Thanks for the pointer Tim... all the hard-work is done in the 'directoryBrowser.aspx'.

Here's what I quickly came up with - using the AbstractDataEditor class:

namespace Bodenko.Umbraco.DataType.FilePicker
{
    using System;
    using System.Collections.Generic;
    using System.Web.UI.HtmlControls;
    using System.Web.UI.WebControls;

    using umbraco.BusinessLogic;
    using umbraco.cms.businesslogic.datatype;

    public class FilePickerDataEditor: AbstractDataEditor   
    {
        private TextBox control = new TextBox();

        public FilePickerDataEditor()
        {
            this.RenderControl = this.control;
            this.control.Init += new EventHandler(this.control_Init);
            this.DataEditorControl.OnSave += new AbstractDataEditorControl.SaveEventHandler(this.DataEditorControl_OnSave);
        }

        public override Guid Id
        {
            get
            {
                return new Guid("318a9c2e-3966-4979-8c1d-575c5d5f669b");
            }
        }

        public override string DataTypeName
        {
            get
            {
                return "File Picker";
            }
        }

        private void control_Init(object sender, EventArgs e)
        {
            this.control.CssClass = "guiInputText";
            this.control.Style.Add("width", "330px");
            this.control.Text = this.Data.Value != null ? this.Data.Value.ToString() : String.Empty;

            // create the image
            HtmlImage image = new HtmlImage();
            image.Src = "images/foldericon.png";
            image.Style.Add("padding-left", "5px");

            // create the anchor link
            HtmlAnchor anchor = new HtmlAnchor();
            anchor.HRef = "javascript:void(0);";
            anchor.Attributes.Add("onclick", String.Format("javascript:top.openModal('developer/packages/directoryBrowser.aspx?target={0}', 'Choose a file or a folder', 400, 500); return false;", this.control.ClientID));

            // add the image to the anchor link
            anchor.Controls.Add(image);

            // add the anchor link to the data-type property
            this.control.Parent.Controls.Add(anchor);
        }

        private void DataEditorControl_OnSave(EventArgs e)
        {
            this.Data.Value = this.control.Text;
        }
    }
}

Once I've ironed out any bugs (and finished what I need to on my current project), I'll package up this data-type and release it as a project. :-)

Cheers, Lee.

Sweet, even easier then I thought

Nice Lee!

Hey Lee,

I have used your solution and it works very well. Thanks.
