This is driving me crazy. I need to hide rows that a particular cell is
zero. On debuggng I fiound out that ItemDataBound fires for header only
and not for Item and AlternatingItem
private void grdSelectionList_ItemDataBound(object sender,
System.Web.UI.WebControls.DataGridItemEventArgs e)
{
  if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType ==
ListItemType.AlternatingItem )
{
    if (e.Item.Cells[2].Text == "0")
    {
       e.Item.Visible = false;
    }
}

Any help on this will be appreciated.

That piece of code you pasted should work well. Your code also eliminates
the header row.

Look for the problem some place else. If you still cannot resolve, paste the
rest of the code  you have.

also, unless your datasource is not returning any rows, in which case only
the header row will show. This is logical ofcourse =P

The datasource returns many rows. On testing, the itemDataBind fires
only once and e.Item.ItemType.TString() return 'header'

I now know the cause of the problem but not the solution. The column 2
is a TemplateColumn populated with data but e.Item.Cells[2].Text
returns empty string. All other cells which are databond return correct
values. This seems to be a fundamental misunderstandig on my behalf.
Any idea how can I solve this?

Found the solution! For TemplateColumn the FindControl must be used:

Label lbl = (Label)e.Item.Cells[2].FindControl("label_ID");
if (lbl.Text == "0")
{
e.Item.Visible = false;
}
