Legal document workflow
Explore Legal Line Numbering
Use stable margin references in a protected legal document, then inspect the editable form fields that remain available to the document recipient.
Line-numbered document
The prepared template keeps every reference synchronized with the page layout.

Line numbers are visual references for review and court filings; they are not characters in the document text.

What this demonstrates
Line references and protected input can coexist
Legal line numbering gives reviewers stable references for contracts, depositions, pleadings, and court filings. The same document can be protected while selected TextFormField objects remain available for data entry.

How it works
The line numbers are stored with the prepared document layout, so they remain aligned when TX Text Control paginates the legal template. They are visual references rather than text characters and therefore do not change the document's selection indices.
The editor starts with EditMode.ReadOnly | EditMode.UsePassword. This protects the surrounding legal language while allowing the template's editable form fields to accept input. TXTextControl.formFields enumerates those fields without unlocking the document.
When the caret enters a field, textFieldEntered supplies its bounds and FormFieldCollection.getItem returns the live field object. The demo reads getStart, getLength, and getText, then repositions the contextual toolbar whenever the text view scrolls or zooms.
TXTextControl.addEventListener("textFieldEntered", event => {
TXTextControl.formFields.getItem(field => {
field.getStart(start => {
field.getLength(length => showRange(start, length));
});
});
});
@Html.TXTextControl().TextControl(settings => {
settings.Dock = DockStyle.Fill;
settings.EditMode = EditMode.ReadOnly | EditMode.UsePassword;
}).LoadText(templatePath, StreamType.InternalUnicodeFormat).Render()
