Coding:btton事件里面:
string[] Upload_ID=(string[])ViewState["Ckb_SelectedData"];
SqlDataAdapter sqldata=new SqlDataAdapter();
int CheckCount=0;
sqldata=upload.BindDataList(0,1,1); //需要修改 
string err="";



foreach(DataListItem CheckBoxItem in this.DL_Info.Items)
{

CheckBox cb=(CheckBox)CheckBoxItem.FindControl("Ckb_SelectedData");                
if (cb.Checked)
{
CheckCount++;

}
for(int i=0;i<CheckCount;i++)
{
err=upload.PassUpload(int.Parse(Upload_ID[i].ToString()),sqldata);
}
