Environment

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:

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

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

1. 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.
