*Added: The control's tooltip is shown when the cursor hovers it no matter if the window that hosts the control is activated
*Fixed: The expropertieslist/com fails if the user is trying to spy the control (x64 version only, AllowSpy property, browses the object by drag and drop)
*Fixed: No file is generated by CopyTo method if the file name ends with spaces

17.0.0.2 Aug 05, 2024

17.0.0.1 Jul 10, 2024
*NEW:   Ability to specify the size to show the icons/images/check-boxes/radio-buttons within the control
*Added: ImageSize property specifies the size of control' icons/check-boxes/radio-buttons. By default, the ImageSize property is 16. The control's Images collection is cleared if the ImageSize property is changed, so it is recommended to set the ImageSize property before calling the Images method. The ImageSize property specifies the size to show the icons using the Column.HeaderImage, Items.CellImage or Items.CellImages property, the cell's check-box or radio-button using the Column.Def(exCellHasCheckBox), Column.Def(exCellHasRadioButton), Items.CellHasCheckBox, Items.CellHasRadioButton property, the default-size of <img>number[:width]</img> tags within ex-html captions, unless the width is not specified, the size of expand/collapse glyphs, sorting icon (ascending or descending), drop-down or close filter button. The ImageSize property defines the size (width/height) of the icons within the control's Images collection. For instance, if the ICO file to load includes different types the one closest with the size specified by ImageSize property is loaded by Images method. The ImageSize property does NOT change the height for the control's font(Font), sort-bar (SortBarHeight), header (HeaderHeight), item(DefaultItemHeight) or filter-bar(FilterBarHeight)

*Added: The Background(exTreeLinesColor) method defines the color to show the tree-lines (connecting lines from the parent to the children)
*Fixed: The FilterBarBackColor property does not support EBN objects (The last 7 bits in the high significant byte of the color to indicates the identifier of the skin being used. Use the Add method to add new skins to the control. If you need to remove the skin appearance from a part of the control you need to reset the last 7 bits in the high significant byte of the color being applied to the background's part)
*Fixed: The Background (exToolTipForeColor) property does not apply to the tooltip's title

16.0.0.1 Jul 21, 2023
*NEW: Z-Events support (Standard .NET event patterns)
*Added: Every event of the control (/NET assembly) provides a Z-Event alternative, of "void OnEventRaised(object sender, EventArgs args)" type. The .NET convention is for an event (Z-event) signature to have a void return and 2 parameters. The first parameter is of type System.Object and is the sender of the event. The second parameter must be of type System.EventArgs or derived from System.EventArgs and contains data passed between sender and receiver. For instance, the "DblClick(object sender, short Shift, int X, int Y)" event is equivalent to "ZDblClick(object sender, ZDblClickArgs e)", where "ZDblClickArgs" type is derived from System.EventArgs and includes definitions for Shift, X and Y properties
*Fixed: "Warning: The <event-name> event is a .NET event that does not follow the .NET convention for event signatures (OpenEdge, ABL code)". To prevent this warning, under OpenEdge environment you must use the Z-event alternatives 

15.0.0.2 Mar 13, 2023
*Added: GridLinesStyleEnum.exGridlinesGeometric flag. The control's gridlines are drawn using a geometric pen.

14.0.0.3 Sep 19, 2022
*Added: The expression properties supports `bias` constant that defines the difference, in minutes, between Coordinated Universal Time (UTC) and local time. For example, Middle European Time (MET, GMT+01:00) has a time zone bias of "-60" because it is one hour ahead of UTC. Pacific Standard Time (PST, GMT-08:00) has a time zone bias of "+480" because it is eight hours behind UTC. For instance, date(value - bias/24/60) converts the UTC time to local time, or date(date('now') + bias/24/60) converts the current local time to UTC time
*Fixed: The Column.Def(exHeaderPaddingRight) property causes the pointer-cursor not to be shown while cursor hovers the column's drop-down filter button (Column.DisplayFilterButton property)
*Fixed: On some machines, the format keyword (within expression properties) provides more than 2 decimals for French(Canada) regional settings (for instance "12.3456 format ``" displays 12.3456 instead of 12.35)

*Added: The Images method supports the Microsoft ImageList ( mscomctl.ocx, MSComctlLib.ImageList type) object directly. Shortly, you can define the control's images by calling Images(ImageList1.Object). The ImageList1.Object returns the object of MSComctlLib.ImageList type. The Microsoft ImageList object is available for /COM on x86 and x64 machines (starting from Access 2016)

*Fixed: "Not a valid bookmark.", "Record is deleted." error may be fired, when the control's DataSource property points to an ADODB.Recrodset, whose Requery method has been invoked. When the control is notified that a Requery, Filter has been performed on the control's DataSource, all items are cleared, and new one are inserted by re-iterating the recordset source.

11.0.0.1 Jan 14, 2019
*NEW:   Ability to executes x-script code ( including events ), from a string, file or a safe array of bytes. This feature allows you to load the control's visual appearance and behavior, without having to write any line of code. The x-script code can save EBNs, icons, pictures into BASE64 encoded strings, and so everything can be put into a single file, that should be invoked by AttachTemplate method. This feature allows you to run any x-script code for any configuration of the component (/COM, /NET or /WPF). 
*Added: AttachTemplate method executes the giving x-script code, and attach events if found. The x-script code can contain handle keyword that defines a handler for the specified event. For instance, the AttachTemplate("handle Click() { print(Version) }") sends the control's Version property to the debugger for display. All you need is to open the DebugView tool, and click the control.
*Added: The control's Template page supports AttachTemplate so you can assign x-script code ( including events )  in design mode, and so the control's visual appearance and behavior is changed once the control is created at runtime (/COM version only). 
*Fixed: "The current version, supports ADO and DAO Recordsets. Make sure that the object is an ADO recordset, or a DAO recordset" error may occur if using the ADO objects.

*Added: The Items.CellSingleLine property specifies whether the cell's caption is displayed on single-line, or wraps around the words or line breaks. Previously, the Items.CellSingleLine property was of Boolean type, while currently it is of CellSingleLineEnum type. For instance, Items.CellSingleLine() = exCaptionBreakWrap indicates that the cell's caption is displayed on new lines when line break is found ( <br> for HTML captions or \r\n sequence ). Also, the option is valid if you specify the Column.Def(exCellSingleLine) property.
*Fixed: The Items.SelectableItem property returns 1 instead of -1 / True value.
*Fixed: The Items.SelectItem property returns 1 instead of -1 / True value.

*Added: Shows the drop down filter and tooltip panels to the nearest monitor relative to the cursor position.
*Added: The Background(exColumnsPositionSign) specifies the visual appearance for the position sign between columns, when the user changes the position of the column by drag and drop. By default, the Background(exColumnsPositionSign) property is 0, which indicates that the default position sign is shown when the user change the column's position by drag and drop.
