c# - 将自定义对象数据绑定到 aspx 文件中的控件而不是隐藏代码

Question

我在完全绑定 aspx 文件中的通用列表时遇到问题。虽然它正确绑定到我的<p>和<h>标签，但不是我的 ImageButton。我在这里做错了什么。下面是我的代码

.aspx 文件

<%
int count = 1;
for (item = 0; item < mList.Count; AddItem())
{
   if (count == 3)
{ %>
<div class="one_third_last">
        <% count = 0;
            }
            else
            { %>
        <div class="one_third">
            <%}
            count++;%>
            <div class="modern_img_frame modern_four_col_large">
                <div class="preload_four_col_large">
                    <div class="attachment-fadeIn">
                        <asp:ImageButton ID="ImageButton" runat="server" ImageUrl="~/images2/premium-website-template-2.jpg"
                            ToolTip="CSS Template" AlternateText="CSS Template" Width="190" Height="111"
                            CommandName="<%# mList[item].PaymentCode %>" CommandArgument="<%# mList[item].PaymentDescription %>"
                            OnCommand="ImageButton_Command" />
                    </div>
                </div>
            </div>
            <!-- end modern_img_frame -->
            <h6>
                <%= mList[item].PaymentDescription%></h6>
            <p>
                <%= mList[item].PaymentDescription%></p>
        </div>
        <% 
}  %>

代码背后

protected List<Payments_Default> mList;
protected int item;
public String PaymentCode { get; set; }
public String PaymentDescription { get; set; }
public int PaymentNumber { get; set; }

protected void Page_Load(object sender, EventArgs e)
{       

    mList = new Payments_Default().GetPaymentTypes();
    this.DataBind();
}

protected void AddItem()
{
    item++;
}

protected List<Payments_Default> GetPaymentTypes()
{
    List<Payments_Default> mList = new List<Payments_Default>();
    Payments_Default mObject = null;

    SqlCommand command = GenericSqlDataAccess.CreateCommandOnline("Text");
    command.CommandText = "SELECT bla bla bla";

    DataTable table = new DataTable();
    table = GenericSqlDataAccess.ExecuteReader(command);

    foreach (DataRow row in table.Rows)
    {
        mObject = new Payments_Default();
        mObject.PaymentCode = row["PayTypeCode"].ToString();
        mObject.PaymentDescription = row["PayTypeDesc"].ToString();
        mObject.PaymentNumber = table.Rows.Count;
        mList.Add(mObject);
    }

    return mList;
}
