Question

DataList中对CheckBox的遍历问题

string num = "";

foreach (DataListItem item in DataList1.Items)
{
System.Web.UI.WebControls.CheckBox chkExport;
chkExport = (CheckBox)item.FindControl("CheckBox1");

if (chkExport.Checked.Equals(true))
num += chkExport.Text;
else
num += "/";
//num += chkExport.Text;

//num += "*";
}

}
lblShow.Text += num;

页面回发，chkExport.Checked全是假。。。

怀疑你DataList在postback时重新绑定了. DataList1.DataBind()是否位于if (!IsPostBack)之内
