Serious problem in C#.NET Form Designer!?

Question

In C#.NET Form Designer: I can't refer from a form to objects which are in other forms. For example I have a grid on one form and I wanted to set its datasource to a DataSet which is on an other form. Or I would also want to refer to an imagelist which is also on the other form. I don't want to place all the common necessary resources onto all form where I want to use them. It would be a huge REDUNDANCY! I COULD DO THIS IN DELPHI!!!! :( I want to do this in DESIGN TIME! Ok, it is can be done in runtime, but in that case e.g I can't see my pictures in design time... , I can't retrieve the fields from a dataset to a treelist to set column properties in design time, ect.. Is there any solution for it? please help
