[Solved] Initialize filter dynamically

[Vinicius]

Hi, I would like to initialize the grid filter using a GridCommand, for that I need to create an Expression Tree of type Expression<Func<T, string>> so a can pass it to the .Add method:

grid.Filters(y => y.Add(HERE))

Does anyone knows how to create this expression tree using System.Linq.Expression instead of passing a lambda expression?

Here is the solution:

ParameterExpression p = Expression.Parameter(typeof(T));
var exp = Expression.Lambda<Func<T, string>>(Expression.Property(p, filter.Member), p);
grid.Filterable(x => x.Filters(y => y.Add(exp).Contains(filter.Value.ToString())));
