Provide name to your checkbox:
@foreach (var item in ViewBag.OtherSearch)
{
var idd = "other" + @item.ID;
<div class="col-lg-6">
<input type="checkbox" class="chk_other" id=@idd value=@item.ID title=@item.SearchCriteria name="chkbox" />
<label for="checkbox" style="font-weight:normal; font-family:Calibri; font-size:12px;">@item.SearchCriteria</label>
</div>
And your action method signature would be:
public ActionResult Index(FormCollection collection)
{
if(!string.IsNullOrEmpty(collection["chkbox"])
{
string checkResp=collection["chkbox"];
bool isChecked = Convert.ToBoolean(checkResp);
}
}
