I would just like to know how many levels I can drill down to in a chart. I read something about a bug that only lets you define and use 2 or 3 objects of type ChartHierarchicalViewDescriptor, but that seems like it would only apply if you had a different data structure at each level of the drill down.

I'm binding a chart to data built from an self-join in a database, so each level is the same as the previous. Will I be able to create one ChartHierarchicalViewDescriptor that works for as many levels as I have?

Thanks!

Hi guys i'd like to know on how to add empty cells at the bottom of the grid where the the user can add. It could be textbox or combo box. THanks!

I am testing the demo version of the GridView control (Q2 2011 version) and by integrating it into my current project. I am running into an issue though, because my current implementation makes heavy use of TypeConverters to display data in WPF controls. To help explain my question, lets assume a couple of things:

First, we have a generic superclass called Super, which has a property that is an ObservableCollection<Super> which is called Stuff. 

In another assembly, we have some generated code that defines subclasses of Super, each with their own set of properties. Some of the properties of this subclass have custom type converters also defined in the same file (these type converters are automatically generated). For example:

I abbreviated some of the methods but assume that they convert Int64s to Strings and vice-versa.

In addition, these subclasses fill the Stuff collection with some elements. Now, in my application we only refer to these subclasses by loading the assembly programmatically and using reflection.

When we pop up a GridView and bind it to the Stuff collection like so: 
We get what we wanted to see, all the properties of the subclass are reflected on and columns are automatically generated for them. We can edit them and ones that were not Browsable don't show up, ones that are ReadOnly can't be edited, etc. The only downside is that our custom type converters do not appear to work, and in fact it seems that they are never called by the GridView. We know that the TypeConverter code does work, as we have used them with other WPF controls for quite some time now without issue.

We are willing to change the way we define our TypeConverters if necessary (given that the WPF PropertyGrid that you provide would also support the TypeConverters given the same change), but we can not feasibly change to using IValueConverters, as that only provides us with ConvertTo and ConvertFrom methods, and what we really want is to be able to use the StandardValuesCollection (or something similar) that TypeConverter provides us, to avoid writing a lot of extra code in order to handle this conversion ourselves.

I saw a thread that somewhat pertained to this issue here, which claimed that TypeConverter support was added in the latest release but the author never wrote back to confirm if the changes worked for him or not. Please let me know what steps we should take to solve this issue. We are very interested in purchasing your product because everything else about the GridView seems to work perfectly for us, but this is a problem which must be solved. Thanks in advance.

Hi all
RadColorPicker does not work fine in the collasped state of RadRibbonGroup.
Thanks
Deepak

I have an application menu with a RadRibbonDropDownButton(expands to the right). The content of the RadRibbonDropDownButton are a couple of RadRibbonButtons and then another RadRibbonDropDownButton(also expands to the right). In other words I have a RadRibbonDropDownButton within another RadRibbonDropDownButton.

This somehow makes the small arrow on the inner RadRibbonDropDownButton("direction arrow") to point downwards. I have tried to set the DropDownPlacement="Right" and the DropDownButtonPosition="Right" but still the direction arrow is pointing downwards... Shouldn't the the direction arrow be pointing right? Is this somehow a bug caused by the fact that I'm having one RadRibbonDropDownButton within another RadRibbonDropDownButton?
(I have also tried to replace the inner RadRibbonDropDownButton with a RadDropDownButton)

The "direction arrow" on the outer RadRibbonDropDownButton is correctly pointing to the right...

Hi

I'm pretty new to WPF, and was hoping that I might get some help with relation to a docking panel.

I am essentially trying to create a panel bar which will alert users when they have to approve something. I'm imagining something very much like those in visual studio. Essentially a bar which is collapsed most of the time, but on hovering over it, it expands. But I also need to be able to expand it (and prevent it from collapsing - I'm guessing via the ispinned property) via c# when various conditions are met, say 20 minutes until the next approval is due.

Is this possible?

I can send a code sample of what I have already if need be.

thanks

Hi !
We use the ScheduleView Q2 2011 in a scenario where all appointments are recurrent, with the same configurable recurrence length. We have a crash that we can reproduce repeatedly when double-clicking in the schedule to add a couple of appointments, then changing the recurrence length. It won't necessarily do it the first time, but playing around with the control eventually yields the crash.
The exception is:

System.NullReferenceException was unhandled

Hi,

I have been stuck with this issue for 3 days now and I need to move on. I am attempting to convince a client to use Telerik + Prism 4 for a new project they are undertaking, however I cannot even show them how to add a document to a RadDock when they click a button in the Ribbon Bar.

All of my problems center around our friend, the RadPaneGroupRegionAdapter and the implementation provided by Telerik. It simply does not work. I can register the views (documents) successfully on startup of the application, however as soon as my command attempts to execute the following code:

m_RegionManager.RegisterViewWithRegion(WpfPrism.Infrastructure.Helpers.RegionNameHelper.Document, typeof(Views.Search)); 

All is lost and I get the following error:

Here is a link to where the solution can be found WpfPrism

When I set IsSynchronizedWithCurrentItem="True", the current row gets the row selection indicator (chevron). However, I have extended selection enabled - to be able to Ctrl+Click-add multiple rows. In this case, only the first row I select gets the chevron - is there a way to extend this to all selected items? (or restyle the area where the chevron is displayed entirely)
