[BUG] The grid no longer shows sorting-related items in header context menu if sorting is forbidden in the grid.
[BUG] An error when a form containing grid has been modally displayed several times and the grid incorrectly displayed horizontal scroll bar at that time.

.Net Suite, v2.7.0 (Build 2.7.0.46034) [2012-02-20]

Starting from version 2.7.0 grid functionality has been expanded with reporting and printing features. Programmers get simple and convenient interface for implementing new features and can significantly expand capabilities of target applications.

Reporting features:

Software control of reporting with full customization support.
Possibility of adding any images or text to printed pages.
Page spanning: If there are too many fields to fit on one page, the fields can span two or more pages.
Repeating headers: to improve document readability the grid can insert headers to every printed page.

shared among all grids. Instead, it uses an individual instance of this
dispatcher that allows programmer to create grids in different message
loops.
[ENH] Added a Grid(IDispatcher) constructor enabling to specify an arbitrary model of cross thread synchronization.

The following bugs have been fixed:

[BUG]

[ENH] Column.Sortable
behavior has been changed. This property no longer blocks column
programmatic sorting, however it prevents user from sorting columns by
clicking a header.

[ENH] Significantly improved sorting speed by columns, when cells have identical or similar values.
[ENH] Added MeasureCellWidthEventArgs event for adjusting column width for custom-drawn content.

The following bugs have been fixed:

.Net Suite, v2.5.0 (Build 2.5.0.40128) [2011-06-13]

Data editing

[ENH] .Net Grid now supports data validation,
where the programmer may specify whether user value is valid and pick
one of the possible actions - cancel editing results, apply new value,
ask user to enter a new value, display an error icon or switch to
editing a new cell.
[ENH] Navigation between editors by pressing Enter, Tab, Shift+Tab has been added.

Data binding

[ENH] Grid interaction with data sources has been completely refactored.
As the result, the grid can now work in thread-safe mode with
different data sources including IList, IBindingList, IListSource
and with BindingSource and CurrencyManager.
[ENH] Ability to bind any row to data sources via
Row.DataSource
property has been added.
[ENH] It is now possible to bind .Net Grid to
multiple data sources
simultaneously via IListSource interface (e.g. to multiple IBindingList at the same time).
[ENH] Data binding can now be combined with Grid.Rows.Add() / Row.Add() methods.
[ENH] Ability to build a hierarchy when data objects in one or several properties return collections of other objects has been added.
[ENH] It is now possible to create a hierarchy with multiple IBindingList containing objects of different types.
[ENH]
It is now possible to subscribe to IBindingList events and to objects
in IBindingList collections if they implement INotifyPropertyChanged
interface. Their thread-safe processing, sorting, filtering, grouping
and painting are maintained.
[ENH] Conditional binding feature
has been added. With this feature the grid asks how the data
should be added. For example, if a data object contains a collection
of other objects, the programmer can add its collection instead of the
object itself, thus missing a whole hierarchy level while hierarchical binding.

Drag & drop

[ENH] A feature of dragging data
within a grid and between grids has been added.
[ENH]
It is now possible to move data on the same hierarchy level and to
perform hierarchical dragging of rows while preserving state and
hierarchy of dragged objects.
[ENH] Full customization of drag
& drop process supporting choice of content and various effects,
place of insertion and hierarchy is now available.
[ENH]
Features for dragging and dropping data to external applications (Excel,
Word.) and importing data from external applications providing an
interface to deserialize data and insertion methods have been added.
[ENH] Intuitive automated scrolling where needed during data dragging has been added.

Lasso selection

[ENH] The grid now supports a new method of
user-friendly data selection.
When the user moves the mouse with left button pressed,
the grid displays a semi-transparent area, and all rows within
this area become selected. Various effects are supported when Ctrl or Shift keys are pressed

Other new features of the grid

[ENH]
A new Header.StretchMode property enables stretch widths of all the
columns so that they evenly occupy the available space.
[ENH] Column configurator has been changed.
[ENH] The design mode has been completely revamped. Now it is much more programmer-friendly and makes its work much simpler.
[ENH] Grid.RowExpanding event has been added.
[ENH] It is now possible to adjust the height of the group panel.
[ENH] Memory consumption while binding to data sources has been reduced and performance has been increased.
[ENH] Memory consumption has been reduced by 20% for operations with simple data including objects of arbitrary classes.
[ENH] +70 new data binding tests

Enhancements:

[ENH] Added row grouping in the Grid.
[ENH] Grouping features for data populated from IBindingList, IListSource, IList, etc...
[ENH] Added binary and XML serialization.

[ENH] Added support for asynchronous and synchronous synchronization when notifications from INotifyPropertyChanged interface arrive from non-GUI thread. Settings are available through the Grid.Threadsafety property.
[ENH] Added support for the TypeConverter in properties. If a property of a data object has a TypeConverter, declared with the TypeConverterAttribute,
then the .Net Grid uses this converter to format values to strings and
to parse text into these values (it the converter supports conversion
from strings). More about data formatting.
[ENH] Significantly improved row removal rate and performance of the entire Grid.
[ENH] By default the Grid navigates to the first Row in the hierarchy when a user presses Key Left and to the last row when he presses Key Right.

[BUG] Fixed the bug related to the calculation of optimal cell height with text wrapping and padding enabled.
[BUG] Editors can remain visible even the grid is hidden behind other window.
[BUG] Calculation of optimal column width is incorrect, if the column is sorted.
[BUG] IDE designer can raise InvalidOperation exception when a column is added to .Net Grid.

but also by placing the cursor between the two cells. This enables user
to resize columns, if the header is not visible.

ability to change row height, not only via row separators, but also by
placing the cursor between the two cells. This enables user to resize
rows, if the row selector is not visible.

places at any hierarchical level. For example you can dock any UITypeEditor rows that act as filters or a row that calculates an average value for the column.
[ENH]
If a user clicks on another cell after editing, the grid automatically
goes into edit mode of the new cell. Users no longer have to click
multiple times on the new cell to start editing.

[ENH] Added Grid.FilterRefresh() method to re-check all rows for filtering. Usually it is called when filter conditions in IFilter interface change.
[ENH]
Added very nice and useful feature - pop-up tooltips in cells. NetGrid
provides a very simple API for implementing this ability. By default,
all cells that have pop-up tooltip have a red exclamation mark to the
right of the cell's value that makes such cells immediately
identifiable. Using this feature a programmer can mark some cells and
provide explanation text in pop-up balloons.

The following bugs have been fixed:

[BUG] Fading effect is not correctly displayed when the Cell.Highlight() is called with an interval different than Grid.Highlighting.Interval
[BUG] It is possible to add objects, implementing IList or IDictionary
[BUG] Hot frame indicating an editable cell may remain visible after the cursor leaves this cell
[BUG] Sorting a column with identical strings is extremely slow
[BUG] Changing Appearance in the Grid.PaintRow event does not take effect

.Net Grid, v2.0.2 (Build 2.0.2.19337) [2010-05-03]
