Question

我正在开发一个公司网络应用程序。

我的ASP .NET GridView工作正常，但我不知道我做了什么改变使它停止显示行。它只显示一行或根本没有行。

这是我的代码：

private void BindAnnualLeaveGrid() 
{
    try {
        string s = (string)Session["Status"];
        if (s == null)
            s = "Approved";
        Employee emp = (Employee)Session["Employee"];
        DataTable table = DataAccess.GetLeave("Annual", s, emp.Id);
        this.gvUserAnnualLeave.DataSource = table;
        this.gvUserAnnualLeave.DataBind();
        Debug.WriteLine("this.gvUserAnnualLeave.Rows.Count=" + this.gvUserAnnualLeave.Rows.Count);
    } catch (Exception ex) {
        Debug.WriteLine(ex.StackTrace);
    }
}

Debug.WriteLine行（＆＃34; this.gvUserAnnualLeave.Rows.Count =＆＃34; + this.gvUserAnnualLeave.Rows.Count）;打印4行，所以在DATATABLE中有行。

任何帮助都将不胜感激。

这是ASPX代码：

 <asp:Table ID="Table5" runat="server" Width="100%">
                <asp:TableRow>
                    <asp:TableCell>
                        <asp:Label ID="Label1" runat="server" Text="Annual Leave Summary" Font-Size="Small" ForeColor="#022439"></asp:Label>
                    </asp:TableCell>

                <asp:TableRow>

                            <EmptyDataTemplate>
                                No Data To Display!
                            </EmptyDataTemplate>
                        </asp:GridView>
                    </asp:TableCell>
                </asp:TableRow>
            </asp:Table>
