The signatures are stored in the database as a string, representing the point data of all the lines in the signature.
For example, something like 

"1,2;3,4;5,6;7,8/10,11;12,13;14,15/21,22;23,24;25,26"

when setting Telerik PlatformDark and PlatformLight themes, the DataPager_PageSizesView_LabelText  localization string of the DataPager does not apply. 

Workaround: Use the Telerik themes

For the distinct values, there is a bool property that allows you to hide the distinct values: ShowDistinctValuesFilter. 

Expose similar way for the Show Rows with Values options

when rendering thousands of data, provide fast line chart. This type of series can be used for system performance monitoring or with chart than need to display thousands data points.

WinForms has fast line chart: https://docs.telerik.com/devtools/winforms/controls/chartview/series-types/fastline 

When setting GroupAggregatesAlignment NextToHeader and the column size mode is stretch or auto, the aggregates text in the group header is misaligned, part of the text enters in next column when data changes.

when the column is resized or datagrid is scrolled, the aggregates are aligned as expected

Currently the only buttons which can be navigated to and are interactable using keyboard are the next and back buttons, i.e.:

However, the user is unable to navigate to the 'month' selector or the individual dates:

In addition, if we were to click on the Month label, we also can't navigate or select the month we desire using the keyboard.

When the cells are measured a NullReferenceException is thrown:
