If the autohiding feature of the taskbar is enabled and RadWindow is maximized, the taskbar is not displayed when the mouse is over the bottom of the screen.

This is observed also in RadTabbedWindow.

If the DataSource property is set before the MessageConverter property an ArgumentException is thrown.  The error message is "Item cannot be converted to MessageBase".

To work this around, make sure that the MessageConverter property is set (and evaluated) before DataSource.

We distribute two types of themes solutions with our source code. The first one are: Themes.Sources.sln (for Silverlight), Themes.Sources_WPF.sln and Themes.Sources_NetCore.sln which are used to rebuild our themes. The second one are those without Source in their names, which are used to distribute the output files. Adding references there will remove the errors which appear.

As a Followup to this (Bad performance with grouping)Forumpost I managed to reproduce the issue now.
Since i cannot upload zip-files in the Forum I am doing it here.


The problem is, that a single grouping dramatically increases the time for sorting the values.
When the grouping is not present, sorting the same column is much faster.


It appears that it is related to the ammount of columns in total (not grouped).
The ammount of records is not so important, 100 (as in the attached sample) should not be significant.

The check mark of the RadioButton is misaligned when DPI settings are set to a higher than the default value, e.g. 125%.

The problem can easily be reproduced using the Telerik UI for WPF Demo application:

It appears the ChartView is also affected by the same SharpDX issue that affected the RadWebCam when it is used over Remote Desktop. 

A simple test of any series will replicate the issue. If it is being used via Remote Desktop, the series will not render.

Allow setting OriginValue on the series in the RadPolarChart. Currently, the area series are fixed to OriginValue of 0.

The same feature is available in the RadCartesianChart series.

This behavior is reproducible when the ItemHeight and ItemWidth properties are changed runtime. When thеse properties are changing, and an item is removed, its container is still presenting in the UI, which leads to an empty container.

Implement functionality to rotate the text in a cell.

I'm using a "Custom Heat Map Source" as described here:
https://docs.telerik.com/devtools/wpf/controls/radheatmap/howto/create-custom-heatmap-source

Upon initialization, I fill in the color of all the cells with a default color.
Later, as data comes in, I update the color of individual cells.

It seems that the only way to refresh the Definition so that it will display the newly set cell color is to do the following:

HeatMapDefinition.SelectedItems = new Collection<object>();

After that, the Definition updates itself by calling method "CustomHeatMapDefinition::GetColor()" on each and every cell (which of course gets delegated to the "CustomHeatMapSource" implementation.

This could lead to performance problems on large Heat-Maps.

So my request is that there is a feature allowing the updating of individual cell-data and a refresh mechanism that would not query each heat-map cell afterwards, but only the updated cells.

I have discussed this in a support request (https://www.telerik.com/account/support-tickets/view-ticket/1464531) with Dinko and he suggested I request this feature.

Best,
Mark
