Bug report

The column format applied through the .Format() option is ignored, if the column is bound to a nullable DateOnly field.

Reproduction of the problem

1. Declare a nullable DateOnly field in the view model:

public DateOnly? PaymentDate { get; set; }

2. Bind a column to the field and set its format:

columns.Bound(p => p.PaymentDate).Title("Date").Format("{0:MM/dd/yyyy}").Width(160);

Current behavior

The specified format is ignored, e.g., the Grid shows 2025-01-21, instead of 01/21/2025

Expected/desired behavior

The specified column format is applied.

### Bug report

When the Grid filter menu is customized with a DropDownList, the initial option defined by using the "index" property is not set.

### Reproduction of the problem

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

### Expected/desired behavior

The DropDownList should be initialized with an initially selected option.

### Environment

* **Kendo UI version: 2022.1.119
* **jQuery version: 1.12.4
* **Browser: [all]

Bug report

Reproduction of the problem

1. Open the following dojo.
2. Open the column menu.
3. Try to remove all columns through the checkboxes.

Current behavior

The last checkbox selection is not disabled and allows all the columns to be removed if the menu options for the command column are explicitly set to false:

Expected/desired behavior

The last checkbox selection should be disabled without allowing all the columns to be removed if the menu options for the command column are explicitly set to false:

The following dojo depicts the aforementioned behavior.

Trouble on iPad 6/7/8 with Safari.

Using grid with batch and incell edit mode.

Datepicker is not working. It just shows the text box to manually type in date.

Every once in a while the date picker pops up and stays for selection.

Sometimes I see the dat picker, but it goes away suddenly before being able to set a date.

Current configuration: server-side filtering

Desired behavior:

1. Grid searches are "anded" to any existing filters
2.  When the search box is cleared the pre-existing filters are retained

Bug report

When ParseFormats is set in the DatePicker editor used in the Grid popup, the picker does not show the field value to which it is bound.

Reproduction of the problem

1. Add a DateOnly? field to the model:

public DateOnly? OrderDate { get; set; }

2. Bind a Grid column to the field.
3. Set the default value in the DataSource:

.Model(model =>
{
    model.Id(p => p.OrderID);
    model.Field(p => p.OrderDate).DefaultValue(new DateOnly());
})

4. Configure Popup editing in the Grid.
5. Add a DateOnly.cshtml editor in EditorTemplates:

@model DateOnly?

@(Html.Kendo().DatePickerFor(m => m).ParseFormats(new string[] { "MM/dd/yyyy" }).HtmlAttributes(new { title = Html.ViewContext.ViewData.TemplateInfo.GetFullHtmlFieldName("") }))

Current behavior

When editing a record. The value of the OrderDate field is not displayed in the DatePicker.
If you remove the ParseFormats option from the DatePicker, it shows the value as expected.

Expected/desired behavior

The field value should be displayed in the picker, even when ParseFormats is set.

Bug report

When a Grid's row is reordered and then the changes are saved - a Destroy request is sent to the server for the dataItem of the reordered row. This happens even though no changes are applied to dataItem of the reordered row.

Reproduction of the problem

1. Run this Telerik REPL or this Dojo
2. Reorder a row
3. Open the browser's Network Tab
4. Click the Save Changes button

Expected/desired behavior

The Grid should request the reordered item to be perished from the backend.

Environment

• Kendo UI version: 2023.2.718

### Bug report

When the Grid is initialized in a hidden container (for example, in a non-selected tab of a TabStrip) and its initial data binding is disabled (autoBind: false), the pager information is not visible when the data is loaded afterward.

### Reproduction of the problem

1. Initialize a Grid into a non-selected tab of a TabStrip and set its autoBind option to "false".

2. Select the tab and check how the empty Grid is rendered.

3. Call the read() method of the Grid's DataSource in the browser console to request the data.

4. The data is loaded, but the pager information remains hidden.

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

### Expected/desired behavior

The pager information must be available when the data is loaded into the Grid.

### Environment

* **Kendo UI version: 2024.4.1112
* **jQuery version: 3.7.1
* **Browser: [all]

Bug report

Dynamic Grid produces a RunTimeException when the Filterable() configuration is enabled

Reproduction of the problem

1. Configure the dynamic Grid based on the following example.
2. Set the .Filterable() API configuration of the Grid.
3. Notice that the application throws a System.ArgumentNullException: Value cannot be null.

Example

@model System.Data.DataTable

@(Html.Kendo().Grid<dynamic>()
    .Name("gridItem")
    .Columns(columns =>
    {
        foreach (System.Data.DataColumn dcolumn in Model.Columns)
        {
            columns.Bound(dcolumn.ColumnName).Title(dcolumn.Caption);
        }
    })
     ...
    .Filterable()
)

The aforementioned declaration will work in the previous 2024.3.1015 version of the suite.

Current behavior

The Grid makes the application throw a runtime error.

Expected/desired behavior

The Grid makes the application should not throw a runtime error.

Environment

• Kendo UI version: 2024.4.1112
• Browser: [all]

By default, when the "paste" command is added, the default option is "insert" mode ("Paste (Insert)"). Is it possible to add an option that allows setting the default paste mode to "replace" ("Paste (Replace)")?

Bug report

In a .NET 7 project when TagHelper Grid is configured and RuntimeCompilation is employed, starting from version 2023.2.606 an unhandled exception is thrown.

Reproduction of the problem

1. Create a .NET 7 project
2. Enable RuntimeCompilation
3. Install a 2023.3.606 or later version of Telerik UI for ASP.NET Core
4. Configure a TagHelper Grid

Current behavior

When run a runtime error occurs

Expected/desired behavior

TagHelper Grid should exhibit the same behavior as HtmlHelper ones.

Environment

• Kendo UI version: 2024.1.130

Is it possible to implement template options for the "update" and "cancel" column commands of the Grid?

For example:

$("#grid").kendoGrid({
  columns: [{ 
    command: [{
        name: "edit",
        template: {
            update: "<button class='customUpdate'>Save</button>",
            cancel: "<button class='customCancel'>Cancel</button>",
          }
      }]
   }],
  ...
});

Currently, when using the default Grid search functionality and the column filter menus, we observe the following:

• When a column filter is applied first, using the Search feature afterward overrides the column filters, applying the search filter with the "contains" operator to the specified columns.
• Conversely, when a search is performed first and then followed by a column filter, the grid generally functions as expected.

However, there’s a specific scenario where this does not work properly:

• If a search is performed and then a column filter is applied to a column where the search criteria are relevant, the Grid returns no data.

For example:

• After searching for "2018," the expected columns displayed in the filters (notably, the ContractNumber is among them).

• When a column filter is subsequently applied to ContractNumber (e.g., setting it to "2018-CR0018"), the Grid removes the ContractNumber from the search filters and adds the column filter with an "AND" operator. This setup returns no data because of the search filters and the "AND" operator.

Expected Behavior and Alternative

This functionality behaves correctly in the Telerik UI for Blazor Grid component - the search and column filters are managed as separate objects.

Is it possible to enhance the Grid filtering similar to the Blazor Grid?
