a DataTemplateSelector for properties that require my custom control to edit.  Upon initializing my control, I need a view model set, so I use AutoBindBehavior.UpdateBindingOnElementLoaded for that purpose.  Several times I have renamed a convenience setter for a property in my view model without renaming the corresponding dependency property, thus I was violating convention but nothing else.  Each time I did that, I would get a null reference exception.  I spent many hours trying to figure out what I did wrong.

I would be SOOO helpful if the exception in this case said "unable to find dependency property X"  I would've know exactly what I did wrong...

Hello,

After upgrading your components to version 2016.3.1024.40 (from version 2016.1.217.40 - I had no problems in that version), I'm unable to drop data on TextBox (regular WPF control).

In my scenario I need to drag some data from RadGridView to TextBox (which is acting as simple script box).

Could you help?

Best regards,

Hi,

I have a scenario where internet access is completely limited for security reasons, so ...

Does RadMap have the ability to load maps from a pc location or network location completely disconnected from intenet?

Ie, the RadMap control lets you define a Provider to a map file of some sort? Some RAR map cache or similar format?

Thanks....

I would like to know if there is a way to change the color of an event's background when it is selected.

Currently I'm using the themes Visualstudio2013 for gantt view.

for example I set one GanttTask Event background to gray, however it will show blue when  it is selected.

It seems that "EventContainerStyle" don't provide this property .

I have large chart, so i zoom it to scroll.

I want to print it using something like Telerik.Windows.Media.Imaging.ExportExtensions.ExportToImage(chart, stream, new PngBitmapEncoder());

I wonder will it save only current zoomed part or all chart? Because i need all chart, not only zoomed part.

Hi,

I've got an exception when dedocking a pane from a RadDocking. I've not been able to reproduce the issue but here's the stack trace in case it could help identify the problem :

Hi,

We are trying to integrate our tests that we have in our Local machines with our TeamCity server. Whenever we run the tests we get a null reference error "System.NullReferenceException: Object reference not set to an instance of an object". This happens for all the lines of tests in the tests. The tests run from local (and on others local machines), so I am not sure why they do not run from TeamCity Server. I am accessing the server as a normal admin user and executing the tests using MSTest.

Things to note:

• Telerik testingframework is installed on the server
• When we first tried to do the MSTest server complained about the fact that the .dlls that we were using (ArtOfTest.WebAii.dll, Telerik.TestingFramework.Hosts.Common.dll, Telerik.TestingFramework.Interop.dll etc) where not recognosed so we copied the local versions over to the server (as dependencies of a compiled project). When we tried to use the .dll that are on the server (either from Teleriks Bin folder or from the GAC/MSIL folder) they either failed or there was an errorstating that the  manifest definition does not match the assembly reference.
• The versions of telerik testing framework are different on the local machine to the server (local machine: v4.0.30319, server:  3.928.5)
• There are no issues with the user or the VM locking

Any help on this would be great. I think the problem is probably located in the way telerik is using the .dlls/libraries in the server machine, but I am nt sure how to fix this. We have looked at the instructions for setting the Framework up on a CI, but they do not seem to go into this level of detail.

Many thanks in advance for your help on this.

David
