My database hase a field that is integer ,i can't get it to function with Check Box

Yes, you should add a new property to your model which converts to and from integer. Add a partial class for the model and something like this:

public partial class MyModel
{
     public bool BoolProperty
     {
        get
        {
           return this.IntegerProperty != 0;
        }
        set
        {
           this.IntegerProperty = value ? 1 : 0;
        }
     }
}
