Get Checkbox value from view to controller

Question

I Pass ID as name for checkbox in Grid.MVC ? How to get value of selected Id in controller

But i got null value from controller 

 

@Html.Grid(Model).Named("Grid").Columns(columns =>

{

columns.Add()

.Titled("<input name='allChk' type='checkbox' id='checkbox1' />")

.Encoded(false)

.Sanitized(false)

.SetWidth(30)

.RenderValueAs(c => Html.CheckBox("checked",false, new { @class = "checkBox",name= "inCosId", @[email protected],ID=c.inCosId })).SetWidth(100);

columns.Add(c => c.vcCosCode).Titled("Cost Center Code").Filterable(true);

}).WithMultipleFilters()

 

 

controller:-

var ch = form.GetValue("inCosId");

if (ch != null)

{

}

return View();
