The example below demonstrates how to clean the content in the content area from a standard input button:

```ASP.NET
<telerik:radeditor runat="server" ID="RadEditor1">
   <Content>
	   Here is sample content!
   </Content>
</telerik:radeditor>
<input type="button" value="reset" onclick="ResetContent();return false;" />
<script type="text/javascript">
	function ResetContent() {
		var editor = $find("<%=RadEditor1.ClientID%>"); //get a reference to RadEditor client object
		editor.set_html(""); //reset the content
	}
</script> 
```

> caption Avoid calling set_html() in Preview Mode, because the content is no longer editable in this mode and tampering with it can cause errors. Here's how to make sure you avoid that:

```ASP.NET
<script>
	function setNewContent() {
		var editor = $find("<%=RadEditor1.ClientID%>");
		if (editor.get_mode() < 4) { //1 and 2 are Design and HTML modes respectively
			editor.set_html("new content " + new Date());
		}
	}
</script>
<asp:Button Text="set content" OnClientClick="setNewContent(); return false;" runat="server" />
<telerik:RadEditor runat="server" ID="RadEditor1" RenderMode="Lightweight">
	<Content>
	lorem ipsum
	</Content>
</telerik:RadEditor>
```
