When there is a read only column and the user navigates with the keyboard the filter cell in the filter row is skipped.

If you have a cell with value "some date 12:00:00" (12:00:00PM), and you filter the column with:
- Equals "same date 00:00:00" (12:00:00 AM) it shows the PM result (even though the time is different)
- Greater - does not show the PM result and it should

When use radGridView with grouped columns and first columns are also pinned, radGridView.TableElement.ScrollToColumn(i) method does not behave properly. See attached example project.

1. Create a new project with RadGridView
2. Bind the grid to a data source containing 200k rows
3. Allow the multiple row selection (MultiSelect = true)
4. Run the application
5. Select all rows (Ctrl+A)
6. Scroll down
7.Try to select another row

The selected cells are not cleared when already selected cell is clicked.

The scenarion is valid for EF ToBindingList functionality.

When you define a data source which contains display value for null value, the display value does not appear in the column's cells.

ADD. RadGridView - add kitetic scrolling support

If you show a hidden form that hosts a RadGridView control instance, the filtering does not perform correctly.

After updating a cell, the RowsChanged event fires 3 times

1. Add a RadGridView
2. Create a new method and call it on a button click
2. Create and set a ColumnGroupsViewDefinition
3. Add rows in unbound mode

Currently the editor cannot be closed using the CancelEdit method when handling the CellValidating event.

FIX. RadGridView - setting the grid to ReadOnly and then back to normal mode, does not show the AddNewRow

FIX. RadGridView - header cells incorrect state when column grouping is used. The clicked cells remain Hovered even when the mouse is not longer above the cell.

FIX. RadGridView - composite filters does not work

The GetLookUpValue method of GridViewComboBoxColumn throws exception when the column shows enum values.

FIX. RadGridView - FilterButton for Excel-Like filtering of GridViewComboBoxColumn, shows incorrect ToolTipText

ADD. RadGridView - add new column type, where each cell has a drop down which displays a calculator (GridViewCalculatorColumn)

Group Descriptors are added before adding rows in unbound mode and not using defer refresh or Begin/EndUpdate

1. Create a new project and add RadGridView
2. Bind to a large DataSource (e.g. 150 k rows)
3. Set MultiSelect property to true
4. On a button click call the SelectAll method
5. Run the application and click the button
