在对象列表隐藏附加属性被绑定到一个gridview [英] Hiding Additional Attributes in a list of objects to be binded to a gridview

问题描述

我有型的用户现场负载有许多属性，我想隐藏一些属性，因为我不希望我的网格视图显示所有这些对象的列表。

I have a list of objects of type user site load that has many attributes , i want to hide some of these attributes because i do not want My grid view to show all of these.

我该怎么办呢？我使用 GridView.DataSource = MyListOfUserSiteLoadObjects;

How can i do it? I use GridView.DataSource=MyListOfUserSiteLoadObjects;

public partial class Create : System.Web.UI.Page
{
    public List<Entity.UserSiteLoad> MyTempList = new List<Entity.UserSiteLoad>();
    public Entity.UserSiteLoad usl = new Entity.UserSiteLoad();
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            Session["MyApplianceList"] = MyTempList;  
        }


    }

    protected void BtnAddNext_Click(object sender, EventArgs e)
    {
        List<Entity.UserSiteLoad> LstUsl = (List<Entity.UserSiteLoad>)Session["MyApplianceList"];
        usl.Applianc = new Entity.Appliance();
        usl.Applianc.Name = DDLAppName.Text;
        usl.Quantity = Convert.ToInt32(QtyTB.Text);
        usl.DayTime = Convert.ToInt32(DayTymTB.Text);
        usl.BackUpTime = Convert.ToInt32(BackUpTymTB.Text);
        if (LstUsl.Count != 0)
        {
            for (int rowIndex = 0; rowIndex < LstUsl.Count; rowIndex++)
            {
                string AppName = LstUsl[rowIndex].Applianc.Name;
                if (AppName == DDLAppName.Text)
                {
                    LstUsl.Remove(LstUsl[rowIndex]);
                }

            }
        }
        if (LstUsl.Count == 0 || LstUsl.Count > 0)
        {
            LstUsl.Add(usl);
        }



        AllItems.DataSource = LstUsl;
        AllItems.DataBind();
        AllItems.Visible = true;
        Response.Write("It has: " + AllItems.Attributes.Count);


    }
}

第二个问题：我要一列添加到我的 GridView控件名为设备名称并将其值设置为 USL .Applianc.Name Applianc 里面聚集对象的用户站点的负载对象

2nd problem: I want to add a column to my GridView named "Appliance name" and set its value to usl.Applianc.Name , Applianc is an aggregated object inside user site load object.

这怎么可能？

推荐答案

您应该配置的AutoGenerateColumns 的属性＆LT; ASP：GridView的/方式＆gt; 元素假和配置/手动绑定列

You should configure the AutoGenerateColumns property of the <asp:GridView /> element to false and configure/bind the columns manually.

下面的堆栈会给你如何做到这一点的想法：

The following stack will give you an idea of how to do that:

手动将数据绑定到的GridView

显然，你应该和可以绑定自己的集合到数据源属性。

Obviously you should and can bind your own collections to the DataSource property.

我觉得你的code，后面可以保持原样，你只需要改变一些标记：

I think your code-behind can stay as is and you only have to change some markup:

<asp:GridView ID="AllItems" runat="server" AutoGenerateColumns="false">
    <Columns>
        <asp:BoundField DataField="PropA" HeaderText="Property A" />
        <asp:BoundField DataField="PropB" HeaderText="Property B" />
        <!-- ... -->
    </Columns>
</asp:GridView>
