How to Use the `U` Tag in RDLC with JavaScript Rich Text Editor?

3 mins read

In RDLC (Report Definition Language Client-side) reports, not all HTML elements and styles are supported. One common issue is the lack of support for using the  tag with text underline styles. This guide provides a solution to replace such unsupported elements with the  tag, which is fully supported, ensuring compatibility in your reports.

Problem Overview

Supported Tags in RDLC

The RDLC format supports the  tag for underlining text:

<u>TEST</u>

Unsupported Tags in RDLC

The  tag with a style=“text-decoration: underline;” is not compatible with RDLC.

<span style="text-decoration: underline;">TEST</span>

Proposed Solution

Replacing  Tags in Rich Text Editor

To solve this issue, we can modify the HTML content within a JavaScript Rich Text Editor by replacing  tags with  tags for underlined text.

By leveraging the actionComplete event of the Rich Text Editor, you can dynamically replace unsupported  tags with  tags.

Step-by-Step Guide:

Initialization of Rich Text Editor:

Set up the Rich Text Editor with the necessary toolbar items and attach the actionComplete event:

var defaultRTE = new ej.richtexteditor.RichTextEditor({
    toolbarSettings: {
        items: [
            'Bold',
            'Italic',
            'Underline',
            '|',
            'NumberFormatList',
            'BulletFormatList',
            '|',
            '|',
            'SourceCode',
            '|',
            'Undo',
            'Redo',
        ],
    },
    actionComplete: actionComplete,
});
defaultRTE.appendTo('#defaultRTE');

Function to Handle actionComplete Event:

Implement the logic to replace  tags:

function actionComplete(args) {
  const editorContent = defaultRTE.element.querySelector('.e-content');
  if (editorContent) {
    const paragraphs = editorContent.querySelectorAll('p');
    paragraphs.forEach((paragraph) => {
      const spans = paragraph.querySelectorAll(
        'span[style="text-decoration: underline;"]'
      );
      spans.forEach((span) => {
        // Create a new <u> element
        const underline = document.createElement('u');
        underline.textContent = span.textContent;
        // Replace the <span> with the <u>
        span.parentNode.replaceChild(underline, span);
      });
    });
  }
}

Conclusion

By following these steps, you can ensure that underlined text is correctly represented in RDLC reports by replacing  tags with  tags in the Rich Text Editor. This solution maintains compatibility and functionality across different document formats.
