推荐答案

使用动态按钮的最佳方法是DataList使用包含Button元素的项目模板制作一个DataList.将数据列表与按钮数据收集的dataSource绑定.作为

The Best way to use Dynamic Buttons is DataList Make a DataList with item template containing a Button element. Bind the datalist with dataSource of buttons data collection. As

<asp:datalist id="dlButtons" runat="Server" onitemcommand="dlButtons_Command" xmlns:asp="#unknown">
      <itemtemplate>
              <asp:button id="cmdSubmit" text=''<%#   Eval( "Text" ) %>'' runat="server" commandname=''<%# Eval("Command") %>'' />
      </itemtemplate>

现在在页面加载事件的服务器端处理只需将数据源与数据列表绑定为As

Now Handling on server Side on Page Load Event just bind the data source with Data List like As

 List<Button> buttons = new List<Button>();
 Button b1=new Button();
 b1.Text="Previous";
 b1.Command="Prev";
 buttons.Add(b1);

 Button b2=new Button();
 b2.Text="Next";
 b2.Command="Next";
 buttons.Add(b2);

dlButtons.DataSource=buttons;
dlButtons.DataBind();

现在您可以在此处编写按钮操作代码

Now You can Write Button Action Code here

 private void dlButtons_Command(object sender , DataListCommandEventArgs e)
{
       if(e.Command == "Prev")
       {
             //Write your code here
       }
      if(e.Command == "Next")
      {
             //Write Your Code here
      }
}

询问是否有任何问题....

Ask if any issue comes ....

使用使用System.Web.UI.WebControls;"


按钮button1 = new Button();
button1.ID = btndynamic//创建一个按钮ID

Use "using System.Web.UI.WebControls;"


Button button1 = new Button();
button1.ID = btndynamic //create a buttonid
