当用户在编辑模板中更改文本框中的文本并单击更新时，当我尝试获取这些新值时，它仍然是文本框的旧值。

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 
        DataKeyNames="CompanyID" CellPadding="4"  
        GridLines="None" Width="1079px" ForeColor="#333333" 
        OnRowCancelingEdit="GridView1_RowCancelling"
        OnRowUpdating="GridView1_RowUpdating"
        OnRowEditing="GridView1_RowEditing">


        <AlternatingRowStyle BackColor="White" ForeColor="#284775" />
        <Columns>
            <asp:TemplateField ShowHeader="False">

                <EditItemTemplate>
                    <asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="True" 
                        CommandName="Update" CommandArgument='<%# Eval("CompanyID") %>' Text="Update"></asp:LinkButton>

                        CommandName="Edit" Text="Edit" ></asp:LinkButton>
                </ItemTemplate>


            </asp:TemplateField>



            <asp:TemplateField HeaderText="Issue Date">

                <ItemTemplate>
                    <asp:Label runat="server" ID="IssueDate" Text='<%#Eval("IssueDate") %>' />

            <asp:TemplateField HeaderText="Notice Intent Response Due">

                <ItemTemplate>

            </asp:TemplateField>


            <asp:TemplateField HeaderText="Shortlist Notice">

                </ItemTemplate>

                <EditItemTemplate>
                    <asp:TextBox runat="server" ID="txtFinalSelection" Text='<%#Eval("FinalSelection") %>' />
                </EditItemTemplate>

            </asp:TemplateField>





            <asp:TemplateField Visible="false" HeaderText="CompanyID">

                <ItemTemplate>
                    <asp:Label runat="server" ID="CompanyID" Text='<%#Eval("CompanyID") %>' />
                </ItemTemplate>

            </asp:TemplateField>




        </Columns>



    </asp:GridView>

更新按钮调用此函数：

protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)

    {

        int key = Convert.ToInt32(GridView1.DataKeys[e.RowIndex].Value);

        Label CompanyID = (Label)GridView1.Rows[e.RowIndex].FindControl("txtCompanyID");

        TextBox thisIssueDate = (TextBox)(GridView1.Rows[e.RowIndex].FindControl("txtIssueDate"));

        TextBox NoticeIntentResponseDue = (TextBox)GridView1.Rows[e.RowIndex].FindControl("txtNoticeIntentResponseDue");

        Response.Write(NoticeIntentResponseDue.Text + " " + thisIssueDate.Text);
        Response.End();

        TextBox DeadlineForQuestions = (TextBox)GridView1.Rows[e.RowIndex].FindControl("txtDeadlineForQuestions");

        TextBox BidsDue = (TextBox)GridView1.Rows[e.RowIndex].FindControl("txtBidsDue");

        TextBox ShortlistNotice = (TextBox)GridView1.Rows[e.RowIndex].FindControl("txtShortlistNotice");

        TextBox FinalSelection = (TextBox)GridView1.Rows[e.RowIndex].FindControl("txtFinalSelection");
    }

响应向我显示，被抓取的值仍然是框的原始文本值。不是您在框中键入的内容。

在您的网格视图行更新事件中添加以下条件

protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
 if (e.Row.RowState == DataControlRowState.Edit )
 {


    int key = Convert.ToInt32(GridView1.DataKeys[e.RowIndex].Value);

    Label CompanyID = (Label)GridView1.Rows[e.RowIndex].FindControl("txtCompanyID");

    TextBox thisIssueDate = (TextBox)(GridView1.Rows[e.RowIndex].FindControl("txtIssueDate"));

    TextBox NoticeIntentResponseDue = (TextBox)GridView1.Rows[e.RowIndex].FindControl("txtNoticeIntentResponseDue");

    Response.Write(NoticeIntentResponseDue.Text + " " + thisIssueDate.Text);
    Response.End();

    TextBox DeadlineForQuestions = (TextBox)GridView1.Rows[e.RowIndex].FindControl("txtDeadlineForQuestions");

    TextBox BidsDue = (TextBox)GridView1.Rows[e.RowIndex].FindControl("txtBidsDue");

    TextBox ShortlistNotice = (TextBox)GridView1.Rows[e.RowIndex].FindControl("txtShortlistNotice");

    TextBox FinalSelection = (TextBox)GridView1.Rows[e.RowIndex].FindControl("txtFinalSelection");
    }  
  }

更新：问题看起来您还绑定了您的编辑项模板列与数据表中的数据，当您在后面的代码中获取数据时，您没有获得用户在编辑模式下更新的更新数据仍在获取旧数据。If you remove the Binding from the Edit Item Template feilds then your code will work.

我想通了，德里克是对的。它与页面加载中回发的绑定数据有关。我每次都绑定数据，而不仅仅是第一次。谢谢
