Dynamic Content?

my attempt (Where I have Kendo DropDownList 1 as #Type and Kendo DropDownList 2 as #Units:

$('#Type').change(function (e) {
//if (e.target.value == "Electirc") {
var val = e.target.value;
var ddL = $('#Units').data("kendoDropDownList")

if (val == "Electric") {
ddl.dataSource.data({Text:"-", value:"null"},{Text:"kW", value:"kW"},{Text:"GJ", value:"GJ"})
//$("#Units").html("<option value='null'>item1:-</option><option value='kW'>item1: kW</option><option value='GJ'>item1: GJ</option>");
}
})

The goal would be to have the contents of DDL2 to change based on the selection by DDL1

DropDownList

Calling existing views for grid updates

I am using UI for MVC 2015.1.318

I am replacing user admin lists with Telerik grids, but need to call the original views for CRUD. I have reviewed the documentation at http://docs.telerik.com/kendo-ui/aspnet-mvc/helpers/grid/server-editing as well as several forum posts, but the Edit command button always calls the inline editor.

My grid

@(Html.Kendo().Grid(Model.UsersList)

.Name("grid")

.Columns(columns =>

{

columns.Bound(u => u.DisplayName);

columns.Bound(u => u.AccountName);

columns.Bound(u => u.Email);

columns.Command(command => { command.Edit(); command.Destroy(); }).Width(200);

})

.Editable(editable => editable.Mode(GridEditMode.InLine))

.Pageable()

.Sortable()

.Scrollable()

.DataSource(dataSource => dataSource

.Ajax()

.ServerOperation(false)

.PageSize(20)

.Sort(sort => sort.Add("AccountName").Ascending())

.Model(model => model.Id(u => u.UserId))

.Update(update => update.Action("Edit", "UserAdmin"))

.Destroy(destroy => destroy.Action("Delete", "UserAdmin"))

)

There is a UserAdminController.cs with Edit and Delete methods. Here is the Edit:

public async Task<ActionResult> Edit(string id)

{

if (id == null)

{

return new HttpStatusCodeResult(HttpStatusCode.BadRequest);

}

var editUser = await UserManager.FindByIdAsync(id);

if (editUser == null)

{

return HttpNotFound();

}

UserDetailsViewModel vm = new UserDetailsViewModel()

{

Id = editUser.Id,

Email = editUser.Email,

DisplayName = editUser.DisplayName,

SelectedAccountId = editUser.AccountId,

};

// System Admins can assign Account to users, so get a list

if (User.IsInRole("System Admin"))

{

vm.AvailableAccounts = DataRepo.GetAccountListForDdl().ToList();

}

await Edit_SetupRoles(editUser.Id, vm);

vm.ProviderId = editUser.ProviderId;

if (editUser.ProviderId != null)

vm.ProviderName = DataRepo.GetProviderName(editUser.ProviderId);

vm.AccessLevelsAssigned = DataRepo.GetAssignedUserAccessLevels(editUser.Id);

vm.AccessLevelsPool = DataRepo.GetAvailableUserAccessLevels(editUser.Id, editUser.AccountId);

vm.AccountAndClients = DataRepo.GetAccountAndClientListForDdl(editUser.AccountId).ToList();

return View(vm);

}

Where is this going off the rails?

Best,
Scott

Persist Drag and Drop Changes

I apologize up front if there is an obvious answer to this question, but how do I persist the changes that a user makes to the nodes in a tree control when .DragAndDrop(true) is specified? Since the MVC wrappers using a ReadOnly datasource, I'm really not sure how to do that other than starting to look into doing it outside the MVC wrappers.

Thanks,
Kyle

Refresh Treeview after adding item

I'm adding an item and then wanting to refresh the TreeView. It works every other time. The node is always added, but the treeview is refreshed to display it only after I click to add another node. At that time, both new nodes show up. I'm guessing that the first ajax call hasn't completed when the treeview.dataSource.read() statement is reached. Is there a way to execute a "wait" until the AddNode statement has completed?

Here's my javascript:

// Add Node

$("#createCategory").click(function () {

var name = $("#newCategory").val();

if (name != "") {

$.ajax({

url: '@Url.Action("AddNode","Categories")',

type: "POST",

data: {

CategoryName: name

}

});

kendoConsole.log("Adding " + name);

//var treeview = $("#treeview").data("kendoTreeView");

treeview.dataSource.read();

}

else {

kendoConsole.log("Please enter non-empty name");

}

$("#newCategory").val("")

$("#newCategory").focus()

});

Javascript call with parameter from inside a template

I have the following code that I am trying to use to delete an item in the database when someone clicks the delete button:

<script id="treeview-template" type="text/kendo-ui-template">

#: item.name #

<a href="javascript:void(0)" class='btn-sm btn-danger' onclick="DeleteNode(@item.id)">x</a>

</script>

@Html.Kendo().TreeView().Name("Categories").ExpandAll(true).Template("treeview-template").DataSource(dataSource => dataSource

.Model(model => model

.Id("id")

.HasChildren("hasChildren")

)

.Read(read => read.Action("GetCategories", "Categories"))).DataTextField("name").DragAndDrop(true).Checkboxes(true).Events(events => events.Change("onChange").Select("onSelect").Check("onCheck").Collapse("onCollapse").Expand("onExpand").DragStart("onDragStart").Drag("onDrag").Drop("onDrop").DragEnd("onDragEnd"))

The issue I'm having is that the field I'm trying to pass to the function, @item.id, is causing the exception: "The name 'item' does not exist in the current context." How can I format the code so this works?

Thanks.

Laurie
