特性

BulletChart

• Bullet Chart is the variation of bar chart, which displays one or more measures, and compares it to a target value. You can also display the measures in a qualitative range of performance such as poor, satisfactory, or good.

Chart

• Background for chart - Set backgrounds for chart and chart area.
• Smart axis labels in polar and radar charts - Hide the labels that overlap one another in polar and radar charts.
• Axis label trim in polar and radar - Trim the polar and radar axes labels when they exceed the chart area.
• Trendline collapse - Collapse the visibility of a trendline using its legend.
• Polar and radar data label improvement - Place data labels in polar and radar charts at different positions like top, bottom, middle, and outer.

Word Library

• Mathematical equations - Word Library now allows creating and editing mathematical equations (MathML) in Word documents (DOCX and WordML).
• Autofit table content - Word Library now automatically adjusts table cell size based on its content.

Word Processor

• Comments - Enables users to add and edit comments in a Word document.
• Server-side SFDT conversion - Allows server-side conversion of SFDT (Syncfusion Document Text) to DOCX, RTF, etc., formats.

File Manager

• File Transfer Protocol (FTP) file system provider support - Provides support for a File Transfer Protocol service provider that helps manage files in the File Manager control.

Gantt Chart

• Row drag and drop - Provided support to drag and drop rows to reorder rows dynamically within the Gantt control.

Grid

• Frozen rows and columns with row virtualization - The row virtualization feature allows you to load data instantly as you scroll vertically and render rows in a frozen grid based on the viewport height. This helps improve the frozen grid performance when loading large data sets.
• Frozen rows and columns with column virtualization - The column virtualization feature allows you to render columns based on the current viewport width in a frozen grid. The rest of the columns will render instantly as you scroll horizontally. This helps improve the frozen grid performance while providing a large number of columns.

Heatmap Chart

• Legend title customization - Provided support to customize legend titles in the heatmap control.

Maps

• Zoom the maps based on markers - Zoom the maps initially, based on the marker’s location.
• Marker clustering improvements - Cluster and expand markers with the same latitude and longitude values.
• Initial/dynamic selection and deselection - Select or deselect the shapes dynamically and on initial rendering.
• Binding colors and shapes to markers - Bind colors and shapes to the markers from the data source.

PDF Library

• PDF/A conformance - Support provided to create PDF/A conformance documents. Using this library, the following types of conformance documents can be created.
• Validate the incrementally saved PDF digital signatures - Improved the PDF digital signature validation algorithm to identify Incremental saving attacks (ISA).
• Remove duplicate resources when merging PDF documents - Support provided to remove duplicate PDF resources such as image and fonts when merging PDF documents.
• Create Long Term Validation (LTV) when signing PDF documents externally - This feature allows you to digitally sign a PDF document externally with LTV.
• Create ZUGFeRD 2.0 PDF document - Support provided to create ZUGFeRD 2.0 PDF documents.

PDF Viewer

• Handwritten signature - This feature allows users to include handwritten signatures in PDF files and provides options to customize and remove signatures.

Pivot Table

• Conditional expression support when creating calculated field - In addition to the existing formula creation, users can now provide a conditional expression. For example, the conditional expression “Sum(Sold) !== 0 ? Sum(Amount)/Sum(Sold)” : 0 can be given in both code-behind and calculated field UI.
• Performance optimization during virtualization - During virtualization, the performance of the pivot table improves based on the uniqueness of the raw data fields. With the new data compression technique, the pivot table can now be connected to 1 million raw data aggregated to 1,000 unique data and rendered within 3 seconds rather than 10 seconds.

Rich Text Editor

• Code format feature improvements - Keeps a single pre tag in the selection’s parent nodes instead of creating individual pre tags. The Enter key is handled by merging the newly created pre tag to the previous one.
• Code format as toolbar button - Allows users to configure code format as a separate toolbar button with a toggle state to apply and remove code formatting.
• XHTML validation support - Allows users to validate the source content of the Rich Text Editor against the XHTML standard. When you enter or modify content in the editor, it continuously checks the XHTML source content and removes elements and attributes that are not valid.

Scheduler

• minDate and maxDate support - minDate and maxDate support is provided to restrict date navigation and event rendering in the Scheduler.

Spreadsheet

• Filtering - When filtering, if values in one or more columns do not meet the filtering criteria, the entire data will be hidden. You can filter texts, dates, and numbers.
• Undo and redo - This feature provides an option to undo and redo changes made in a workbook. You can customize the limit of undo and redo operations.
• Hyperlink - This feature allows users to navigate to web links or cell reference within the sheet or other sheets in the Spreadsheet.
• Collaborative editing - This feature allows multiple users to work on a spreadsheet at the same time and view the changes made by others instantly.

TreeGrid

• Autofill - The autofill feature allows users to fill adjacent cells with the currently selected cell value using a drag-and-fill action similar to Microsoft Excel behavior.

Excel Library

• Macros - A macro is a set of programming codes that runs in the Excel environment to automate tasks. XlsIO allows you to create and edit macros in Excel worksheets using IVbaProject and save the worksheets in different formats such as XLS, XLTM, and XLSM.
• Conditional formatting enhancement - Conditional formatting now allows you to highlight the following:
  • Top or bottom ranked values.
  • Values that are above or below average.
