I'm just trying to follow the example. Instead of IsActive/boolean, I'm trying to do CustomerNumber/string.
protected override Expression<Func<TEntity, bool>> CreateFilterExpression<TEntity>()
{
var expression = base.CreateFilterExpression<TEntity>();
if (typeof(IIsActive).IsAssignableFrom(typeof(TEntity)))
{
Expression<Func<TEntity, bool>> isActiveFilter =
e => !IsActiveFilterEnabled || EF.Property<bool>(e, "IsActive");
expression = expression == null
? isActiveFilter
: QueryFilterExpressionHelper.CombineExpressions(expression, isActiveFilter);
}
return expression;
}
