    protected void setRowToRow(DataRow dataRow, DataRow tempRow)
    {
        //tempRow["id"] = dataRow["id"];//主键唯一约束
        tempRow["type"] = dataRow["type"];
    }
    /// <summary>
    /// 上移
    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    protected void btnUp_Click(object sender, EventArgs e)
    {
        DataRow currentRow = ((DataTable)ViewState["dtTitles"]).Rows.Find(102);//根据主键获取当前row
        DataRow[] rows = ((DataTable)ViewState["dtTitles"]).Select();//获取table中所有的row
        int currentIndex = Array.IndexOf(rows, currentRow); //获取当前row的index
        DataRow tempRow = ((DataTable)ViewState["dtTitles"]).NewRow();
        setRowToRow(((DataTable)ViewState["dtTitles"]).Rows[currentIndex - 1], tempRow);
        setRowToRow(((DataTable)ViewState["dtTitles"]).Rows[currentIndex], ((DataTable)ViewState["dtTitles"]).Rows[currentIndex - 1]);
        setRowToRow(tempRow, ((DataTable)ViewState["dtTitles"]).Rows[currentIndex]);
        BindData();
    }
