为什么我取不到txtNewValue 修改后的值，它显示的一直是从数据库邦定过来的值？请大虾指教。。

Answer 1

protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
            this.DataBindToGV();
    }    protected void DataBindToGV()
    {
        DataTable dt = new DataTable();
        dt.Columns.Add("StatusValue");
        dt.Columns.Add("isActive");
        dt.Columns[1].DataType = true.GetType();
        dt.Columns.Add("field1");
        dt.Columns.Add("field2");        dt.Rows.Add(new object[] { "aaaa",true,"awge","awgaw"});
        dt.Rows.Add(new object[] { "BBBB", false, "AGEGA", "AHW4H" });

    {
            TextBox txtNewValue = (TextBox)gvDocStatus.Rows[e.RowIndex].FindControl("txtEditStatus");
        TextBox1.Text = txtNewValue.Text;//这里可以取到txtNewValue修改后的值

to :Eddie005 ,对不起阿哥们，不好使啊，还是显示以前的值，没有取到更改的值。 :(

Answer 3

楼主，楼上的方法是对的，你debug下看看！是不是别的原因啊！

Answer 4

to: chengjun_java , 我知道 Eddie005的方法是正确的，我也是这么写的，可是我现在在debug环境下，看到的就是错误的信息。有点撞见鬼的感觉。 :(
请各位多帮帮忙吧

Answer 5

<asp:TextBox   ID="txtEditStatus"   runat="server"   Text=' <%#   Eval("StatusValue")   %> '   style="text-transform:none"> </asp:TextBox> !IsPostBack

Answer 6

to aqhuoqilin,<asp:TextBox       ID="txtEditStatus"       runat="server"       Text='   <%#       [color=#FF6600]Bind("StatusValue")       %>   '       style="text-transform:none">   </asp:TextBox>[/color] 
我现在是这么写的，可是还是捕捉不到更新的值，实在不知道什么地方出了问题，谁要是有高招，请多多指教，我实在是没有办法了。。

Answer 7

绑定数据的代码放到if(!IsPostBack){}里

Answer 8

to sq_zhuyi,
你实说这样吗？我是这样做的，有问题吗？请指教
protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                DataBindToGV();//绑定数据
            }
        }
