GridView分页后的跳转问题！

Question

<PagerTemplate> 
<asp:LinkButton ID="lbFirst" runat="server" CausesValidation="False" CommandArgument="First" 
CommandName="Page">首页 </asp:LinkButton> 
<asp:LinkButton ID="lbPrev" runat="server" CausesValidation="False" CommandArgument="Prev" 
CommandName="Page">上一页 </asp:LinkButton> 
<asp:LinkButton ID="lbNext" runat="server" CausesValidation="False" CommandArgument="Next" 
CommandName="Page">下一页 </asp:LinkButton> 
<asp:LinkButton ID="lbLast" runat="server" CausesValidation="False" CommandArgument="Last" 
CommandName="Page">尾页 </asp:LinkButton> 第 <asp:Label ID="Label2" 
runat="server" Text=" <%#((GridView)Container.Parent.Parent).PageIndex + 1 %>"> </asp:Label>页 
共 <asp:Label ID="Label1" runat="server" Text=" <%# ((GridView)Container.Parent.Parent).PageCount %>"> </asp:Label>页 
跳到 <asp:TextBox ID="tbPage" runat="server" Text=" <%# ((GridView)Container.Parent.Parent).PageIndex + 1 %>" 
Width="27px"> </asp:TextBox> 
<asp:LinkButton ID="lbGO" runat="server" CausesValidation="False" CommandArgument="-1" 
CommandName="Page" Text="GO"> </asp:LinkButton> 
</PagerTemplate> 
分页事件 
    protected void borrowGridView_PageIndexChanging(object sender, GridViewPageEventArgs e) 
    { 
        GridView gvw = (GridView)sender;         if (e.NewPageIndex < 0) 
        { 
            TextBox pageNum = (TextBox)gvw.BottomPagerRow.FindControl("tbpage");             int Pa = int.Parse(pageNum.Text); 
            if (Pa <= 0) 
                gvw.PageIndex = 0; 
            else 
                gvw.PageIndex = Pa - 1;         } 
        else 
        { 
            gvw.PageIndex = e.NewPageIndex; 
        }         borrowGridView.DataSource = sa.selAssertBorrow(); 
        borrowGridView.DataBind(); 
    } 
　　　　首页　上一页　下一页　尾页　第？页　共？页　跳到(文本框)页GO 
     前台和后台代码都在上面，帮忙修改一下代码！　要实现点GO后要获取文本框里面的值，根据值跳转到GridView中指定的页！　帮忙`````````` 在源代码上修改！

Answer 1

在 Go 这个按钮的服务器端事件中，直接绑定数据源，然后设置 GridView 的 PageIndex 值即可！

Answer 2

GridViewRow pagerRow = GridView1.BottomPagerRow;
TextBox pageNum = (TextBox)pagerRow.Cells[0].FindControl("tbpage");

Answer 3

有道理，只要能读到PageIndex就好了

 <PagerTemplate> 
            <asp:LinkButton ID="lbFirst" runat="server" CausesValidation="False" CommandArgument="First" Enabled="false" 
                CommandName="Page">首页 </asp:LinkButton> 
            <asp:LinkButton ID="lbPrev" runat="server" CausesValidation="False" CommandArgument="Prev" Enabled="false"
                CommandName="Page">上一页 </asp:LinkButton> 
            <asp:LinkButton ID="lbNext" runat="server" CausesValidation="False" CommandArgument="Next" 
            CommandName="Page">下一页 </asp:LinkButton> 
            <asp:LinkButton ID="lbLast" runat="server" CausesValidation="False" CommandArgument="Last" 
                CommandName="Page">尾页 </asp:LinkButton> 第 <asp:Label ID="Label2" 
            runat="server" Text=" <%#((GridView)Container.Parent.Parent).PageIndex + 1 %>"> </asp:Label>页 
            共 <asp:Label ID="Label1" runat="server" Text=" <%# ((GridView)Container.Parent.Parent).PageCount %>"> </asp:Label>页 
            跳到 <asp:TextBox ID="tbPage" runat="server" Text=" <%# ((GridView)Container.Parent.Parent).PageIndex + 1 %>" 
            Width="27px"> </asp:TextBox> 
            <asp:LinkButton ID="lbGO" runat="server" CausesValidation="False" CommandArgument="-1" 
            CommandName="Pageindex" Text="GO"> </asp:LinkButton> 
            </PagerTemplate> 
CS代码:
    protected void GridView1_RowCommand1(object sender, GridViewCommandEventArgs e)
    {
        if (e.CommandName == "Pageindex")
        {
           TextBox tb=GridView1.BottomPagerRow.FindControl("tbPage") as TextBox;
           int pageindex = Convert.ToInt32(tb.Text);
           GridView1.PageIndex = pageindex-1;
           GridView1.DataSource = (DataView)Session["temp"];
           GridView1.DataBind();
        }
    }    protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
    {        GridView1.PageSize = 4;
        GridView1.PageIndex = e.NewPageIndex;
        GridView1.DataSource=(DataView)Session["temp"];
        GridView1.DataBind();
    }这样就可以了

Answer 6

前台代码跟你一样,只是改了             <asp:LinkButton ID="lbGO" runat="server" CausesValidation="False" CommandArgument="-1" 
            CommandName="Pageindex" Text="GO"> </asp:LinkButton> 
这里的CommandName="Pageindex"
Session里存的是数据

Answer 7

<asp:LinkButton ID="lbGO" runat="server" CausesValidation="False" CommandArgument="-1" 
CommandName="Page" Text="GO" OnClick="GoIndex"> </asp:LinkButton>//添加对lbGO单击事件
protected void GoIndex(object sender, EventArgs e)
{
        GridViewRow pagerRow = GridView1.BottomPagerRow;
        TextBox pageNum = pagerRow.Cells[0].FindControl("tbpage") as TextBox;
        if(pageNum.Text!=null)
        GridView1.PageIndex = Convert.ToInt32(pageNum.Text)-1;
}protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
   if(e.NewPageIndex>=0&&e.NewPageIndex<GridView1.PageCount)
        GridView1.PageIndex = e.NewPageIndex;
   gview_bind();  //绑定数据源
}这样就可以了
