將對凍結窗格的支援添加到您的試算表允許使用者在記住關鍵參考點的同時滾動流覽大量資料。

Freeze pane support allows you to fix specific rows or columns in place while scrolling through the rest of the data. This is particularly useful for large spreadsheets with header rows or key columns you need to reference constantly. By freezing panes, you ensure these crucial elements remain visible even as you navigate across vast datasets, improving readability and data analysis efficiency.

Several WinForms spreadsheet controls offer freeze pane support including:

  • DevExpress WinForms Spreadsheet (part of DevExpress WinForms) provides you with the ability to fix headers and key columns for seamless navigation in massive datasets.
  • Aspose.Cells for .NET allows you to lock specific rows and columns in place while scrolling, improving spreadsheet readability and navigation.
  • Syncfusion WinForms Spreadsheet (part of Syncfusion Essential Studio Enterprise) allows you to freeze rows or columns for effortless scrolling within complex spreadsheets.
  • Telerik WinForms Spreadsheet (part of Telerik UI for WinForms) enables you to pin headers and columns for intuitive navigation and improved data comprehension.

用浮水印提高 PDF 安全性和品牌

在 PDF 文件上加蓋文字或圖像浮水印，以防止抄襲並加強您的品牌形象。

PDF watermarking is the process of embedding a semi-transparent text or image overlay onto a PDF document. This visual identifier, often used for copyright protection or branding, sits behind the main content, subtly preventing unauthorized copying or modification while still allowing the document's message to be conveyed. Watermarks can be applied to all pages or specific ranges, offering versatility for various use cases.

Several .NET PDF viewer components allow you to add watermarks to a PDF, including:

  • Telerik UI PDF for WPF (part of Telerik UI for WPF) offers robust PDF manipulation capabilities for WPF applications, including watermarking.
  • Syncfusion Xamarin PDF (part of Syncfusion Essential Studio Enterprise) lets developers embed custom watermarks in PDFs, ensuring document authenticity across platforms.
  • Document Solutions for PDF by MESCIUS provides tools for adding watermarks to PDFs, supporting document protection and identity reinforcement in .NET environments.
