GridView1_RowUpdating事件为什么取不到编辑状态下的值啊?

Question

前台代码:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="AlbumID" BorderWidth="0px" OnRowCancelingEdit="GridView1_RowCancelingEdit" OnRowEditing="GridView1_RowEditing" OnRowUpdating="GridView1_RowUpdating">

                            </asp:CommandField>
                        </Columns>
                    </asp:GridView>
后台代码:
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
    {
        //DropDownList ddl = this.GridView1.Rows[e.RowIndex].FindControl("DropDownList1") as DropDownList;
        //string stars = ddl.SelectedItem.Value.ToString();
        string stars = ((DropDownList)GridView1.Rows[e.RowIndex].Cells[7].FindControl("DropDownList1")).SelectedItem.Value.ToString();        CheckBox cb1 = this.GridView1.Rows[e.RowIndex].Cells[5].Controls[0] as CheckBox;
        CheckBox cb2 = this.GridView1.Rows[e.RowIndex].Cells[6].Controls[0] as CheckBox;
        int hot = 0;
        int elite = 0;
        if (cb1.Checked)
            elite = 1;
        if (cb2.Checked)
            hot = 1;
        CM_Video_Album aAlbum = new CM_Video_Album();
        aAlbum.IsHot = hot;
        aAlbum.IsElite = elite;
        aAlbum.Stars = Convert.ToInt32(stars);
        aAlbum.AlbumID = Convert.ToInt32(this.GridView1.DataKeys[e.RowIndex].Value.ToString());
        cvam.Update_Album(aAlbum);
        this.GridView1.EditIndex = -1;
        string userName = "";
        string albumTime = "";
        if (ViewState["UserName"] != null)
        {
            userName = ViewState["UserName"].ToString();
        }
        if (ViewState["AlbumName"] != null)
        {
            albumTime = ViewState["AlbumName"].ToString();
        }
        BindPage(albumTime, userName);
另外GridView1_RowEditing和GridView1_RowCancelingEdit事件都写了,问题是编辑状态下,DropDownList1和两个CheckBoxField都取不到值,DropDownList1一直是0,CheckBoxField的checked一直false,即使你选中!
真是奇怪啊!以前一直可以的啊!高手帮忙!

Answer 1

检查一下aspx页顶部或者web.config里有没有设置enableViewStates = false
