Bug report

In the Less themes the textboxes and the other editors (e.g., NumericTextBox) in the popup of the Grid are misaligned. The rendering of the textboxes in the MVC and Core Grid is different when compared to the Kendo UI for jQuery Grid.

Reproduction of the problem

Reproducible in the Popup Editing demos (Core and MVC).

1. Click the "Edit" button in a random row.
2. Inspect the Product Name Textbox in the browser

Current behavior

The width of the TextBox does not match the width of the NumericTextBox.

The rendering differs:

<span class="k-widget k-textbox k-valid" style=""><input data-val="true" data-val-required="The Product name field is required." id="ProductName" name="ProductName" value="" data-role="textbox" aria-disabled="false" class="k-input k-valid" autocomplete="off" data-bind="value:ProductName" style="width: 100%;"></span>

vs

<input type="text" id="ProductName" name="ProductName" title="Product Name" required="required" autocomplete="off" data-bind="value:ProductName" class="k-textbox k-valid">

Expected/desired behavior

Identical rendering and alignment.

Environment

• Kendo UI version: 2021.2.511
• jQuery version: x.y
• Browser: [all]

Bug report

Reproduction of the problem

Reproducible in:
https://demos.telerik.com/aspnet-mvc/grid/editing-inline
and
https://demos.telerik.com/aspnet-core/grid/editing-inline

1. Put a row in edit mode.
2. Inspect the input in the ProductName column

Current behavior

The input does not have a title attribute or label.

Expected/desired behavior

The input should either have a title attribute, like in the Kendo UI for jQuery Grid, or since we use a TextBox component as editor in MVC and Core, a label should be rendered.

Environment

• Kendo UI version: 2021.2.616
• jQuery version: x.y

I've been using the "Change" event to handle a Single Row Selection grid as that seems to be the event to use to determine when the user selects a row.

I just tried adding "persistSelection(true)" to my grid but it seems to be triggering a change event when I switch to another page and back to the previous page, or do an external $(this).data('kendoGrid').dataSource.read() on the grid.

How can I only get a change event when the USER selects a row, not the persistedSelection selecting the row?

Or at least detetect where it came from it in my Change event?

Thanks,

Bryan

Bug report

When .Navigatable() is enabled, the Grid renders an aria-describedby attribute in each td element. The value of the attribute should match the id value of the respective column header. This works for standard columns bound to fields in the data, but doesn't work for a selectable column:

columns.Select();

The selectable column header element (th) does not render an id. The td elements of that column render an aria-describedby attribute, the value of which does not match any element id. This causes an accessibility issue (Ticket ID: 1530928).

Reproduction of the problem

Reproducible with the MVC helper:

@(Html.Kendo().Grid<TelerikMvcApp1.Models.OrderViewModel>()
	.Name("grid")
	.Columns(columns =>
	{
		columns.Select();
		columns.Bound(p => p.OrderID).Filterable(false);
		columns.Bound(p => p.Freight);
		columns.Bound(p => p.OrderDate).Format("{0:MM/dd/yyyy}");
		columns.Bound(p => p.ShipName);
		columns.Bound(p => p.ShipCity);
	})
	.Pageable()
	.Navigatable()
	.Scrollable()
	.HtmlAttributes(new { style = "height:550px;" })
	.DataSource(dataSource => dataSource
		.Ajax()
		.PageSize(20)
		.Read(read => read.Action("Orders_Read", "Grid"))
	)
)

Current behavior

The selectable column header element (th) does not render an id.

Expected/desired behavior

The selectable column header element (th) renders an id that matches the aria-describedby attribute value of the td elements in the column.

        .ProxyURL(Url.Action("Excel_Export_Save", "Grid"))
    )
)

For a sample project, contact Ivan Danchev or Georgi Yankov.

Reproduction of the problem

If one of the columns (e.g. Field6) has a long header title calling the autoFitColumn and passing the column to it does not properly resize the column. The column remains narrow and its header text remains cut off.

Similarly, the method does not have the expected effect on columns with shorter text in the header, i.e. they remain wide instead of shrinking to the text length.

Current behavior

Incorrect column resizing.

Expected/desired behavior

Correct column resizing.

Hi.

I'd like to request the ability to sort on multiple columns of a grid, allow unsorting a column, but the grid must have at least one columns sorted.

An exception is thrown when calling `ToDataSourceResult` from the `Kendo.DynamicLinq` library if there are no columns sorted:

System.NotSupportedException: The method 'Skip' is only supported for sorted input in LINQ to Entities. The method 'OrderBy' must be called before the method 'Skip'

Thank you.

Hello, 

I think there is a bug with the DataTimeOffset field when used in a Grid. It cannot display correctly and is showing something like /Date(1364927400000)/. I have to retrieve my data from database as DateTimeOffset format and then use a new ViewModel to convert the DateTimeOffset values to DateTime values. This is really annoying.

Could you let me know if there is a way a DateTimeOffset field can be supported in the grid? Sometimes you do have to display the time zone info.

I hope this can be fixed in a future release.

Thanks,

Sam

When I use a grid, I can enable Filterable and the column shows me when I am filtering it; however if I enable ColumnMenu I have no indication if I am filtering on that column.  We've used a work around to handle this state ourselves, but its ugly and I think this should be part of the core product.

@(Html.Kendo().Grid<ShipmentGrid>()
  .Name("grid")
  .AutoBind(false)
  .Columns(columns =>
  {
  columns.Template(@<text></text>).Width(50).Title("PDFs").ClientTemplate($"<a href='javascript:" + jsPage + $".openDocumentWindow(#=AccountId#, #=OrderNumber#, #=OrderLineId#, #=OrderLineNumber#)'><img src={Url.Content("~/Content/images/pdficon_small.png")} /></a>");
  columns.Bound(m => m.CustomerName).Width(200).Title("Customer").HeaderTemplate("Customer <span style='float:center' class='k-icon k-i-filter'></span>").Filterable(f => f.Multi(true).Search(true)).Sortable(true);
  columns.Bound(m => m.PurchaseOrderNumber).Width(100).Title("PO").HeaderTemplate("PO <span style='float:center' class='k-icon k-i-filter'></span>").Filterable(f => f.Multi(true).Search(true)).Sortable(true);
  })
  .HtmlAttributes(new { style = "font-size:0.85em;" })

  .ColumnMenu()
  .Reorderable(reorder => reorder.Columns(true))

Hi Viktor,

We are looking for functionality of Context Menu on Columns of Kendo MVC grid.

We want various column selection on grid header.

Please help us to get this feature.

Regards

Supriya

Good Day,


I have a custom CSS CLASS that renders the background-color of the grids TABLE ROW to 'yellow'.  

• tr.background-color-yellow td { background-color: #FFFFCC; }

For example...the above CSS CLASS would 'color' the backgrounds of a TR's set of TD's.

<!-- Here is an example of the initial HTML containing the custom CSS CLASS  -->
<tr data-uid="7044a8d8-2946-43f4-9f94-01bff52d2800" role="row" class="background-color-yellow">
	<td role="gridcell">11</td>
	<td role="gridcell">1111</td>
	<td role="gridcell">111</td>
	<td role="gridcell">111</td>
	<td role="gridcell">111</td>
	<td role="gridcell">111</td>
	<td class="k-command-cell" role="gridcell">
		<a role="button" class="k-button k-button-icontext k-grid-edit" href="#">
			<span class="k-icon k-i-edit"></span>Edit 
		</a>
		<a role="button" class="k-button k-button-icontext k-grid-delete" href="#">
			<span class="k-icon k-i-close"></span>Delete
		</a>
	</td>
</tr>

THE ISSUE
When using inline-editing on the grid...pressing the CANCEL button wipes-out & replaces any-and-all custom CSS tags in the TR.

<!-- Here is an example of the initial HTML AFTER PRESSING CANCEL...notice the custom CSS CLASS is gone -->
<tr data-uid="7044a8d8-2946-43f4-9f94-01bff52d2800" role="row">
	<td role="gridcell">11</td>
	<td role="gridcell">1111</td>
	<td role="gridcell">111</td>
	<td role="gridcell">111</td>
	<td role="gridcell">111</td>
	<td role="gridcell">111</td>
	<td class="k-command-cell" role="gridcell">
		<a role="button" class="k-button k-button-icontext k-grid-edit" href="#">
			<span class="k-icon k-i-edit"></span>Edit 
		</a>
		<a role="button" class="k-button k-button-icontext k-grid-delete" href="#">
			<span class="k-icon k-i-close"></span>Delete
		</a>
	</td>
</tr>

THE WORK AROUND
This bug causes the following kinds of work-around...which I feel is unacceptable.

this.on = {
	cancel: {
		grid: function (e) {

			var isTemplatedRow = e.model.IsTemplatedRow;
			if (isTemplatedRow === false) {

				// HACK: Kendo overwrites the (tr) rows ENTIRE SET of CSS CLASSES after a 'cancel' is triggered
				var uid = e.container.data().uid;
				var $context = $(e.container.context);
				setTimeout(function () {

					// Add the expected class back-in
					var $ele = $('tr[data-uid=' + uid + ']', $context)
					$ele.addClass('background-color-yellow');
				}, 400);
			}
		}
	}
};

JWT Token authentication has become very popular and one of the main tools to provide authorization and authentication.
JSON Web Token (JWT) is an open standard (RFC 7519) that defines a compact and self-contained way for securely transmitting information between parties as a JSON object. In authentication, when the user successfully logs in using their credentials, a JSON Web Token will be returned. 

Whenever the user wants to access a protected route or resource, the user agent should send the JWT, typically in the Authorization header using the Bearer schema. This can be, in certain cases, a stateless authorization mechanism. The server's protected routes will check for a valid JWT in the Authorization header, and if it's present, the user will be allowed to access protected resources. If the JWT contains the necessary data, the need to query the database for certain operations may be reduced, though this may not always be the case.

It would be really helpful to have a built in functionaly ".Authorization(token)" that adds an authorization header to all the requests made by the grid.

As the title says, I'm getting script errors when attempting to perform a delete function with an MVC grid when in MobileMode.Phone.  The attached project will illustrate the problem.  Just run it and select delete button for one of the items in the far right column.  A popup will appear, but don't click either of the buttons on it yet.  Inspect the html with whatever browser you use (I'm using chrome so I just right click and choose select).  There will be a "Cannot read property 'data' of undefined" error.  If you then click the "Delete" button, you'll get a "Cannot read property 'resolve' of undefined".  Then click on the "Cancel" button and you'll get "Cannot read property 'reject' of undefined".  I'll attach a pic showing these errors.

I need to be able to utilize my grid in mobile phone mode and delete items.  Please help with this.

Also, to get this sample project small enough, I removed the files from the MobileSaveError\lib\KENDOUIMVC\2020.3.915.545 folder.  I figure you can replace those easily enough.  Is that the right thing to do in this case?  I thought maybe I could remove the items in the Packages folder as NuGet/VS will usually restore those.  But wasn't 100% sure on that.  So if you can tell me or link me to an article about what we can remove to shrink the project size for samples when we need to send them, that would be great.

Thank you,
Steven

### Bug report

When the GroupPaging option is enabled and the grid is bound to a DataTable, the server error "Value cannot be null" is observed.


### Environment

* **Kendo UI version:** 2020.3.915
* **jQuery version:** 1.12.4
* **Browser:** [all] 

I downloaded the latest version of Kendo UI (Version: 2020.1.406) for MVC and upgraded my project to refer the latest JS, CSS and Kendo.MVC (2020.1.406.545).

NoRecords method is behaving differently in the latest version. While fetching records in progress, it displays the 'No record found' message even before completion of the action method. Please see the below image:

It was not happening in the version 2018.2.516, it was showing the 'No record found' message after completion of the action method and only if there is 0 row returned.

Below is the code of Student.cshtml view:

Bug report

Using server binding does not render the NoRecords message for the Grid

Reproduction of the problem

	@(Html.Kendo().Grid(new List<Product>())    
		.Name("Grid")
		.Columns(columns => {
			columns.Bound(p => p.ProductID).Groupable(false);
			columns.Bound(p => p.ProductName);
			columns.Bound(p => p.UnitPrice);
			columns.Bound(p => p.UnitsInStock);
		})
		.NoRecords("No records found.")
		
		.Pageable()
		.Sortable()
		.Scrollable() 
		.DataSource(d=>d.Server())
		.Filterable()
		.Groupable()
	)

Workarond

A possible workaround is to use local binding by setting the AJAX binding in the DataSource, but keep the initial server binding:

	@(Html.Kendo().Grid(new List<Product>())    
		.Name("Grid")
		.Columns(columns => {
			columns.Bound(p => p.ProductID).Groupable(false);
			columns.Bound(p => p.ProductName);
			columns.Bound(p => p.UnitPrice);
			columns.Bound(p => p.UnitsInStock);
		})
		.NoRecords("No records found.")
		
		.Pageable()
		.Sortable()
		.Scrollable() 
		.DataSource(d=>d.Ajax().ServerOperation(false))
		.Filterable()
		.Groupable()
	)

Environment

• Kendo UI version: 2017.3.1026

Bug report

The responsive pager of the grid is shown when the width of the window is a few pixels above 1024 but less than 1035.

Reproduction of the problem

Dojo sample for reproduction:

https://dojo.telerik.com/oNejEYOz

1. Resize the browser to be around 1025 pixels. Just after showing the full pager, refresh the page.

2. The responsive pager is shown.

Expected/desired behavior

The full pager should be shown.
