If you have the following model, the columns that show the Test and Date properties (in the derived class) cannot be sorted or filtered.

 

public class RowModel
{
    public int Id { get; set; }
    public Bar FredBar { get; set; }
}
 
public class Fred : Bar
{
    public DateTime Date { get; set; }
    public string Test { get; set; }
}
 
public abstract class Bar
{
    public string Title { get; set; }
    public double Value { get; set; }       
}

<telerik:RadGridView.Columns>
    <telerik:GridViewDataColumn DataMemberBinding="{Binding Id}" />               
    <telerik:GridViewDataColumn DataMemberBinding="{Binding FredBar.Title}" />
    <telerik:GridViewDataColumn DataMemberBinding="{Binding FredBar.Value}" />
    <telerik:GridViewDataColumn DataMemberBinding="{Binding FredBar.Date}" />
    <telerik:GridViewDataColumn DataMemberBinding="{Binding FredBar.Test}" />
</telerik:RadGridView.Columns>

To work this around, set the IsCustomSorting property of the corresponding columns and implement a custom sorting in the Sorting event of RadGridView.

Bind a grid to a DataView

Start editing and change the values of a few cells.

Press Escape twice to cancel the edit of the entire row.

Expected: the values return to the old values

Actual: the values remain the last entered ones

When we make frozen column width bigger than the window will hide other columns. Scrolling is applied only to not frozen columns. So we can't scroll to see other columns.

A possible workaround is to set MaxWidth property of the column.

Release LIB 2019.2.826 (08/26/2019)
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 invalid rows that were loaded but not in viewport get valid, the invalid state (row validation indicator) is still visible.

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.

Loading items in RadGridView takes too much time due to operations executed on the UI.

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.

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.

Release R2 2019 SP1
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.
