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.
I would like the fluent theme to support spacing option like it does fonts. The Mail app added a new setting "Folder and message spacing" in which you can pick spacious , medium, or compact. I would like the fluent theme to support something similar. The fluent theme was defined for "finger" access but we still have desktop apps that want dense information with mouse access. I would normally just pick a different theme but because of Windows 10, I can't. Windows 10 no longer supports specifying a default font and WPF no longer defaults to the OS font. This means that all my Windows apps must support picking a font. So I'm stuck with the fluent theme. But I don't always want the "spacious" spacing that the theme uses.
Would it be possible to support picking "spacious", "medium" or "compact" spacing?
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: https://www.telerik.com/clientsfiles/375715_328546-TestApp-new.zip 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.

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.
Please add a feature for justifying the bar series chart so that bar data points can be plotted with a "Left", "Right", or "Center" justification to chart ticks. An image to describe a "Right" vs "Center" bar justification is provided.
In addition to the fast document generation, the SpreadStreamProcessing can be adapted to import documents significantly faster than SpreadProcessing.

looking the attach file,when resize the second gridview's column moving back and forth when at first run the sample,the after columns flicker and the width grow and lessen.and when resize the third column,the 'unit price' column will become the min width. but when test the microsoft's datagrid,it is good,the any other column width's change is gentle.
with windows10/2k DPI/14 inch screen ,when show the gridview gridline,the line is different. the other things,when the tabitem is selected,the dropdownmenu can't mark the selected item. look the attach files!
I know the Transitioncontrol have the MotionBlurredZoomTransition, the effect is better for image ,but not UI content,especially when the UI use the simple color,the MotionBlurredZoomTransition effect is weak,I find the RadCalendar control with the cool zoom animation,How to realize? the other question:How to realize the book turning animation with the Transitioncontrol ?
CartesianCustomLineAnnotation should allow for rendering options (2D, Bitmap, default) to allow for a consistent visual appearance.
When new product features are released it would be useful to show a short introduction for users. View introjs.com to see a similar solution for web development
Add a property to the RadWindow, to enable a behavior, so that when the user attempts to focus on the parent window (while the modal is open), the modal window will flash. You can see this behavior in other Windows applications that show modal dialogs.
Currently if a column is bound to a field of type DateTimeOffSet it is not displayed using the culture like DateTime is. It would be nice if this is supported in the future
Allow to define ChartGrid for axis, not for chart. Every Axis can draw our grid lines. Chart.Grid can be a wrapper for Chart.Horizontal and Chart.Vertical axes. marc.
