This feature request is to provide an option to configure the displayed format of the editor for the GridColumn. It is essential for the numeric and date editing. An alternative would be to follow the DisplayFormat parameter and reuse it in the DatePickers and NumericTextBox. However, we need to gather feedback for the required functionality from our customers.

Scenario

Rendering the grid column like so:

<GridColumn Visible="true" Field="ScalePercent" Title="Scale Percent" DisplayFormat="{0:P5}" VisibleInColumnChooser="false" />

The data in the grid column will show the 5 decimal precision. However, when we go in edit mode the value in the NumericTextBox is restricted to two decimal places.

Workaround

1. Usage of templates

2. Generic change of globalization setting for the NumericTextBox

`culture.NumberFormat.NumberDecimalDigits`

Currently, the validation of the grid can be disabled altogether via the GridValidationSettings.Enabled option. However, we cannot control the validation of the grid per column.

Also, we cannot control when the validation is triggered. The simple inputs expose the ValidateOn option, but it cannot be set to the default editors of the grid without the need for an explicit declaration of a custom editor.

The feature request is to be able to customize the GridCsvExportOptions and GridExcelExportOptions from the API methods -

• ExportToExcelAsync
• ExportToCsvAsync
• SaveAsExcelFileAsync
• SaveAsCsvFileAsync

It will be useful to be able to customize the columns and data to be exported.

Telerik edit:

A possible workaround is to click the built-in Grid export buttons with JavaScript. With this approach, you will be able to use the built-in export options and events. Here is a REPL example.

I am adding validation messages for the popup form fields and I do not want to display the ValidationSummary in addition to them. Please add option to remove it.

Built-in field validation messages will be exposed in future version of the product. Thus, you can add inline or tooltip validation messages to the Popup edit form without an EditorTemplate.

For the time being, you can remove the ValidationSummary with some CSS. Here is an example of hiding the ValidationSummary and adding inline ValidationMessage for the ProductName field: https://blazorrepl.telerik.com/cckycgPf37NZfy9J11

Expose GroupableSettings with an option to specify whether to render the group footer. The possible values should be always (like current implementation), or when the group is expanded. An example (just for demonstration) api would be:

```

<GridSettings>

<GridGroupableSettings Footer="@GridGroupableFooterVisible.Always | @GridGroupableFooterVisible.Expanded"></GridGroupableSettings>

</GridSettings>

```

I'd like for someone to be able to select all of the rows in a particular group. The main selection checkbox will just select all of the rows.

It would be nice if this also worked for sub grouping.

I would like to request a simple update to the Grid component.

When a column width is too small - the column header text is cut-off or is unreadable.

For example:

It would be nice that on mouse hover, the full title would be rendered. Currently to achieve this, I have to implement a custom <HeaderTemplate> for every grid column and add a span myself:

<GridColumn Field="@nameof(SalesOrderLineItem.Quantity)">
    <HeaderTemplate>
        <span title="Order Quantity">Order Quantity</span>
    </HeaderTemplate>
</GridColumn>

Can you update the GridColumn component and add a title attribute to the column <th> element so the browser can show the fill title should the user hover over it?

Allow the Grid to support Enums which are mapped to use datatypes different from int. Currently, if I try to use the following Enum, an InvlidCastException is generated:

public enum ShortEnum : short
{
    Value1,
    Value2,
    Value3
}

Does the Blazor grid have any support for any or all queries on sub-property collections? I would like to have the grid OnRead be able to generate a query against a sub-entity collection.

E.g.

GET serviceRoot/People?$filter=Emails/any(s:endswith(s, 'contoso.com'))

From what I can tell the Column.FieldName property only will generate a valid query for scalar properties. Is there any way to make this work?

Given the Northwind OData sample https://demos.telerik.com/kendo-ui/service-v4/odata. I would like to display a grid of all customers. In the grid, I would like to have a column that provides filtering for the orders shipper column as in the query below.

https://demos.telerik.com/kendo-ui/service-v4/odata/Customers?$expand=Orders&$filter=Orders/any(d: contains(d/Shipper/CompanyName,'Speedy Express'))

There does not seem to be a way for the in-built filter mechanism to use a lambda and it seems like there should be.

How can I get the tooltips for validation of each field displayed at the corresponding field in a Grid Popup form, not just the summary below the Form, etc?

---

ADMIN EDIT

This will be handled through exposing an option to set your preferred field validation message type - tooltip or inline. It will cover all edit modes (Popup, Inline, InCell).

If you want to remove the ValidationSummary after adding field validation messages, check the ability to remove ValidationSummary from the Popup edit form.

Please support Display(Order = ...) with autogenerated Grid columns.

Such functionality will also be useful for controlling the order of manually declared columns when using a custom component for reusable columns. For example: https://blazorrepl.telerik.com/cGOtbwOX21f6zQcy35 - the "Name" column is rendered last and currently one cannot control its order.

public class DateModel
{
  [Display(Order = 2)]
  public string Id { get; set; }
  [Display(Order = 1)]
  public string Text { get; set; }
}

AutoFitting all columns should not leave blank space in the Grid, the last column should take the available space.

This functionality might be triggered by a setting a bool parameter to true.
