. cs中的代码：
baseclass bc=new baseclass() ;
protected void DataList1_ItemCommand(object source, DataListCommandEventArgs e)
    {
        Response.Write(bc.messagebox("fffff"));
        if (e.CommandArgument != null)
        {
            int intID = Convert.ToInt32(e.CommandArgument);            bc.execsql("update [file] set examine='已接收' where fileid='" + intID.ToString() + "'");
            DataList1.DataSource = bc.getdataset("select * from [file] where examine='已接收' order by filetime desc", "file");
            DataList1.DataKeyField = "fileid";
            DataList1.DataBind();
        }
    }

解决方案 »

  1.   

    是不是页面刷新了？在load函数中添加if(!IsPostBack){
    //你的代码
    }试一下
      

  2.   

    protected void Page_Load(object sender, EventArgs e)
        {
            if (！IsPostBack)
            {
                DataList1 .DataSource =bc.getdataset ("select * from [file] where examine='已接收' order by filetime desc","file");
                DataList1.DataKeyField = "fileid";
                DataList1.DataBind();        }
            if (显示未接收.Checked)
            {
                DataList1.DataSource = bc.getdataset("select * from [file] where examine='未接收' order by filetime desc", "file");
                DataList1.DataKeyField = "fileid";
                DataList1.DataBind();
            }
            if (显示已接收.Checked)
            {
                DataList1.DataSource = bc.getdataset("select * from [file] where examine='已接收' order by filetime desc", "file");
                DataList1.DataKeyField = "fileid";
                DataList1.DataBind();
            }
        }
        
    我的LOAD代码中有的，还是不行啊！！！！！！！！！！
      

  3.   

    你的bc.execsql测试过了吗？把button换成linkButton试一下。
