Fix available in R2 2018 SP1 version.

The copyright notice is shown on top of the content. It cannot be moved and there is no way for the customer to see the content beneath the notice.

     if the pie chart area's size is auto,when adjust the area's  vertical size,the pie's radius  will change in order to fit the label display,it is ok,but when adjust the area's horizontal size,the pie's radius don't  change,looking the attachment file,the label move above the pie.

I would like to do a Backstage design without writing code, the syntax of XAML is confusing and I do not understand it well, besides being slow, the development of software at design time is always much faster.

Short version of feature request: 
It would be nice to be able to enforce unique value in a column in an MVVM environment?

Long version of request:
To enforce a unique value in a column I ended up with a custom ValidationAttribute in the data model. Very much like the last example in the old thread 
https://www.telerik.com/forums/force-validation-on-new-record-insert

Direct link to the example provided by Telerik:

At a first glance, the solution seems to work, but if you edit a value in a cell and the new value is the same as another cell in the same column, BOTH these cells would have an error. Not just the cell you edited. I understand that not all cells can be validated whenever a single cell is edited, but it would nice if there was way to configure the RadGridView to “refresh” validations of all visible cells when a validation error is either set or removed?

I do not know if a solution like this would fit the internal design of the RadGridView, but it might give you some inspiration :-)

Add an attribute to the column definitions in the GridView:
ValidationTransitionMode= Default | ForceValidationOfAllVisibleCellsInColumn | ForceValidationOfAllVisibleCells

Default: 
No change from existing functionality.

ForceValidationOfAllVisibleCellsInColumn: 
Whenever a validation result of a cell changes (from no_error to error OR from error to no_error) all the visible cells in the column will be re-validated. This would do the trick to enforce uniqness in a column with a custom ValidationAttribute.

ForceValidationOfAllVisibleCells: 
Whenever a validation result of a cell changes (from no_error to error OR from error to no_error) all the visible cells of the complete grid will be re-validated. To be used by people with more complex validation algorithms depending on values in other columns as well.


Steps to visualize the current problem.
◦Run the example (https://www.telerik.com/clientsfiles/375715_328546-TestApp-new.zip )
◦When the application is running, reduce the window height (from the bottom) so that the scroll bar is visible and the top visible row shows “last name”=”Rockhead 0” and the bottom visible row shows “Rockhead 4”.
◦Change last name “Smith 3” to “Smith 1”.
◦Now there is a red border around the cell we edited (as expected) but nothing happens to row 2 (First name=Jane1).
◦Scroll to the bottom and back up to the top.
◦Now there is also an error on row 2 (First name = Jane1).
◦Change “Smith 1” back to “Smith 3” (on the row where First name=Jane 3).
◦The error on the cell edited is now removed, BUT the error on row 2 (Jane 1) is still visible even as all values in the Last name column is now unique.

I got some very good support and a suggestion to modify the control template, but it would still be nice to be able to control the validation execution of cells, other than the current cell.

Telerik.Windows.Controls.SpreadsheetUI.for.Wpf NuGet package is not uploaded on the Telerik NuGet server.

Fix available in LIB Version 2018.3.1029.

I'm using the fluent theme in my app. When I load ColorVariation.Dark, everything is dark except a sub-window. This is a window created by my main window. Its main control is TabControl with most of the tabs items being ListBoxes using data templates. The Listboxes display dark but the window itself is light along with the first tab item which is just a grid with TextBoxes. I don't specify background color on any of these controls so I assumed they would come from the theme. Do I have to do something to pass the info th a sub-window?

An exception is thrown when the ItemsSource of the ItemsSourceProvider is bound to a DataTable and an item is select in the drop-down.

The fix for this issue will be available with our next official version – R1 2019 expected in the middle of January. 

I have downloaded the SDKSampleBrowser application from link but when I open application I am getting error attached in log file.

 

When we load an XML file to the diagram using DiagramRibbon the ribbon does not clear the diagram items

Scheduled for:
The fix for this issue will be available with LIB (version 2019.1.128) scheduled for publishing on Monday, 28th January 2019.

Setting StyleManager.Theme attached property is not respected by RadDiagramToolBox.

Two tabs are required to navigate between property fields in the following themes:
- Office2013
- VisualStudio2013
- Green
- Office2016(Touch)
- Material
- Fluent
- Crystal

Steps to reproduce

1. Click somewhere in the document to move the cursor
   • The cursor starts blinking in the exact location is was moved to after you clicked
     
2. Move the cursor with the arrow keys on the keyboard
   • The first time the cursor blinks it moves slightly to the right of the position it was moved to by the arrow key
     

Unfortunately due to the other cursor jumping bug our users are extremely sensitive to anything that makes it appear like the cursor is not in the position they moved it to.

I attached a gif of this happening with the zoom set to 500% so it is easiest to see but it appears to be a problem at any zoom level 100% or higher.

Select file/fodler. Press F2 and rename it. Click Enter. File stays selected but pressing F2 does not enter edit mode again.

Currently, the  StringToGlyphConverter is not available with the .NET Core version of the Telerik dlls. Introduce the converter in the .NET Core project.

Currently the RadWatermark TextBox does not support RadSpellCheck. We are requesting that spellcheck support be added to this control

Hi Team,

 

We have a business case, where we build a spreadsheet with collapsable groups and subgroups. Our customers wanted to have an overview about the group totals on each group and expand and collapse the groups on demand (because it's also possible in Excel).

 

So, it would be awesome, if you could extend your spreadsheet component with that feature as well.

 

Thank you

when open the RadRibbonBackstage by click the ApplicationButton ,if click some one area which is not  the above ApplicationButton,
then the RadRibbonBackstage  is closed,the ApplicationButton's fluent mouseover effect don't disappear
