You must be autogenerating your columns in the grid, in which case the
columns collection is empty, and you need to get a little trickier.
You can still access the style in the code behind, it just takes some goofiness.
First you need to access the header DataGridItem
DataGridItem dgiHeader = (DataGridItem)dg.Controls[0].Controls[1];
//Note that the datagrid object has one child control of the type
DataGridTable, the items are children of this and not the datagrid
directly, hence the .Controls[0]
//If you are not using a pager, you might need to use
(DataGridItem)dg.Controls[0].Controls[0]; to access the header item,
just check the ItemType property
Then you access the cell you want to change and set the style
TableCell tc =dgiHeader.Cells[0];
tc.CssClass = "SomeCSS";
