Hi,

i use the RadSchedule view with an MVVM, I group my appointments by Name of the customers. This works fine. I can add and remove
a group by clicking on the customer. But if I change to timeline-view this does not work. I see my selected groups, but I can't remove or
a one. If I switch back to month- or week view grouping is fine again!

Thanks
Best Regards

Hi,

I have a GridView bound to a ObservableList<DynamicObject>. I need to use DynamicObject since there could be undetermined number of columns displayed in GridView. The binding to data works fine.

I would also like to notify user which rows are containing invalid data. When using regulkar types and DataAnnotations everything works fine. How can I achieve the same result with DynamicObject?

Only requirement is if data exists or not. All data are of string type, If required for UI validation, I can expose bool properties (like IsValid)

Hi,

I want to update the data in RadPivotGrid cells.How to customize the Pivot Grid and make it editable on click/double click.
Please suggest. Thanks!

Hello.
We have a RadDocking control with multiple RadPanes in a RadPaneGroup.  Each RadPane contains a GridView.  We have an implicit style which works as expected.  The RadPanes are dynamically added to the RadPaneGroup on demand by the user.  Each time a RadPane is added the GridView is styled correctly.

When we implemented the PersistenceFramework we ran into an issue where the RadPane which is selected upon start-up gets the default style applied.  If I create a new RadPane it will be styled correctly as described.  I then save my layout and terminate the application.  When I start the application and we call  LoadLayout on the GridView and Load on the PersistenceManager.  And again that RadPane which is selected will have the default style applied to the GridView while the other RadPanes have the implicit style applied.

What would be a reason for this?

Thanks
Paul

Hello,

I've extended the RadDocking and I want to entend the RadPane too.
How can I set the RadDocking to create the CustomRadPane instead RadPane?
(In RadTabControl I've overrided the GetContainerForItemOverride in order to create CustomTabItem)

Hello Again;

I've recently hit up against another wall, in an attempt to use FluidContentControl within my TileViewItems I seem to lose data binding, charts that worked outside the control's properties no longer receive data, and same for data grids, I'm not sure how to proceed. The following is an example of my xaml (the small is meant to be 'blank' while the medium and large share the same content since I was experimenting with the controls), the chart is tied to an observable collection of objects each of which has an observable collection of 'dates' and 'decimal values' for which to populate the chart.


Your assistance is appreciated.

Hi,

I have bound to a TreeListView a collection of instances that raise the PropertyChanged from a thread that is not the main UI thread (the event is raised from a FileSystemWatcher event). When PropertyChanged is risen I meet the following exception:

InvalidOperationException was unhandled: The calling thread cannot access this object because a different thread owns it.

It really surprised me because I've previously bound other telerik WPF controls in an analogue situation and they worked flawlessly. Having a peek on GridViewRow.BeginProcessDataItemProperty I've noticed that it makes a call through the Dispatcher (which should avoid the exception) but the call to retrieve the dataItem for the row is outside the Dispatcher.BeginInvoke and that's (I pressume) the cause of the exception.

I don't know if this is intended behaviour or just a little bug but any feedback would be greatly appreciated.

Thanks in advance.

In WinForms there is (or was?) an attribute "[PasswordPropertyText(true)]" for displaying string properties as "*****" or something like that. How can I achieve this with WPF PropertyGrid?

Hi, I have a RadPropertyGrid with a combination of predefined and auto-generated properties organized in groups. I'm trying to implement a feature that remembers expanded/collapsed state of each group.
There's no problem with saving those states, a simple foreach on GroupDefinitions collection with all the groups is sufficient when a view is closing. But I can't find an event to subscribe to on the RadPropertyGrid when the view is being generated and GroupDefinitions collection is not empty. I have tried Loaded, Grouped, IsVisibleChanged and many more but no luck so far. Only if I pause an application when the view is already showed I can verify, that GroupDefinitions collection is indeed not empty. Maybe there's something I've missed, so I would appreciate any help. Thanks!
