using System.Web.UI.WebControls.WebParts;
using FredCK.FCKeditorV2;

namespace SharepointUK.TextEditor
{
    [AspNetHostingPermission(SecurityAction.Demand,
      Level = AspNetHostingPermissionLevel.Minimal)]

    [AspNetHostingPermission(SecurityAction.InheritanceDemand,
      Level = AspNetHostingPermissionLevel.Minimal)]

    public class TextDisplayWebPart : WebPart
    {
        private String _contentText = "add content here";

        Label DisplayContent;

        Literal lineBreak;

        public override EditorPartCollection CreateEditorParts()
        {
            ArrayList editorArray = new ArrayList();

            TextDisplayEditorPart edPart = new TextDisplayEditorPart();

            edPart.ID = this.ID + "_editorPart1";

            editorArray.Add(edPart);

            EditorPartCollection editorParts = new EditorPartCollection(editorArray);

            return editorParts;
        }

        public override object WebBrowsableObject
        {
            get { return this; }
        }

        [Personalizable(), WebBrowsable]
        public String ContentText
        {
            get { return _contentText; }
            set { _contentText = value; }
        }


        protected override void CreateChildControls()
        {

            Controls.Clear();

            DisplayContent = new Label();

            DisplayContent.Text = this.ContentText;

            this.Controls.Add(DisplayContent);

        }


        [AspNetHostingPermission(SecurityAction.Demand,
          Level = AspNetHostingPermissionLevel.Minimal)]

        private class TextDisplayEditorPart : EditorPart
        {

            FCKeditor _contentToEdit;

            public override bool ApplyChanges()
            {
                TextDisplayWebPart part = (TextDisplayWebPart)WebPartToEdit;

                part._contentText = _contentToEdit.Value;

                return true;
            }

            public override void SyncChanges()
            {
                TextDisplayWebPart part = (TextDisplayWebPart)WebPartToEdit;
            }

            protected override void CreateChildControls()
            {
                Controls.Clear();

                _contentToEdit = new FCKeditor();

                _contentToEdit.BasePath = "~/fckeditor/";

                this.Controls.Add(_contentToEdit);

            }

            protected override void RenderContents(HtmlTextWriter writer)
            {
                _contentToEdit.RenderControl(writer);

                writer.WriteBreak();
            }
        }
    }
}

Thanks Fredck

All done on the agrement.



Here is a very good link to MSDN Libary that put me on the right road to creating this web part.

http://msdn.microsoft.com/en-us/library ... table.aspx

I will revisit this code after christmass and post a full working web site with example as there are many parts that make up a web portal with web parts.



Notes to intrested parties.....


You need to implment these functions to get a basic ASP.NET web portal working.

http://quickstarts.asp.net/QuickStartv2 ... fault.aspx

Understanding this will enable you to do a lot.

But this has nothing to do with web parts

a good book for web parts is.

Pro ASP.NET 3.5 Server Controls & Ajax Components (apress - Rob Cameron and Dale Michalk) 10 out of 10.

The first MSDN link is also a ver good link to getting the basics working well. ~ It shows you how to tye in things and how to implement your own soloution.


Pitfalls

My main pit fall when reasearching this subject was.

1: Editing in shared shope.

This whole subject is not well documented, but this is megga important. By default the web parts are only enabled in user scope. You have to give the mechenisim to switch to shared scope.

You enable shared scope in the web config like this

    
<webParts>
      <personalization>
        <authorization>
          <allow roles="admin" verbs="enterSharedScope"/>
          <allow users="contentadmin" verbs="enterSharedScope"/>
        </authorization>
      </personalization>
    </webParts>
