I'm not sure if this is correct so don't want to edit question but I believe the question is: "How can I change the three labels visibility in `ItemTemplate`?" — Sayse, Aug 30 '13 at 10:32

In the Rowcommand in the grid you can Hide or shows item templates for example:

void CustomersGridView_RowDataBound(Object sender, GridViewRowEventArgs e)
  {

    if(e.Row.RowType == DataControlRowType.DataRow)
    {
      //Your Condition
      Label lblproductname = (Label)e.Row.FindControl("lblproductname")
      If(a > B)
         lblproductname.Visible = true;
      //Others Lables
      ....

    }

  }

I hope that help.

protected void OnRowCreated(object sender, GridViewRowEventArgs e)
{
         e.Row.Cells[columnIndex].Visible = false;
}

The only workaround I can suggest is to give a HeaderText on ASPX Page and then find using that.

protected void xyz()
{
    ((DataControlField)youGridView.Columns
            .Cast<DataControlField>()
            .Where(fld => fld.HeaderText == "your header text")
            .SingleOrDefault()).Visible = false;
}

I believe that your question is answered here:

How to find control in TemplateField of GridView?

Copied from the answer:

foreach(GridViewRow row in GridView1.Rows) {
    if(row.RowType == DataControlRowType.DataRow) {
        Label myLabel = row.FindControl("myLabelID") as Label;
        myLabel.Visible = false;
    }
}

From RowDataBoundEvent:

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if(e.Row.RowType == DataControlRowType.DataRow)
    {
        Label myLabel = e.Row.FindControl("myLabelID") as Label;
        myLabel.Visible = false;
    }
}
