I want to add the selected item into database

From stackoverflow

• Encode the id of the product that is selected into the name of the check box.

  <%= Html.CheckBox("Selected_" + f.ProductId) %>
  

  The on the server side, iterate through the ValueProviderKeys and find selections and extract the product id from the ones that are selected.

  foreach (var key in this.ValueProvider.Keys.Where( k => k.StartsWith( "Selected_" ) )
  {
       // for a checkbox I think this is something like true,false if the
       // visible checkbox is checked.  There is an invisible checkbox
       // (set to false), that is checked by default so you get both when
       // the true checkbox is checked.
       bool selected = this.ValueProvider[key].AttemptedValue.Contains("true");
       int productID = int.Parse( key.Replace("Selected_",null) );
  
       ...store selected product id in db...
  }
  

• Neatest way is to use model binding for your list of checkboxes, see post here:
