asp.net在Repeater嵌套的Repeater中使用复选框详解

.aspx文件中：

<%--顶层Repeater--%>

<asp:Repeater ID="rptChannel" runat="server">

<itemtemplate>

<br /><b><%# Eval("ChannelName")%></b>

<%--嵌套的Repeater,指定使用后台创建的Releation来获取数据源--%>

<asp:Repeater ID="rptClassify" DataSource='<%# Eval("myrelation") %>' runat="server">

<itemtemplate>

<input type="checkbox" id="chk_FlagID" value='<%# Eval("FlagID")%>' runat="server" />

<asp:Label ID="lbl_FlagName" runat="server" Text='<%# Eval("FlagName")%>'></asp:Label>

</itemtemplate>

</asp:Repeater >

<%--end 嵌套的Repeater,指定使用后台创建的Releation来获取数据源--%>

</itemtemplate>

</asp:Repeater >

<%--end 顶层Repeater--%>

.aspx.cs文件中：

#region Repeater嵌套的Repeater中使用复选框

//Repeater嵌套-经典运用

string sqlstr1, sqlstr2;

sqlstr1 =

"select distinct a.ChannelID,b.ChannelName from IE_FlagGroup a left join IE_Channel b on a.ChannelID=b.ChannelID where a.isClose=0 order by a.ChannelID asc"

;

sqlstr2 = "select * from IE_FlagGroup where isClose=0 order by FlagID asc";

DataSet dsChannel = DBFun.dataSetTwo(sqlstr1, "Channel", sqlstr2, "Classify", "myrelation");

dsChannel.Relations.Add("myrelation", dsChannel.Tables["Channel"].Columns["ChannelID"], dsChannel.Tables["Classify"].Columns["ChannelID"], false);

this.rptChannel.DataSource = dsChannel.Tables["Channel"];//绑定顶层Repeater（注意：只要绑定顶层就好，嵌套层不能绑定）

this.rptChannel.DataBind();

#endregion

//……略相关数据库操作代码

#region 设置Repeater嵌套的Repeater中相应的复选框为选中状态

string[] selTeamflag = drw["Teamflag"].ToString().Split(',');

HtmlInputCheckBox checkBox;

Repeater rpClass;

for (int i = 0; i < this.rptChannel.Items.Count; i++)

{

rpClass = (Repeater)this.rptChannel.Items[i].FindControl("rptClassify");

for (int j = 0; j < rpClass.Items.Count; j++)

{

checkBox = (HtmlInputCheckBox)rpClass.Items[j].FindControl("chk_FlagID");

if (selTeamflag.Contains(checkBox.Value))

checkBox.Checked = true;

}

#endregion

#region 获取Repeater嵌套的Repeater中的复选框所选择的值的组合,以","隔开

string str_Teamflag = "";

HtmlInputCheckBox checkBox;

Repeater rpClass;

for (int i = 0; i < this.rptChannel.Items.Count; i++)

{

rpClass = (Repeater)this.rptChannel.Items[i].FindControl("rptClassify");

for (int j = 0; j < rpClass.Items.Count; j++)

{

checkBox = (HtmlInputCheckBox)rpClass.Items[j].FindControl("chk_FlagID");

if (checkBox.Checked)

str_Teamflag += checkBox.Value + ",";

}

if (str_Teamflag != "")

{

//去除最后一个字符

//str_Teamflag = str_Teamflag.Substring(0, str_Teamflag.Length - 1);

str_Teamflag = str_Teamflag.Remove(str_Teamflag.Length - 1);

}

#endregion
