How can I display an html textbox with value开发者_Go百科 obtained from code behinh?

As long as your string value is not private, you should be able to do something like this

<input type="text" value="<%= YourStringValue %>" />

You could use an actual <asp:Textbox /> and set it's "text" value directly from the code behind. If you want to directly inject text into a "normal" html textbox (or anywhere else for that matter), you can use <%= SomeValue %>. Yet another way is to include the "runat=server" attribute on standard html elements, allowing you to manipulate them from the codebehind.

Normally I'd just go for the built-in ASP textbox control so I don't have to worry about persisting values/wiring up viewstate/etc. Injecting dynamic content into plain html elements tends to be an edge case requirement...
