如何取得Repeater控件选择的项目

Repeater控件，每个item前有一个CheckBox，把选择的item列显出来。

这个演法中，可以看到选择之后，该行highlight，此功能可以参考这个链接：http://www.cnblogs.com/insus/articles/1443165.html

下面是Repeater控件Html，有两个地方需要注意的，就是CheckBox与Label，这个Label是随你需要获取的内容而变化喔。如你想获取Nickname,那你需要把绑定的的内容放在Label上。

Repeater & CheckBox     <asp:Repeater ID="RepeaterEmailList" runat="server">
                                            <HeaderTemplate>
                                                <table border="1" cellpadding="1" cellspacing="0" width="96.5%">
                                                    <tr>
                                                        <td>
                                                        &nbsp;
                                                        </td>
                                                        <td>
                                                            Nickname
                                                        </td>
                                                        <td>
                                                            Email
                                                        </td>
                                                    </tr>
                                            </HeaderTemplate>
                                            <ItemTemplate>
                                                <tr style="height:10px; line-height:10px;">
                                                    <td>
                                                         <!--下面这个CheckBox的ID，注意喔，因为后台需要用到它-->
                                                        <asp:CheckBox ID="CheckBox1" runat="server" />
                                                    </td>
                                                    <td>
                                                        <%# Eval("nickname")%>
                                                    </td>
                                                    <td>
                                                       <!--下面这个Label的ID，注意喔，因为后台需要用到它-->
                                                        <asp:Label ID="Label1" runat="server" Text=' <%# Eval("mail")%>'></asp:Label>
                                                    </td>
                                                </tr>
                                            </ItemTemplate>
                                            <FooterTemplate>
                                                </table>
                                            </FooterTemplate>
                                        </asp:Repeater>

下面Insus.NET将会写一个方法，也许你的专案不止一个地方使用到，在需要的地方直接调用即可。

GetCheckBoxSelectedValue private string GetCheckBoxSelectedValue(Repeater repeater, string checkBoxId,string labelId)
    {
        string tempValue = string.Empty;

        foreach (RepeaterItem item in repeater.Items)
        {
            if (item.ItemType == ListItemType.Item || item.ItemType == ListItemType.AlternatingItem)
            {
                if (item.FindControl(checkBoxId) != null && item.FindControl(labelId) != null)
                {
                    CheckBox cb = (CheckBox)item.FindControl(checkBoxId);
                    Label lbl = (Label)item.FindControl(labelId);

                    if (cb.Checked)
                    {
                        tempValue = tempValue + ";" + lbl.Text;
                    }
                }              
            }
        }

        if (tempValue.Length > 0)
        {
            tempValue = tempValue.Substring(2);
        }

        return tempValue;
    }
