This happens after setting in property builder the RadGridViews', DataSource (containing more than one table).

In the add new row element there is some cells€™ values, which are set through code (programmatically). 
However, if there is not at least one cell, which was manually edited (changed its value), the row cannot be committed.

In some cases Columns Group View has impropriate cells layout, mostly rendering two borders on one and the same side for some particular cells.

AutoSizeRows is not currently supported.

If there is an underling font in the grid, exported file cannot be opened from MS Excel.

When using textbox and grid bound to the same datasource, the grid should be updated automatically when the textbox loses focus

When using column groups view the last row is partially visible.

If there is conditional formatting it takes wrong settings for base cell colour.

RadGridView should be able to filter by enum values.

If in underling datasource there are more than one field, which do not allow null values, trying to set them in DefaultValueNeeded event leads to exception "Column [columnName] does not allow nulls"

Sort capabilities in column chooser form.

RadGridView remains in edit mode if the focus has been taken from RadToolStrip's item (for example: ButtonElement is clicked)
It is an issue in the obsolete RadToolStrip. Works as expected with RadCommandBar.

Set AutoSizeRows and WrapText to true.
Start resizing the form.
You will see that the cell size is wrong.

When constructing hierarchy with many nested levels (more that 2) at design time, the serialization fails.

If you change AutoSizeRows property's value from true to false, RadGridView's layout is not changed accordingly

Custom filtering for Enum types, TypeConverter support for business object bind to RadGridView

The issue appears when there are two open child views.

When adding a new row with Enter key the RowValidating event fires as expected. However, you can not cancel the event.

Add error provider for AddNewRow element and options to show validation error icon and text.
