This bug is related to the text shown on top of the message groups. The text shows the time + the author's name. For example: "12:30PM,John Doe". 

Add a space between the time and the author's name. It should be "12:30PM, John Doe", instead of "12:30PM,John Doe".

To work this around, add a space before the author's name when you create the Author instance.

this.Chat.AddMessage(new TextMessage(new Author(" John Doe"), "Hi", DateTime.Now.AddDays(-3)));

Or extract the ControlTemplate of MessageGroup and add a Margin to the TextBlock element that shows the Author's name.

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(

SearchStateManager property is null when trying to change any of the properties of the SearchStateManager object in the Loaded event. This behavior is observed when the ShowSearchPanel property is not set to true initially.

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;

It would be great to be able to tag an author with @.

The idea is to provide an authors list like in skype :

The authors list could be setted with binding from ViewModel by example. Message could have a tagged authors list too in order to easily send a notification to all tagged users from ViewModel.

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

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.
