Font Sizes

You can repopulate the Font Size dropdown with the sizes from 1 to 7 (these are the browser supported values). You can set the FontSizes collection declaratively, programmatically and using the ToolsFile.

Adding to FontSizes Collection Declaratively

ASP.NET
<telerik:RadEditor RenderMode="Lightweight" runat="server" ID="RadEditor1">
	<FontSizes>
		<telerik:EditorFontSize Value="1" />
		<telerik:EditorFontSize Value="3" />
		<telerik:EditorFontSize Value="5" />
	</FontSizes>
</telerik:RadEditor>

Adding to FontSizes Collection Programmatically

Use the FontSizes collection Add() method to include new FontSizes in the list.

C#
RadEditor1.FontSizes.Add("1");
RadEditor1.FontSizes.Add("3");
RadEditor1.FontSizes.Add("5");

Using ToolsFile.xml

You can also populate the FontSizes dropdown using the ToolsFile, as shown in the example below:

XML
<root>  
	<tools name="MainToolbar" enabled="true">    
		<tool name="FontSize" />  
	</tools>  
	<fontSizes>    
		<item>1</item>    
		<item>3</item>    
		<item>5</item>  
	</fontSizes>
</root>

If you want to apply font sizes in pixels (px) or in points (pt) then use the Real Font Size dropdown.
