Question

我有一个gridview，我需要分页。当我allowPaging = true时，它显示145678910 ....它不会显示第2页和第3页。如果我尝试将模式更改为NextPreviousFirstLast，它只在第一页上显示'Next'，如果我点击它，它只在第二页上显示“第一个”和“最后一个”。这是代码：

<asp:GridView ID="GridView1" runat="server" CellPadding="4" ForeColor="Black" AutoGenerateColumns="False" BackColor="#CCCCCC" 
            BorderColor="#666666"    OnRowDataBound  = "HandleRowDataBound" BorderStyle="Solid" BorderWidth="1px" CellSpacing="2" Width ="942px"
            Font-Names="Arial" Font-Size="8pt" ShowHeaderWhenEmpty="True"  CSSClass="mytable" AllowPaging="true" OnPageIndexChanging="GridView1_PageIndexChanging"

以下是代码：

protected void Page_Load(object sender, EventArgs e)
    {

        siteID = int.Parse(Request.QueryString["s"].ToString());
        FillDetails(); 
    }

    //Pulls data from database for items to be recalled based on site, and user rights and enables to functions of the controls 
    private void FillDetails()
    {
        DataSet materials = RequestDB2.GetStoredMaterialsView(siteID);

        GridView1.DataSource = materials;
        GridView1.DataBind();

        if (GridView1.Rows.Count >= 9) 
            paneling.Style["height"] = "300px";
        //if not items exit
        if (materials == null || materials.Tables[0].Rows.Count == 0)
        {
            Error.InnerText = "You have no materials to be recalled from this site.";
        }
        else
        {
            //Adds thead and tbody tags
            GridView1.HeaderRow.TableSection = TableRowSection.TableHeader;
        }
    }

    protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
    {
        GridView1.PageIndex = e.NewPageIndex;
        GridView1.DataBind();
    }


    protected void HandleRowDataBound(object sender, GridViewRowEventArgs e)
    {

    }

以下是我看到的内容： enter image description here

当我看到萤火虫时，我看到第2页和第3页显示：无。关于为什么会发生这种情况的想法？

Answer 1

您没有在GridView1_PageIndexChanging中分配数据源。您需要在绑定之前分配数据源。你最好试着调用FillDetails（）变化

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
    GridView1.PageIndex = e.NewPageIndex;
    GridView1.DataBind();
}

要

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
    GridView1.PageIndex = e.NewPageIndex;
    FillDetails();       
}

Answer 2

尝试使用PagerSetting作为..

   <PagerSettings  FirstPageText="First Page"  LastPageText="Last Page" 
                   Mode="NumericFirstLast" Position="TopAndBottom" />  

protected void grdView_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
    GridView1.DataSource  = RequestDB2.GetStoredMaterialsView(siteID);
    GridView1.PageIndex = e.NewPageIndex;
    GridView1.DataBind();
}

GridView allowPaging = true不显示页码2和3.显示14567
