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.

Implement an option to control the columns width in scenarios that involve resizing the browser window.

Currently, if you specify the width of all the columns, on resizing the browser window the columns automatically resize proportionally. A column property MaxWidth would be nice to have, since it would prevent columns from resizing beyond a specified width value.

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

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:

* **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;
}

I use getOptions() and setOptions() to persist the state of the ajax bound grid that I have.

My toolbar is not a server one, it is this:

.ToolBar(toolbar =>toolbar.Create().HtmlAttributes(new { @class ="k-primary"}))

When I call the setOptions() method, it removes the Add button from the grid header.

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

Aligning numeric values in grids is common place and best practise.  Kendo Grid does not provide any neat functionality for this, especially in MVC where the model is strongly typed. Where a MVC grid is bound to a model, the Razor Wrapper would work better if it right aligned columns if for example type int (or other numeric types which are better to be right aligned). Where this needs not to be the case a data annotation would suit.

eg.

public class MyModel
{
   [AlignRight(false)]
   public int ProductID {get; set;}

   public int Age {get; set; } // aligned right by default in Kendo Grid because of int type
}

In the above case ProductID would be left aligned, and Age would be right (which could be the default for all integer types)

With this functionality the razor implementation could also provide an align property to override align functionality.  An AutoAlign property could provide this functionalityto auto detect from model  or not (and also allow this functionality as being off to provide backwards compatibility)

     @(Html.Kendo().Grid<MyModel>()
        .Name("grid")
        .AutoAlign(false)
        .Columns(columns =>
        {
            columns.Bound(c => c.ProductID).AlignRight(false)
            columns.Bound(c => c.Age).AlignRight(True)
        })

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();
       }

add a grid to a view

open the view with data bound to the grid.

First line of data is not selected.

Now i have to program the ondatabound property for a function which belongs to the grid component. Make it configurable for grids which do not need this feature or vice versa.

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.

Support for NullDisplayText property of the DisplayFormat metadata attribute.
