在代码隐藏中构建一个表(包含行和列)(ASPX页面)

Question

在ASPX页面的代码隐藏中,我得到了关于员工的一些细节(从外部数据源读取).最后我想以下面的方式展示.下面的显示可能显示不正确,但是是带有标题/列方法的简化表.

___________________________________________________________________________________
|                        DEPT        | HR                                          | |__________________________________________________________________________________|
|     Employee Image                 | Emp Name       | Hire Date                  |
|____________________________________|_____________________________________________|
|        Steve.gif                   | Steve Jobs     |  22/05/1979                |
|____________________________________|_____________________________________________|
|        Mark.gif                    | Mark Miller    |  22/05/1949                |
|____________________________________|_____________________________________________|
|                        DEPT        | Operations                                  | |__________________________________________________________________________________|
|     Employee Image                 | Emp Name       | Hire Date                  |
|____________________________________|_____________________________________________|

数据从各种数据源收集,最终在代码隐藏中可用.我想以上述方式展示.

什么是最好的方法？我想创建一个htmldivcontrol并添加所有这些值.最后,我将div标签绑定到页面.

目前我正在尝试方法,但想知道是否有更好的方法.

请分享您的观点和示例._

在我看来,最好的方法是使用这样的Repeater:

<asp:Repeater ID="rpt" runat="server" OnItemDataBound="rpt_RowDataBound">
        <ItemTemplate>
            <table runat="server" style="color: White; background-color: #3A4F63;" visible="false"
                id="headerTable">
                <tr>
                    <td colspan="3" align="center">
                        <asp:Label ID="headerTitle" runat="server"></asp:Label>
                    </td>
                </tr>
                <tr>
                    <td style="width: 200px; background-color: #3A4F63; color: White;">
                        Image 
                    </td>
                    <td style="width: 200px;">
                        Name
                    </td>
                    <td style="width: 200px;">
                        Hire Date
                    </td>
                </tr>
            </table>
            <!-- These are the actual data items -->
            <!-- Bind to your specific properties i.e. Employees. -->
            <table>
                <tr>
                    <td style="width: 200px;">
                        <asp:Image ID="img" runat="server" ImageUrl='<%#Eval("ImageUrl") %>'></asp:Image>
                    </td>
                    <td style="width: 200px;">
                        <asp:Label ID="lblName" runat="server" Text='<%#Eval("Name") %>'></asp:Label>
                    </td>
                    <td style="width: 200px;">
                        <asp:Label ID="lblHireDate" runat="server" Text='<%#Eval("HireDate") %>'></asp:Label>
                    </td>
                </tr>
            </table>
        </ItemTemplate>
    </asp:Repeater>

然后在您的代码背后,类似于:

private string currentDepartment =string.Empty;

protected void rpt_RowDataBound(object sender, RepeaterItemEventArgs e)
{

    if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) {
        //Binding to Employee object.
        if (currentDepartment!= (e.Item.DataItem as Employee).Department) {
        currentDepartment = (e.Item.DataItem as Employee).Department;
            e.Item.FindControl("headerTable").Visible = true;
            (e.Item.FindControl("headerTitle") as Label).Text = (e.Item.DataItem as Employee).Department;
        }
            else {
            e.Item.FindControl("headerTable").Visible = false;
        }
    }
}

您将需要您的网格绑定到一个List<Employee>地方Employee会像这样定义:

public class Employee
{
   public string Department {get;set;}
   public string ImageUrl {get;set;}
   public DateTime HireDate {get;set;}
   public string Name {get;set;}
}

但是他们必须先被部门命令才能受到约束.

填充转发器的示例代码

private void bindGridView()
{
    List<Employee> emps = new List<Employee>();
    for (int i = 0; i < 5; i++)
    {
        Employee e = new Employee();
        if (i % 2 == 0)
        {
            e.Department = "Human resources";
            e.HireDate = DateTime.Now.AddDays(-i);
            e.ImageUrl = @"http://www.freedigitalphotos.net/images/gal_images/av-_146.jpg";
        }
        else
        {
            e.Department = "Information Technology";
            e.HireDate=DateTime.Now.AddMonths(-i);
            e.ImageUrl = "http://www.freedigitalphotos.net/images/gal_images/av-_314.jpg";

        }

        e.Name = "Employee " + i;
        emps.Add(e);

    }
    rpt.DataSource = emps.OrderBy(x=>x.Department);
    rpt.DataBind();
}
