In the Kendo UI for jQuery Grid, fields that are not editable are displayed as text (no input elements) in the Grid's popup editor. The MVC Grid displays all fields that are present in the view model it is bound to in its popup editor.

Implement an option to configure the editable fields, so that the behavior of the MVC Grid matches that of its Kendo UI counterpart.

Currently the ForeignKey column expects data to be loaded in it initially. This could be either local data or remote data.

For scenarios that involve using large data, it would be helpful if we can have more flexibility with the way data is loaded in the column's editor (e.g., DropDownList). For example, we want to use cascading ForeignKey editors. Once a selection is made in the first dropdown, the second cascades and is loaded with the respective data. This is not viable at the moment, because the data must be supplied to the ForeignKey column initially. If an empty collection is passed initially:

columns.ForeignKey(c => c.Field1, new List<SelectListItem>(), "Value", "Text").Width(100);

and the dropdown is then loaded with data after the Grid's Edit popup opens, the ForeignKey column will display the DataFieldValue as text, because no initial data has been provided.

An option to load data on demand would be a welcome performance enhancement.

I would like to be able to create .bindBoolColumn. I do not want extend the column itself.  I already have extensions for that.

Something like this:

GridBoundColumnBuilder<TModel> BoundBoolean<TValue>(Expression<Func<TModel, TValue>> expression)

public  GridBoundColumnBuilder<TModel> BoundBool<TValue>(Expression<Func<TModel, TValue>> expression)

{

     column = *place create column code here*;
     column.Width(90);
     column.clientTemplate("customtemplate");

}

When using template and no DataSource is set Grid NoRecords message is not rendered.

Reproduction of the problem

Define a 'No Records' with template similar to the following article example: https://docs.telerik.com/aspnet-mvc/html-helpers/data-management/grid/templates/no-records

@(Html.Kendo().Grid<Grid_Template.Controllers.GridModel>()
    .Name("Grid1")
    .NoRecords(n => n.Template("string HTML template, not centered"))
)

Current behavior

The default message for missing record is displayed: No records available.
"autoBind":false is applied to serialization

Expected/desired behavior

The message from the template is displayed: "string HTML template, not centered"

Workaround:
Add .DataSource(d => d.Ajax()) to the Grid configuration

@(Html.Kendo().Grid<Grid_Template.Controllers.GridModel>()
    .Name("Grid1")
    .NoRecords(n => n.Template("string HTML template, not centered"))
        .DataSource(d => d.Ajax())

)

Bug report

The Kendo UI Grid's Toolbar Template UI for ASP.NET MVC documentation displays an approach used for UI for ASP.NET Core. The ClientTemplate and ClientTemplateID are not available for UI for ASP.NET MVC.

Reproduction of the problem

Please try the approach used in the documentation. It is not available for UI for ASP.NET MVC.

Expected/desired behavior

Either include the approach for UI for ASP.NET MVC, or modify the documentation.

Environment

• Kendo UI version: 2022.2.510
• jQuery version: 3.6
• Browser: all

Hi Team,

I'd like to request adding aggregation to the Kendo UI Grid Custom Ajax Binding Live Demo.

Thank you!

Hi Team,

I would like to request better integration when grouping using a viewModel.  When grouping by defining the field in the group event using a model from EF, the Grid should continue to use the viewModel instead of the model's field.   This would provide the Grid's group templates to be retained. 

Please take a look at the following gif which shows the current behavior using the viewModel's RoomLocation field vs. the model's HomeRoom.RoomLocation. 

Thank you! 

Hi Team,

I'd like to request a similar example based on the virtualization of local data demo for UI for ASP.NET MVC.  

Thank you!

Bug report

Regression in R1 2023 SP1.

Reproduction of the problem

Set a HeaderTemplate in one of the following 3 ways.

columns.Bound(p => p.Freight).HeaderTemplate("<div title='Freight'>Freight</div>");

columns.Bound(p => p.Freight).HeaderTemplate(@<text>
<div title="Freight">Freight</div>
</text>);

columns.Bound(p => p.Freight).HeaderTemplate(@<div title="Freight">Freight</div>);

Current behavior

In the first scenario the error is:
System.NotSupportedException: Specified method is not supported. 

In the second and third scenario the error is:
Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

Expected/desired behavior

No exception thrown when the HeaderTemplate is set.

Environment

• Kendo UI version: 2023.1.314
• jQuery version: x.y
• Browser: [all]

### Bug report

The Grid columns do not expose the ClientTemplateHandler() method. It is available in Telerik UI for ASP.NET Core since version 2023.1.314.

### Reproduction of the problem

columns.Bound(p => p.IsAlwaysIncluded).ClientTemplateHandler("myColTemplate");

<script>
function myColTemplate(data) {
  return `<div>${data.IsAlwaysIncluded}</div>`
}
</script>

The ClientTemplateHandler() method must be exposed for the Grid columns.

### Environment

Telerik UI for ASP.NET MVC version: 2023.1.425
* **Browser: [all]

Add a class to cells in a sorted column (similarly to the .k-sorted class in a sorted column's <th> element) to distinguish them from cells in unsorted columns.
