Mind you, I am using master pages, but can I locate a div within the page and throw some html in there? Thanks.

You can add a div with runat="server" to the page:
您可以在页面中添加一个带有 runat="server" 的 div：
<div runat="server" id="myDiv">
</div>
and then set its InnerHtml property from the code-behind:
然后从代码隐藏设置它的 InnerHtml 属性：
myDiv.InnerHtml = "your html here";
If you want to modify the DIV's contents on the client side, then you can use javascript code similar to this:
如果你想在客户端修改DIV的内容，那么你可以使用类似这样的javascript代码：
<script type="text/javascript">
Sys.Application.add_load(MyLoad);
function MyLoad(sender) {
$get('<%= div.ClientID %>').innerHTML += " - text added on client";
}
</script>

Use asp:Panelfor that. It translates into a div.
asp:Panel为此使用。它转化为一个 div。

You could reference controls inside the master page this way:
您可以通过以下方式引用母版页内的控件：
void Page_Load()
{
ContentPlaceHolder cph;
Literal lit;
cph = (ContentPlaceHolder)Master.FindControl("ContentPlaceHolder1");
if (cph != null) {
lit = (Literal) cph.FindControl("Literal1");
if (lit != null) {
lit.Text = "Some <b>HTML</b>";
}
}
}
In this example you have to put a Literal control in your ContentPlaceholder.
在此示例中，您必须在 ContentPlaceholder 中放置一个 Literal 控件。

You want to put code in the master page code behind that inserts HTML into the contents of a page that is using that master page?
您想将代码放在母版页代码后面，以便将 HTML 插入到使用该母版页的页面的内容中吗？
I would not search for the control via FindControl as this is a fragile solution that could easily be broken if the name of the control changed.
我不会通过 FindControl 搜索控件，因为这是一个脆弱的解决方案，如果控件的名称更改，很容易被破坏。
Your best bet is to declare an event in the master page that any child page could handle. The event could pass the HTML as an EventArg.
最好的办法是在母版页中声明一个任何子页都可以处理的事件。该事件可以将 HTML 作为 EventArg 传递。

Remember using
记得使用
myDiv.InnerHtml = "something";
will replace all HTML elements in myDIV. you need to append text to avoid that.In that this may help
将替换 myDIV 中的所有 HTML 元素。您需要附加文本以避免这种情况。因为这可能会有所帮助
myDiv.InnerHtml = "something" + myDiv.InnerText;
any html control in myDiv but not ASP html controls(as they are not rendered yet).
myDiv 中的任何 html 控件，但不是 ASP html 控件（因为它们尚未呈现）。
