Question

NTEXT with more than 4000 characters in SQL Server CE in windows phone

I have a database in my windows phone app with a ntext field in one of the tables

Answer 1

I think your column in the actual database file is not ntext, for whatever reason.

This works fine for me:

    using (NorthwindContext ctx = new NorthwindContext(NorthwindContext.ConnectionString))
    {
        ctx.DeleteDatabase();
        ctx.CreateDatabase();
        var category = new Categories();
        category.CategoryName = "Test";
        category.Description = new string('x', 6666);
        ctx.Categories.InsertOnSubmit(category);
        ctx.SubmitChanges();

        var testCat = ctx.Categories.First();
        if (testCat.Description.Length == 6666)
        {
            MessageBox.Show("Works on my Windows Phone");                
        }
    }

Column declaration:

[global::System.Data.Linq.Mapping.ColumnAttribute(Storage="_Description", DbType="NText", UpdateCheck=UpdateCheck.Never)]
        public string Description
        {
            get
            {
                return this._Description;
            }
            set
            {
                if ((this._Description != value))
                {
                    this.OnDescriptionChanging(value);
                    this.SendPropertyChanging();
                    this._Description = value;
                    this.SendPropertyChanged("Description");
                    this.OnDescriptionChanged();
                }
            }
        }
