【问题描述】：

我在我的 asp.net 项目中使用 radlistview。当我必须获取 radlistview 的所有项目时，它只返回当前页面的项目。

例子：

radlistview2.Items.ToList();

输出： 我只有第一页中的 10 个元素

我的问题是：

如何获取 radlistview 中的所有项目 ???

【参考方案1】：

请尝试以下代码 sn-p。

ASPX

<telerik:RadListView ID="RadListView1" runat="server" OnNeedDataSource="RadListView1_NeedDataSource" AllowPaging="true" PageSize="2">
            <ItemTemplate>
                <%# Eval("ID") %>
            </ItemTemplate>
        </telerik:RadListView>
        <telerik:RadDataPager ID="RadDataPager1" runat="server" PagedControlID="RadListView1"
            PageSize="2">
            <Fields>
                <telerik:RadDataPagerButtonField FieldType="FirstPrev"></telerik:RadDataPagerButtonField>
                <telerik:RadDataPagerButtonField FieldType="Numeric"></telerik:RadDataPagerButtonField>
                <telerik:RadDataPagerButtonField FieldType="NextLast"></telerik:RadDataPagerButtonField>
            </Fields>
        </telerik:RadDataPager>
        <asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />

ASPX.CS

protected void RadListView1_NeedDataSource(object sender, RadListViewNeedDataSourceEventArgs e)

    dynamic data1 = new[] 
           new  ID = 1, Name ="Name_1",Customdate = DateTime.Now,
           new  ID = 2, Name = "Name_2",Customdate = DateTime.Now,
           new  ID = 3, Name = "Name_3",Customdate = DateTime.Now,
           new  ID = 4, Name = "Name_4",Customdate = DateTime.Now,
           new  ID = 5, Name = "Name_5",Customdate = DateTime.Now
       ;
    RadListView1.DataSource = data1;

protected void Button1_Click(object sender, EventArgs e)

    int i = RadListView1.Items.Count();

    RadListView1.AllowPaging = false;
    RadListView1.Rebind();

    int j = RadListView1.Items.Count();
    //Access your count here

    RadListView1.AllowPaging = true;
    RadListView1.Rebind();
