GridView分页的使用

1.       先把gridview(GridViewX)控件拖放到界面上，绑定数据（bind()）；同时对DropDownList做如下操作：this.ddlCurrentPage.Items.Clear();

        for (int i = 1; i <= this.GridViewX.PageCount; i++)

        {

            this.ddlCurrentPage.Items.Add(i.ToString());

        }

1.           this.ddlCurrentPage.SelectedIndex = this.GridViewX.PageIndex;

2.       设置gridview的属性AllowPaging="True" PageSize="n"

3.       拖放几个LinkButton按钮，分别设置如下：

    <asp:LinkButton ID="lnkbtnFrist" runat="server" OnClick="lnkbtnFrist_Click">首页</asp:LinkButton>

    <asp:LinkButton ID="lnkbtnPre" runat="server" OnClick="lnkbtnPre_Click">上一页</asp:LinkButton>

<asp:LinkButton ID="lnkbtnNext" runat="server" OnClick="lnkbtnNext_Click">下一页</asp:LinkButton>

<asp:LinkButton ID="lnkbtnLast" runat="server" OnClick="lnkbtnLast_Click">尾页</asp:LinkButton>

4.        设置几个文本按钮的事件处理函数：

    protected void lnkbtnPre_Click(object sender, EventArgs e)

    {

        if (this.GridViewX.PageIndex > 0)

        {

            this.GridViewX.PageIndex = this.GridViewX.PageIndex - 1;

            bind();

        }

    }

    protected void lnkbtnNext_Click(object sender, EventArgs e)

    {

        if (this.GridViewX.PageIndex < this.GridViewX.PageCount)

        {

            this.GridViewX.PageIndex = this.GridViewX.PageIndex + 1;

            bind();

        }

    }

    protected void lnkbtnLast_Click(object sender, EventArgs e)

    {

        this.GridViewX.PageIndex = this.GridViewX.PageCount;

        bind();

 }

5.DropDownList的事件处理函数：

    protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)

    {

        this.GridViewX.PageIndex = this.ddlCurrentPage.SelectedIndex;

        bind();

}
