Question

我不知道我做错了什么，但我想做的是显示我们从数据库中检索的注册表数量，并将其显示在我们的页脚上，我们有“申请人总数:(这里我们应该是能够查看项目总数）“但我甚至无法调用asp：标签将其加载到.aspx.cs中。这是我的代码:(标签应该是lblTotal）

<blockquote>
        <asp:GridView ID="gvApplicants" runat="server" AllowPaging="True" AllowSorting="true"
            AutoGenerateColumns="False" DataKeyNames="Id" CellPadding="5" ForeColor="#333333" 
            GridLines="None" PageSize="10" ShowFooter="True" Width="100%"  Font-Size="9pt"
            OnSorting="gvApplicants_Sorting" OnPageIndexChanging="gvApplicants_PageIndexChanging">

            <Columns>
                <asp:BoundField DataField="Id" HeaderText="Id" ReadOnly="True" 
                    SortExpression="Id" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center" ItemStyle-VerticalAlign="Top" />
                <asp:TemplateField HeaderText="Complete Name" SortExpression="FirstName">
                    <HeaderStyle HorizontalAlign="Left" />
                    <ItemStyle HorizontalAlign="Left" VerticalAlign="Top" />
                    <ItemTemplate>
                        <a href='candidato.aspx?key=<%#Eval("Key")%>'>
                         <%# Eval("FirstName") %>
                         <%# Eval("MiddleName") %>
                         <%# Eval("LastName") %>
                         <%# Eval("SecondLastName") %></a>
                        <br />
                        <small><%# GetLabels(Eval("Id").ToString())%></small>
                    </ItemTemplate>
                    <FooterTemplate>
                        Total candidates: <asp:Label ID="lblTotal" runat="server"></asp:Label>
                    </FooterTemplate>
                </asp:TemplateField>

                <asp:TemplateField HeaderText="Vacancies" SortExpression="">
                    <HeaderStyle HorizontalAlign="Left" />
                    <ItemStyle HorizontalAlign="Left" />
                    <ItemTemplate>
                        <%# GetVacante(Eval("email").ToString())%>
                    </ItemTemplate>
                </asp:TemplateField>

                <asp:BoundField DataField="Status.Nombre" HeaderText="Status" 
                    SortExpression="Status.Nombre" HeaderStyle-HorizontalAlign="Left" ItemStyle-HorizontalAlign="Left"  ItemStyle-VerticalAlign="Top" />
                <asp:TemplateField HeaderText="Created Date" SortExpression="CreatedDate">
                <HeaderStyle HorizontalAlign="Left" />
                <ItemStyle HorizontalAlign="Left" VerticalAlign="Top" />
                    <ItemTemplate>
                        <asp:Label ID="Label1" runat="server" Text='<%#  Eval("createdDate", "{0:MMMM dd, yyyy. H:mm}") %>'></asp:Label>
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:BoundField DataField="Rating" HeaderText="Rating" SortExpression="Rating" HeaderStyle-HorizontalAlign="Left" ItemStyle-HorizontalAlign="Left" ItemStyle-VerticalAlign="Top"  />
            </Columns>

和.aspx.cs

private void LoadApplicants(Entity.Vacante v)
{
    try
    {
        ASF.HC.JobApplication.BO.User u = new BO.User();
        gvApplicants.DataSource = u.GetAllByVacancy(v);
        gvApplicants.DataBind();
        LoadData()

    }

    catch(Exception ex)
    {
        this.lblError.Text = "There was an unexpected error getting applicants: " + ex.Message;
    }
}
    protected void LoadTotal()
    {
        foreach (GridViewRow row in gvApplicants.Rows)
        {
            if (row.RowType == DataControlRowType.Footer)
            {
                Label myLabel = row.FindControl("lblTotal") as Label;
                if (myLabel != null)
                {
                    myLabel.Text = "hola";
                }
            }
        }
    }

你做错了什么。您仍在使用网络表单。只是开玩笑，问题是你无法像其他控件那样使用id访问模板文件中的控件。你需要做这样的事情。

foreach(GridViewRow row in myGridView.Rows) {
    if(row.RowType == DataControlRowType.Footer) {
        Label myLabel= row.FindControl("myLabelId") as Label;
        if(myLabel!=null)
        {
         //Do your stuff
        }   
    }
}

FooterTemplate无法调用我的.aspx.cs中的任何函数
