  • 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;
        }
