Model Data Not Present when passing from View to Controller

I have a MVC application where I am passing a data model to the view and then when I click the submit button I want to pass the model back to the controller. When I receive the model in the controller it contains no data. I am using the "MaskedTextBoxFor()" for most fields and then a "DatePickerFor()".

01.@model Keying.Models.Invoice

02.

03.@using (Html.BeginForm("Shipment", "Home", FormMethod.Post, new

04. {

05. @class = "form-horizontal",

06. role = "form",

07. id = "submitForm",

08. myInvoice = Model

09. }))

10.{

11. <label>

12. Invoice Number

13. </label>

14. @(Html.TextBoxFor(model => model.InvoiceNumber)

15. )

16.

17. <label>

18. Invoice Date

19. </label>

20.

21. @(Html.Kendo().DatePickerFor(model => model.ShipDate)

22. .Name("ship_date")

23. .Value(DateTime.Today)

24. )

25.

26. <label>

27. Bill to Account

28. </label>

29.

30. @(Html.Kendo().MaskedTextBoxFor(model => model.BillAccount)

31. .Name("bill_account")

32. )

33.}

1.public ActionResult Shipment(Invoice myInvoice, string button)

2.{

3. var shipment = new Shipment();

4. // other processing

5. return View(shipment);

6.}

So with the code snippets above the Invoice Data model going to the view is populated with some data but when it returns to the controller it contains no data.

Thanks,

SignalR and Recurrence exceptions not working correctly

I am trying to hook up SignalR with the MVC scheduler based on the examples given in Github and when I try to make a recurrence exception the Update event is called to update the parent but there is never a trigger for the Create to create the new database entry for the recurrence exception. It is my understanding that when you create a recurrence exception it saves to the database as a new entry linking to the original recurrence via an Id( I don't remember if it is the RecurrenceId or a different one). Is this correct? If so is this a known error because I have used the Scheduler just as it is explained how to set it up in your tutorials and it works fine but now that I am using the SignalR method it is not working.

External Template for column

Hello,

I would like to use an external template for a column in my grid.

@(

Html.Kendo().Grid<ViewModels.UserSummary>()

.Name("EmployeeGrid")

.Columns( columns => {

columns.Bound(c => c.FirstName);

columns.Bound(c => c.LastName);

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

columns.Bound(c => c.LastLogin).Format("{0:dd-MMM-yyyy}");

columns.Bound(c => c.Active).Title("Active").ClientTemplate("myTemplate");

})

.DataSource(ds => ds.Ajax()

.PageSize(24)

.Read(r => r.Action("GetEmployees", "Employee"))

)

.Pageable()

.Sortable()

)



<script id="myTemplate" type="text/x-kendo-template">

    <input type='checkbox' value='testing'

        #= Active ? 'checked' : '' #

        disabled

    ></input>

</script>

Of course this doesn't work, as it just prints 'myTemplate' on each row of that column. I know I can inline the template but I would like to keep things tidy by having the template external. Is this possible with the kendo mvc extensions?

Treeview in left pane and detail in right pane

I'd like to use a splitter control that has two vertical panes. In the left pane I'd like to have a treeview control. When the user selects a node in the treeview, I'd like to populate the right-hand splitter pane with a partial view that displays more detail for the selected treeview node. Please could you provide guidance as to how I can achieve this?

Theme builder questions

My organization is fairly new to Telerik and I have been tasked with two goals to start with. The first is to use the theme builder to try to get the colors to match our existing desktop apps, easy enough for the most part.

Our app is going to be a Core MVC app, so I start by selecting 'UI for ASP.NET Core'. From there I have tried playing with both Default and Bootstrap (though I am honestly not sure which of the two I should be using). After I get everything mostly looking how I want I have no issues downloading the file, but I am unsure exactly where to place it.

In Visual Studio I am creating a new Telerik C# ASP.NET Core MVC Application, from there I am selecting Grid and Menu in the project wizard. From there I am not entirely sure where to place the all.css and variables.scss files to preview the changes to the basic app.

My final question is, within the theme builder the color swatches has a nice side menu that pops out. Which control in Telerik would this be?

Apologizes for all the questions, trying to wrap my head around all of this. Hopefully this all makes sense and I gave enough information.

DateRangePicker without end date

Hi!

I ve been checking out the new DateRangePicker control, and i had some doubts about its usage

1) Is there a chance to make the end date optional? the demo published always focuses on the end date input after selecting a start date, and i want it to be optional, by that i mean to be able to select a start date and end date, o only one of them and the remaining date field to remain empty. Is that possible?

2) I havent seen any binding method like there is for the date picker control. In the latest, there is a DatePickerFor method, to bind the control to the viewmodel field. In the daterangepicker control i expected to be the same method (configuring the start date field and the end date field)... where my assumptions wrong? If thats the case i dont see too much use to this control :/

thanks!

Accessing TreeViewItemModel

Hello, I am currently evaluating the Telerik control sets for use in a large project to start soon. I have a requirement where we will be building a treeview in our ASP.NET MVC controller code using TreeViewItemModel list and passing to the view. In the view razor code and/or javascript, is there a way to access the TreeViewItemModel as a user is selecting different nodes in the tree? Specifically, when building the TreeViewItemModel, I populate the .Text and .Id properties and I need to access these values to post back to my controller code to handle the selection changes. Is this possible? I need to quickly mock something up to demonstrate this.

Controller code to build the treeview contents is here:

public List<TreeViewItemModel> BuildTreeContents()
{
List<TreeViewItemModel> tree = new List<TreeViewItemModel>();
IQueryable<SupplierModel> suppliers = GetSuppliers();
IQueryable<ManagedOrgModel> managedOrgs = null;
IQueryable<ManagedLocationModel> locations = null;
TreeViewItemModel node = null;
List<TreeViewItemModel> orgs = null;
List<TreeViewItemModel> locs = null;
foreach (SupplierModel supplier in suppliers)
{
node = new TreeViewItemModel();
node.Text = supplier.SupplierName;
node.Id = supplier.SupplierID;
managedOrgs = GetManagedOrgs(supplier.ClientID, supplier.SupplierID);
orgs = new List<TreeViewItemModel>();
foreach (ManagedOrgModel managedOrg in managedOrgs)
{
TreeViewItemModel orgNode = new TreeViewItemModel();
orgNode.Text = managedOrg.ManagedOrgName;
orgNode.Id = managedOrg.ManagedOrgID;
locations = GetLocations(managedOrg.ClientID, managedOrg.SupplierID, managedOrg.ManagedOrgID);
locs = new List<TreeViewItemModel>();
foreach (ManagedLocationModel location in locations)
{
TreeViewItemModel locationNode = new TreeViewItemModel();
locationNode.Text = location.ManagedLocationName;
locationNode.Id = location.ManagedLocationID;
locs.Add(locationNode);
}
orgNode.Items = locs;
orgNode.HasChildren = true;
orgs.Add(orgNode);
}
node.Items = orgs;
node.HasChildren = true;
tree.Add(node);
}
return tree;

Thanks,

Doug Matulis
