问题
I am doing a classic search field with a button. I am using Ajax.ActionLink for the button, and I cannot figure out how to get the textbox value posted in the ActionLink. I looks like this:
<div class="input-append">
<input type="text" id="Company_CompanyName" />
@Ajax.ActionLink("search",
"CompanySearch",
new { searchString = "???" },
new AjaxOptions
{
HttpMethod = "GET",
InsertionMode = InsertionMode.Replace,
UpdateTargetId = "CompanySearchResults"
},
htmlAttributes: new { @class = "btn" })
</div>
<div id="CompanySearchResults"></div>
Where the ??? is, is where I don't know how to get the value from the textbox in. What do I do?
UPDATE 1: It is a nested form
As I should have mentioned in the original post/question, this is a nested form, i.e. there is an outer form to be submitted. Therefore if I make a Ajax.BeginForm() with a submit inside it, it will invoke the submission of the outer form. I obviously want to avoid that.

Okay, so, I'd try making it a 'dumb' link/button and handling all the information passing by way of javascript. It would look something like the following.
I believe there are syntax errors in the following script so only use it as a guideline.
<input type="text" id="Company_CompanyName" />
<a href="#" id ="CompanySearch" class="btn">Search</a>
<div id="CompanySearchResults"></div>
<script type="text/javascript">
$('#CompanySearch').click(function() {
var searchTerm = $("#Company_CompanyName").text();
$.ajax({
url: @Url.Action("search","CompanySearch") ,
type: 'POST',
contentType: 'application/json; charset=utf-8',
data: {'SearchTerm' : searchTerm} // JSON.stringify(searchTerm),
success: function(result) {
$('#CompanySearchResults').html(result);
}
});
return false;
});
</script>

This answer is moot b/c the link is wihin a form, I'll try to make another answer in a bit...
Use an ajax form for this - not a link. You need a form to include values in the postback, ie.
@using (Ajax.BeginForm("search", "CompanySearch",new AjaxOptions { HttpMethod = "GET", InsertionMode = InsertionMode.Replace, UpdateTargetId = "SearchResults" }))
{
<h1>Search</h1>
<input type="text" placeholder="Search Terms" name="SearchTerms"/>
<input type="submit" name="Command" value="Search" />
}
<div id="SearchResults"></div>
