How to set Table/TableRow/TabelCell width by percent in code behind in asp.net?

Question

How do I set width with percent in code behind? The only option I can think of is taking the parent width and calculate by percent.i.e. TableRow.Width = Table.Width.V

Answer 1

Will this not work? Although I'm not entirely sure why you'd want a table row to be 25% of an overall table's width

TableRow.Width = new Unit("25%")
