I'm looking for how to set the error markers (red ! marks) in a Windows.Forms.Datagrid. After research I believe they appear after some validation routine, but how do I set these manually? E.g. If each row goes to a stored procedure I'd like to place an error marker whenever the SP returns an error

I like to know how to make the forms buttons and text and data... auto adjust when windows Maximize or minimaze..because when its big I can see everything fine and when I restore to a smaller window the buttons are on the bottom and cant see them... Basically I want everything to look in the same position whether its a small window or big or at least that it has scroolbars if I see it small.

OK, in it's simpest terms, I have a custom object (all string Items) which I add to a list of those items. The list is declared as a global variable. One form updates the list, another contains a dataGridView (vs.net 3.5) that displays the list items. The view displays the correct data. For some reason, if I select a header in the dgv before it's populated, that's fine, but if I select it (click anywhere with the mouse) it bugs out with an Index = -1 error from the System.Windows.Forms. CurrencyManager.get_Item(Int32 index) bit.
