Remember, it's Not Just a Grid Control! The ExpressQuantumGrid Suite includes the best grid control in the business - so good in fact, in a review by Delphi Informant Magazine it was said of the QuantumGrid, "After my experience with ExpressQuantumGrid and ExpressInspector... I can't imagine developing a Delphi database application without these tools. The grid is the most capable VCL grid I've found. Just by using a small part of its capabilities and customization options, my applications seem more professional, and the users enjoy the editing capabilities." But... The Suite is far more than this powerful grid control... the suite is also comprised of over 70 standalone field editors and individual controls - many available in data-aware and non data-aware editions.

Whats New in v2011 vol 1Know n Issues and Important Changes List

This topic provides a brief overview of the new features introduced in the ExpressQuantumGrid Suite . Click a link below to jump to the corresponding section. Layout View New Chart View options Locked View Image New 'Group By' Panel Layout Grid navigator enhancements Multi-line editor autosizing Alternate hints for column headers Data export enhancements Performance enhancements Filtering enhancements Persistence enhancements Layout View In Layout View, data records are displayed as cards.

This View extends the Card View, in that it gives end-users an ability to visually remodel card structure using drag-and-drop operations. In customization mode, end-users can manually rearrange card rows within cards in the following ways:l

l l l

Combine card rows into layout groups. These groups in turn can be nested within other groups, allowing a layout hierarchy of any level. Children contained in a group can be tabbed, organized vertically (one under another) or horizontally (across the group). Span card rows over neighboring rows and layout groups. Add auxiliary layout elements (empty regions, separators and labels) to the card from the Customization Form. Temporally hide unnecessary card rows and layout elements in the Customization Form, or even delete layout elements created at runtime which will not be further used Page during application session. 2 the of 3856

New Chart View Options These include enhanced Chart Views, and new Chart View options.l

Chart diagrams now provide the following features:l l l

Missing data representation. Missing values can be shown as either empty points or zero values. Transparency support for filled diagrams (requires the Microsoft GDI+ Library). Antialiasing. For a better-looking chart display, there is an option to apply smoothing (requires the Microsoft GDI+ Library).

Locked View Image For time-consuming operations, such as bulk data updates, the grid can optionally display a "Locked View" image informing endusers that the View is awaiting updates.

Page 9 of 3856

As illustrated in the screenshot above, a "Locked View" can be displayed with dark and light visual effects. New 'Group By' Panel Layout The "Group By" panel provides two options to display dropped column headers. The first uses a standard layout, in which headers are shown hierarchically. In the new layout, column headers are aligned horizontally, taking up less space vertically.

Grid navigator enhancements The grid navigator is equipped with an "Info Panel" section. This panel displays information about the total number of records and the focused record's position.

Page 10 of 3856

You can change output format along with text font, and handle mouse click events using the navigator's API. Multi-line editor autosizing New sizing options for our multi-line editor include:l

In-place editor sizing. In the edited data cell, an editor is sized vertically to fit the entered content. When the end-user has finished editing, the height of the containing row is automatically changed to fit the new data.

l

Row sizing. The entire row being edited is dynamically sized when wrapping to the next line within the editor.

l

Single-line scrollable text input. You can opt to disable sizing for all items or just for certain items.

Auto sizing is not supported by the drop-down editors, non-text editors, and input mask text editors. Alternate hints for column headers As an alternative to the default hint, you can provide any explanatory text specific to the column in the hint window. This hint can be displayed even if the column caption is not clipped.

Data export enhancements The grid now supports exporting to the XLSX format (Microsoft Excel 2007 and higher). If you are using the new export routine, the image format in the final output is the same as it is defined in the grid.Page 11 of 3856

Performance enhancements In a multi-level View, data processing has been significantly improved. The following table provides a performance comparison of v2011.1 and v6: Demo load time, ms v2011.1 468 v6 3760

The performance was measured in MasterDetailMultiDemo, which is shipped with the product. Filtering enhancementsl

l

The Filter Rows incremental filtering mode has been extended with the deferred update option. If the option is enabled, the View is updated after a specified delay. It allows an end-user to make a more complete entry within the Filter Row before applying the entered filter string. For a large amount of data, update pending can be reduced, since the number of filter requests are less than when the data is processed with each keystroke. Filtering performance for a large amount of data has been significantly improved.

Persistence enhancements Complete grid layout persistence in MDI applications via View aliasing.

Known Issues and Important Changes ListWhat's New

All entries in the following list are grouped by Builds, in reverse order. Build v2012vol 1.1 Previously, the view navigator was partially displayed if you used large icons in navigator buttons. Now, the navigator takes into account their dimensions, and positions them appropriately, so that they are fully displayed. Build v2011 vol 2.2 In the Layout View, alignment settings (the Horizontal Alignment and Vertical Alignment menu items) have been removed from the root layout group's context menu. Now, if the Layout View is in a display mode other than lvvmSingleRecord, the group's alignment settings are always set to top-left. In lvvmSingleRecord display mode, the alignment settings are set to occupy the entire client (View), and these can be adjusted via the new OptionsView.SingleRecordStretch option. Breaking Change The scxGridDeletingConfirmationCaption resource string has been removed because cxMessageDlg, which used this resource string, was replaced with the standard VCL MessageDlg. Build v2011 vol 1.3 Breaking Change:l l

Previously, the hint was displayed on-screen for an indefinite time. Now, the hint display time interval is limited, by default. Now, the hint is suppressed on the mouse down, by default.

Build v2011 vol 1.2 Breaking Change The EcxGridExport type is no longer used in exception handling. Errors are now handled using a standard Delphi exception mechanism. Build 54 1. Breaking Change The TcxCustomGridTableView.OptionsView.Navigator property has been removed. Use the TcxCustomGridTableView.Navigator.Visible property instead. 2. Breaking Change Now, the TcxCustomGridTableView.NavigatorButtons property is not available in the Object Inspector. Use the TcxCustomGridTableView.Navigator.Buttons property instead. Build 48 Breaking Change A typo has been fixed in the TcxCustomGridOperationHelper.PerformStarndardOperation method. Now it s called TcxCustomGridOperationHelper.PerformStandardOperation. Build 39 Now, if the VisibleForCustomization property of a grid item (column or card row), band, or chart item is set to False , this item or band cannot be removed by end-users from a View via the drag and drop, Quick Columns/Bands Customization dropdown, or context menu. Build 38 The parameter list has been changed in the TcxCustomGridTableController.FindNextItem, TcxCustomGridTableController.FocusNextItem and TcxCustomGridTableController.FocusNextCell methods and in the corresponding overrides of the TcxCustomGridTableControllers descendants. Build 36 Previously, the Views built-in data navigator only posted records being inserted or appended when these records were modified. This limitation has now been removed. Build 20Page 13 of 3856

All entries in the following list are grouped by Views. Common Changes Table Views and Banded Table Views Banded Table Views Card Views Chart Views Common Changes 1. Package files, package source files, and resource files have been renamed as follows:l l

cxGridVCLC6/D6/D7 -> cxGridC6/D6/D7 dclcxGridVCLC6/D6/D7 -> dclcxGridC6/D6/D7.

2. Report Link for the ExpressQuantumGrid. The name of the Report Link's unit now includes the version number of the ExpressQuantumGrid to prevent code changes when migrating to a new major version of the ExpressQuantumGrid. This means that you should use the following units:l

dxPScxGrid4Lnk for ExpressQuantumGrid v4 dxPScxGridLnk for ExpressQuantumGrid v5 (we have decided to leave it "as is" because v5 is the current version of the Grid as of the release date) dxPScxGrid6Lnk for ExpressQuantumGrid v6.

l

l

3. In TcxCustomGridRecord:l l

The DoKeyPress and KeyPress methods have been removed. The KeyDown method and the IsParentRecordLast, IsValid and LastParentRecordCount properties are now protected.

ABCDEFGHIRSV Grid control The main difference between versions 3 and 4 of the ExpressQuantumGrid is that the latter is capable of displaying data within multipl ExpressQuantumGrid4 provides different Views (Table, Banded Table and Card Views) for displaying data while ExpressQuantumGri Table View (which can be displayed with or without bands). Most of the TdxDBGrid functionality is now implemented by View objects. V data fields by means of "items". An Item represents a column in Table Views and a row in Card Views. Refer to the Views and Items se A data controller represented by the Views DataController property implements data-aware operations such as loading data, filtering, summaries. Customizing colors and fonts has been delegated to Style objects and so is implemented now by assigning styles to grid e These changes mean that the multitude of top level properties in the grid have been replaced by a small collection of objects. While the more efficient and extensible product, we recognize that users of ExpressQuantumGrid3 will have initial difficulty in finding the properti event handlers for ExpressQuantumGrid4 and hence the reason for this topic. Note: the two technologies are very different so there isnt always a simple replacement available.

Grid control The main difference between versions 3 and 4 of the ExpressQuantumGrid is that the latter is capable of displaying data within multiple Views. ExpressQuantumGrid4 provides different Views (Table, Banded Table and Card Views) for displaying data while ExpressQuantumGrid3 provides just one basic Table View (which can be displayed with or without bands). Most of the TdxDBGrid functionality is now implemented by View objects. Views present data from data fields by means of "items". An Item represents a column in Table Views and a row in Card Views. Refer to the Views and Items sections for more details. A data controller represented by the Views DataController property implements data-aware operations such as loading data, filtering, grouping and calculating summaries. Customizing colors and fonts has been delegated to Style objects and so is implemented now by assigning styles to grid elements. These changes mean that the multitude of top level properties in the grid have been replaced by a small collection of objects. While these changes provide for a more efficient and extensible product, we recognize that users of ExpressQuantumGrid3 will have initial difficulty in finding the properties required while converting event handlers for ExpressQuantumGrid4 and hence the reason for this topic. Note: the two technologies are very different so there isnt always a simple replacement available. While we have tried to cover as many options as possible, the following lists can never be totally complete (you may be using our product in ways we havent considered!). If you still have difficulty in replacing your ExpressQuantumGrid3 code because your needs are not covered here, please write to [email protected] and we will help you.
