Telerik Kendo MVC Grid child template get default value from parent

c#, kendo-asp.net-mvc, razor, telerik

Solution

Try adding a JavaScript function to handle the Save event

.Events(e => e.Save("save"))

in order to set the parent ID:

function save(e) {
  var parentGrid = $("#grid").data("kendoGrid");                        
  var parentRow = e.container.closest(".k-detail-row").prev(".k-master-row");                        
  var parentDataItem = parentGrid.dataItem(parentRow);

  e.model.set("CodeTypeId", parentDataItem.Id);
}

Problem

Hi I am editing in Kendo MVC Razor child template, I need to set the default value for the item id from the parent. It works if the property I try to set is a string, but not if it is an int. See the comment in the code below. If it is not possible to do this, can someone please suggest a workaround? Thanks. ``` @using Harpoon.DomainLogic @using Kendo.Mvc.UI @{ ViewBag.Title = "Index"; } <h2>Index</h2> @(Html.Kendo().Grid<UserStandardCodeType>().Name("grid") .DataSource(dataSource => dataSource.Ajax().Read(read => read.Action("GetUserStandardCodesTypes_Ajax", "UserStandardCode"))) .Columns(columns => { columns.Bound(usct => usct.InternalCode); columns.Bound(usct => usct.PresentationName); columns.Bound(usct => usct.Description); }) .ClientDetailTemplateId("client-template") ) <script id="client-template" type="text/x-kendo-template"> @(Html.Kendo().Grid<UserStandardCode>().Name("grid_#=Id#") // make sure the Name is unique .Columns(columns => { columns.Bound(usc => usc.InternalCode); columns.Bound(usc => usc.PresentationName); columns.Bound(usc => usc.Description); columns.Bound(usc => usc.IsEnabled); columns.Command(commands => { commands.Edit(); commands.Destroy(); }).Title("Commands").Width(200); }) .DataSource(dataSource => dataSource.Ajax() .Read(read => read.Action("GetUserStandardCodes_Ajax", "UserStandardCode", new { CodeTypeId = "#=Id#" })) .PageSize(2) .Model(model => { model.Field(usc => usc.CodeTypeId).DefaultValue("#=Id#"); // this line fails converting from string to int model.Id(usc => usc.Id); // specify the unique id column }) .Create(create => create.Action("CreateUserStandardCode_Ajax", "UserStandardCode")) .Update(update => update.Action("UserStandardCodes_Ajax", "UserStandardCode")) .Destroy(destroy => destroy.Action("UserStandardCodes_Ajax", "UserStandardCode")) ) .Pageable() .ToolBar(toolbar => toolbar.Create()) .Editable(editable => editable.Mode(GridEditMode.InLine)) .ToClientTemplate() ) </script> ```
