Disabling ConvertFontToSpan Filter to avoid the span to font conversion in Design mode

Environment

Property	Value
Product	RadEditor for ASP.NET AJAX
Version	all

Description

When utilizing the ConvertFontToSpan filter in RadEditor for ASP.NET AJAX, the <span> tags in the HTML content are automatically converted to <font> tags in the Design mode of the control. This behavior is due to the built-in browser commands preferring the use of <font> tags over <span> tags. However, if you want to retain the <span> tags in the HTML section without any conversion you can disable the ConvertFontToSpan filter.

Solution

To avoid the conversion of <span> tags to <font> tags in RadEditor for ASP.NET AJAX, you can disable the ConvertFontToSpan filter. Follow these steps:

1. In the code-behind file (e.g., Page_Load event), add the following code:

csharp

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        RadEditor1.DisableFilter(EditorFilters.ConvertFontToSpan);
    }
}

VB

Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
    If Not IsPostBack Then
        RadEditor1.DisableFilter(EditorFilters.ConvertFontToSpan)
    End If
End Sub

2. Save the changes and test your code to verify that the ConvertFontToSpan filter is disabled and the <span> tags are preserved in the HTML section.

By disabling the ConvertFontToSpan filter, you can ensure that the <span> tags are not automatically converted to <font> tags in RadEditor for ASP.NET AJAX.
