Question

When I update a table from a Form through Autogenerated EF, if I remove some data-columns from the view form because I don’t want to be editable, that columns are updated with null value, how can avoid this behavior? I read here: Entity Framework: Ignore Columns removing it from the model, but not always I want to ignore these datacolumns.

thank!

asp.net MVC provide you with UpdateModel method, look on the overload

protected internal void UpdateModel<TModel>(
TModel model,
string prefix,
string[] includeProperties,
string[] excludeProperties
)
where TModel : class

using it you are able to exclude or include particular properties by their names
