}|code-block|syntax|javascript|4208715|您必须编写更多的代码，但是您可以避免在标记中添加太多的逻辑，也不必使用容易出错和打字的Response.Write。|4208716|你甚至可以用强类型的对象做到这一点！假设你有一个person类：|4208717|public+class+Person

<p>If you want to create server side controls, you're better off using an <code>asp:Repeater</code>:</p>

<pre><code>&lt;asp:Repeater runat="server" ID="Repeater1" OnItemCommand="Repeater1_ItemCommand"&gt;
    &lt;ItemTemplate&gt;
        &lt;li&gt;
            &lt;asp:Button runat="server"  ID="RepeaterButton" Text="&lt;%# Container.DataItem %&gt;" OnClick="RepeaterButton_Click"/&gt;
        &lt;/li&gt;
    &lt;/ItemTemplate&gt;
&lt;/asp:Repeater&gt;

protected void Page_Load(object sender, EventArgs e)
{    
    if(IsPostBack) return;
    var data = new List&lt;string&gt; { "Test1", "Test2", "Test3", "Test4" };
    Repeater1.DataSource = data;

    Repeater1.DataBind();
}
</code></pre>

<p>You have to write a bit more code, but you avoid adding to much logic into your markup and do not have to use Response.Write, which is prone to errors and typos.</p>

<p>You can even do this with strongly typed objects!
Let's assume you have a person class:</p>

<pre><code>public class Person
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
}
</code></pre>

<p>And you have a method in your .cs file that returns a list of Persons:</p>

<pre><code>IEnumerable&lt;Person&gt; Persons()
{
    for (int i = 0; i &lt; 10; i++)
    {
        yield return new Person { FirstName = $"Foo{i}", LastName = $"Bar{i}" };
    }
}
</code></pre>

<p>You can then reference your object properties in your repeater control:</p>

<pre><code>&lt;asp:Repeater runat="server" ID="Repeater1" ItemType="WebFormsSandbox.Person"&gt;
    &lt;ItemTemplate&gt;
        &lt;li&gt;
            &lt;asp:Button runat="server"  ID="RepeaterButton" Text="&lt;%#: Item.FirstName %&gt;  &lt;%#: Item.LastName %&gt;" OnClick="RepeaterButton_Click"/&gt;

        &lt;/li&gt;
    &lt;/ItemTemplate&gt;
&lt;/asp:Repeater&gt;
</code></pre>

<p>I've been stuck for the last two hours and need help.  I've tried every single example I could find online and none of them work.  I'm building a web page in <code>ASP.NET</code> and want to make a list of buttons.  Doesn't seem too hard right?  It's been causing me issues though.</p>

<p>This is my code:</p>

<pre><code>&lt;ul&gt;
  &lt;form id="tagloop" runat="server"&gt;
    &lt;% foreach (string i in data)%&gt;
      &lt;%Response.Write("&lt;li&gt;&lt;button runat=\"server\" type=\"submit\" onserverclick=\"ClickTag\"&gt;" + i + "&lt;/button&gt;&lt;/li&gt;");%&gt;
  &lt;/form&gt;
&lt;/ul&gt;
</code></pre>

<p>If I remove the <code>Response.Write()</code> it only loops once but the one button it does generate actually works and calls the method on click.  Also, the variable i doesn't apply.</p>

<pre><code>&lt;ul&gt;
  &lt;form id="tagloop" runat="server"&gt;
    &lt;% foreach (string i in data)%&gt;
      &lt;li&gt;&lt;button runat="server" type="submit" onserverclick="ClickTag"&gt; i &lt;/button&gt;&lt;/li&gt;
  &lt;/form&gt;
&lt;/ul&gt;
</code></pre>

<p>Is there anyway I can get it to loop, have the text of i in data, and also call the correct function on click?  I haven't been able to find a balance of all three yet and any help will be appreciated.</p>
