I have my own component that modifies untyped dataset in design-time. After I calling that method of my component the dataset is modified correctly, but form still indicated unchanged. I save form and close it. When I open this form - Dataset lost all modifications. What I must do?

This is not VB specific at all. Have a look at the Framework groups,
probably m.p.d.framework.windowsforms.designtime.
