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.

Implement a way to group columns cells vertically.

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

As of R1 2018 RadGridView supports pinning columns both on its left and right side. The new properties that control the right-side behavior are: RightFrozenColumnCount and RightFrozenColumnsSplitterVisibility.

Fix Section 508 Compliance accessibility errors. 

Our requirement is to navigate through RadGridView table header using keyboard tab navigation.

The header may or may not include checkbox/filter button.

However on mouse focus on table headers , it get highlighted. This feature is currently not possible with tab navigation.

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.

Introduce property to set the text of the GridViewNewRow element responsible for adding new rows to the control.

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?
