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. https://stackoverflow.com/questions/520115/stringformat-localization-issues-in-wpf/520334#520334

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

FrameworkElement.LanguageProperty.OverrideMetadata(
      typeof(FrameworkElement),
      new FrameworkPropertyMetadata(
          XmlLanguage.GetLanguage(CultureInfo.CurrentCulture.IetfLanguageTag)));

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;
	}            
}

Release LIB 2020.1.120 (1/20/2020)

Hello,

 

I've found a new bug regarding per-monitor DPI awareness in the latest WPF controls build (2020.1.115).

Applications start fine on the modern Windows 10 systems (1607 or later) but crash on previous Windows versions.

The conditions to reproduce:

  • The application is launched on Windows version older than Windows 10 1607/Windows Server 2016. I've reproduced it on Windows 8.1/Windows Server 2012 R2, but I suppose it also affects Windows 10 1507/1511, and probably Windows 8/Windows Server 2012.
  • Application manifest contains:
<dpiAware xmlns="http://schemas.microsoft.com/SMI/2005/WindowsSettings">true/PM</dpiAware>

Here is the stack trace:

System.EntryPointNotFoundException: Unable to find an entry point named 'GetDpiForSystem' in DLL 'User32.dll'.

   at Telerik.Windows.Controls.InternalWindow.Standard.NativeMethods.GetDpiForSystem()

   at Telerik.Windows.Controls.InternalWindow.Standard.DpiHelper.GetSystemScaleFactor()

   at Telerik.Windows.Controls.InternalWindow.Standard.DpiHelper.CalculateScaleFactor(IntPtr hwnd)

   at Telerik.Windows.Controls.InternalWindow.Standard.DpiHelper.GetPerMonitorDPIAwareScaleFactor(IntPtr hwnd)

   at System.Windows.Window.OnSourceInitialized(EventArgs e)

   at System.Windows.Window.CreateSourceWindow(Boolean duringShow)

   at System.Windows.Window.CreateSourceWindowDuringShow()

   at System.Windows.Window.SafeCreateWindowDuringShow()

   at System.Windows.Window.Show()

   at Telerik.Windows.Controls.InternalWindow.WindowWithNoChromeWindowHost.Open(Boolean isModal)

   at Telerik.Windows.Controls.WindowBase.ShowWindow(Boolean isModal)

   at TelerikWpfCrash.App.OnStartup(StartupEventArgs e) in C:\Users\fedarovich\source\repos\Test\TelerikWpfCrash\TelerikWpfCrash\App.xaml.cs:line 20


The issue happens because the code calls the WinAPI functions not available on these OS versions (for example, GetDpiForSystem, but maybe there are more). 

I've attached a small example to reproduce this issue. It is for .Net Core 3.1, but the same issue exists in .Net Framework too.

The document styles are not respected because of wrongly imported custom style name after copy-paste from MS Word and exported to HTML.

Workaround: avoid using styles with braces in their name.
