How do I, at run-time,right justify a column that will be displaying a deciimal?
I assume you mean you want to right-justify the text in the column, not the column itself. I think numeric values riht-align by default, don't they? Either way, you can control this by use column.CellAppearance.TextHAlign.
How can I pad columns with extra pixels?
For example if col A is right aligned and col B is left aligned, i want to padd col A with a few pixels.
how can i do that ?
You can use the CellPadding property.
