Fro attention of fredck (FCKeditor web part)

Hi There.

I have registered at http://dev.fckeditor.net/ as ( sharepointuk ).
Hop this helps, just let me know what i need to do about the iance thing if this is any good to ya.



Here is the code that i worte.
I have tested it in both users scopes with multimly instance of the web part on the page and all ok.

using System;
using System.Collections;
using System.ComponentModel;
using System.Drawing;
using System.Security.Permissions;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
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();
            }
        }
    }
}

Step 1: Add file to App_Code folder
Step 2: Add web part to catalouge in web parts manager
Step 3: Log in and open up catalouge view and add web part to page.
Step 4: open edit view and now the web parts edit function is avaiable.
Step 5: Hit edit and the editors zone of the web part manager appears with fck eiftor as the text editor.



You can see where i set the base bath i createchildcontrols. You can set all your other options here. Intellsens works fine on _contentToEdit.Whatever. It would not take too much work to allow all these function via the editor zone as well. So each implemation of the web part cn have sperate setting like the inpage version.

May have a bit of time to do bit some work on it if ya ned as well.

Thanks Karl.

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>

This enables the designated user to enter shared scope for web parts that support this. Remeber you have to supply a link to enable the user to switch scope.
