取得GridView中的文本框更新后的值（VB.NET）

实在是郁闷，搞了好半天才搞出来，原来，就差在Page_Load里面没加上 If (Not Page.IsPostBack) Then

后台代码：

  Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        If (Not Page.IsPostBack) Then

            DataBind()

        End If

    End Sub

 

    Protected Sub gvBS_RowUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewUpdateEventArgs) Handles gvCompany.RowUpdating

        Dim cID As String
        Dim cName As String

        Dim r As Integer
        r = e.RowIndex

        cID = CType(gvBS.Rows(r).Cells(0).FindControl("lblID"), Label).Text

        cName = CType(gvBS.Rows(r).Cells(1).FindControl("txtName"), TextBox).Text

    End Sub

 前台代码：

<asp:GridView runat="server" AutoGenerateColumns="False" >
                                <Columns>
                                    <asp:TemplateField HeaderText="ID">
                                        <EditItemTemplate>
                                            <asp:Label ID="lblID" runat="server" Text='<%# Eval("id") %>'></asp:Label>
                                        </EditItemTemplate>
                                        <ItemTemplate>
                                            <asp:Label ID="lblID2" runat="server" Text='<%# Bind("id") %>'></asp:Label>
                                        </ItemTemplate>
                                    </asp:TemplateField>
                                    <asp:TemplateField HeaderText="名称">
                                        <EditItemTemplate>
                                            <asp:TextBox ID="txtName" runat="server" Text='<%# Bind("name") %>' MaxLength="50"></asp:TextBox>
                                        </EditItemTemplate>
                                        <ItemTemplate>
                                            <asp:Label ID="lblName" runat="server" Text='<%# Bind("name") %>' ></asp:Label>
                                        </ItemTemplate>
                                    </asp:TemplateField>
                                </Columns>
                            </asp:GridView>
