在我的项目中Repeater Control
运行正常。现在我需要分页来替换这些数据。但我没有任何关于此的信息。可能有人就这个问题给我建议。
如下图所示。

Repeater控件中没有内置分页,但基于this文章,您可以通过为页面创建另一个Repeater控件并使用PagedDataSource
作为源来实现Repeater控件中的分页。
首先,将其添加到您的标记中:
<div style="overflow: hidden;">
<asp:Repeater ID="rptPaging" runat="server" OnItemCommand="rptPaging_ItemCommand">
<ItemTemplate>
<asp:LinkButton ID="btnPage"
style="padding:8px;margin:2px;background:#ffa100;border:solid 1px #666;font:8pt tahoma;"
CommandName="Page" CommandArgument="<%# Container.DataItem %>"
runat="server" ForeColor="White" Font-Bold="True">
<%# Container.DataItem %>
</asp:LinkButton>
</ItemTemplate>
</asp:Repeater>
</div>
接下来,在您的代码中添加以下属性:
//This property will contain the current page number
public int PageNumber
{
get
{
if (ViewState["PageNumber"] != null)
{
return Convert.ToInt32(ViewState["PageNumber"]);
}
else
{
return 0;
}
}
set { ViewState["PageNumber"] = value; }
}
最后添加以下方法:
protected void Page_Load(object sender, EventArgs e)
{
BindRepeater();
}
private void BindRepeater()
{
//Do your database connection stuff and get your data
SqlConnection cn = new SqlConnection(yourConnectionString);
SqlCommand cmd = new SqlCommand();
cmd.Connection = cn;
SqlDataAdapter ad = new SqlDataAdapter(cmd);
cmd.CommandText = "Select * from YourTable";
//save the result in data table
DataTable dt = new DataTable();
ad.SelectCommand = cmd;
ad.Fill(dt);
//Create the PagedDataSource that will be used in paging
PagedDataSource pgitems = new PagedDataSource();
pgitems.DataSource = dt.DefaultView;
pgitems.AllowPaging = true;
//Control page size from here
pgitems.PageSize = 4;
pgitems.CurrentPageIndex = PageNumber;
if (pgitems.PageCount > 1)
{
rptPaging.Visible = true;
ArrayList pages = new ArrayList();
for (int i = 0; i <= pgitems.PageCount - 1; i++)
{
pages.Add((i + 1).ToString());
}
rptPaging.DataSource = pages;
rptPaging.DataBind();
}
else
{
rptPaging.Visible = false;
}
//Finally, set the datasource of the repeater
RepCourse.DataSource = pgitems;
RepCourse.DataBind();
}
//This method will fire when clicking on the page no link from the pager repeater
protected void rptPaging_ItemCommand(object source, System.Web.UI.WebControls.RepeaterCommandEventArgs e)
{
PageNumber = Convert.ToInt32(e.CommandArgument) - 1;
BindRepeater();
}
请试一试,如果您遇到任何问题,请告知我。
编辑:替代解决方案
可以找到另一个出色的解决方案Here,此解决方案包括页面的导航按钮。您需要从该链接下载文件才能看到功能分页,只需用您的Repeater控件替换DataList控件。
希望这有帮助。
