DataContext of rows is sometimes null when UI virtualization is enabled in the Flat group render mode.

The issue appears also without UI virtualization and in the Nested mode. It happens on ItemsSource reset of RadGridView, in case the old ItemsSource value wasn't empty. The DataContext is set to null for a brief moment before the old visuals are removed from the view, which causes issues in some scenarios related to CellTemplate

If the DisplayIndex of the columns is set when they are initialized, ColumnGroups are not displayed.

As a workaround, you can set the DisplayIndex after the columns are initialized. 

 

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

When the HorizontalContentAlignment of the GridViewCheckBoxColumn's CellStyle setting to Center, the checkboxes in the columns remain on the left side. If another theme like OfficeBlack is used, the checkboxes go on the center.

The GridViewSelectColumn is a very nice and useful feature, especially the possibility to select all items with just one click on the header. It would be great if there was the same functionality for the group header. So clicking on a checkbox in group header will select all items in this group (only). I know there are some examples (many years old) of how to do this, but it would be much better if it worked out-of-the-box.

When the RadGridView is bound to a collection of DynamicObject and runtime we add a new property to the objects, this new property will not be respected. The columns will not be refresh.

At this moment, the Search As You Type functionality can be customized. We can expose several methods so that the user can override the default search behavior and implement their own.

Add support for binding to properties of type GUID.

Implicit row's style should be not cleared when the SelectStyle method of RowStyleSelector returns null.

Setting the IsVisible property of a column, which is frozen on the right size by setting the RightFrozenColumnCount property, does not work as intended. 

When using INotifyDataErrorInfo, items are still validated even when the ValidationType property is None.

 

Please note that when the AutoGeneratedColumns property is set to true, the item's HasErrors property will be evaluated, but only once.

 

 

This happens in the following scenarios:

1. The FilterMemberPath points to the Date property of a DateTime one.
2. The column name contains "[]" square brackets.

Provide a way to change the ItemsSource of the control while it is exporting using SpreadStreamExport.RunExportAsync() method
