checkboxlist是复选框的集合，对checkboxlist赋值是没有意义的，要对里面的选

项赋值
checkboxlist1.items.add(new listitem("文本1", "value1"));
checkboxlist1.items.add(new listitem("文本2", "value2"));

核心代码

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;
  }
}
}
