Hi I've tried to change all of the lines vertical and horizontal in my `GridView` from the code behind using the code shown below, but this does not seem to have any effect.

Can anyone offer a solution with the code behind please?

```
foreach (GridViewRow row in gvCurrentStageCircsPSTN.Rows)
{
  foreach (TableCell cell in row.Cells)
  {
    cell.Width = 150;
    cell.Height = 20;
    cell.Attributes.CssStyle["text-align"] = "center";
  }
}

```
