1、asp的checkbox和checkboxlist

cbl:http://heisetoufa.iteye.com/blog/293193

前台： 

<asp:CheckBoxList ID = "cblJL" runat = "server" RepeatDirection="Horizontal" Width="100%">
    <asp:ListItem>当前记录</asp:ListItem>
    <asp:ListItem>当前页</asp:ListItem>
    <asp:ListItem>全部记录</asp:ListItem>
</asp:CheckBoxList>

后台3种方式： 
第一种：获得CheckBox的值 

string save_cblJL = "";
for (int i = 0; i < this.cblJL.Items.Count; i++)
{
    if (this.cblJL.Items[i].Selected == true)
    {
        save_cblJL += this.cblJL.Items[i].Value + ",";
    }
}
Response.Write(save_cblJL);

第二种：获得CheckBox的值 

string str_Save_cblJL = "";
foreach (ListItem li in cblJL.Items)
{
    if (li.Selected == true)
    {
        str_Save_cblJL += li.Value + ",";
    }
}
Response.Write(str_Save_cblJL);

第三种：从后台给前台CheckBox赋值 

string strapp = "当前记录,当前页,全部记录,";
string[] strtemp = strapp.Split(',');
foreach (string str in strtemp)
{
    for (int i = 0; i < cblJL.Items.Count; i++)
    {
        if (this.cblJL.Items[i].Value == str)
        {
            this.cblJL.Items[i].Selected = true;
        }
    }
}
