I'm in the process of rewriting all Kendo components to use CSP compatible templates. I'm looking at https://docs.telerik.com/aspnet-core/html-helpers/template/overview which shows how we'd use TemplateComponentName() for popup editors and that we would need to rewrite everything in the popup editor to use Kendo Template's AddHtml or AddComponent methods.

Original:

<div class="mb-2 row required">
	@Html.LabelFor(model => model.FileName, new { @class = "col-sm-4 col-form-label fw-bold text-sm-end" })
	<div class="col-sm-6">
		@(Html.Kendo().TextBoxFor(model => model.FileName).HtmlAttributes(new { @class = "w-100" }))
	</div>
</div>

<div class="mb-2 row">
	@Html.LabelFor(model => model.FileDescription, new { @class = "col-sm-4 col-form-label fw-bold text-sm-end" })
	<div class="col-sm-6">
		@(Html.Kendo().TextBoxFor(model => model.FileDescription).HtmlAttributes(new { @class = "w-100" }))
	</div>
</div>

Rewritten:

@(Html.Kendo().Template()
	.AddHtml("<div class='mb-2 row required'>")
	.AddHtml(@<text>
		@Html.LabelFor(model => model.FileName, new { @class = "col-sm-4 col-form-label fw-bold text-sm-end" })
	</text>)
	.AddHtml("<div class='col-sm-6'>")
	.AddComponent(c => c.TextBoxFor(model => model.FileName).HtmlAttributes(new { @class = "w-100" }))
	.AddHtml("</div></div>")

	.AddHtml("<div class='mb-2 row'>")
	.AddHtml(@<text>
		@Html.LabelFor(model => model.FileDescription, new { @class = "col-sm-4 col-form-label fw-bold text-sm-end" })
	</text>)
	.AddHtml("<div class='col-sm-6'>")
	.AddComponent(c => c.TextBoxFor(model => model.FileDescription).HtmlAttributes(new { @class = "w-100" }))
	.AddHtml("</div></div>")
)

While this works, this markup seems much harder to read than the original. Could this be made to be simpler? Ideally I'd like to be able to drop my existing mix of html and kendo components in one method and it'd parse through to render the template properly.

Bug report

When the Grid is nested in a relatively positioned container, during the export the Grid gets an overflow style to its wrapping element. Then the style is removed and re-added again. This happens in a loop, which results in a vertical scrollbar constantly appearing and hiding.

Reproduction of the problem

1. Open this dojo example: https://dojo.telerik.com/IZoxOvOG/7
2. Click the "Export to PDF" button in the Grid's toolbar

Current behavior

Flickering caused by a scrollbar appearing and hiding

Expected/desired behavior

The Grid should remain unchanged during the export and no scrollbar should appear and hide during the export.

Environment

• Kendo UI version: 2024.3.806
• jQuery version: x.y
• Browser: [all ]

When creating columns in a TagHelper Grid definition, the Width property allows only numbers:

                                <column field="OrderID" width="100">
                                </column>

This does not match the width property in the Kendo UI and HtmlHelpers Grid definitions which allow string values to be entered as well:
https://docs.telerik.com/kendo-ui/api/javascript/ui/grid/configuration/columns.width

That way, the developer will be able to add rem and other unit values in TagHelper syntax as well.

Also, it would be convenient if there is a new property similar to this:

                                <column field="OrderID" tooltip="Unique Number of the Order">
                                </column>

                                <column field="Freight"
                                        html-attributes='new Dictionary<string, object>{ ["style"] = "width: 30rem;" }'>
                                </column>

Bug report

Grid Hidden Column is set as exportable by default for Pdf and Excel

Reproduction of the problem

1. Set a Column as hidden through the Hidden() API configuration.
2. Add both the ToolBar.Excel() and ToolBar.Pdf() API configurations.
3. Notice, that the hidden column is exported.

Current behavior

The Grid Hidden Column should be set as exportable by default for Pdf and Excel.

Expected/desired behavior

The Grid Hidden Column should not be set as exportable by default for Pdf and Excel.

Environment

• Kendo UI version: 2024.3.806
• Browser: [all]

Overview

At this stage, the ToolBar.Custom() API configuration does not expose built-in configurations for adding a handler and partial view. E.g:

        @(Html.Kendo().Grid <TelerikAspNetCoreApp455.Models.OrderViewModel>()
            .Name("grid")
            .ToolBar(toolbar => {
                toolbar.Custom().Name("Test1").ClientTemplateHandler("someHandler");
                toolbar.Custom().Name("Test2").ClientTemplateView(Html.Partial("_Test2"))
            })
            ...
        )

Current behavior

The ToolBar.Custom() API configuration does not expose built-in configurations for adding a handler and partial view.

Expected/desired behavior

The ToolBar.Custom() API configuration should expose built-in configurations for adding a handler and partial view.

### Bug report

When subscribing to the "requestStart"/"requestEnd" events of the DataSource after the Grid's initialization, the events do not fire during the Excel export.

### Reproduction of the problem

1. Enable the server operations of the Grid's DataSource.

2. Get a reference to the Grid and handle the DataSource "requestStart"/"requestEnd" events by using the bind() method.

3. Export the Grid's data to Excel through the built-in command.

4. The "requestStart"/"requestEnd" events do not trigger when the read request is activated.

A Dojo sample for reproduction: https://dojo.telerik.com/eyiDIGeM

### Expected/desired behavior

The  "requestStart"/"requestEnd" events must trigger when exporting the Grid to Excel.

### Environment

* **Kendo UI version: 2024.3.806
* **jQuery version: 3.7.0
* **Browser: all

column-command template does not access datasource as an ordinary column template.

<kendo-grid name="grid">
    <columns>
        <column field="ProductID" title="ID" />
        <column title="Column" template="#=columnTemplate(data.ProductID)#" />
        <column title="ColumnCommand">
        <commands>
            <column-command name="change" template="#=columnTemplate(data.ProductID)#"></column-command>
        </commands>
    </column>
    </columns>
    <datasource type="DataSourceTagHelperType.Custom" server-filtering="true">
        <transport>
            <read url="@Url.Action("ServerFiltering_GetProducts", "MultiSelect")" />
        </transport>
    </datasource>
</kendo-grid>

<script>
    function columnTemplate(productID) {
        if (productID % 2 == 0)
            return 'even';
        else
            return 'odd';
    }
</script>

Reproduction of the problem:
https://netcorerepl.telerik.com/myurdlbI16kA1TM213

Current behavior:
There is no way to have a dynamic template for column commands that depends on datasource.

Expected/desired behavior:
Having column-command template as column template, making it possible to access data from datasource.

Environment:
Kendo UI version: 2024.2.514

Workaround:
As an alternative solution, I'm using data-bound event, performing a for loop to all rows, but it needs to go line by line, which is not the best solution for large data.

Bug report

Reproducible with the Grid's tag helper. Works as expected in the Html helper.

Reproduction of the problem

1. Run this example: https://netcorerepl.telerik.com/QSuBQmlo123kvYQt54

Current behavior

The toolbar does not show the RadioGroup.

Expected/desired behavior

A RadioGroup should appear in the toolbar, as set in the toolbar command template:

<toolbar-command-template>
    <kendo-radiogroup name="test">
        <kendo-radiogroup-items>
            <kendo-radiogroup-item label="Factor" value="F"></kendo-radiogroup-item>
            <kendo-radiogroup-item label="Equation" value="E"></kendo-radiogroup-item>
        </kendo-radiogroup-items>
    </kendo-radiogroup>
</toolbar-command-template>

Bug report

Setting the Reoderable.Rows.ClickMoveClick() API configuration explicitly to false results in an error when using the HTML Helper wrappers.

Reproduction of the problem

1. Open the following Telerik REPL.
2. Set the Reoderable.Rows.ClickMoveClick() to false.
3. Notice the thrown client-side error.

Current behavior

Setting the Reoderable.Rows.ClickMoveClick() explicitly to false throws the following error:

Expected/desired behavior

Setting the Reoderable.Rows.ClickMoveClick() explicitly to false should not throw an error.

The "confirmation" attribute of the editable tag does not accept a string.

### Reproduction of the problem

 Add a confirmation text as a string in the "confirmation" attribute, as per the example below:

<kendo-grid name="grid">
   ...
    <editable mode="popup" confirmation="Are you sure you want to hide this invoice?" />
</kendo-grid>

A REPL sample for reproduction: https://netcorerepl.telerik.com/moEqPSFo32PrwW4d01

### Expected/desired behavior

The "confirmation" option must accept a string.

I'm using the grid with a Status Bar Template and a button component in the template.

When trying to reference the button using the data() method it returns "undefined".

I've made small changed to the Grid's "selection Aggregates" demo to show the problem:

Sample

In the sample code, when selecting a cell in the top grid, the "T" button should be enabled but the line

returns undefined.

Hi

I'm using the popup editor to edit rows in the grid.

I'm using following javascript method to open the popup:

function editSelectedRow(name) {
    var grid = $('#' + name).data('kendoGrid');
    var rows = grid.select();
    grid.editRow(rows[0]);
}

This function is called when a row is double clicked:

$("#Binders tbody").on("dblclick", "tr[role='row']", function (e) {
    editSelectedRow("Binders");
});

I have this code for many years now and it was never a problem.

With the latest version of the grid this code fails (the popup doesn't open) upon making a change in the popup window. As long as no changes is done to the record in the popup, there will not be a problem.

The error received is the following:

jquery-3.7.1.min.js:2  jQuery.Deferred exception: Cannot read properties of undefined (reading 'id') TypeError: Cannot read properties of undefined (reading 'id')

When the data in the grid is refreshed, no error will occur anymore.

HOWEVER... I also have an "Edit" button on the toolbar of the grid. That buttons uses the same 'editSelectedRow' function but when that button is used, the popup window will open, even after a change to the record!!

With other words... something goes wrong when double clicking a row after an update was made.

What has changed?

Best regards,

Peter

### Bug report

When removing a data item through the DataSource remove() method, and then trying to add a new record in the Grid, the editable row does not close when clicking the "Save" command. The Grid is set up for InLine editing. 

### Reproduction of the problem

1) Create an InLine editable Grid that binds to local data.

2) Add a custom column command that removes the respective data item by using the remove() method of the DataSource.

3) Delete a specified Grid record through the custom command.

4) Add a new record and click the built-in "Save" command.

5) The row remains in edit mode.

A Dojo sample for reproduction: https://dojo.telerik.com/IQIDuGOt

The last working version is 2024.1.130

### Expected/desired behavior

The editable row must close when clicking "Save" or "Cancel".

### Workaround

Use the Grid removeRow() method rather than the DataSource remove() method.

### Environment

* **Kendo UI version: 2024.1.319
* **jQuery version: 3.7.0
* **Browser: [all]

### Reproduction of the problem

A Dojo sample for reproduction: https://dojo.telerik.com/@gdenchev/omotILiP

### Expected/desired behavior

The new record must be visible at the top of the Grid table when the Create operation completes.

The last working version is 2024.1.130.

Grid row drag and drop capabilities enhancement request.

Currently, in order to drop a row from one Grid into another empty Grid, adding a placeholder row to the empty Grid with custom logic is required: https://demos.telerik.com/kendo-ui/grid/drag-drop

It would be nice to have a more robust drag and drop functionality that doesn't rely on custom logic to such an extent.
