problem with UpdateCommand

[mww]

In my grid I have 3 columns, a combo, textbox and RADUpload

in the UpdateCommand event I create an instance of the combo, textbox and RADUpload
If the user hasnt uploaded any files, I want to keep the original uploadURL values, How can I get to them from the UpdateCommand Event ?

the datasource bound to the grid is simply a list of a custom class Ive created

public class CastMemberObj
    {
        public int ID { get; set; }
        public string CastMemberName { get; set; }
        public string CastMemberInformation { get; set; }
        public string PhotoURL { get; set; }
        public string ThumbnailURL { get; set; }
        public string Type { get; set; }
    }

  So in the UpdateCommande event I simply want to get access to the contents of the original PhotoURL & ThumbnailURL
These arent displayed in the grid, but they are part of the datasource.

protected void RadGridCast_UpdateCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)
        {
            var editableItem = ((GridEditableItem)e.Item);
            var productId = (int)editableItem.GetDataKeyValue("ID");
            TheCompanyBL.CastMemberObj castmember = new TheCompanyBL.CastMemberObj();
            string thumbURL = string.Empty;
            string ImageURL = string.Empty;
            string url = TheCompanyBL.Helpers.GetSiteURL();
            string ImageUploadURL = url + "/Uploads/";

            RadTextBox tb = (RadTextBox)e.Item.FindControl("txbCastMember");
            if (tb != null)
            {
                castmember.CastMemberName = tb.Text;
            }
            else
            {
                castmember.CastMemberName = "";
            }

            RadComboBox rcb = (RadComboBox)e.Item.FindControl("RadComboBoxType");
            if (rcb != null)
            {
                castmember.Type = rcb.SelectedValue;
            }
            else
            {
                castmember.Type = "";
            }



            TheCompanyBL.CastMemberObj member = (TheCompanyBL.CastMemberObj)e.Item.DataItem;
            Image img = (Image)e.Item.FindControl("ImageThumbNail");
            if (null != img)
            {

            }
            RadUpload ru = (RadUpload)e.Item.FindControl("RadUploadImage");
            if (null != ru)
            {
                string target = Server.MapPath(ru.TargetFolder);

                if (ru.UploadedFiles.Count > 0)
                {
                    string sFileType = ru.UploadedFiles[0].GetExtension();
                    foreach (UploadedFile f in ru.UploadedFiles)
                    {
                        imagemanager.ResizeAndSave(ru.UploadedFiles[0], ImageUploadURL, target, "CastMembers", true, out thumbURL);
                        imagemanager.ResizeAndSave(ru.UploadedFiles[0], ImageUploadURL, target, "CastMembers", false, out ImageURL);
                        castmember.ThumbnailURL = thumbURL;
                        castmember.PhotoURL = ImageURL;
                    }
                }
            }
            //retrive entity form the Db

            //update entity's state
            //editableItem.UpdateValues(castmember);
            string err = castmembermanager.Update(castmember);
        }

Ive tried to cast the dataItem to my custom class but its always null

TheCompanyBL.CastMemberObj member = (TheCompanyBL.CastMemberObj)e.Item.DataItem;  

can anyone help me out ?

Mww,

I use the below to access the value of a cells that are not being displayed. I do this during the ItemCommand of my RadGrid. I hope I understood your scenario correctly and that this helps.

Thanks,
Casey

protected void RadGridCast_UpdateCommand(object source, GridCommandEventArgs e)
    {
        // code
        TheCompanyBL.CastMemberObj member = (TheCompanyBL.CastMemberObj)e.Item.Cells[x].Text.ToString();
        //'x' represents the index of the cell. You may
        //have to play around with which number picks the right cell
        //for my RadGrid the 0 and 1 cells were blank spaces
    }
