For instance, each form will have a DataGridView, many of the same buttons, much of the same UI code and so on. I'd like to implement this by creating a base version of this common form, subclass it for all these very-similar-but-not-quite-the-sam...

Can anyone see any problems with this or should it work in all cases? (1) Is type of Item.Owner a ToolStrip? (2) Yes, Return Item.Owner (3) No, Item = Item.Ow...
My winforms application is rendering very choppy. Is there a technique that can be used to either draw a form off screen, or to have it be hidden until the layout has been processed? Anything to help speed up the visual load of my forms. Thanks for any help. edit: Forms have a couple grids each, and around 20 - 30 additional control...

Using some excerpts from Marc's code : DataTable table = new DataTable(); table.Columns.Add("ID...
I have a database containing two tables, Products and Licences. Licences.ProductID has a foreign key reference to Products.ProductID (i.e. licenses for that product).
