Answer 1

在网格 RowDataBound 事件中：

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (...){
            //hide controls
            foreach (Control c in e.Row.Controls)
            {
                 c.Visible=false;
            }
            //change color
            e.Row.Style.Add("background-color","red");
        }
    }

Answer 2

在 GridView1_RowDataBound 事件中，对不需要值的行执行以下操作。

    for (int i = 0; i < e.Row.Cells.Count; i++)
        {
             e.Row.Cells[i].Text = "";
        }

您可以这样做是 DataBinding 事件。

protected void GRIDVIEW_DataBinding(object sender, EventArgs e)
{
   foreach(GridViewRow grv in GRIDVIEW.Rows)
   {
     grv.Visible = (Condition_to_check_if_value_loaded_is_zero);
   }
}
