CheckboxFor in MVC using Razor view

Question

Hi I am creating Dynamic Forms in which i have textboxes and checkboxes as well , i was using html input type for checkbox but it is not getting value and while submitting the form it says that your checkbox column like Active column does not have a valid value i found on internet and find that i need to use @html.checkboxFor rather than html tags so how do i write the below line with html.checkboxfor as i have educatuons[0].isActive as the model item is an array

Check for Model or Model.educations[0] must not be null else it will give you error

You are trying to building a dynamic form, as Priyanka Jain said, the first check should be Model and Education list null check then after you need to loop the Education list to build dyanmic form for all items in Education list. You can try something like below, once you submit the form you will get updated Education list with IsFinalDegree true for selected items else false for others. @using (Html.BeginForm( "Add" , "Student" , FormMethod.Post, htmlAttributes: new { id = "AddStudentForm" })) { if (Model?.Education?.Count != 0) { for ( int i = 0; i { Name.... @Html.CheckBoxFor(m => Model.Education[i].IsFinalDegree, new { id = "switch17" }) } "submit" class = "btn btn-primary" > class = "fa fa-save" >Save } }
