The evaluation of invalid expressions in RadGridView should not crash the host application.

For example when you set 11, the year should change to 2011. Currently it concatenates the new digits to the previous year and then it removes the first two digits.

1) Use nested scrollbars
2) When the first row in the child template is not visible, I've scrolled down to the end of the list.

Steps to recreate this scenario:
Create an interface e.g. IBaseInterface with couple of properties.
Create another interface e.g. IChildInterface which implements the first one
Create a class which implements the second interface.
Create a list with items of type the child interface.
Fill the list with objects of type the class.
THE PROBLEM IS VALID ONLY FOR 2.0 NET FRAMEWORK!
FIXED TO WORK WITH ALL VERSIONS UNCLUDING TREEVIEW!
When a control is bound to this list it will only "see" the properties defined in the child interface.

1. Create a new project with RadGridView
2. Create and add a column which uses editor based on RadMultiColumnComboBox
3. Run the project and try to filter by this column

There is an exception when the new row is current and clicking on a column header. Steps to reproduce:

1. click to add a row but don't make a selection
2. click on the row header

Create GridViewRowInfo's EnsureVisible method overload that expands all parent rows and ensures visibility of the row.

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
