c# - 如何以编程方式添加 TemplateField

Question

请考虑这段代码:

<asp:TemplateField>
     <ItemTemplate>
         <asp:LinkButton runat="server" ID="linkmodel" Text='<%#Eval("MenuItem") %>' 
                         CommandName='<%#Eval("CommandName") %>'
                         OnCommand="linkmodel_Click" 
                         OnClientClick="return confirm('Are You Sure')">
         </asp:LinkButton>
     </ItemTemplate>
</asp:TemplateField>

如何使用 C# 以编程方式添加此列？

Answer 1

这可能有助于开始:

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    { 
        var linkField = new TemplateField();
        linkField.ItemTemplate = new LinkColumn();
        GridView1.Columns.Add(linkField);
    }
}


class LinkColumn : ITemplate
{
    public void InstantiateIn(System.Web.UI.Control container)
    {
        LinkButton link = new LinkButton();
        link.ID = "linkmodel";
        container.Controls.Add(link);
    }
}

但是:

Although you can dynamically add fields to a data-bound control, it is strongly recommended that fields be statically declared and then shown or hidden, as appropriate. Statically declaring all your fields reduces the size of the view state for the parent data-bound control.
