显示寻呼机行，但在 Gridview 中隐藏页码

Question

简单的问题。

我有一个 ASP.net GridView (VS2005)，它有页码，但是当每页的行数少于最大行数 (

我可以强制显示 Pager 行，但我需要隐藏第 1 页，因为很明显我们在 PAGE ONE 上！

                <asp:GridView ID="gvFTUNSENT" runat="server" 
                    AutoGenerateColumns="False" CellPadding="4" ForeColor="Black" AllowSorting="True" CssClass="gvCSS" Width="100%"
                    DataKeyNames="StudentID,StudentUnitID" DataSourceID="sdsFTUNSENT" 
                    GridLines="Vertical" AllowPaging="True" PageSize="10" BackColor="White" BorderColor="#DEDFDE" BorderStyle="None" BorderWidth="1px" 
                    OnPreRender="GridView_PreRender" 
                    OnLoad="GridView_Load" 
                    OnRowDataBound="GridView_RowDataBound" >
                    <RowStyle Wrap="True" Height="48px" />
                    <Columns>
...blahblah
                    </Columns>
                    <FooterStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
                    <PagerStyle CssClass="cssPager" BackColor="#6B696B" ForeColor="White" HorizontalAlign="Left" Height="100%" />
                    <HeaderStyle BackColor="#6B696B" Font-Bold="True" ForeColor="White" />
                    <EmptyDataTemplate>
                        <asp:Label ID="lblNDF1" runat="server" Text="NO DATA FOUND" Font-Size="X-Large" Width="500px" style="text-align:center" />
                    </EmptyDataTemplate>
                    <EmptyDataRowStyle HorizontalAlign="Center" />
                </asp:GridView>

这里我强制显示寻呼机行...

protected void GridView_PreRender(object sender, EventArgs e)
{
    GridView gv = (GridView)sender;

    //keep showing pager line even if there is only one row of data
    GridViewRow gvr = (GridViewRow)gv.BottomPagerRow;
    if (gvr != null)
        gvr.Visible = true;
}

但我不想在那里看到第 1 页，所以我尝试了这个...

if (e.Row.RowType == DataControlRowType.Pager)
{
    //keep showing pager line even if there is only one row of data
    GridViewRow gvr = (GridViewRow)e.Row;
    if (gvr != null)
    {
        gvr.Visible = true;

        //...but hide page number if there is only one page
        if (gv.PageCount == 1)
        {
            gv.ShowFooter = true;
            gv.PagerSettings.Visible = false;
        }
    }
}

但它实际上隐藏了整个 Pager 行！不！我只想隐藏页码。

ShowFooter 看起来像 gridview 是一个封闭的盒子。但它仍然很丑。如果我可以保持 Pager 行显示并能够隐藏其中的任何内容，我宁愿不使用它。即..保持背景颜色不变。

还有其他想法吗？谢谢

Answer 1

试试类似的东西

 protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
 {
    if (e.Row.RowType == DataControlRowType.Pager && GridView1.PageCount==1 )
    { e.Row.Style.Add("color", "white"); }
 }

或者，如果你不想处理颜色，你可以试试这个（但我认为它不太健壮）

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{

    if (e.Row.RowType == DataControlRowType.Pager && GridView1.PageCount==1 )
    {
        var a = e.Row.Controls;
        if (a.Count>0 && a[0] is TableCell)
        {
            var b = a[0].Controls[0].Controls[0] as TableRow;
            if (b != null)
            {
                //This is actually your page 1 text
                b.Cells[0].Text = "";
            }
         }
     }
}
