Syncfusion Blazor Spreadsheet Editor

Overview

Generates production-ready C# and Razor code for integrating the Syncfusion Blazor Spreadsheet component into Blazor Server or WebAssembly applications. The skill produces copy-pasteable code snippets with Excel-like functionality including cell editing, formatting, formulas, data operations, and worksheet management.

Key Capabilities

• Data & Binding: Load from byte[], local JSON file, remote JSON URL, or Google Drive; save via Ribbon
• Cell & Range Operations: Editing with events, UpdateCell, set formulas, autofill, range actions, merge/unmerge cells, cell formatting, number formats, conditional formatting
• Rows, Columns & Worksheets: Insert/resize rows and columns; insert, delete, move, and duplicate worksheets
• Data Operations: filtering, sorting, hyperlink add/edit/remove, cut/copy/paste, cell and range selection
• UI & Interactivity: Hide/show Formula bar , Hide/show Context Menu, custom data rendered via XlsIO
• Protection & History: Sheet and workbook protection/unprotection, undo/redo operations
• Images: Insert, resize, and move images through UI (enabled by default)
• Chart: Insert and delete charts in the active worksheet programmatically via InsertChartAsync / DeleteChartAsync; configure move, resize, type, theme, legend, data labels, gridlines, and axes through the UI
• Ribbon Customization: Customize the Spreadsheet Ribbon (add/remove/modify ribbon tabs, groups and items)

Quick Start Examples

Example 1: Display a basic spreadsheet

User: "Add a basic Spreadsheet to my Blazor page" Result: C# + Razor code snippet displayed (no files created)

Example 2: Disable filtering and sorting

User: "Create a spreadsheet with filtering and sorting disabled" Result: Basic sample merged with filtering.md and sorting.md snippets

Generate C# Code for the User's Project (default)

Trigger keywords: "how to", "add spreadsheet", "code sample", "show me", "example", "snippet", "integrate", "component", "create sample", "code", "sample code", "generate code", "implement", "add to project", "configure spreadsheet"

Step 1 - Analyze Request & Select Snippets

• Parse the user's intent and identify the requested features.
• Always start with references/basic-sample.md as the base.
• Map each requested feature to its corresponding references/*.md file.
• If no feature keywords match, output only the basic sample.

Step 2 - Consent & Destination Gate (MUST ASK FIRST - STOP HERE UNTIL USER RESPONDS)

Before generating or writing any files, ask the user:

I'm ready to generate your Syncfusion Blazor Spreadsheet sample.

Where should I place it?
1) Create a new Razor file in the skill's "output" folder (recommended for quick tryout)
2) Add/modify an existing file in your project (please provide full path; choose append or replace)
Or, say "Just show me the code" to get the snippet here without changing files.

• Do not proceed until the user explicitly chooses an option or says "Just show me the code."
• If the user declines file changes, only output the code in chat (no files created/modified).

For Option 2 only: Before generating code, check if the project has the prerequisites from references/basic-sample.md (Prerequisites and Setup Requirements section). If missing, ask user consent and add them.

Step 3 - Generate Code (Dry-Run)

Build the code in-memory by merging:

• Base: references/basic-sample.md
• Merge matched feature snippets into its anchors: PROPERTY, EVENTS, BUTTON, API METHOD
• Do not invent or modify any property, event, or API beyond what the reference files contain

Step 4 - Apply Changes (Only After Consent)

Option A - Create new file in skill's folder:

• Create a output/ folder at the skill's root and place the file there
• Default file name: SpreadsheetSample.razor (configurable via user reply)
• If the file already exists, ask:

  A file named "SpreadsheetSample.razor" already exists. Overwrite, append, or use a different name?
  

  Copy
  Stop and wait for the user's decision before proceeding.
• Write the generated Razor/C# content.

Option B - Add to user's project file:

• Ask the user for the full path of the target file and whether to append or replace
• If the path does not exist, ask: I can create this file. Proceed with creation?
• If replacing, make a backup copy (e.g., .bak) before writing (if the environment supports it)
• Apply the change per the user's instruction.

Step 5 - Report Outcome

Done
- Location: {path}
- Action: {created|overwritten|appended}
- Notes: {any warnings or unsupported features}

If file operations were skipped, confirm that the code was only displayed in chat.

Code References

All templates and feature snippets live in references/*.md. Each file is a focused snippet the agent combines when generating samples.

Flow: Always start with references/basic-sample.md, then merge matched feature snippets into its anchors (PROPERTY, EVENTS, BUTTON, API METHOD). If no feature keywords match, return only the basic sample.

Supported Features: Editing, Filtering, Sorting, Cell merging, Insert row/column, Hyperlink, Clipboard actions, Cell formatting, Conditional formatting, Chart, Ribbon customization, open and save, selection

Rules

1. Use Only Reference Snippets

   • Generate code exclusively from the Markdown files under references/
   • Do not invent/guess/include any properties, events, API methods, component names, or parameters not present in references/*.md

2. UI interaction feature

   • The following features support only UI interaction and have no customization options (no methods, events, or properties):
   • Gridlines - Toggle visibility through UI only
   • Images - Image insert, resize and move actions through UI only
   • Do not generate methods, events, or properties for these features
   • Only add these features if they are explicitly mentioned in references/*.md files
   • If a user requests customization for these features, inform them: This feature supports only UI interaction and does not have programmatic customization options in the Blazor Spreadsheet component.

3. Unsupported Feature Handling

   • If the user requests a feature with no corresponding snippet in references/*.md, respond with: That feature is not currently supported by the Syncfusion Blazor Spreadsheet component.
   • Suggest the closest supported features only if they have snippets
   • Explicitly list unsupported items and do not synthesize code for them

4. Validation Before Write

   • Re-validate before writing that all code blocks originate from references/*.md files
   • If validation fails, stop and inform the user

5. Transparency

   • Include a Supported vs. Unsupported summary in the final report when applicable
