How does one do a 'Cancel' on a Form widget. I see the events for Submit / Clear / Validate. It looks like the only way to leave a form is to submit it.

Bug with Down Icon Css

I just updated our web application to the new 2020.2.513 core release. However, the css for menu items with children has changed. This causes the down icon to not show correctly. It shows as a box now which is what happens when it can't show the icon. (See attached.)

Old css that worked:

New css that does not work:

If I use the devtools of Chrome and edit the generated css to match the old css, it works again.

So, to me, it's a bug.

However, what I need asap is a way to overcome the bug for now so that the old css is used again.

Localize breadcrumb items

Hi,

Does anyone have a working project that demonstrates how to localize the breadcrumb component?

I have the breadcrumb working by parsing a hidden field for a property in the model populated in the controller.

@(Html.Kendo().Breadcrumb()

.Name("breadcrumb")

.Navigational(true)

.RootIcon("home")

.Value(Model.Breadcrumb)

)

It all works perfectly. Except now, I need to localize the string values displayed in the breadcrumbs. And of course, not disturb the the generated URL mapping to still make the links navigational to the desired controller/action.

Is this even possible using the breadcrumb component?

Thanks

Jason

[Solved] update progress by controller

Hi to all,

I would add a function for witch he will can sync data from his ERP, this process may be very long, but I would show him progress of this process.

I think to use notification but, I don't know if it's a good approach. I think to signalR also, but it seems too much to have only a progressive update.

If it's good way first thing, how can I update from action to current view (signalR????)

What do you suggest me to do?

TreeList Drag/Drop MVC

I need to be able to handle the Drag/Drop activity. I see no examples on how to capture the Drop or DropEnd events when doing this from an ASP.NET Core MVC application. How do I hand off all the appropriate values to the controller? Is this one call to both remove the node from the existing parent and register the node with the new parent?

TreeList

@(Html.Kendo().TreeList<NameValueParent>()

.Name("treelist")

.Columns(columns =>

{

columns.Add().Command(c => { c.Custom().Text("Select")

.Name("selectButton").ClassName("selectButton")

.Click("goDetail"); })

.Width(Glossary.Portal.ButtonWidth);

columns.Add().Field(e => e.Name);

columns.Add().Width(330).Command(c =>

{

c.CreateChild().Text("Add");

c.Edit();

c.Destroy();

})

.HtmlAttributes(new

{

style = "text-align: center;"

});

})

.Events(ev => ev.DataBound("onDataBound"))

.Editable(e => e.Move(true))

.Selectable(s => s.Mode(TreeListSelectionMode.Single))

.DataSource(dataSource => dataSource

.Create(create => create.Action("Create", "Site"))

.Read(read => read.Action("IndexJson", "Site").Data("getData"))

.Update(update => update.Action("Update", "Site"))

.Destroy(delete => delete.Action("Destroy", "Site"))

.ServerOperation(false)

.AutoSync(true)

.Model(m =>

{

m.Id(f => f.Id);

m.ParentId(f => f.ParentId);

m.Expanded(true);

m.Field(f => f.Name);

}).Events(events =>

{

events.Error("onError");

})

)

.Events(events => events.DragEnd("goDropEnd()"))

.Height(540))

Script

function goDropEnd(e) {

alert("goDropEnd");

alert("I have no idea what to do here");

}

Change saveAsExcel() request before sending

Because the grid date filter is still broken (https://github.com/telerik/kendo-ui-core/issues/1864) I have to modify the filter date/time values before the request is made to the server.

I can do this for normal grid filtering by modifying the filter values in the transport parameterMap, however, when I invoke saveAsExcel() the parameterMap is not called and the wrong date/time values are sent to the server.

How can I modify the filter values *before* saveAsExcel() makes the request to the server (just as I do for normal filtering)?

[Solved] Using ClientTemplate with enum and badge

Hi to all,

I'm trying to use a badge to show a value of enum with a color for each items.

this is a enum

public enum ContactSourceTypes

{

[Display(Name = "Telefono")]

Phone = 0,

[Display(Name = "Mail")]

Mail = 1,

[Display(Name = "Sistema di Marketing")]

Mautic = 2,

[Display(Name = "Altro")]

Other = 3

}

Actually it shows a Display Value of item into a grid

[...]

columns.Bound(product => product.SouceType)

[...]

Now, I would obtain a badge with a specific color and displayvalue of item's enum type. To do this I try to change column setup in this way.

columns.Bound(product => product.SouceType).ClientTemplate("<span id='badge_#=SouceType#' class='sourceTypeBadgeTemplate'>#=SouceType#</span>");

And relative script

function onDataBound(e) {

var grid = this;

grid.table.find("tr").each(function () {

var dataItem = grid.dataItem(this);

//Formattazione tipo origine

var sourceType = dataItem.SouceType;

var type = 'primary';

//alert(sourceType);

switch (sourceType) {

case 0:

type = 'primaty';

break;

case 1:

type = 'info';

break;

case 2:

type = 'success';

break;

case 3:

type = 'warning';

break;

}

var text = sourceType;

$(this).find('script').each(function () {

eval($(this).html());

});

$(this).find(".badgeTemplate").kendoBadge({

type: type,

value: text,

});

kendo.bind($(this), dataItem);

});

}

But it's wrong.....where I wrong?

Context Menu on Node

I use TreeList a lot in my Portal. However, instead of having big buttons showing in the grid the users would like to have a context menu. In the simplest form, I'd need to right click and get an option to go to the details or add a sub-node of the selected node.

The node Template:

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

<div class='group-icon'

style='background-image: url(@Url.Content("#: ImageUrl #"));'></div>

<div class='group-name'>#: Name #</div>

</script>

My current TreeList:

@(Html.Kendo().TreeList<Group>()

.Name("treelist")

.Columns(columns =>

{

columns.Add().Field(e => e.Name).TemplateId("icon-template").Width(350);

})

.DataSource(dataSource => dataSource

.Read(read => read.Action("IndexJson", "Groups").Data("getData"))

.ServerOperation(false)

.Model(m =>

{

m.Id(f => f.Id);

m.ParentId(f => f.ParentId);

m.Expanded(true);

m.Field(f => f.Name);

})

.Sort(s => s.Add(f => f.Name))

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

)

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

.Selectable(s => s.Mode(TreeListSelectionMode.Single))

.Events(events =>

{

events.DataBound("onDataBound");

}))

[Solved] Set Selected Item on Load

I have a grid that lists people. When it loads, I need to select a row matching the key I submit and then ensure the row is visible in the window. How do I do this? My attempt (based on what I know of the TreeList):

@(Html.Kendo().Grid<Person>()

.Name("grid")

.Columns(columns =>

{

columns.Command(command => command

.Custom("Select")

.Click("goDetail"))

.Width(Glossary.Portal.ButtonWidth);

columns.Bound(p => p.FirstName)

.Filterable(ftb => ftb.Cell(cell => cell.Operator("contains")

.ShowOperators(false)

.SuggestionOperator(FilterType.Contains)));
