I have a kendo grid with grouping and endless scrollbar. I am trying to update dataItem(s) using dataItem.set with an external button click. dataItem.set is not firing change event and data is not being updated. 

Can someone help me with the issue.

i did not bind Multicolumndroupdownlist

view

                        @(Html.Kendo().MultiColumnComboBox()
              .Name("customers")
              .Placeholder("Select customer")
              .DataTextField("CustName")
              .DataValueField("CustomerID")
              .Columns(columns =>
              {
                  columns.Add().Field("CustName").Title("Name");
                  columns.Add().Field("CustomerID").Title("ID");
              })
              .HtmlAttributes(new { style = "width:100%;" })
              .Filter("contains")
              .AutoBind(false)
              .MinLength(2)
              .DataSource(source =>
              {
                  source.Read(read =>
                  {
                      read.Action("GetCustomers", "OrderManagement");
                  })
                  .ServerFiltering(true);
              })
            )

Controller

 public ActionResult GetCustomers(string text)
        {
            ApplicationDbContext db = new ApplicationDbContext();
            var customers = db.Customers.Select(customer => new Customer
            {
                CustomerId = customer.CustomerId,
                CustName = customer.CustName,
                PhoneNo = customer.PhoneNo
            });

            if (!string.IsNullOrEmpty(text))
            {
                customers = db.Customers.Where(p => p.CustName.Contains(text));
            }
           // return Json(GetOrders().ToDataSourceResult(request), JsonRequestBehavior.AllowGet);
            return Json(customers, JsonRequestBehavior.AllowGet);
        }

Hello everyone,

if I use a HierarchicalDataSource with serverFiltering set to true, filter requests are being sent to my remote data source. The problem is though, that already selected items can not be removed any more by clicking on the delete icon after the dataSource has been reloaded, probably due to changed uid's. Is there a workaround for this?

Bye,

Bo

Hi,

We have a scenario that shows a form (e.g. with field A and field B) with multiple text fields being edited using MVVM tied to a data source that’s is set to AutoSync. This datasource is tied to a remote connection, so there can be a momentary lag e.g. 1-2 secs.

What we can observe is that :-
- The user types in field A
- The user then clicks on field B, and starts typing… 
- As the field A lost focus, AutoSync has kicked in (so network request starts)
- User starts to type in field B, but then previous network request finishes and fieldB resets to the value in the datasource, effectively undoing what the user has just typed

Is this ‘expected’ behaviour? Do you know any methods (or workarounds) to prevent this?  Or do we need to disable AutoSync?

Is there any documentation about what events on html input fields that MVVM / AutoSync use, and when ?

Thanks

Chris

I have an application that uses an input for the user to enter a number. When the input is changed another field is recalculated based on the value entered. Because the application is used in different cultures and because the telerik interferes on data binding (see https://www.telerik.com/forums/numeric-input-on-popup-edit-on-different-language) with the decimal separator I have to change the input to a telerik numerictextbox. However the input event does not exist on the numerictextbox.

I tried using numerictextbox_text.on('input keyup', calculate) but they do not work. How can I have the input event on the numerictextbox?

I have a page that contains a grid. The grid contains a number column. The grid is using a custom popup editor. For the number column I am using an input instead of the telerik control for numbers.

The application is localized.

When I am using a culture where the decimal separator is comma(",") when changing the number after leaving the input the decimal separator is changed from comma to point.

I have prepared a demo

https://dojo.telerik.com/UvAfafor/2

Here are the steps to reproduce the problem:

1. Edit the 5th row (the one that has decimals 21.35 - anyone that has decimals should work)

2. Change the decimal point from point to comma (The code from gridEdit does not work - even though in my application works[however I am using globalize package])

3. Leave the input (The decimal point should remain to comma)

4. Go to UnitPrice and add at the end a new digit (can be added or removed any digit as long as the comma is not removed)

5. Leave the input => wrong behavior the comma is converted to point.

=> expected behavior the comma should remain regardless of how many times I change the value
