[Maryem]

J'ai utilisé un treeview telerik et je veux afficher toute la liste des éléments coché  dans un autre formulaire .comment faire ?

Voici le code :
Html.Telerik().TreeView()
            .Name("TreeView")
            .HtmlAttributes(new { style = "width: 300px; float:; margin-bottom: 40px; margin-left: 3px;" })
            .ShowCheckBox(true)

           .BindTo(Model, mappings =>
           {
               mappings.For<HowToTelerikDemo.Models.CategoryTest>(binding => binding
                       .ItemDataBound((item, category) =>
                       {
                           item.Text = category.NomCategory;
                          

                           item.Expanded = true;

                       })

                       .Children(category => category.TestTobDisplayedInTree));


               mappings.For<HowToTelerikDemo.Models.ModelTestForTree>(binding => binding
                       .ItemDataBound((item, test) =>
                       {
                           item.Text = test.TestDisplayedName;
                         


                       }));

 

           })
        .ClientEvents(events => events
                    .OnChecked("TreeView_onChecked")
        )
         .Render();
    
    
}


<script type="text/javascript">

       function treeView() {
           return $('#TreeView').data('tTreeView');
       }

       function TreeView_onChecked(e) {
           var item = $(e.item);
           var isChecked = e.checked;
           var childCheckBoxes = item.find(":checkbox");

           $.each(childCheckBoxes, function (index, checkbox) {
               $(checkbox).attr('checked', isChecked);
               var val = treeView().getItemValue($(checkbox).closest(".t-item"));
               alert("Le test séléctionné est"+ val);
               treeView().nodeCheck(null, checkbox);
           });
       }
</script>
