I want to add the selected item into database

Answer 1

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... }
