Hi, Im doing this, but all tools in toolbar are showing? Shouldn't .Clear() do the trick? FYI: Id and body in code below is set from mvc c# variables

@(Html.Kendo().Editor()
.Name(id)
.Events(events => events
.Keyup(change)
)
.Tools(tools => tools.Clear())
.Value(@<text>
@Model.Body
</text>)
)

[Solved] How do I return a value from a Window form field?

I want to show a Kendo window, type something in a textbox in the window, and return the value from to the parent page. How can I do this?

My window definition.

<kendo-window name="InstallerSearch"

title="Search for Installer"

draggable="true"

resizable="true"

width="1100"

height="550"

modal="true"

visible="false"

on-close="onClose"

actions="actions"

iframe="true">

<content>

loading...

</content>

<popup-animation enabled="true" />

</kendo-window>

JavaScript to open window

function selectInstaller() {

var window = $("#InstallerSearch").data("kendoWindow");

window.refresh({

url: "@Url.Content("/Admin/Installers/Search/")"

});

window.open();

window.center();

}

Razor page content for the window

Installer Name<br />

<input name="InstallerName" id="InstallerName" type="text" class="form-control-md" />

JavaScript for the close where I want to get the value in the textbox in the window but user input is undefined.

function onClose() {

var userinput = $("#InstallerName").val();

alert(userinput);

}

SplitButton dropdown arrow position for ToolBar in RTL mode

Hello,

I am using a Kendo Toobar in RTL mode, and I have a couple of SplitButtons on it. I have two questions:

1- Since the Toolbar is set to display its contents in Right-to-Left (RTL) mode, the drop-down arrows for the SplitButtons are displaying on the left side (which is understandable). However, I would like these arrows to display on the right side of the SplitButtons. How can I achieve this?

2- There is a line separating the drop-down arrow and its text (please see image). How do I remove this line so that it's one smooth box?

Thanks,

Shawn A.

[Solved] Set grid values of cell based on selected row criteria

Hi All,

I created a simple project using the Telerik grid template. In my script, I update "Freight" to zero for the selected row. However, I want to set ALL ROWS that match the CustomerID of the selected row to zero.

Here are the peices:

VIEW

@{

ViewData["Title"] = "Home Page";

}

<div class="row">

<div class="col-xs-18 col-md-12">

@(Html.Kendo().Grid<TelerikAspNetCoreApp3.Models.OrderViewModel>()

.Name("grid")

.Selectable()

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

.Events(events =>

{

events.Change("onSelectedRow");

})

.Columns(columns =>

{

columns.Bound(p => p.CustomerID)

.ClientGroupHeaderColumnTemplate("CustomerID");

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

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

})

.Pageable()

.DataSource(dataSource => dataSource

.Ajax()

.PageSize(20)

.Read(read => read.Action("Orders_Read", "Grid"))

.Group(groups =>

{

groups.Add(g => g.CustomerID);

})

.Model(model =>

{

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

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

})

)

</div>

<script>

function onSelectedRow(e) {

var gview = $("#grid").data("kendoGrid");

var selectedItem = gview.dataItem(gview.select());

var custId = selectedItem.CustomerID;

//I want to update ALL freight fields to 0 where CustomerID equals custId, not just the selectedItem

selectedItem.set("Freight", 0); //Fix or update this to update all rows

}

</script>

MODEL

namespace TelerikAspNetCoreApp3.Models

{

public class OrderViewModel

{

public int OrderID {get;set;}

public double CustomerID{get;set;}

public decimal? Freight{get;set;}

}

CONTROLLER

namespace TelerikAspNetCoreApp3.Controllers

{

public class GridController : Controller

{

public ActionResult Orders_Read([DataSourceRequest]DataSourceRequest request)

{

var result = Enumerable.Range(0, 50).Select(i => new OrderViewModel

{

CustomerID = (i+100)/10,

OrderID = i,

Freight = i * 10

});

var dsResult = result.ToDataSourceResult(request);

return Json(dsResult);

}

If this is completely the wrong approach, I'll take ideas for a better/easier solution.

Thank you in advance!

TagHelper - value-axis-item : notes

I want to display a line on the value axis of my bar chart. When using JS it can be done like this:

valueAxis: {

notes: {

line: {

length: 340,

width: 3,

color: "#ff0000"

},

data: [{value: 730, label: {text: "mid"}}]

}

},

But when using a TagHelper I am missing the "data: [...]" part. How can I tell the notes-taghelper where to draw the line?

<value-axis>

<value-axis-item>

<notes>

<chart-value-axis-notes-line length="340" width="3" />

</notes>

</value-axis-item>

</value-axis>

ModelState.IsValid is false when not selecting a value from cascaded dropdowns

I noticed that my ModelState becomes invalid if the user doesn't select any value from a cascaded set of dropdowns. Once you select a value, it becomes valid. How do I fix this, and actually save my model if the user doesn't actually select anything? Not selecting anything just means I won't save anything on Post.

thanks

ImageBrowser shows "undefined" items

Hello,

I have problem with the ImageBrowser component inside the Editor component in .NET Core 2.2. (It's working in the local example, but I not find the difference)

I use the local example as starting point, I copy the code from the example to my project.

1. My controller:

using System;

using System.Collections.Generic;

using System.IO;

using System.Linq;

using System.Net.Http.Headers;

using System.Threading.Tasks;

using Kendo.Mvc.UI;

using Microsoft.AspNetCore.Hosting;

using Microsoft.AspNetCore.Http;

using Microsoft.AspNetCore.Mvc;

using MyCoreSite.Models.Image;

using MyCoreSite.Mvc.Attributes;

namespace MyCoreSite.Areas.Admin.Controllers

{

[ViewLayout("_LayoutAdmin")]

public class ImageBrowserController : EditorImageBrowserController

{

private const string contentFolderRoot = "shared/";

private const string folderName = "Images/";

private static readonly string[] foldersToCopy = new[] { "shared/images/employees" };

/// <summary>

/// Gets the base paths from which content will be served.

/// </summary>

public override string ContentPath

{

get

{

return CreateUserFolder();

}

public ImageBrowserController(IHostingEnvironment hostingEnvironment)

: base(hostingEnvironment)

{

}

public override JsonResult Read(string path)

{

var z = base.Read(path);

return z;

}

private string CreateUserFolder()

{

var virtualPath = Path.Combine(contentFolderRoot, "UserFiles", folderName);

var path = HostingEnvironment.WebRootFileProvider.GetFileInfo(virtualPath).PhysicalPath;

if (!Directory.Exists(path))

{

Directory.CreateDirectory(path);

foreach (var sourceFolder in foldersToCopy)

{

CopyFolder(HostingEnvironment.WebRootFileProvider.GetFileInfo(sourceFolder).PhysicalPath, path);

}

return virtualPath;

}

private void CopyFolder(string source, string destination)

{

if (!Directory.Exists(destination))

{

Directory.CreateDirectory(destination);

}

foreach (var file in Directory.EnumerateFiles(source))

{

var dest = Path.Combine(destination, Path.GetFileName(file));

System.IO.File.Copy(file, dest);

}

foreach (var folder in Directory.EnumerateDirectories(source))

{

var dest = Path.Combine(destination, Path.GetFileName(folder));

CopyFolder(folder, dest);

}

2. My view:

@* Make sure tag helpers are not available for the Editor content *@

@removeTagHelper "*, Microsoft.AspNet.Mvc.Razor"

@removeTagHelper "*, Microsoft.AspNetCore.Mvc.Razor"

@{

ViewBag.Title = "Template";

PageInfo PI = ViewBag.PI;

)

.Value(@<text>

)

</div>

@section Styles {

}

@section Scripts {

}

3. The result:

[Attached file: teler1.jpg]: It's shows undefined items. The image file structure can be find at the right. The item and file count are equal.

[Attached file: teler2.jpg]: It seems that the control detect the files as a directory instead of file.

4. Reference scripts used:

<script src="/js/telerik/jszip.min.js"></script>

<script src="/js/telerik/kendo.all.min.js"></script>

<script src="/js/telerik/kendo.aspnetmvc.min.js"></script>

<script src="/js/telerik/cultures/kendo.culture.en-US.min.js"></script>

<script src="/js/telerik/messages/kendo.messages.en-US.min.js"></script>

<script type="text/javascript">

$(document).ready(function () {

kendo.culture("en-US");

});

</script>

Can you help me please solve this problem?

Thank you!
