TopGrid V2.20.8  release notes  August26th, 2001

The following are the list of enhancements, defects fixed, and known problems on the given release date...
General Fixes.
1. Determined that Delphi 6 no longer considers Bookmark = EmptyBookmark to be a valid comparison. This comparison

6. Add clNone as a valid color to all color properties
7. Added ability to set Alignment, ControlType and ButtonType for multiple selected columns
8. Added ability to delete multiple selected columns
9. Fixed issue with column moving in editor where selected column was not showing correct column properties

2. No column headings on report if HeadingOn = False

The following are the list of enhancements, defects fixed and known problems for 2.20 (beta 2)...

1. New properties on grids called PrintOrientation, PrintLinesPerPage and PrintTotals

2. New property on TtsCol called PrintTotals to specify if a grand total should be shown on the grid report for that column. PrintTotals property must be set to true for any column totals to appear.

3. New property on grids called ProvideGridMenu (True/False). Setting to true will automatically configure a popup menu (if none defined) that contains three menu options Print Preview..., Print..., and Export.... The Print Preview will bring up the grid report preview window. The Print will print the grid report to the default printer immediately. The Export will display a save dialog to save as either CSV or XML. HTML must be done programmatically using the TtsHTMLGridProducer component.
* Note: If a PopupMenu is already associated with the grid, then setting the ProvideGridMenu to True will show the menu options at the bottom of the existing popup menu with a line separator.

4. Improved Combo editing to the Design Editor with a new easy to use interface - list of combos for just the combos used on the grid (no need to scroll the grid horizontally anymore). Easier property setting and field specifications for the columns of the dropdown.
* Note: StoredData entry is not available yet.

5. Fixed defect where adjusting the columns of a multi column combo did not take.

6. Fixed defect where LookupDatasource data was not being populated in the combo data grid.

7 New property grouping called Data within the grid property viewer to view just the data oriented properties of a TtsDbGrid.

8. New BeginUpdate / EndUpdate methods on grid to disable and re-enable grid painting when performing mass changes to the data. These are just more well known method calls to encase the already existing EnablePaint property .

9. Fixed defect where it was no longer possible to reference a column in the grid by the field name.

10. Fixed defect associated with Delphi 6 not being forgiving (like Delphi 5) on the AnsiCompareStr function. Was periodically causing an AV error when selecting the combo or during keyed entry.
