Hi,
If you are building a custom feature you can easily add an html editor. The best thing to do is look at the code for existing features that use one and copy the needed parts.
ie this would go in the .aspx page or in a .ascx:
<mpe:EditorControl id="edContent" runat="server"></mpe:EditorControl>
and in code behind you would have something like this:
protected override void OnPreInit(EventArgs e)
{
base.OnPreInit(e); SiteUtils.SetupEditor(edContent, false, this);
}
and you would set the toolbar for it like this:
using mojoPortal.Web.Editor;
edContent.WebEditor.ToolBar = ToolBar.FullWithTemplates;
There are many examples in the code of existing features to help you figure it out
Hope that helps,
Joe
