保留與 MHT 共用的報表格式

4月 19, 2024
將 .NET 8 WPF 報表導出為廣泛相容的 MHTML 格式，從而保持佈局保真度並啟用離線查看。

MHT (MHTML or MIME HTML) is a web archive format that bundles a web page's HTML code and all its resources such as images, stylesheets, and scripts into a single file that can be viewed offline or in applications that don't require an internet connection. Exporting to MHT format gives you a single archive file that contains your webpage and all its necessary components. This format is especially beneficial for preserving the exact state of a web page at a specific point in time, allowing for offline storage and easy sharing without losing the original design and functionality. Additionally, it simplifies the management and transfer of web content by consolidating multiple files into a single entity.

Several .NET 8 WPF reporting components allow you to export to MHT, including:

  • ActiveReports.NET by MESCIUS enables .NET 8 WPF applications to export complex reports to MHT for easy archival and offline viewing.
  • List & Label Enterprise Reporting Edition by combit facilitates the distribution of single-file MHT archives, and can be used with WPF applications in .NET 8.
  • Stimulsoft Reports.Wpf is a .NET 8 reporting component that offers MHT export capabilities for easy report distribution through a web browser.

讓網格使用者輸入非拉丁字元

4月 17, 2024
支援輸入法編輯器（IME）的網格控制項允許使用者生成其輸入裝置上本機不可用的字元。

An Input Method Editor (IME) facilitates the entry of complex characters and scripts not directly supported by standard keyboards, which is especially vital for languages with extensive character sets like Chinese, Japanese, and Korean. When integrated into a grid component, an IME enables users to input text directly into data cells using phonetic or syllabic methods that are converted into the desired characters. This integration streamlines the data entry process in applications requiring multi-language support, significantly enhancing usability and efficiency. It simplifies the development of applications targeting global markets by providing native language input support, thereby improving the user experience and reducing the need for external language input tools.

Several WinForms grid components offer Input Method Editor (IME) support, including:

  • DevExpress WinForms Data Grid (part of DevExpress WinForms) includes an IME which is enabled when an end-user switches the desktop key input to a supported language.
  • FlexGrid for WinForms (part of ComponentOne Studio WinForms by MESCIUS) offers built-in IME support, facilitating efficient entry of complex characters in diverse languages.
  • Telerik UI for WinForms GridView (part of Telerik UI for WinForms) integrates IME capabilities, enabling straightforward input of extensive multilingual character sets.
  • Infragistics WinDataGrid (part of Infragistics Ultimate UI for Windows Forms) also boasts input method editor support for effortless text input in globalized WinForms applications.
