If you populate the RadChat control using its DataSource and then bind the CurrentAuthor property, the message from the current author don't use the correct color. This reproduces only if the CurrentAuthor binding is set after the DataSource binding.

Note that the title says that this happens when using the DataSource, but you can reproduce it also if simply add a message from an author different than the current one, and then change the CurrentAuthor to the one used for the message.

To resolve this change the order of the property bindings. The first one should be CurrentAuthor and then DataSource.
<telerik:RadChat CurrentAuthor="{Binding MyCurrentAuthor}" DataSource="{Binding MyMessageSource}" />

Regardless of the current culture applied, the date shown on top of a group of message uses InvariantCulture (English). In comparison the time break date is formatted according to the culture.

This comes from a bug in WPF.

To work this around, override the Language property metadata of FrameworkElement.

      new FrameworkPropertyMetadata(

If you host RadDropDownButton in a ScrollViewer and then start scrolling (using mouse wheel) while its dropdown content is opened, the scrolling works and the buttons goes outside of the viewport. However, the dropdown content (Popup) stays within the viewport, which looks like the dropdown gets detached from the control.

To avoid this, handle the scrolling of the ScrollViewer when the dropdown content is opened. This behavior is already implemented in RadComboBox by overriding its OnMouseWheel method and handling the event arguments.

To work this around subscribe to the MouseWheel event of RadDropDownButton and set the Handled property of the event arguments to True.

private void RadDropDownButton_MouseWheel(object sender, MouseWheelEventArgs e)
	var btn = (RadDropDownButton)sender;
	if (btn.IsOpen)
		e.Handled = true;

I need an overview of the appointments in the range of multiple days of several resources (let's say, employees).

For this, the agenda view would be perfect if it shows the days as rows but the grouped resources as columns.

In the current version it as possible to group by resources in the agenda view, but the single resources can be displayed only as rows along with the days. This way an overview is not possible. At now, I have to put several ScheduleView controls side by side, each displaying a single resource, to achieve the desired view.

Therefore I want to engage a feature request:

Please, in the agenda view, allow a grouping of resources with arranging them in a horizontal way, while the days stay arranged in a vertical manner.

Currently the LocalDataSourceProvider has such support and we can consider introducing the same functionality in the QueryableDataProvider.

To reproduce: 

- Select some cells within the same column using Ctrl+Click

- Use the context menu to copy the cells

This works in Excel when the cells are within the same column.

We noticed that RadGridView does not get garbagecollected sometimes.
So i fired up  a memory analyzer to see what is going on.

This is the graph that shows that the RadGridView is causing a leak. The only references that keep the GridView from getting collected are those two WeakEventListeners

To further investigate i decompiled GridViewDataControl and could identify the culprit.

private void SubscribeToDispatcherShutdown()
      if (this.dispatcherShutdownListener != null)
      this.dispatcherShutdownListener = new WeakEventListener<GridViewDataControl, object, EventArgs>(this);
      this.dispatcherShutdownListener.OnEventAction = (Action<GridViewDataControl, object, EventArgs>) ((grid, source, eventArgs) => grid.OnDispatcherShutdownFinished(source, eventArgs));
      this.dispatcherShutdownListener.OnDetachAction = (Action<WeakEventListener<GridViewDataControl, object, EventArgs>>) (weakEventListener => this.Dispatcher.ShutdownFinished -= new EventHandler(this.dispatcherShutdownListener.OnEvent));
      this.Dispatcher.ShutdownFinished += new EventHandler(this.dispatcherShutdownListener.OnEvent);

In the second line from the botton

... weakEventListener => this.Dispatcher.ShutdownFinished -
... you are using 'this.Dispatcher...' which causes the leak since the Action will implicitly capture the 'this' reference.
Which kind of defeats the prupose of having a WeakReference inside your WeakEventListener.

Sadly i cannot figure out how it happens, but i think its only when Detach (FrameworkElement.Unloaded ultimately) is not called.
While this is the actual issue, i thought I'd share this with you so you.
