如何根据字符串选定CheckBoxList值
有字符串"1.0,2.0,2.1,”
如何选定

  <asp:CheckBoxList ID="cblRcdr" runat="server" RepeatDirection="Horizontal">
  <asp:ListItem Value="1.0">浏览</asp:ListItem>
  <asp:ListItem Value="1.1">增加</asp:ListItem>
  <asp:ListItem Value="1.2">修改</asp:ListItem>
  <asp:ListItem Value="1.3">删除</asp:ListItem>
  </asp:CheckBoxList>

  <asp:CheckBoxList ID="cblRcdrRecord" runat="server" RepeatDirection="Horizontal">
  <asp:ListItem Value="2.0">浏览</asp:ListItem>
  <asp:ListItem Value="2.1">增加</asp:ListItem>
  <asp:ListItem Value="2.2">修改</asp:ListItem>
  <asp:ListItem Value="2.3">删除</asp:ListItem>
  </asp:CheckBoxList>

------解决方案--------------------
ListItem x = cblRcdr.Items.FindByValue("1.2");
if(x!=null) x.Selected=true;
------解决方案--------------------
1.0,2.0,2.1,

Split循环即可
