GridView分页

首先添加一个GridView的模板列

前台：

//添加GridView模板列
<PagerTemplate>
                            <asp:Label ID="CurrentPageLabel" ForeColor="Blue" runat="server" Text="当前页：" />&nbsp;
                            <asp:LinkButton id="FirstPage" runat="server" CommandArgument="FIRST" CommandName="Page">首页</asp:LinkButton>
                            <asp:linkbutton  id="PreviousPage" runat="server" CommandArgument="Prev" CommandName="Page">上一页</asp:linkbutton>
                            <asp:linkbutton  id="NextPage"  runat="server" CommandArgument="NEXT" CommandName="Page">下一页</asp:linkbutton>
                            <asp:linkbutton  id="LastPage"  runat="server" CommandArgument="LAST" CommandName="Page">尾页</asp:linkbutton>
                            <asp:label id="Lab3"  runat="server" ForeColor="Blue" Height="7px" Font-Size="12px"></asp:label>
                            <asp:Label ID="MessageLabel" ForeColor="Blue" Text="页码:" runat="server" />
                            <asp:DropDownList ID="PageDropDownList" AutoPostBack="true" runat="server" OnSelectedIndexChanged="PageDropDownList_SelectedIndexChanged" />&nbsp;
                        </PagerTemplate>

 后台：

protected void GridView1_DataBound(object sender, EventArgs e)
    ...{
        try
        ...{
            GridViewRow pagerRow = GridView1.BottomPagerRow;

            LinkButton FirstPage = (LinkButton)pagerRow.Cells[0].FindControl("FirstPage");
            LinkButton PreviousPage = (LinkButton)pagerRow.Cells[0].FindControl("PreviousPage");
            LinkButton NextPage = (LinkButton)pagerRow.Cells[0].FindControl("NextPage");
            LinkButton LastPage = (LinkButton)pagerRow.Cells[0].FindControl("LastPage");

            if (GridView1.PageIndex == 0)
            ...{
                FirstPage.Enabled = false;
                PreviousPage.Enabled = false;
            }
            else if (GridView1.PageIndex == GridView1.PageCount - 1)
            ...{
                LastPage.Enabled = false;
                NextPage.Enabled = false;
            }
            else if (GridView1.PageCount <= 0)
            ...{
                FirstPage.Enabled = false;
                PreviousPage.Enabled = false;
                NextPage.Enabled = false;
                LastPage.Enabled = false;
            }
            DropDownList pageList = (DropDownList)pagerRow.Cells[0].FindControl("PageDropDownList");
            Label pageLabel = (Label)pagerRow.Cells[0].FindControl("CurrentPageLabel");

            if (pageList != null)
            ...{
                for (int i = 0; i < GridView1.PageCount; i++)
                ...{
                    int pageNumber = i + 1;
                    ListItem item = new ListItem(pageNumber.ToString() + "/" + GridView1.PageCount.ToString(), pageNumber.ToString());
                    if (i == GridView1.PageIndex)
                    ...{
                        item.Selected = true;
                    }
                    pageList.Items.Add(item);

                }

            }
            if (pageLabel != null)
            ...{
                int currentPage = GridView1.PageIndex + 1;
                pageLabel.Text = "当前页：" + currentPage.ToString() +
                  " / " + GridView1.PageCount.ToString();
            }

     catch ...{ }
    }
