Hi

I have implemented below custom validation rule. It works but it triggers a controller method twice once on Edit of cell and once Closure of cell. I just wanted it to be triggered on closure of cell. Can you please help me on this. Thank you

My property in in my Model is as below

 [Remote("IsUniqueDisplayName", "Bookmark", AdditionalFields = "DocumentTypeId", ErrorMessage = "Display Name must be Unique.")]
 public string DocumentTypeSortNameTitle { get; set; }

Custom validation rule implementation in javascript as below

 (function ($, kendo) {
        $.extend(true, kendo.ui.validator, {
            rules: {
                mvcremotevalidation: function (input) {
                    if (input.is("[data-val-remote]") && input.val() != "") {
                        var remoteURL = input.attr("data-val-remote-url");
                        var valid = true;
                        var td = input.parent('td');
                        if (td.hasClass("k-dirty-cell")) {
                            var found = false;
                            $.ajax({
                                async: false,
                                url: remoteURL,
                                type: "GET",
                                dataType: "json",
                                data: validationData(input, this.element),
                                success: function (result) {
                                    found = result;
                                    if (found)
                                        valid = false;
                                    else {
                                        valid = true;
                                    }
                                },
                                error: function () {
                                    valid = false;
                                }
                            });
                        }
                       return valid;
                      
                    }

                    return true;
                }
            },
            messages: {
                mvcremotevalidation: function (input) {
                     return input.attr("data-val-remote");
                  //  return "Display Name must be Unique";
                }
            }
        });

        function validationData(input, context) {
            var grid = $("#BookmarkDoctypeGrid").data("kendoGrid");
            var currentData = grid.dataSource.data();
            var uid = $("#BookmarkDoctypeGrid").find('.k-edit-cell').parent('tr').data('uid');
            var dataItem = grid.dataSource.getByUid(uid);
            var documentTypeId = dataItem.DocumentTypeId;
            var fields = input.attr("data-val-remote-additionalFields").split(",");
            var name = input.prop("name");
            var prefix = name.substr(0, name.lastIndexOf(".") + 1);
            var fieldName;
            var data = {};
            for (var i = 0; i < fields.length; i++) {
                fieldName = fields[i].replace("*.", prefix);
                if (fieldName == 'DocumentTypeId') {
                    data[fieldName] = documentTypeId;
                } else
                    {
                    data[fieldName] = $("[name='" + fieldName + "']", context).val();
                }
            }            
            return data;
        }
    })(jQuery, kendo);

Hi,


I have a dropdown list binding to a datasource with duplicate records. Is there any way I  can remove the duplicate items in the dropdown list? I don't want to remove the duplicate records in the datasource because it is shared by a grid. Thanks.

I have wired up a simple grid with some bound columns and one of those columns I'm trying to create a hyperlink.  Here is my code:


The second column is the column where I'm attempting to show the hyperlink.  Now, when I render the page, I can see the hyperlink for a split second before it disappears and I just see the text is supposed to be included in the link, but it is not linked after that.

Now, here's the funny thing:  If I remove the reference to kendo.aspnetmvc.min.js in my BundleConfig.cs file, the hyperlinks show up just fine, however, I get a "Script not included" error if I do this.

Any idea what I'm doing wrong?

Is anyone else having issues with the standard filtering functionality on a ForeignKey column with the latest release?  After upgrading, I noticed in a project of mine the Filter button was not causing a datasource read, and also went to the demo page (http://demos.telerik.com/aspnet-mvc/grid/foreignkeycolumn) and was getting the same behavior across different browsers (no sign of any Javascript errors in various browser debuggers).

From that demo page, if I go to filter the Category column on "Beverages", no filter event seems to fire.  However, if I go to the the Unit Price column and hit the "Clear" button and then go back to the Category column and filter on "Beverages" again, it properly filters.

Seems to affect the Kendo UI version of the demo the same way from what I can see

Is there a way to only allow the user to control the selectable file types?

I know I can get the information once they select the file but I'd prefer to filter the list to only .pdf, or whatever.

I have issues in using the spinners of numeric textbox in IE10(Standards mode as well as compatiblity mode)
but this doesn't work in the demo site either

http://demos.telerik.com/aspnet-mvc/numerictextbox/index

Any workarounds for this ?

I have a form that has a standard datepicker that highlights specific dates.  Based on the example in the demo section, this is what the control is set up as:

In the Javascript, I have this:


The above code works; the ajax call returns a collection of strings that are all parsed into date objects and pushed in the the events array.

However, at any given time, the collection of dates can change depending on the users input.  However, once the datepicker control is initialized, changing the dates array doesn't refresh the highlighted dates in the control (in effect, once the MonthTemplate is rendered, it never reloads).

Is there a way to dynamically change the highlighted dates client side?

Hello Telerik Team,

I want my kendo grid built in Asp.Net MVC 4 receive any object model, in other words, dynamic. The action method of my controller not show errors, but the data not displayed in kendo grid. Any suggestions?

View:

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<dynamic>" %>
 <% Html.Kendo().Grid<dynamic>()
    .Name("GridTeste")
    .Columns(columns =>
    {
        if (Model != null)
        {
            foreach (var x in Model)
            {
                 columns.Bound(x.Value, x.Key.ToString()).Title(x.Key).Encoded(false);
            }
        }
    }
    )
         .DataSource(datasource => datasource
         .Ajax()
         .Read(read => read.Action("CarregarDados", "ImportacaoTabelaPropria", new { acao = "Brasindice", ajuste = "", nova_validade = "" }))
         )
        .Navigatable()
        .Scrollable()
        .Selectable()
        .HtmlAttributes(new { style = "width:100%;height:400px;", id = "GridTeste" })
        .Render();
 %>

My Action in Controller: 

        public ActionResult CarregarDados(string acao, string ajuste, string nova_validade, [DataSourceRequest] DataSourceRequest request)
        {
            PreencherTabelaPropria tabela_propria = new PreencherTabelaPropria();
            PreencherBrasindice bras = new PreencherBrasindice();
            Dictionary<string,System.Type> colunas = new Dictionary<string,Type>();
            if (acao.Equals("Tabela propria"))
            {
                return Json(tabela_propria.PreencherTabelaPropriaValores(), JsonRequestBehavior.AllowGet);
            }
            if (acao.Equals("Brasindice"))
            {
                if (bancoBrasindice != null)
                {
                    if (!String.IsNullOrEmpty(ajuste))
                    {
                        foreach (var x in bancoBrasindice)
                        {
                            x.Ajuste_liberado = ajuste;
                            if (!String.IsNullOrEmpty(nova_validade))
                                x.Nova_validade = DateTime.Parse(nova_validade);
                        }
                        return Json(bancoBrasindice, JsonRequestBehavior.AllowGet);
                    }
                }
                else
                {
                    List<ImportacaoBrasindiceModel> brasindice = bras.PreencherBrasindiceValores();
                    //atualizar o modelo com os valores de ajuste e validade
                    foreach (var x in brasindice)
                    {
                        x.Ajuste_liberado = ajuste;
                        if (!String.IsNullOrEmpty(nova_validade))
                            x.Nova_validade = DateTime.Parse(nova_validade);
                    }
                    bancoBrasindice = brasindice;
                }
                Dictionary<string, System.Type> colunas2;
                PropertyInfo[] propriedades = typeof(ImportacaoBrasindiceModel).GetProperties();
                colunas2 = new Dictionary<string, Type>();
                foreach (PropertyInfo x in propriedades)
                {
                    colunas.Add(x.Name, x.PropertyType);
                }
                //return PartialView("~/Views/ImportacaoTabelaPropria/TesteGridParcial.ascx", Json(bancoBrasindice, JsonRequestBehavior.AllowGet));
                return Json(bancoBrasindice.ToDataSourceResult(request), RenderPartialViewToString("~/Views/ImportacaoTabelaPropria/TesteGridParcial.ascx", colunas), JsonRequestBehavior.AllowGet);

            }
            return Content("");
        }

My method to convert Partial View to string: 

protected string RenderPartialViewToString(string viewName, object model)
        {
            if (string.IsNullOrEmpty(viewName))
                viewName = ControllerContext.RouteData.GetRequiredString("action");

            ViewData.Model = model;

            using (StringWriter sw = new StringWriter())
            {
                ViewEngineResult viewResult = ViewEngines.Engines.FindPartialView(ControllerContext, viewName);
                ViewContext viewContext = new ViewContext(ControllerContext, viewResult.View, ViewData, TempData, sw);
                viewResult.View.Render(viewContext, sw);

                return sw.GetStringBuilder().ToString();
            }
        }

I am using kendo color picker and its doesn't work fine in IE10(standard mode as well as compatibility mode)

I later found this issue in demo either
http://demos.telerik.com/aspnet-mvc/colorpicker/index 

I am not able to select any color from the color picker in IE10

I am using win 7 64 bit environment.
Any workaround for this ?
