Hi
Sometimes i need to use the them colors for border brush, so the color changes if the them changes

Is that possible here?

Thanks,

Hey,

I am evaluating the telerik chart component (trial version) for its suitability for our software project, and can not bring the RadCartesianChart to work.  

I am trying to put a new view atop of an existing viewmodel, and bind the chart data to a property of type ObeservableCollection<KeyValuePair<int, double>>. When the collection is empty its ok, but when trying to populate it, I get
ArgumentException: Dynamic getter is not supported for value types. 

Any idea why this happens and what the solution is? 

My code: View:

And the view model:

Hello

I would like to know if it is possible to use a single data source with the tree list view and describe the self referencing parent-son relationship in the data (ID property and ParentID propert), in opposition to having each node contain a property listing all of its sons.

I managed to do this with the rad grid view, but this is not satisfactory to me, i want to state which objects are root, in the grid view the nodes appear in both the first level and under their parent (I found this to exist in your examples as well), in addition the control operates as a master detail with several levels.

This was actually asked before on this thread:
http://www.telerik.com/community/forums/wpf/treelist/self-reference-with-datatable.aspx

but no actual response was made.

Thanks in advance.

Hi 
I know how to switch themes but the strange thing that the already opened windows does not affected by this line
StyleManager.ApplicationTheme = new Windows8Theme();

Is that true that i can't change the theme for the already opened windows?

Thanks,

Hi everyone,

I have a button declared in a Prism region with a command declared in RadScheduleViewCommands. This button is used to advance the displayed date in my ScheduleView. 

<Button Label="Next day" Command="scheduleView:RadScheduleViewCommands.IncreaseVisibleDateLarge"/>

My RadScheduleView is declared in another region. This region can be shown or not, because it is inside a tab control. My problem is when I show my RadScheduleView in the tab, my button is disabled until the user clicks in the RadScheduleView. In this moment, the button is enabled and functional.

I need to change this behavior to enable the button in the moment the ScheduleView is shown on the screen, avoiding the user to click on the schedule. Is this possible? How?

Thank you!!!!

EDIT: The title of this post is wrong, The button is always visible. My problem is the IsEnabled property of the button. Don't know how to change the post title, sorry!

Hello,

I have RadGridView working with DataPager. I encountered a problem when tried to select all items in RadGridView. To do this I am going through each page of DataPager and add items to GridView SelectedItems collection. It seems to work, but after that if I try to switch page or deselect any item - my selection is removed. 

What is right approach to do what I want?  

I've downloaded and installed the WPF controls.

When the demo is run, it crashes. At first I thought that is was something I was doing, but each time I tried it I did something different. In the end, I just started the demo and did nothing and it still crashed.

It appears that it will always crash after about the same period of time regardless of the level of interaction I have with it.

This machine has XPPro SP2, V2008SP1 .Net v3.5SP1 installed.

Is there something I've missed?

Hi,

I am just starting on a trial version of telerik so I am still new to many concepts.

Here are some questions I like to ask about radmap:

1. I managed to load my geotiff image using UriImageProvider and specifying the geobounds. However, is it possible to load the geotiff image directly, i.e. without me having to use another tool to read off the geotiff header to find the location boundaries of the image.

2. My geotiff image is not a perfect square / rectangular image, that is, there are black background on pixels that have no information. How do I render the images such that these pixels show up as transparent since I be overlaying the image on top of my base map. With Arcmap, I can set this through the image properties. How do I do it with radMap?

Thanks!

Hello,

Because of broken Drag on Drop on GridView, I used now latest internal Build 1106.
I cant serialize my GridView now (Build 1029 works fine).

Hi there

the tree lines in RadTreeView are shown broken (indented to the right about 1-3 pixels) when I use a HierachicalTemplate for the TreeViewItems. Why?

I would like to attach a screenshot, but I dont't know how to do that.

Regards
Felix Brueckner
