C#.net equivalent of getelementid

[Shane807]

in Javascript i can update <div> innerHTML with simple code

<script type="text/javascript" language="javascript>

function UpdateDivTag(){

document.getElementId("divtagid").innerHTML = "oh no Hello world"

}


<button name="somebuttonname" onClick="UpdateDivTag()">Some button"</button>

does anyone know how to do this from a C# code behind page.

I am using Visual Studio 2005 and one of my includes is

using System.Windows.Form;

Also using quite a few others. Can't seem to find a document model or HTMLDocument to find a function to this.

Mostly irritated.

In the code behind you should know all your elements already.
If not, there is a control finder, it's pretty hard to find, being called "FindControl" and all.

this.FindControl("mycontrolname");

I can use the FindControl to find the element that isn't a proble. The problem is filling in the innerhtml to alter a DIV component. I am looking to use HtmlTextWriterTag. Not sure.

If you want stuff inside a DIV tag, create the element type you want and then .Add() it to the div's object.

Figured it out. Not apparent. You need

using System.Web.UI.HtmlControls;
your tag in the webpage
<DIV ID="BigDiv"></DIV>


then you can reference your DIV tag.


In the C# code behind;


BigDiv.InnerHtml = Server.HtmlEncode("THIS IS IT ");

BigDiv.InnerHtml = "This works too";


The tag name will not show up in the Visual Studio GUI, but you can reference it just like this. Either everyone knew that and I'm slow or you learned something new. Thanks for your help.

if you used ASP:Panel (which translates into a DIV) and used runat="server" it would show up in the intellisense (ctrl+spacebar)
