We have in our project used some editors on pages. So far we have used them and they have done what we needed until now.

We are basicly using this codes.

<EPiServer:Property PropertyName="MyLongStringProperty" id="HtmlEditor" EditMode="true" runat="server" />

Init function()
{Page.ClientScript.RegisterClientScriptInclude("system.js", ((PageBase)Page).ResolveUrlFromUI("javascript/system.js")); Page.ClientScript.RegisterClientScriptInclude("system.aspx", ((PageBase)Page).ResolveUrlFromUI("javascript/system.aspx")); Page.ClientScript.RegisterClientScriptInclude("episerverscriptmanager.js", ((PageBase)Page).ResolveUrlFromUtil("javascript/EPiServerScriptManager.js")); PropertyXhtmlString xhtmlString = new PropertyXhtmlString(); // select chosen options or use EditorToolOption.All // EditorToolOption.Bold | EditorToolOption.Italic | EditorToolOption.Underline; xhtmlString.EditorToolOptions = EditorToolOption.All; xhtmlString.Name = "MyLongStringProperty"; HtmlEditor.InnerProperty = xhtmlString;
}

public string Value
        {
            get
            {
                ((PageBase)Page).SetValuesForPropertyControls(HtmlEditor);
                return HtmlEditor.PropertyValue as string;
            }
            set
            {
                ((PageBase)Page).SetValuesForPropertyControls(HtmlEditor);
                HtmlEditor.InnerProperty.Value = value;
            }
        }

So when i load the page i have no value on the editor, and when i then select something in a drop down i load data from database and set the value and the edit loads with the new data. However after that it's like the data in the editor ish cached somehow.((PageBase)Page).SetValuesForPropertyControls(HtmlEditor); <- automaticly loads the first loaded value (from drop down/database).
But then the value is changed by the code and i can confirm it with VS debug, but the editor it self dont update it still shows the old (first) value.

I have tried many different things like "HtmlEditor.InnerProperty.LoadData(value);" and "HtmlEditor.InnerProperty.Clear();" first even, but nothing seems to help.

Anyone got some kind of ideas here ?
As posted in the CMS6 R2 Forum , we do run the newly CMS6 R2 as episerver.
