GridView技巧-增加序號列

方法一(支持分頁): 正常情況下,數據綁定的時候GridView模版列內部的數據綁定對象Container是GridViewRow類型,

再根據GridViewRow.Parent.Parent獲得當前GridView的引用, 計算出他的當前Index;

<asp:TemplateField HeaderText="序號">

                <ItemTemplate>
                    <asp:Label ID="lblIndexCount" runat="server" Text='<%# ((GridView)((GridViewRow)Container).Parent.Parent).PageIndex * ((GridView)((GridViewRow)Container).Parent.Parent).PageSize + ((GridView)((GridViewRow)Container).Parent.Parent).Rows.Count + 1%>' />
                </ItemTemplate>

            </asp:TemplateField>
