FluentPalette's ScrollBarMode provides the ability to customize ScrollBar appearance in the Fluent theme. Its default value is Auto and can be set to Normal or Compact depending on the desired constant ScrollBar size.

The property is available with LIB version 2019.1.0121 released on Monday, January 21.

The designer throws an error when the default style of a control which has a RadSplitButton/RadDropDownButton in its control template is extracted in a ResourceDictionary and then merged in App.xaml. There must be a custom style which is based on the extracted one to reproduce the error. This behavior is only present in 2019 R3.

The error is "This feature requires service 'Microsoft.Windows.Design.Services.ValueTranslationService' to be present, but it could not be located."

If the DataMemberBinding of a GridViewMultiColumnComboBoxColumn points to a nested property, the value of that property is displayed in view mode and the DisplayMemberPath is not respected.

If ExportDefaultStyles is set to true, the default styles are exported. If the user has set some settings in the ElementExportingToDocument handler, those are ignored.

Setting the property to false allows the custom setting to be applied, but the default ones are gone

When adding a new row and we click inside a DropDownContent of a DropDown control, the RadGridView loses focus. This way RowValidating event is called which is not expected.

After a cell is edited, a tooltip set through a style trigger is not shown.

In Office2016 when we increase the DPI of the Windows a left border in the header of column disappears. As a workaround you can set the Width property of all columns.

This happens only if there are many columns outside of the viewport (a scrollviewer is shown), with their TabStopMode property set to Skip.

In this case, the navigation needs some time in order to get to the next row and select the first available cell.

A possible workaround for this would be to implement a custom Keyboard Command Provider, and to replace the MoveNext command with a custom one, that moves the current cell, by setting the CurrentCellInfo property of RadGridView.

When adding a new row (before committing it) and we switch between the cells the RowValidating event is called every time.

The fix for this issue is available with LIB (version 2018.3.1126) published on Monday, November 26.

 

Currently the string is localized as "Filtre" and it should be localized as "Filtrer".

My requirement is to give certain rows in the GridView a background color that is read from the database (so it's not a fixed list of colors). I use the RowStyle with a binding to the Background property. When the bound property is null, I fall back on the Transparent color.

This transparent background in combination with a GridViewComboBoxColumn sometimes causes rows to "stick" to the top or bottom of the grid. To simulate this, a ComboBox in the grid must be opened, then you need to scroll up or down until the field is outside the viewport. In some cases, the row sticks to the top or the bottom. After inspecting the Visual Tree, it appears that the row is still part of the Visual Tree, even though it is outside the viewport. I have attached a video and a sample project where you can see and test this behavior.

Sample:
<telerik:RadGridView ShowSearchPanel="true" ShowSearchPanelCloseButton="false"
or
<telerik:RadGridView ShowSearchPanel="true" ShowSearchPanelCloseButton="Hidden"
