Problem in server side(controller)

public ActionResult Edit(FormCollection form)
{
// check string ids give me null value although text box ids have value in view
string ids = form["ids"];
return View();
}

This variable ids represent as text box in view and i check it in view it have values. this text box have values after i remove courses from table it send removed courses ids to text box ids .

$("#tb").on("click", ".r", function () {
$(this).parent().parent().hide();
$(this).parent().prev().prev().find("input").addClass("remove");
var ids = [];
var i = 0;
$(".remove").each(function () {
ids[i] = $(this).val();
i++;
});
$("#ids").val(ids);
});
@using (Html.BeginForm())
{
"tb">
"submit" value="save" />
"text" name="ids" id="ids" />

Design the HTML code:
@using (Html.BeginForm("Edit", "Home", FormMethod.Post))
{
   <div>
      <table id="tb">table>
      <input type="text" name="ids" id="txtId" />
      <input type="submit" value="save" />
   div>
}
Try with below options:
[HttpPost]
public ActionResult Edit(FormCollection formObj)
{
    if(formObj != null)
    {
        string data = formObj["ids"];
    }
}

or

[HttpPost]
public ActionResult Edit()
{
    string data = Request.Form["ids"];
}

or

[HttpPost]
public ActionResult Edit(string ids)
{
    string data = ids;
}

I checked in my local it is working fine.. In previous answer I mentioned different ways to get data.
Check the value in ids variable, you are just pointng the debug point at the line where it assign the value. Just execute it and see the value...

I make as you tell me
@using(Html.BeginForm("Edit","Employeedata",FormMethod.Post))
{
"tb">
"submit"value="save"/>
"text"name="ids"id="ids"/>
}
