本文介绍了每次点击都会创建gridview的模板字段列的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
这是我在ajax面板中放置网格视图的aspx代码。
this is aspx code in which I put a grid view in ajax panel.
<body>
<form id="form1" runat="server">
<div>
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:GridView ID="GridView1" runat="server" DataKeyNames="head_code" >
</asp:GridView>
</ContentTemplate>
</asp:UpdatePanel>
</div>
</form>
</body>
以下代码背后：
Following is code behind:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace gridview_button
{
public partial class WebForm2 : System.Web.UI.Page, ITemplate
{
protected void Page_Load(object sender, EventArgs e)
{
hitechLatestEntities database = new hitechLatestEntities();
GridView1.DataSource = database.HEADs;
TemplateField tfObject = new TemplateField();
tfObject.HeaderText = "Sub-Head";
tfObject.ItemTemplate = new WebForm2(ListItemType.Item);
GridView1.Columns.Add(tfObject);
GridView1.DataBind();
}
/////////////////////////////// For template field //////////////////////////////////
public WebForm2()
{
}
public WebForm2(ListItemType Item)
{
myListItemType = Item;
}
private ListItemType myListItemType;
public void InstantiateIn(Control container)
{
if (myListItemType == ListItemType.Item)
{
Button btn = new Button();
container.Controls.Add(btn);
}
}
////////////////////////////////////////////////////////////////////////////////////
}
}
我已经动态创建了模板字段，并且上面的代码工作正常，但唯一的问题是每次当我点击模板字段中的按钮时，会出现一个新的空白模板字段列标题文本。即使是ajax也不适合我。
或
有人能告诉我如何动态地将btn添加到UpdatePanel1吗？
I have created template field dynamically and Above code is working fine but only problem is that every time when i click on button in template field, a new blank template field column appears with same header text. Even ajax is not working for me.
or
can anyone tell me how to add btn to UpdatePanel1 dynamically??
推荐答案
<asp:updatepanel id="UpdatePanel1" updatemode="Conditional" runat="server" xmlns:asp="#unknown">
</asp:updatepanel>
