    How to show checkbox selected using MVCCheckBoxList in Asp.Net MVC

    In my previous blog I have discussed about how to use MVCCheckBoxList. Please visit the following link for reference:

    MVCCheckBoxList in Asp.Net MVC

    Issue:
    The problem which I also faced while using MVCCheckBoxList is to show the checkbox selected, when directed to another page after selecting the CheckBoxes. We are always getting the blank CheckBoxes.

    Soln:
    The solution which I got for the above problem is as follows:

    Let us take a Model class for the MVCCheckBoxList :

    public class RegisterationModel
        {
            public IEnumerable<SelectListItem> chkbx { get; set; }
            public string[] chkbxIds { get; set; }
        } 
    

    As discussed in the above mentioned blog to bind the CheckBoxList we use to write the following code :

     IEnumerable<Models.RegisterationModel.CheckBoxOptions> checkBoxOptions = Enum.GetValues(typeof (Models.RegisterationModel.CheckBoxOptions)) .Cast<Models.RegisterationModel.CheckBoxOptions>();
    
      model.chkbx = from action in checkBoxOptions
                                  select new SelectListItem 
                                  {
                                      Text = action.ToString(),
                                      Value = ((int)action).ToString()
                                  };
    

    As discussed in my previous blog public string[] chkbxIds { get; set; } holds the index of the selected CheckBoxes, therefore inorder to show the CheckBoxes selected replace the above code for binding the CheckBoxList :

    IEnumerable<RegisterationModel.CheckBoxOptions> checkBoxOptions = Enum.GetValues(typeof (RegisterationModel.CheckBoxOptions)) .Cast<RegisterationModel.CheckBoxOptions>();
    
                    List<SelectListItem> list = new List<SelectListItem>();
                    foreach (var action in checkBoxOptions)
                    {
                        var select = new SelectListItem();
                        select.Text = action.ToString();
                        select.Value = ((int)action).ToString();
                        if (model.chkbxIds.Contains(select.Value))
                             select.Selected = true;
                             list.Add(select);
                    }
    
                    model.chkbx = list;
    

    Note=>This will check if model.chkbxIds holds the value (i.e the value of the selected checkbox), It will show that Checkbox Checked.

    Hope it helps...!
