This control does not work with firefox and chrome browsers. Only works with IE.

Sometimes this control does not render properly and only html text is displayed, to overcome this issue use the below function on the html part of page where you are using this control.


This function converts the text area to rich text control using function"RTE_ConvertTextAreaToRichEdit"

that is defined in the "/_layouts/1033/form.js" file.


<script type="text/javascript">

function CreateRichEdit(id) {

if (browseris.ie5up && browseris.win32 && !IsAccessibilityFeatureEnabled()) {

g_aToolBarButtons = null;

g_fRTEFirstTimeGenerateCalled = true;

RTE_ConvertTextAreaToRichEdit(id, true, true, "", "1033", null, null, null, null, null, "Compatible", "\u002f", null, null, null, null);

RTE_TextAreaWindow_OnLoad(id);

}

document.write("&nbsp;<br><SPAN class=ms-formdescription><a href='javascript:HelpWindowKey(\"nsrichtext\")'>Click for help about adding basic HTML formatting.</a></SPAN>&nbsp;<br>");

};

}
