## Telerik UI for Blazor — Validator

### When to Run

**CRITICAL: Run the validator after every code generation step that involves Telerik components.**

- After generating or modifying any `.razor` file that contains Telerik components
- After applying changes suggested by the component assistant
- Before considering any implementation task complete

### Calling the Validator

Use the `telerik_validator_assistant` MCP tool. Provide the **absolute path** to the Razor file to validate.

**Tool call:**
```
telerik_validator_assistant({
    filePath="<absolute path to the .razor file>"
})
```

**Example:**
```
telerik_validator_assistant({
    filePath="C:/MyProject/Components/Pages/Dashboard.razor"
})
```

### Interpreting Results

- **No errors reported** → the file passes validation. Proceed.
- **Errors reported** → fix ALL reported errors before proceeding.
  - For each invalid property, use `telerik_component_assistant` to find the correct parameter name or type.
  - Re-run the validator after fixing to confirm all issues are resolved.

### What the Validator Checks

- Invalid or non-existent component parameters
- Incorrect parameter types or values
- Misconfigured component syntax
- Icon name validity

### Validation Loop

```
1. Generate or modify Razor code with Telerik components
2. Call telerik_validator_assistant with the file path
3. If errors found:
   a. Call telerik_component_assistant to find correct members
   b. Fix all reported errors
   c. Return to step 2
4. Proceed only when validator reports no errors
