When New row is at the bottom and it is current and you try to submit a new record, the events RowValidating and CurrentRowChanged are not fired.

CellValidating and RowValidating events should fire always when closing an editor.

While scrolling down a grid with HTMLView settings, the rows shrink in both height and width towards the upper left corrner of the grid.

If the first column in a flat grid is a GridViewDateTimeColumn and you try to edit it by pressing '1' key without any mouse interaction, you get InvalidCastException.

If there is not VerticalScrollbar in RadGridView, pressing PageUp/Down keys leads to unexpected behavior. To reproduce the issue just place a RadGridView in a Form and add a couple rows, but not enough to vertical scrollbar apear. Run the project and test repeated PageDown and PageUp key presses.

When you set the DecimalPlaces property of GridViewDecimalColumn, this setting is not reflected on the GridSpinEditor

When there is an HtmlView defined, and ComboBox column, the ComboBox element is out of the bounds of the grid's cell.

If you want to cancel CurrentRowChanging (e.Cancel=true), when you click on next row's check box column, it throws the event twice and the next rows' check box has been improperly checked.

The invisible columns are not shown in Column Chooser Form, when the form is shown before data binding with its data source.

When a user enters some data in a cell, then clicks in an empty part of RadGridView and finally clicks a button that calls the Update on the table adapter, no changes are committed to the DB. 
However, this case should be covered and there should be changes in the DataSet

The editor should not cover the table header or scrollbars when the cell is partially visible.

If there are DateTime values less than "1900-01-01", the exported file cannot be opened from MS Excel because it does not support them. 

To Do: a warning for invalid excel values before exporting.

When AutoSizeRows = true and there is column with multiline text values, when hiding that column - shrink row height accordingly.

related to RadGridView AutoSizeRows property and layout logic for row height

If you have two (or more) child views in RadGridView and one of them has horizontal scrollbar and greater height (more rows), when switching to it from a smaller one, the scrollbar overlaps latest row.

When user types in non-numeric input into filter cell, exception is thrown. Expected behavior would be that grid just ignores such a value.

When update certain record of underling DataTable, the RadGridView makes this record as CurrentRow. This leads to unwanted scroll and select of this row.
Comment: Set the SelectLastAddedRow property of the GridViewTemplate to false.

If there are AutoSizeRows = true and TextBox column with Multiline=true then puting the column in edit mode is impossible. 

Please note that this worked with Q2 2009 SP1, but there are two glitches:
- in the first edit, the grid's row loses its heigh
- In edit mode if arrow up key is used to navigate inside the text when cursor is in second row, next arrow up press brings the cursor to upper cell instead to the first row of the text.

When MessageBox is used in CellValidating event and during editing the RadGridView loses focus (for example click on button outside the grid), the event has been thrown twise.

The last text line is cut off
