<p>Anyone know of a good free winforms html editor for .NET. Ideally I would like html and preview modes along with the possibility of exporting to a pdf, word doc or similar. </p>

<p>Although the export I could probably create myself from the html output.</p>

<p>Another nice feature would be a paste from word that removes all the extra tags you usually end up with but again it's a nice to have not a required.</p>

You can use the
WebBrowser
control in design mode with a second
```
WebBrowser
```
control set in view mode.
In order to put the
```
WebBrowser
```
control in design mode, you can use the following code.
This code is a super stripped down version of a WYSIWYG editor for one of our software products.
Simply create a new Form, drop a
```
WebBrowser
```
control on it, and put this in the Form.Load:
```
```
Me.WebBrowser1.Navigate("")
Application.DoEvents()
Me.WebBrowser1.Document.OpenNew(False).Write("<html><body><div id=""editable"">Edit this text</div></body></html>")

'turns off document body editing
For Each el As HtmlElement In Me.WebBrowser1.Document.All
    el.SetAttribute("unselectable", "on")
    el.SetAttribute("contenteditable", "false")
Next

'turns on editable div editing
With Me.WebBrowser1.Document.Body.All("editable")
    .SetAttribute("width", Me.Width & "px")
    .SetAttribute("height", "100%")
    .SetAttribute("contenteditable", "true")
End With

'turns on edit mode
Me.WebBrowser1.ActiveXInstance.Document.DesignMode = "On"
'stops right click->Browse View
Me.WebBrowser1.IsWebBrowserContextMenuEnabled = False
```
```
