She'll walk through how to add an Excel XLSX viewer to a WPF app using the WPF spreadsheet control, Spread.NET for WPF. You'll learn how to load a .xlsx file, lock down the worksheet, and allow users to edit only specific cells — perfect for budget forms, reports, or review-only sheets. Once you have created a WPF project, the steps are as follows:

  • Define the User Interface for the WPF Spreadsheet app
  • Import Excel (.xlsx) Files into the WPF App Excel Viewer
  • Protect the .NET Worksheet in the WPF Excel Viewer

Detailed sample code is included and you can even download a sample project to follow along.

React Gridsでリッチデータ編集を有効化

4月 8, 2025
グリッドコントロールの高度な編集機能と検証機能により、表形式インターフェイス内でのユーザー操作とデータの精度がどのように向上するかを見る

Data interaction and manipulation features in grid components enable users to engage directly with tabular data—supporting not just the display of information, but also its editing, validation, and contextual input. These capabilities are critical for creating rich, form-like experiences within data grids, particularly in applications where user input and data integrity are central to the workflow. By offering a range of editing modes and validation tools, grid components help ensure that data remains both accessible and accurate, enabling intuitive and efficient user interactions.

Common grid editing and validation features include:

  • Custom Editing provides the flexibility to integrate specialized input controls like dropdowns, calendars, or sliders tailored to the data type.
  • Data Validation applies rules to user input, checking for correct formats or value ranges before accepting changes.
  • Editing/Inline Editing allows users to update cell content directly within the grid without navigating away.
  • Input Method Editor (IME) support enables users to input complex characters and symbols that are not available on a standard keyboard.
  • Popup Editor opens an overlay or modal window for more complex data input scenarios, useful when editing multiple fields or larger content.
  • Read-only Columns enforce data integrity by preventing modifications to specific fields.
  • Required Columns ensure that essential data fields are completed before submission, supporting robust data collection.
