javascript - Input Data To SharePoint RichText Control By WinForms WebBrowser Control -

-

i need edit value in sp rich text field via winforms web browser control. other controls (input tags) easy , can change value quite simply. however, not simple rich text. headed on to: http://blog.drisgill.com/2007_05_01_archive.html

and got ideas. @ first, tried creatign javascript function , adding page:

function getrichtextrange(strbaseelementid)     var doceditor=rte_geteditordocument(strbaseelementid);     if (doceditor == null)     { return; }     var selection = doceditor.selection;     var range = selection.createrange();     return range; }

however, every time call this, null value back. tried instead:

object doceditor = document.invokescript("rte_geteditordocument", new object[] { fieldname }); ihtmldocument2 doc = (ihtmldocument2)doceditor; ihtmlselectionobject selection = doc.selection; ihtmltxtrange textrange = (ihtmltxtrange)selection.createrange(); textrange.pastehtml(value);

well, getting error on second line: "unable cast object of type 'system.dbnull' type 'mshtml.ihtmldocument2"

i not sure if casting correct object type anyway, in case, seems getting rte_geteditordocument function of system.dbnull.

all want myrichtexthtmlelement.setattribute("value", html); cannot done.

to make things worse, new javascript , i'm more of winforms guy, html not hot stuff. below html richtext field:

<tr>   <td nowrap="true" valign="top" width="190px" class="ms-formlabel">     <h3 class="ms-standardheader">       <nobr>richtext</nobr>     </h3>   </td>   <td valign="top" class="ms-formbody">     <!-- fieldname="richtext"              fieldinternalname="richtext"              fieldtype="spfieldnote"           -->     <span dir="none">       <div class='ms-rtestate-field ms-rtefield' style=''>         <div id='ctl00_m_g_29d60052_5630_4981_8452_850a87a50b56_ctl00_ctl05_ctl07_ctl00_ctl00_ctl04_ctl00_ctl00_textfield_inplacerte_label'              style='display:none'>rich text editor         </div>         <div class=' ms-rtestate-write ms-rteflags-0'              id='ctl00_m_g_29d60052_5630_4981_8452_850a87a50b56_ctl00_ctl05_ctl07_ctl00_ctl00_ctl04_ctl00_ctl00_textfield_inplacerte'              style='min-height:84px'              aria-labelledby='ctl00_m_g_29d60052_5630_4981_8452_850a87a50b56_ctl00_ctl05_ctl07_ctl00_ctl00_ctl04_ctl00_ctl00_textfield_inplacerte_label'              contenteditable='true' >           <div class="externalclassd74b4d64d01941cdb34619757aaa30d8">             <html>               <body>                 <h4>a definition list:</h4>                 <dl>                   <dt>coffee</dt>                   <dd>black hot drink</dd>                   <dt>milk</dt>                   <dd>white cold drink</dd>                 </dl>               </body>             </html>           </div>         </div>         <div style="clear:both;"></div>       </div>       <span dir="ltr">         <input name="ctl00$m$g_29d60052_5630_4981_8452_850a87a50b56$ctl00$ctl05$ctl07$ctl00$ctl00$ctl04$ctl00$ctl00$textfield_spsave"                type="hidden"                id="ctl00_m_g_29d60052_5630_4981_8452_850a87a50b56_ctl00_ctl05_ctl07_ctl00_ctl00_ctl04_ctl00_ctl00_textfield_spsave" />       </span>     </span>   </td> </tr>

do have use winforms webbrowser control? 1 use whatever html code editor wanted in winform , capture results , use sharepoint web services or object model(depending on use case) update item alternative option.
