Can you give me an example to override the CreateFilterExpression method using a string value for the query filter? Your example is using a bool. I want to have a global query filter that will filter by customer number, just like a tenant id. I followed your example but not able to get it to work with a string.

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; }Markdown supported.Copy, paste, or drag & drop images and files (max 100 MB per file, 100 MB total per post) -

hi
The expression must be
Expression<Func<TEntity, bool>>If you have a string column you can try toExpression<Func<TEntity, bool>> myStringFilter = e => !IsMyFilterEnabled || EF.Property<string>(e, "MyString") == CurrentString;Markdown supported.Copy, paste, or drag & drop images and files (max 100 MB per file, 100 MB total per post)
