★★★GridView控件问题!!!!在线等到死!!!!!★★★分就剩这么多了..对不住了..

Question

public partial class management_EsseyDU : System.Web.UI.Page
{
    private int pn;
    protected void Page_Load(object sender, EventArgs e)
    {
        string pns = Request.QueryString["pno"];
        if (pns == null) pn = 0;
        else pn = Convert.ToInt32(pns);
        atcllist.PageIndex = pn;
        EsseyOperator eop = new EsseyOperator();
        atcllist.DataSource = eop.DisplayList();
        atcllist.DataBind();
        eop.ConnFree();
    }//atcllist是一个GridView控件~~
//eop.DisplayList()的返回值是一个DataView...
//显示的时候全是正常的..就是下面这个出问题!!!    protected void atcllist_RowDeleting(object sender, GridViewDeleteEventArgs e)
    {
        Response.Write(atcllist.Rows[e.RowIndex].Cells[0].Text == ""? "EMPTY" : "NOT");
    }
}为什么atcllist.Rows[e.RowIndex].Cells[0].Text 老是""呢??
显示都是正常的啊..其它操作也都正常~~
上面输不出来..想删数据就不好干啊..atcllist.Rows[e.RowIndex].Cells.Count 输出的时候为 2...atcllist.Rows[e.RowIndex].Cells[1].Text 也是 ""e.Keys.Count.ToString() 输出为 0e.Values.Count.ToString() 输出为 0这是怎么回事啊..搞不懂了..搞了好久都没搞通...DX们 救人啊啊啊啊啊!!!!!~~

Answer 1

protected void atcllist_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
string str = atcllist.Rows[e.RowIndex].Cells[0].Text.Trim();
this.Response.Write("<script>alert('"+str+"');</script>");
//.................................
}
//看看str是什么

Answer 5

AutoGenerateColumns="true"的时候就可以了...
但是我现在想自定义格式啊..
就不行了...
