Use CSS to hide the column.

When you use .NET code and you set something to Visible=False that control is not rendered. This means that no HTML code is generated for this control.

If you need this to exist client side (so that you can do calculations client side) then you need to hide the element using CSS.

To hide an element you can do one of 2 things with CSS.
You can use "visible:hidden" or "display:none".

If you use visible:hidden then the element is hidden but the space that it takes up will still show up.

If you use display:none then the element is not displayed...therefore there is no gap where the element should be like when you use visible:hidden.

Check out w3c for more information on the visible style and the display style.

I prefer to use display:none because then there is no invisible object taking up room for no reason....but there are some circumstances where this could be useful.

So try:

<asp:BoundField DataField="GLAC_NAME" HeaderText="A/cNo">
  <ItemStyle CssClass="hideElement"  />
  <HeaderStyle  CssClass="hideElement"  />
</asp:BoundField>

Where you have a CSS class defined as:

.hideElement{
  display:none;
}

This will hide the header for the column and the column data itself.
