问一个简单的问题，关于获取gridview的无数据状态

Question

我想获取gridview无数据状态，怎么写啊？
类似于，这个是如果gv的行数为0，就显示无出货，但是不对！！if (GridView1.Rows.Count = 0)
                {
                    Label15.Text = "无出货！";
                }

Answer 1

if (ds.Tables[0].Rows.Count == 0)
        {
            ds.Tables[0].Rows.Add(ds.Tables[0].NewRow());            GridView1.DataSource = ds;            GridView1.DataBind();            int columnCount = GridView1.Rows[0].Cells.Count;            GridView1.Rows[0].Cells.Clear();            GridView1.Rows[0].Cells.Add(new TableCell());            GridView1.Rows[0].Cells[0].ColumnSpan = columnCount;            GridView1.Rows[0].Cells[0].Text = "没有记录被查询到";            this.GridView1.SelectedIndex = -1;        }

Answer 2

if (GridView1.DataSource==null)
                {
                    Label15.Text = "无出货！";
                }

Answer 3

        {
            Label15.Text = "无出货！";
