[Solved] Subgrid is not loading the data

Hi All,

I am using Kendo MVC subgrid with client template, and initially its working fine but since few days back subgrid is not loading any data.

Here is my code for Grid. In my case when expanding sub grid its loading column but not the data and also dont seen any event for data load.

<h3 class="nvs">Search Results</h3>

@(Html.Kendo().Grid<DealInfo>()

.Name("SalesGrid")

.Columns(columns =>

{

columns.Template(@<text></text>).ClientTemplate("<input type='checkbox' class='master'/>").Width(30);

columns.Bound(e => e.Nbr).Title("Nbr").Width(160);

columns.Bound(e => e.Name).Title("Name");

columns.Bound(e => e.Name1).Title("Name1");

columns.Bound(e => e.JobTYpe).Title("JobType");

})

.Sortable()

.Scrollable()

.ClientDetailTemplateId("template")

.DataSource(ds => ds

.Ajax()

.PageSize(10)

.Read(r => r.Action("Action", "Controller").Data("jsview.GetSearchCriterion"))

)

.HtmlAttributes(new { style = "height:500px;" })

.Pageable(p => p

.Numeric(true)

.PageSizes(new[] { 10, 20, 50 })

.PreviousNext(true)

)

<div>

<script id="template" type="text/kendo-tmpl">

@(Html.Kendo().Grid<DealOrdersModel>()

.Name("grid_#=Nbr#") // template expression, to be evaluated in the master context

.Columns(columns =>

{

columns.Bound(o => o.OrderNbr).Title("Order Number").HeaderHtmlAttributes(new { style = "white-space:normal" });

columns.Bound(o => o.Date).Title("Date").Format("{0:MM/dd/yyyy}").HeaderHtmlAttributes(new { style = "white-space:normal" });

columns.Bound(o => o.Type).Title("Type").HeaderHtmlAttributes(new { style = "white-space:normal" });

columns.Bound(o => o.Type1).Title("Type1").Width(110);

})

.DataSource(dataSource => dataSource

.Ajax()

.PageSize(5)

.Read(read => read.Action("Action1", "Controller", new { Nbr = "#=Nbr#" }))

)

.Pageable()

.Sortable()

.ToClientTemplate()

)

</script>

</div>

How can I show DropDownList as the default column type in GridView initial loading for all rows ?

Hi,
I'd like to know how can I show DropDownList as the default control type for specific column in GridView control on its initial loading instead of showing the default label in each row for specific column.
I'm using in-cell edit mode and I followed your demos to show DropDownList for specific column by using ClientTemplate and ForeignKey Column Type ..Its working good, However, I'd like to show this DropDownList always for this columns in all rows in GridView initial loading not only when focus on the related cell.

MyView:

@(Html.Kendo().Grid<GIWebDemoApp.Models.ViewModels.ProductCategoryViewModel>()<br> .Name("grid"

)<br>    .Columns(columns =><br>    {<br>        columns.Bound(p => p.ProductName);<br>        columns.Bound(p => p.Category).ClientTemplate(

"#=Category.CategoryName#"

).Width(160);<br>        columns.Bound(p => p.UnitPrice).Width(120);<br>        columns.Command(command => command.Destroy()).Width(90);<br>    })<br>    .ToolBar(toolBar =><br>        {<br>            toolBar.Create();<br>            toolBar.Save();<br>        })<br>    .Editable(editable => editable.Mode(GridEditMode.InCell))<br>    .Pageable()<br>    .Sortable()<br>    .Scrollable()<br>    .HtmlAttributes(

new { style = "height:430px;" })<br> .DataSource(dataSource => dataSource<br> .Ajax()<br> .Batch(true)<br> .ServerOperation(false)<br> .Events(events => events.Error("error_handler"

))<br>        .Model(model =><br>        {<br>            model.Id(p => p.ProductID);<br>            model.Field(p => p.ProductID).Editable(

false);<br> })<br> .PageSize(20)<br> .Read(read => read.Action("GetAllProductsAndRelatedCategories", "Product"))<br> .Create(create => create.Action("AddProductsAndRelatedCategories", "Product"))<br> .Update(update => update.Action("UpdateProductsAndRelatedCategories", "Product"))<br> .Destroy(destroy => destroy.Action("RemoveProductsAndRelatedCategories", "Product"))<br> )<br>)

-----------------------------------------------

<p>public

ActionResult Manage()        </p><p>{            </p><p>PopulateCategories();  </p><p>

return View(); </p><p>}</p>

private void PopulateCategories()<br> {<br> var dataContext = new

NORTHWNDEntities();<br>            var categories = dataContext.Categories<br>                        .Select(c =>

new

CategoryViewModel<br>                        {<br>                            CategoryID = c.CategoryID,<br>                            CategoryName = c.CategoryName<br>                        })<br>                        .OrderBy(e => e.CategoryName);<br><br>            ViewData[

"categories"] = categories;<br> <br> }

DropDownListFor SelectedIndex

I'm working with Kendo UI on an MVC application. We have a grid and when the user opens the row for editing we have a dropDownList that holds company names. I'm trying to get the DDL to default to the company name that's pertinent to the row.

Here's the column code:

columns.Bound(e => e.company_business_name).Width(220).Title("Company")

.EditorTemplateName("CompanyName");

and here's the editorTemplate code:

@model string

@(Html.Kendo().DropDownListFor(m => m)

.DataTextField("Text")

.DataValueField("Value")</p><p>

.BindTo((System.Collections.IEnumerable)ViewData["Companies"])

)

and the method that fills the DDL:

private void PopulateCompanies()

{

var companyList = new List<SelectListItem>();

if (!string.IsNullOrEmpty(Session["Companies"] as string))

{

companyList = (List<SelectListItem>)Session["Companies"];

}

else

{

companyList = new DataAccess().GetCompanies(CurrentSettings.getUser().userId);

CacheCompanies(companyList);

}

ViewData["Companies"] = companyList;

}

The dropDownList is populating, and displays when I click edit, but the selected value is blank. How can I set it to the value that was in the grid when it was in display mode?

[Solved] Grid extension method

Hello,

I want to create a helper method that wraps a Kendo UI widget as described here:
http://docs.telerik.com/kendo-ui/aspnet-mvc/helpers/grid/faq#how-to-create-helper-methods-rendering-predefined-widgets-i-can-further-configure

using Kendo.Mvc.UI;

using Kendo.Mvc.UI.Fluent;

using Microsoft.AspNetCore.Mvc.ViewFeatures;

namespace Gpdb.Helpers

{

public static class HtmlHelperExtensions

{

public static GridBuilder<T> MyKendoGrid<T>(this HtmlHelper helper, string name)

where T : class

{

return helper.Kendo().Grid<T>()

.Name(name)

.Groupable()

.Pageable()

.Sortable()

.Scrollable()

.Filterable()

.Pageable();

}

but this doesn't work because of the following error (see attached Picture) - what I'm missing?

Upgrade Wizard is Horrible

VS2015 keeps nagging me to update my project with the latest version of Telerik MVC. Currently I'm using 2016.2.607. I got tired of the nagging, so I used the Upgrade wizard, and absolutely nothing in my code worked anymore. It was by far one of the most horrible upgrade experiences. What is the best way to update this to the latest version without having to basically re-write everything?
