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.

When the new value is selected from the GridViewMultiColumnComboBoxColumn, the event arguments in the CellEditEnded event does not contain the new value. 

The GridViewMultiColumnComboBoxColumn of RadGridView allows you to enter the edit mode of the corresponding cells even when the IsReadOnly or IsReadOnlyBinding properties of the column are set to True. 

This is also reproducible when RadGridView.IsReadOnly property is set to True

This is reproducible only when the SelectionMode is set to Multiple.

When loading the columns from a file the columns are read in the order they are found in the Columns collection of RadGridView upon saving them.
Setting the DisplayIndex triggers the internal grid logic that ensures the DisplayIndex of each column is correct. 
The combination of the above two operations can cause the grid to invalidate the DisplayIndex of columns while deserializing them and thus setting invalid values.
To ensure correct behaviour when deserializing sort the columns by their display order property before returning them in ProvideValue()

This is reproduced when the RadGridView is bound to a ListCollectionView and it is grouped. In such a case, when an item is edited, it is brought to the bottom of the group.

When navigating through the cells with the left/right arrow keys, when the last column is reached normally the focus stays on that cell. However, when there are invisible columns on the left/right of the last visible one, the focus moves away from the grid.

As a workaround you can handle the PreviewKeyDown event of the RadGridView when the CurrentColumn is the last visible one.

When the ItemsSource of the RadGridView is reset, disctinct values remain checked in the Filtering Popup. 

For a workaround, check the attached project. 

When the bound to the RadGridView objects implement the IDataErrorInfo interface and an invalid cell is scrolled out of the viewport, the corresponding row becomes valid.

Columns are not automatically generated when binding to an empty table passed by RadEntityFrameworkDataSource

In multiple selection mode, the GridViewMutiColumnComboBox column does not respect its DisplayMemberPath property.

Users reported that the Text Search feature is misbehaving for certain columns in their grid.

We found that that if we take the Telerik example “DeferredSearching_WPF.sln", and change the "int" field+property to "long" , text search for a number indeed falls over.

Can you reproduce this?

The following exception is observed in certain cases:

at Telerik.Windows.Controls.GridView.GridViewVirtualizingPanel.FlatLayoutStrategy.RealizeMergedCells(Double frozenOffset, IEnumerable`1 mergedCells)

at Telerik.Windows.Controls.GridView.GridViewVirtualizingPanel.FlatLayoutStrategy.CalculateMergedCells(Boolean shouldInvalidateMeasure)

at Telerik.Windows.Controls.GridView.GridViewVirtualizingPanel.CalculateMergedCells(Boolean shouldInvalidateMeasure)

at Telerik.Windows.Controls.GridView.GridViewCellsPanel.ArrangeOverride(Size finalSize)

 

Nested property definitions are visible in situations when they don't match the filtering criteria.

If your data contains uint, long or any numeric type different than Int32 or Decimal, the searching doesn't work.
