推荐答案

您好，在您的代码隐藏中，将数据绑定到DatailsView之后，您可以创建一个新的模板字段，然后将其添加到DetailsView中:

Hello, in your code-behind, after the databind to you DatailsView you can create a new template field, then add it to the DetailsView:

TemplateField TheTF = new TemplateField();
TheDetailsView.Fields.Add(TheTF);
TheTF.ItemTemplate = AddTemplate(ListItemType.Item);
//Rebind after creation of itemtemplate.
TheDetailsView.DataBind()

您不能直接在TemplateFields中添加项目，例如，您需要创建一个模板(该模板继承自ITemplate):

You can''t add items directly in the TemplateFields, se you need to create a template (That inherits from ITemplate):

public class AddTemplate : ITemplate
{
    private ListItemType m_ListItemType;
    public AddTemplate(ListItemType _listItemType)
    {
        m_ListItemType = _listItemType;
    }

    public void InstantiateIn(System.Web.UI.Control container)
    {
        if (m_ListItemType == ListItemType.Item)
        {
            TextBox TheIDTb = new TextBox();
            TheIDTb.DataBinding += new EventHandler(TheIDTb_DataBinding);
            container.Controls.Add(TheIDTb);
        }
    }

    void TheIDTb_DataBinding(object sender, EventArgs e)
    {
        TextBox TheIDTb = (TextBox)sender;
        string str = TheIDTb.NamingContainer.ToString();
        DetailsView container = (DetailsView)TheIDTb.NamingContainer;
        TheIDTb.Text = ((DataRowView)container.DataItem)["id"].ToString();
    }
}
