我正在使用Repeater来显示来自Web服务的一些数据。
我的中继器结构是:
<asp:Repeater ID="rptgrp" runat="server">
<ItemTemplate>
<asp:CheckBoxList ID="chkBoxListGoup" runat="server"
DataSource='<%# DataBinder.Eval(Container.DataItem, "Titles")%>'
DataTextField="Title"
DataValueField="IDTitle">
</asp:CheckBoxList>
</ItemTemplate>
</asp:Repeater>
现在,我的网络服务会在“标题”中返回这些字段:
1)标题
2)IDTitle
3)isUserTitle
现在,我想在isUserTitle = 1时设置一个复选框。
我该怎么做?

您可以在下面找到复选框列表
在itemdatabound中查找复选框列表, 使用循环检查每个checkboxlist的项目文本, 选择文本为1
的项目Protected void Repeater_ItemDataBound(Object Sender, RepeaterItemEventArgs e) {
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
CheckBoxList chklst = (CheckBoxList)e.Item.FindControl("chkBoxListGoup");
for (int i = 0; i < chk.Items.Count; i++)
{
if (chk.Items[i].Text == "1")
{
chk.Items[i].Selected = true;
}
}
}
}

尝试更改<asp:CheckBoxList ID="chkBoxListGoup" runat="server"
到
<asp:CheckBoxList ID="chkBoxListGoup" Checked='<%#Eval("Flag")%>' runat="server"
Flag是你的专栏..
然后在你的方法或事件处理程序中,你想运行一些代码来说明是否检查了这个值= 1,elseif value = 0 unchecked ...

以下是演示该想法的示例代码:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web.UI.WebControls;
using WebApp.RepeaterCheckboxList.TODODatasetTableAdapters;
namespace WebApp.RepeaterCheckboxList
{
public partial class WebForm1 : System.Web.UI.Page
{
IEnumerable<TODODataset.TasksViewRow> view;
IEnumerable<TODODataset.TasksViewRow> subview;
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
TasksViewTableAdapter adp = new TasksViewTableAdapter();
var dt = adp.GetData();
view = dt.AsEnumerable();
var names = (from x in view
select new
{
Person = x.Name,
ID = x.PersonID
}).Distinct();
DataList1.DataSource = names;
DataList1.DataBind();
}
}
protected void CheckBoxList1_DataBound(object sender, EventArgs e)
{
CheckBoxList theList = (CheckBoxList)sender;
var person = ((DataListItem)theList.Parent).DataItem as dynamic;
var name = person.Person;
var id = person.ID;
var vw = subview;
for (int i = 0, j = vw.Count(); i < j; i++)
{
var task = vw.ElementAt(i);
theList.Items[i].Selected = task.Completed;
}
}
protected IEnumerable<TODODataset.TasksViewRow> GetTasks(object data)
{
var vw = data as dynamic;
return subview = (from x in view
where x.PersonID == vw.ID
select x);
}
}
}

尝试将Checked
值设置为Eval
编辑的对象。
<asp:Repeater ID="rptgrp" runat="server">
<ItemTemplate>
<asp:CheckBoxList ID="chkBoxListGoup" runat="server"
Checked=<%# Eval("isUserTitle") %>>
</asp:CheckBoxList>
</ItemTemplate>
</asp:Repeater>
