Bug report

Reproduction of the problem

Dojo example: https://dojo.telerik.com/InUYAheR/4
Drag and drop a row from Grid2 to Grid1 by following the steps below:

1. Click and hold down the mouse button within a Grid2 row, just before its ID value or a little after it.
2. Drag the row to Grid1 and drop it over row 3 or row 4.

Current behavior

Grid1's first row values get updated, instead of the drop target row values. This is because e.target in the DropTarget's "drop" event does not return the actual target you drop over.
If you click and drag in the middle of the Grid2 row, drag it and drop it over a row in Grid1, the drag and drop functionality works as expected: e.target returns the correct target.

Expected/desired behavior

e.target should consistently return the target you drop over, regardless of where in the dragged row you have clicked.

Hi Team,

Bug Report

The Kendo UI Grid's toolbar with a template is not persisted when the Grid is loaded using setOptions. 

Reproduction of the problem

With a toolbar containing a template with server tags, the toolbar content will disappear.

Expected Behavior

The Grid should retain the toolbar with the HTML contained when using setOptions.

Environment

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

Thanks!

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 adding aggregation to the Kendo UI Grid Custom Ajax Binding Live Demo.

Thank you!

Implement stacking columns on smaller screens, e.g., https://docs.telerik.com/devtools/aspnet-ajax/knowledge-base/grid-stack-responsive-columns-on-small-screens

It would be great if we could use the built in column filtering on columns containing arrays.

Or at the very least have a workaround (which I have not been able to find on the site).

I understand that the current implementation relies on the data being flat, but support for the following situation would be great:

- Grid cell is bound to an array and a template is used to display character delimited data (ie. One, two, three, four).

- Column filtering will display multi select options for the data.

When using the Grid Endless Scrolling, is there a way to prevent the existing records from momentarily disappearing as the spinner appears?

Using endless scrolling on a large grid (full screen), the users eye tracks down the list as the mousewheel is turned. At the moment the next page is fetched, the view of the data is disrupted as the spinner appears and the data disappears. This can be quite jarring to the senses when browsing for a specific record in the list.

On a small grid such as that on the example page (https://demos.telerik.com/kendo-ui/grid/endless-scrolling-remote) it isn't quite as jarring on the senses, but with a large grid with many columns and rows, it can be very off-putting.

Ideally, if the existing records can remain opaquely visible in the background under the spinner whilst the next page of data is being retrieved, it would produce a much cleaner user experience.

We set up a grid that auto-filters a name field to "does not contain" and the value it excludes is "[DEACTIVATED]".  This column is also filtering out records that have a null in them if this filter is set.  I had to change the datasource to return an empty string instead.

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

Reported in: Ticket ID: 1524543. Reproducible in Chrome and Firefox. Not reproducible in Edge
Version 91.0.864.54.

Reproduction of the problem

Dojo example: https://dojo.telerik.com/iqUFarUV/3

1. Hide half of the columns (uncheck them in the column menu -> Columns)
2. Try to resize a column

Current behavior

On dragging the handle the column width automatically increases. Then if you try to decrease the width, you can't go past a certain width threshold.

Expected/desired behavior

The columns can be resized precisely, similarly to when their width is set in "px" instead of "%".

Environment

• Kendo UI version: 2021.2.616
• jQuery version: x.y
• Browser: [Chrome 91, Firefox 89]

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");

}

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.

The NumericTextBox renders two input elements. In a Grid inline editing scenario: https://demos.telerik.com/aspnet-mvc/grid/editing-inline  one of inputs of the NumericTextBox editor does not render a title and there is no label for the inputs. This causes an error for missing form element label in Html static analysis (Wave).

One way for this to be avoided could be using aria-labelledby attribute instead of title. The same aria-labelledby value will be assigned to both inputs pointing to a span or div that contains the input value. This way both inputs will have label and won't trigger the missing label error.
