Answer 1

给GridView绑定数据的代码放在Page_Load的
if(!IsPostBack)
{}
中

Answer 2

不是写了吗
protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                ViewState["tb"] = speList;
                FillGrid();
            }        }

Answer 3

已绑定
FillGrid()就是绑定数据
关键是编辑时文本框的数据都没有取出来

Answer 4

你在rowcommand时只判断了insert，所以更新之前又重新绑定了，你检查下

Answer 5

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
        {
            if (e.CommandName.Equals("Insert"))
            {
                //int id = 0;
                TextBox txtNewSpecimenName = (TextBox)GridView1.FooterRow.FindControl("txtNewSpecimenName");
                TextBox txtNewSpecimenDesc = (TextBox)GridView1.FooterRow.FindControl("txtNewSpecimenDesc");
                ((List<PIS.Model.TEST_SPECIMEN>)ViewState["tb"]).Add(new PIS.Model.TEST_SPECIMEN(0, 0, txtNewSpecimenName.Text, txtNewSpecimenDesc.Text, null, DateTime.Now));
                //((List<PIS.Model.TEST_SPECIMEN>)ViewState["tb"]).Add(new PIS.Model.TEST_SPECIMEN(1, GridView1.Rows.Count + 1, txtNewSpecimenName.Text, txtNewSpecimenDesc.Text, null, DateTime.Now));
                               
            }
            FillGrid();        }这是你的rowcommand，你调试下看看，是不是重新绑定了

Answer 6

你最牛。是你说的这个问题。哈哈
我把FillGrid();放在if（e.CommandName.Equals("Insert"))里面了。问题解决了。感谢。结贴了。
