I have added the cancel event to my grid as follows:

.Events(e => e.Cancel("onCancel")

.......

function onCancel(e) {

......

}

However the function is not being called when I click "Cancel Changes".  According to the documentation, the Cancel event is only fired in the other two edit modes.  How is it possible to trap the clicking of this button in the toolbar?

Many thanks,

Colin

Hi there i have a simple page that has three drop-down fields and grid. The grid has a drop-down column(Product) which is made possible by using an editortemplate, the grid is also in a separate file and is loaded in a partial view. The problem i am running into is when i load the grid using the MVC razor syntax, the drop-downlist in the grid works when i try to add a new entry.

However, when i load the grid using JQuery ajax and try to add a new entry, the grid throws an error saying that the editortemplate is not defined.

Here is the rest of my code.

Index.cshtml

//Grid

How do i solve this problem ?. thanks

I'm having quite a bit of difficulty displaying selected/default values in a DropDownList. I created an appropriate ViewModel:

namespace KendoVolunteerApp.Models.ViewModels
{
    public class OrganizationViewModel
    {
        public int OrganizationId { get; set; }
        public string Name { get; set; }
    }
}

and Controller

using KendoVolunteerApp.Models;
using KendoVolunteerApp.Models.ViewModels;
using System.Linq;
using System.Web.Mvc;
namespace KendoVolunteerApp.Controllers
{
    public class DropDownListController : Controller
    {
        private VolunteersDbContext db = new VolunteersDbContext();
        // GET: DropDownList
       
        public ActionResult DropDownList()
        {
            return View();
        }
        public JsonResult DropDownList_GetOrganizations()
        {
            var organizations = db.Organizations.Select(organization => new OrganizationViewModel
            {
                OrganizationId = organization.OrganizationId,
                Name = organization.Name
            });
            //if  (!string.IsNullOrEmpty(text))
            //{
            //    organizations = organizations.Where(p => p.Name.Contains(text));
            //}
            return Json(organizations, JsonRequestBehavior.AllowGet);
        }
    }
}

The DropDownList is part of a custom editor template.

. . .

 <div>
            <div class="form-group col-md-4">
                <div class="k-label-top">
                    @Html.LabelFor(model => model.Organization)
                </div>
                <div class="k-dropdown">
                    @(Html.Kendo().DropDownListFor(model => model.Organization)
                           .Name("organizations")
                           .Filter("contains")
                           .DataTextField("Name")
                           .DataValueField("OrganizationId")
                           .OptionLabel("Select organization....")
                           .DataSource(source =>
                           {
                               source.Read(read =>
                               {
                                   read.Action("DropDownList_GetOrganizations", "DropDownList");
                               }).ServerFiltering(true);
                              
                           })
                           .HtmlAttributes(new { style = "width: 300px" })                    )
                </div>
            </div>

The DropDownList is being populated, as it should. My issue is that I need to have a particular organization selected by default, in those scenarios where a volunteer is part of an organization. Organization is not  required field, as not all volunteers belong to an organization. There is no relationship between the two tables. The name of the organization is stored in the organization field of the volunteer table.

It's setting this selected/default value that is giving me problems.

I've been through various examples, but could not find anything that met my needs. Any help or suggestions would be very much appreciated.

Thank You

We have a grid which is configured for batch in-cell editing. There is a conditional rule where if the user selects certain types of 'Code' in one column, then another column becomes required. We have implemented this with the following code in the onEdit event of the grid:

if (e.model.code == "A" || e.model.code == "B" || e.model.code == "C" || e.model.code == "D") {
            $("#column_LongNameId").attr("required", true);

}

The issue is the name of the column, "column_LongNameId" is long and user-unfriendly and as such, the 'required' pop-up which appears when the user clicks Save Changes, has the message appears "column_LongNameId is required".

We would like to set a custom validation message somehow, such that it simple says "'Name' is required", but cannot find a way via the grid APi or kendo validator to set this message. The conditional-logic nature of the rule plus the fact that we require In-Cell grid editing also makes this difficult to implement via validation rules.

How can we modify/change this validation message?

When converting an existing application to use Bootstrap 4, I spent a fair amount of time trying to figure out restore right-align to menu items, so I thought I would share what I found.

Basically, it is as simple as adding the new Bootstrap class "ml-auto" to the first menu item that you wish to be right-aligned; if there are additional menu items added after that one, they too will be right-aligned, but do not need to have the class added.

I am using a SiteMap to build my menu, so I have added my own attributes to the SiteMap (see image) to configure this and other characteristics, e.g. icons. The Menu itself is added as a Partial View, and the partial contains the logic to add the custom configurations in the BindTo method (see image).

Additionally, I am using the responsive panel to toggle the menu to vertical below a breakpoint, so in my panel implementation I check the window width to remove or add the "ml-auto" class to control the display, i.e. remove the right alignment during vertical orientation and restore it when horizontal (see image)

Hope this helps someone...

I'm converting a legacy form to Telerik UI, DropDownListForm "onchange" event works without changing anything while the NumericTextBoxFor "change" and "spin" events don't work, do you know why? Here is the relevant source code of my view:

Hello,

I need to reload the grid based on a  selection from a drop-down list.  I don't want to pre-load the grid and then filter, I only want  the grid to be populated after a change in selected value.
I have the drop-down list, and  the onChange event set up and working, the problem i am having is with the grid, its not re-loading or re-freshing with the data that is returned and i don't know why. Here is my code.

Index.cshtml

And here is the controller class

Im trying to make a Grid with inCell editing with a DropdownList in one cell.

The DropDownList is not shown correcty. When i click the cell i see a textfield for the id and the name.

I have a set of data where for any given date, there is a number for each of five geographic regions. When I try to put this data in a pie chart, I get 5n different series in my pie chart, where n is the number of days of data. I just want the chart to add all the data for each region, no matter how many days, so that I just have five different series.

I've been scouring the documentation and forums for hours, but the only lead is Pie Chart Data Aggregates, which is only for the jQuery version of Kendo. I'm trying to get this to work for MVC, but the documentation for MVC Aggregates is completely unhelpful. How can I get the functionality I'm looking for?
