如果使用分页,如何获取辐射列表视图项目
本文关键字:获取 辐射 列表 项目 视图 分页 何获取 如果 | 更新日期: 2023-09-27 18:33:44
我在 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的问题。
例:
radlistview2.Items.ToList();
输出:我只有 10 个元素在第一页
我的问题是:
如何获取辐射列表中的所有项目 查看???
请尝试使用以下代码片段。
.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();
}
