Enable clients to set custom HelpText for the controls from the suite.

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

Hello Telerik,

I started working with the RadMultiColumnComboBox.
A feature that I miss is opening the combo on focus.

The RadComboBox has OpenDropDownOnFocus and I use it very often.

Thanks in advance

Simplified and Traditional please

We have customers in Brasil and Polish. It would be very helpful, if Telerik would support these languages out of the box. Otherwise we have to adapt our product whenever we are upgrading to a new Telerik version.

Add localization support for Polish language

Please, provide official Russian Localization for, at least, WPF products. This is the only question, why customers chose other providers than Telerik. For example, I like Telerik WPF controls more, but me head at work bought other WPF-vendor because they provided official Russian Localization. Thanks.

During the XAML export, by default images are serialized to XAML using the Convert.ToBase64String(byte[]) method. 

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?

This is similar to AutoCompleteBox. However, you can write text freely and the suggestions popup should appear only when you enter a special character like '@' for example. This behavior is observed in the facebook, slack and ms teams chats. You can mention someone in the chat.

With the release of the Fluent theme, it would be nice to have a Hamburger Menu control similar to the NavigationView for UWP (https://docs.microsoft.com/en-us/windows/uwp/design/controls-and-patterns/navigationview).

NavigationView is available with our latest official version - R1 2019.

.Net Core 3.0 (https://github.com/dotnet/core/blob/master/roadmap.md) is now activly developed. It will support WPF on Windows. How are your plans to support it?

Any roadmap?

Introduce a property to close the dropdown upon selection (when in Single mode).


*** CloseDropDownAfterSelectionInput property will be available with Q1 2019 expected in the middle of January. When set to True, the dropdown will be closed only with SelectionMode Single. 

Would be useful for setting timezone offsets and for more control to the user

Currently, the DefaultVisualStyleSelector doesn't kick-in when the Direct2D or the Bitmap render options are used and their DefaultVisualRenderMode property is set to Batch.

Note that DefaultVisualRenderMode=Separate works.

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.

In the current version of the WPF SDK Sample Browser Application it is really hard to track what's new and what control was updated. Even the version of Sample Browser by itself (2018.3) is not visible.

Maybe you remember the former Sivlerlight Online Demos (I'm not sure if it is still around but I cannot run it anymore because it needs IE11)? There was always an updated or new badge on the controls. So it was obvious what was new and updated.

I think this should be possible in WPF also.

When hovering with the mouse over the control panels there shoud be more information shown like date of the last update of the sample.

When clicking on a control on viewing the samples of the control, I can only open the folder, open in VS or run it. Sometimes it makes sense to open directly the sample on github to quickly check the version history.
