Navigation with Parameter on Button Click

Using this Grid with the Groups command button definition, I want to navigate to another MVC Action passing a CustomerId value as a parameter. I have an Event handler (with no JavaScript) but am not sure if this is the right approach. Should this be some type of HTML call? If JavaScript is the right way to do this then please supply some code.

This is for ASP.NET Core. Thanks in advance for your help, Joel.

@(Html.Kendo().Grid<GsiPortal.Models.Customer>()

.Name("grid")

.Columns(columns =>

{

columns.Bound(p => p.Name);

columns.Bound(p => p.DisplayName).Title("Display Name");

columns.Bound(p => p.AddTimestamp).Format("{0:MM/dd/yyyy}");

columns.Command(command => command.Custom("Groups").Click("goGroups"));

columns.Command(command => command.Edit()).MinResizableWidth(75);

columns.Command(command => command.Destroy()).MinResizableWidth(75);

})

.Editable(editable => editable.Mode(GridEditMode.InLine)) //.TemplateName("CustomerEdit")) //Turn on the inline cell editing by setting

.Pageable()

.Selectable(selectable => selectable.Mode(GridSelectionMode.Single))

.PersistSelection(true)

.Navigatable()

.Sortable()

.Scrollable()

.Filterable()

.HtmlAttributes(new { style = "height:550px;" })

.DataSource(dataSource => dataSource

.Ajax()

.PageSize(20)

.ServerOperation(false)

.Events(events => events.Error("error_handler"))

.Model(model =>

{

model.Id(p => p.Id);

model.Field(p => p.Id).Editable(false);

model.Field(p => p.AddTimestamp).Editable(false);

})

.Read("IndexJson", "Customers")

.Update("Edit", "Customers")

.Create("CreateJson", "Customers")

.Destroy("DeleteJson", "Customers")

))

Event Handler Example

I need a TreeView example for ASP.NET Core 2.2 that uses Binding and shows me how I can capture the drag/drop events from the control with some context information. Your example shows that it can be done but I see no way to capture the data item that is bound to the node or even wire up a KeyValue to a node so when it is clicked that I have a breadcrumb back to my data store.

I appreciate your help,

Joel

My current TreeView:

Html.Kendo().TreeView()

.TemplateId("treeview-template")

.DragAndDrop(true)

.Name("kendoTreeView")

.Events(events => events

.Change("onChange")

.Select("onSelect")

.Drop("onDrop")

.DragEnd("onDragEnd")

)

.BindTo(Model, (NavigationBindingFactory<TreeViewItem> mappings) =>

{

mappings.For<Group>(binding => binding.ItemDataBound((item, group) =>

{

item.Text = group.Name;

item.Id = $"{group.Id}";

item.ImageUrl = group.ImageUrl;

item.Expanded = true;

})

.Children(group => group.Children));

})

)

<script>

var treeview;

function onSelect(e) {

alert(e.node);

}

function onChange(e) {

alert(e.node);

}

function onDrop(e) {

alert(e.node);

}

function onDragEnd(e) {

alert(e.node);

}

$(document).ready(function() {

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

});

</script>

MultiSelect always returns null as Editor Template

I have a multiselect setup as an Editor Template utilized by the grids popup editor, the control loads properly, displays the data, allows me to select multiple Order Types, but then returns null to my model every time when I save the changes on the popup editor.

How do I wire up the value of the MultiSelect to my model when it is an Editor Template for a Grid Popup?

Here is my Editor Template code:

@model IEnumerable<int>

@(Html.Kendo().MultiSelect()

.Name("OrderTypeIDs")

.DataTextField("Description")

.DataValueField("OrderTypeID")

.DataSource(d => d

.Ajax()

.Read(r => r

.Action("OrderTypes_Read", "Locations")

.Data("GetSelectedClientID")))

.TagMode(MultiSelectTagMode.Multiple)

.Value(Model)

)

Here is the underlying model class:

public class LocationsModel : INotifyPropertyChanged

{

public LocationsModel() : base()

{

}

[ScaffoldColumn(false)]

public decimal LocationId { get; set; }

[ScaffoldColumn(false)]

public string ClientID { get; set; }

[DisplayName("Code")]

[Required]

public string LocationCode { get; set; }

[Required]

public string Name { get; set; }

[DisplayName("Address 1")]

[Required]

public string Address1 { get; set; }

private string address2;

[DisplayName("Address 2")]

public string Address2

{

get => address2 ?? "";

set => address2 = value ?? "";

}

[Required]

public string City { get; set; }

[Required]

public string State { get; set; }

[Required]

public string Country { get; set; }

[DisplayName("Zip Code")]

[Required]

public string ZipCode { get; set; }

[DisplayName("Phone")]

[Required]

public string PhoneNumber { get; set; }

[UIHint("OrderTypeIDs")]

[DisplayName("Allowed Order Types")]

public IEnumerable<int> OrderTypeIDs { get; set; }

[DisplayName("# of O Types")]

[ReadOnly(true)]

public int OrderTypeCount => OrderTypeIDs?.Count() ?? 0;

[ScaffoldColumn(false)]

public string CreatedBy { get; set; }

[ScaffoldColumn(false)]

public DateTime CreatedOn { get; set; }

[ScaffoldColumn(false)]

public string LastUpdatedBy { get; set; }

[ScaffoldColumn(false)]

public DateTime LastUpdatedOn { get; set; }

public event PropertyChangedEventHandler PropertyChanged;

}

Bootstrap 4 update needed for Color Theme Sass Tool ?

I using VS 2017 15.9.3 + asp.net core + mcv ( + razor )

created the project with telerik Project Asp.net core + Grid selection.and created 3 times with the sass theme generator a template and replaced in

_Layout.cshtml the stylesheet

<environment names="Development">
    <link rel="stylesheet" href="~/lib/bootstrap/dist/css/bootstrap.css" />
    <!--link rel="stylesheet" href="~/css/site.css" /-->
    <link rel="stylesheet" href="~/css/all.css" />
</environment>
<environment names="Staging,Production">
    <link rel="stylesheet" href="https://ajax.aspnetcdn.com/ajax/bootstrap/3.3.6/css/bootstrap.min.css"
          asp-fallback-href="~/lib/bootstrap/dist/css/bootstrap.min.css"
          asp-fallback-test-class="sr-only" asp-fallback-test-property="position" asp-fallback-test-value="absolute" />
    <!--link rel="stylesheet" href="~/css/site.min.css" asp-append-version="true" /-->
    <link rel="stylesheet" href="~/css/all.css" asp-append-version="true" />
</environment>

but anyhow the Grid looks ugly in the footer any time.

i found this blog https://www.telerik.com/blogs/getting-started-telerik-ui-for-asp-net-core-and-bootstrap-4

but i do not understand how to do the update

>>No matter how you choose to manage your dependencies, the default layout (i.e _Layout.cshtml) should contain references to them. The default layout >>defines a top level template for views in your web application. These references include the following:

where to store the references , where to reference them etc..

it´s a little bit confusing me so please is there some better help tan this how to update or maybe it´s not needed anyhow to solve the grid ui problem ?

thanks br thomas

Cascading binding and tag helpers

I am having some strange issue with cascading binding.

This code here does work:

<kendo-dropdownlist name="Countries" bind-to="@(new SelectList(Model.Countries,"Id","CountryName"))"></kendo-dropdownlist>

@(Html.Kendo().DropDownList()

.Name("DocumentTypes")

.DataTextField("Name")

.DataValueField("Id")

.BindTo(Model.GovIdTypes)

.CascadeFrom("Countries")

.CascadeFromField("IssuingCountry.Id")

)

But this one does not:

<kendo-dropdownlist name="Countries" bind-to="@(new SelectList(Model.Countries,"Id","CountryName"))"></kendo-dropdownlist>

<kendo-dropdownlist name="DocumentTypes" bind-to="@(new SelectList(Model.GovIdTypes,"Id","Name"))" cascade-from="Countries" cascade-from-field="IssuingCountry.Id"></kendo-dropdownlist>

I don't know why I cannot se the tag helper here.

The first dropdown I got to work with tag helper but the second one not.

Place variable in title

As you have read the title. I want to add a variable in my title. When I put a property in my model, and also define the model in my div. It still gives me the error:

The name 'property' does not exist in the current. But when I add series for example I can do Model => Model.propname Why is it not possible to do this? sTotalCount is in Model2
The code:

@model model1

<div class="demo-section k-content wide">

@(Html.Kendo().Chart<App.Model2>()

.Name("test" + Model1.ID)

.Title(sTotalcount + "this is the total")
