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.

How can I disable dragover capture on RadTreeListView columns headers in case like example below? I would like to not have impossible drop visual in case of dragging over column headers.

Example:

Hello,

it is possible integrate the RadChartVIew with RadGridVIew?

Something like this (but using RadChartVIew instead of RadChart): 

http://docs.telerik.com/devtools/wpf/controls/radchart/how-to/integration-with-rad-grid-view

My objective is to reload the Chart every time when the RadgridView is filtered. There are someexamples about this topic?

Thank you!

Regards

Hi, I am successfully able to display the custom merge field(inserts a table into the document) into my RadDocument. The problem I come across is that when I try to save or mail merge I am presented with an error

Am I doing anything wrong while creating a MergeField? Is the xamlserializer causing the error?

I have a Floating Radpane (2.gif) and I want this to fit the content inside. Is it possible to make it behave like the 1.gif grid?

What I want is for the width and height to be dynamic depending on the content.

The RadPane structure is as follows:

Thank you
Gerard.

Hi,

I've written a custom provider (using a custom TileMapSource). I'm using EPSG900913Projection but the tile source I'm using does not have data for the entire world. The first problem I have is that when I first render the map it's using GeoBounds for the entire world. The problem is that I don't statically know the extent of the data source until I load the map, so I can't set the GeoBounds for RadMap and my custom provider in xaml. I've tried hooking event handlers for my user control "Loaded" event, also in RadMap.InitializeCompleted where I've tried to set the GeoBounds for both the RadMap and the custom provider but still the first time the map renders it covers the whole world.

I'd also like to limit the zoom range the user can use i.e. I'd like to stop the user zooming out more than one zoom level from the initial data extent. Again, because the data extent is not statically known I can't set the min and max zoom to fixed values. Is there some way to calculate the zoom level corresponding to the available data extent?

I have wired up a refresh button that when clicked calls RadMap.SetView passing a locationRect that I've constructed from the data available, and that correctly sets the view (and zoom level) for the map.

Can you suggest where I might be going wrong?

Thanks,

Pete

Hi guys!
I found a problem regarding text size change and following text selection.

These are the minimal steps to replicate the bug:
* Start WPF demo and select RichTextBox demo
* Select first paragraph under "Overview": from "RadRichTextBox is a control" to "bookmarks and comments."
* From the upper toolbar, change font size to 20
* Scroll down to the second paragraph ("The control can preview... tweaking of images."), you will be only able to select words from the first and fourth line but NOT from the second or the third.

The problem disappears immediately after using another format command or if you change the paragraph text. It seems to me that font size change doesn't invoke a document measure/rearrange.

Thanks for your assistance.

Hi

I am trying to create my own custom column based on GridViewBoundColumnBase to use with RadGridView.

When using a column like GridViewDataColumn intellisense knows that the Binding in DataMemberBinding uses the context of an item specified in its parents RadGridView's ItemsSource. This gives me the proper suggestions from intellisense to bind to.

With my custom column I am unable to replicate this behavior. I only inherit the datacontext from the parent RadGridView. How can I get around this?

(PS: I need to create a custom column, I do not want to set the DataTemplate of GridViewColumn specifically for every table)
