Hi,

We have a grid with a detail template containing a tabstrip - much like the demo at https://demos.telerik.com/aspnet-mvc/grid/detailtemplate .

Three tabs got their content from calling controller actions which returned different Partial views.

We do not need to show multiple tabs now - we only need to show one so do not need the tabstrip control.

How can we keep the same method of getting the detailtemplate content from a controller action partialview without the tab strip?

The data is a single model - not a listing - so not suited to a grid or listview.

Many Thanks.

Hi all,

I am trying to make an HtmlHelper to create sub grids by passing an ISubGridBuilder which will contain the construction detail of my sub grid.

Example:

The problem is that at runtime I get a reference error:

How can I add the ParentId parameter on the routeValues for the controller call.

Thank you!

Hello,

We have an MVC project that uses the Kendo MVC grid to return well data records.  Because we use paging and can return several thousand records, we're using Ajax with server side paging like this (abbreviated):

@(Html.Kendo().Grid<GroundWater.Models.GroundWaterSearchResult>()
          .Name("grid")
          .Columns(columns =>
          {
              columns.Bound(p => p.well_id).Title("Well ID").Width(75).HtmlAttributes(new { style = "text-align: right;" });
              columns.Bound(p => p.Well_Name).Title("Well Name").Width(105).Locked(true);
              columns.Bound(p => p.Permit).Title("PermitNo").Width(90);
              columns.Bound(p => p.Well_Depth).Title("Well Depth").Width(64).HtmlAttributes(new { style = "text-align: right;" });
              columns.Bound(p => p.Water_Level_Depth).Title("Water Level Depth").Width(66).Format("{0:n2}").HtmlAttributes(new { style = "text-align: right;" });
               columns.Bound(p => p.Measurement_By).Title("Measurement By").Width(111);
              columns.Bound(p => p.publication_name).Title("Publication Name").Width(93);
              columns.Bound(p => p.Elevation).Title("Elevation").Width(78).Format("{0:n2}").HtmlAttributes(new { style = "text-align: right;" });
              columns.Bound(p => p.Elevation_Accuracy).Title("Elevation Accuracy").Width(121);
              columns.Bound(p => p.Top_Perforated_Casing).Title("Top Perforated Casing").Width(84).HtmlAttributes(new { style = "text-align: right;" });
              columns.Bound(p => p.Bottom_Perforated_Casing).Title("Bottom Perforated Casing").Width(85).HtmlAttributes(new { style = "text-align: right;" });
              columns.Bound(p => p.Base_of_Grout).Title("Base of Grout").Width(65).HtmlAttributes(new { style = "text-align: right;" });
              columns.Bound(p => p.Contact).Title("Owner").Width(130);
              columns.Bound(p => p.DIV).Title("DIV").Width(54).HtmlAttributes(new { style = "text-align: right;" });
              columns.Bound(p => p.WD).Title("WD").Width(54).HtmlAttributes(new { style = "text-align: right;" });
              columns.Bound(p => p.County).Title("County").Width(69);
              columns.Bound(p => p.basin).Title("Designated Basin").Width(91).HtmlAttributes(new { style = "text-align: right;" });
              columns.Bound(p => p.Management_District).Title("Management District").Width(91);
          })
          .Pageable(pager => pager
              .PageSizes(true)
              .PageSizes(new int[] { 10, 20, 50, 100 }))
          .Sortable(sorting => sorting.AllowUnsort(false))
          .Scrollable(scroll => scroll.Height(500))
          .Filterable()
          .Resizable(resize => resize.Columns(true))
          .Reorderable(reorderable => reorderable.Columns(true))
          .ColumnMenu()
          .DataSource(dataSource => dataSource
              .Ajax()
              .Read(read => read.Action("Wells_Read", "GroundWaterSearch").Data("filterData"))
              .ServerOperation(true)
              .PageSize(50)
          )
)

And the JS 

<script>
    function filterData() {
        return {
            Publication: document.getElementById('publicationArea').value
            //WellName: document.getElementById('wellname').value,
            //StartDate: document.getElementById('startdate').value,
            //EndDate: document.getElementById('enddate').value,
            //ContrArea: document.getElementById('contributingarea').value,
            //WaterDistrict: document.getElementById('waterdistrict').value
            //........ up to 10 additional fields
        };
    }
</script>

And the Controller looks like this:

 public ActionResult Wells_Read([DataSourceRequest]DataSourceRequest request, string Publication, ......add more parameters)
        {
            List<string> criteria = new List<string>();
            GetPublicationArea(Publication, criteria);

           .... additional search criteria

            var tempCalls = CallMgrData.GetGroundWaterLevelsResult(criteria);
            List<GroundWaterSearchResult> values = tempCalls.ResultSet.Select(x => ModelMapper.Map<GroundWater, GroundWaterSearchResult>(x)).ToList();
            DataSourceResult result = values.ToDataSourceResult(request);
            return Json(result);
        }

My question is, what are my options for returning the additional parameters to the Controller?  The View contains complex search criteria (including strings, numbers, and datetime) so I need to return up to 16 parameters from the DataSource.   I don't really want to keep adding a long list of parameters (many would or could be null).  I would rather return a single object to the controller.  I read somewhere I can pass a class object or maybe a json string as the DataSource.Data?  Any help would be appreciated.  Thanks

Hi I have need to display multiple dynamic grid on single page. I created partial view with dynamic grid binding and passing model and method name to bind data from view. First grid displays data and call data read action but rest of the grid do not display data or call method. It shows column names but no data. 

This is partial view

In main view I am passing list of datatable and in partial view it is getting datatable from ajax call. I have created 3 separate method (ReadData1, ReadData2, ReadData3) in RanData controller.
Thanks in advance.

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?
