Bug report

A hidden template column that is not included in the ColumnMenu appears after showing another column

Reproduction of the problem

• Use the following declaration for the columns:

              .Columns(columns =>
              {
                  //Hidden template column
                  columns.Template(x =>
                  {
                      int rptIndex = Model.IndexOf(x);
                      string namePrefix = "Grid[" + rptIndex + "].";
                      Html.Hidden(namePrefix + "Id", x.Id, new { @readonly = "readonly" });
                      Html.Hidden(namePrefix + "Name", x.Name, new { @readonly = "readonly" });
                  }).Hidden().IncludeInMenu(false);

                  columns.Bound(x => x.Id).Width(120).Hidden(true);
                  columns.Bound(x => x.Name).Width(200);
                  columns.Bound(x => x.ReportingDateOriginal).Width(500).HtmlAttributes(new { id = "reporting-date-original" })
                    .Filterable(f => f.UI(GridFilterUIRole.DateTimePicker).Cell(c => c.Template("dateFilter")));
                  columns.Bound(x => x.Test1).Width(200).Hidden(true);
                  columns.Bound(x => x.TimezoneOffset).Width(200).HtmlAttributes(new { id = "reporting-date-offset" });
                  columns.Bound(x => x.Test2).Width(200).Hidden(true);
                  columns.Bound(x => x.ReportingDateAdjusted).Width(500).HtmlAttributes(new { id = "reporting-date-adjusted" })
                    .Filterable(f => f.UI(GridFilterUIRole.DateTimePicker).Cell(c => c.Template("dateFilter")));
                  columns.Bound(x => x.Test3).Width(200);
                  columns.Bound(x => x.Test4).Width(200).Hidden(true);
                  columns.Bound(x => x.Test5).Width(200);
              })

• Show the Id column

Current behavior

The first time instead of the Id, the template column appears.

Expected/desired behavior

The Id column should appear and the template column should remain hidden.

Environment

Bug report

The rendering (structure and order of elements) of the th element of a column, for which a HeaderTemplate is set, does not match the Kendo UI Grid's rendering in a similar scenario. Prerequisites: HeaderTemplate, Sortable, Filterable enabled. For more context, see Ticket ID: 1639834.

Reproduction of the problem

Check the rendering of the header of the second column:

@(Html.Kendo().Grid<TelerikMvcApp1.Models.OrderViewModel>()
    .Name("grid2")
    .Columns(columns => {
        columns.Bound(p => p.OrderID).Filterable(false).Width(100);
        columns.Bound(p => p.Freight).HeaderTemplate("<span class='k-link'>My Template</span>");
        columns.Bound(p => p.OrderDate).Format("{0:MM/dd/yyyy}").Width(140);
        columns.Bound(p => p.ShipName);
        columns.Bound(p => p.ShipCity).Width(150);
    })
    .Sortable()
    .Filterable()
    .Pageable()
    .Scrollable()
    .HtmlAttributes(new { style = "height:430px;" })
    .DataSource(dataSource => dataSource
        .Ajax()
        .PageSize(20)
        .Read(read => read.Action("Orders_Read", "Grid"))
     )
)

Current behavior

The content of the th is the following:

<a aria-hidden="true" class="k-grid-filter-menu k-grid-header-menu">
    ...
</a>
<span class="k-link">
    ...
</span>

Expected/desired behavior

The th content should be rendered as follows:

<span class='k-cell-inner'>
    <span class='k-link'>
        ...
    </span>
    <a aria-hidden='true' class='k-grid-filter-menu k-grid-header-menu'>
        ...
    </a>
</span>

It should match the Kendo UI Grid's rendering: https://dojo.telerik.com/oTalIGir/8

Bug report

The attributes handler overload does not get executed when the column is initially marked as hidden.

Reproduction of the problem

1. Open the following dojo.
2. Change the hidden property of the ContactTitle field to true.

Current behavior

The attributes handler is not executed when the column is hidden.

Expected/desired behavior

Bug report

When the scrollable option is disabled, on resizing the browser window by making it more narrow, at certain point the columns stop resizing and the whole table goes out of the right border of the Grid. Reproducible with the SASS and LESS themes.

Reproduction of the problem

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

1. Either resize the right pane or use Fullscreen and resize the browser window and make it narrower.

Current behavior

The table goes out of wrapping element (.k-grid).

Expected/desired behavior

The columns resize and the table remains within the borders of the Grid.

Environment

• Kendo UI version: 2023.1.117

Bug report

When the Grid AutoBind() configuration is set to false, the Grid is rendering an empty cell in the row element with class .k-no-data. (Image.png)

Reproduction of the problem

Set AutoBind configuration of Telerik UI for Asp.Net MVC Grid to 'false'. The Grid is rendered correctly except for the empty row and the empty cell in the table body.

Current behavior

An empty row with one empty cell is rendered.

Expected/desired behavior

The tbody element should be empty.

Environment

• Kendo UI version: 2022.2.621
• Browser: [all]

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!

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 "%".

Bug report

When the Kendo UI Grid is configured to have endless scrolling and an item is updated on the first page, the scrollbar is reset. If an update is done on a page after the first one, the scroll is correctly persisted.

Reproduction of the problem

1. Set a grid with an endless scroll.

2. Scroll down (without entering the second page).

3. Update an item on the first page.

4. The scroll is reset.

Dojo sample for reference:

https://dojo.telerik.com/EcUKIrAK

Environment

* **Kendo UI version:** 2021.1.330
* **jQuery version:** 1.12.4
* **Browser:** [all]

A recent update has revealed some strange behaviour in some (not all) grids. In the attached screenshot, the javascript for the two buttons is on display inside the toolbar. If I move them out of the toolbar, the script no longer displays.

As a workaround, I have added this to CSS:

script {
	display: none !important;
}

Bug report

When there are 3 levels of filter nesting in the URL clearing of a filter does not apply

Reproduction of the problem

1. Go to https://demos.telerik.com/aspnet-mvc/grid/serverbinding

2. On “Product Name” column apply filter “Contains” with value “a”
3. On “Unit Price” column apply filter “Is greater than” with value “1”
4. On “Units In Stock” column apply filter “Is greater than” with value “1”
5. On “Product ID” column apply filter “Is greater than” with value “1”
6. Clear the filter on “Product Name” column

Expected result: no more filter on “Product Name” column
Actual result: “Product Name” column still has a filter

A workaround is provided in the following Dojo:

FIltering a string field in the Grid with Contains operators and value null throws an error
Reported in 1492459

Current behavior
FIltering a string field in the Grid with Contains operators and value null throws an error

Bug Report

When endless scrolling is implemented, manual DataSource operations using the DataSource APIs(query, page, sort, etc.) do not work as expected.  The endless scrolling settings are causing paging issues.  

Reproduction of the problem

1. Visit this Kendo UI Dojo.
2. Scroll to 40.
3. Click the Reset Filter button.

Current Behavior

The first page is only accessible, and when scrolling down the reads continue to occur.

Expected/desired behavior

The endless scrolling settings should not interfere with manual dataSource operations.

Workarounds

1. Solution when read is called, the Kendo UI Grid will reset to its original state(dojo). 
   

       kendo.ui.Pager.fn._refreshClick = function (e) {
           e.preventDefault();
           var grid = $("#grid").getKendoGrid();
           grid.dataSource.options.endless = null;
         	grid._endlessPageSize = 20;
         	grid.dataSource.pageSize(20);
       }

2. Solution which overrides the data(dojo).
   

       kendo.ui.Pager.fn._refreshClick = function (e) {
           e.preventDefault();
           var grid = $("#grid").getKendoGrid();
           window.restoreScroll = true;
           window.scolledValue = grid.content[0].scrollTop;
           grid.dataSource._data.empty();
           grid.dataSource._pristineData = [];
           grid.dataSource.read();
       }

We are using the Kendo UI for different components like Grid in our APS.Net MVC application. Currently we are experiencing an issue while exporting the Kendo grid to Excel from mobile (both android and ios). It shows the following warning message. The same works when exporting from a PC without any issue. Could you please help to resolve the issue.
