Are there any plans to have the datagrid be both groupable and draggable?

Thanks,

Andy

I noticed after debugging a problem when editing some rather complex rows in a grid that the grid internally calls Telerik.Blazor.Extensions.ObjectExtensions.Clone(...) to create a deep clone for editing. If the object being cloned implements System.ICloneable then this is ignored and an attempt is made to clone it using reflection - the problem is that ObjectExtensions.Clone(...) fails for a number of cases and observing ICloneable would give a developer the means to implement the correct cloning behaviour.

I'm not asking for ObjectExtensions.Clone(...) to be fixed in any way (after all, no matter what you do there will always be some cases it cannot handle), just to use ICloneable where possible.

As an aside, the failed cases were:

• object has an indexer with get/set (exception thrown by ObjectExtensions.Clone() because it attempts to read the value without passing an index)
• object implements IEnumerable, including arrays (original object returned without being cloned)
• object contains a circular reference (stack overflow)

Until version 6.0 it was possible to set the Grid PageSize to "All" by setting it to the total item count. This workaround no longer works.

Please enhance the API to allow setting an "All" page size with code or initially.

Hello,

Please consider Grid data binding support for ImmutableArray. Currently, it crashes when the Grid tries to retrieve the total items count at:

Data.AsQueryable().Count();

Immutable*<T> classes are popular in state libraries.

Currently, the possible workarounds are:

• Execute .ToArray() on the ImmutableArray and bind the Grid to the new array.
• Bind the Grid to IReadOnlyCollection.

Hi,

Please lunch your demo on mobile, and try resizing a column it is very hard or impossible to do it.

Isn't possible to make resizing more pixel sensible around the separator for instance 10 pixels, and add AUTO FIT column/columns in column menu.  

Best regards,

For example, when I have two levels of grouping, I want to render only the inner footer templates, but not the outer.

While this is possible with some CSS like the snippet below, this does not scale well, and does not work well for arbitrary number of groups

<style>
    .k-group-footer + .k-group-footer {
       display:none;
    }
</style>

Group by the Vacation and Team columns to see the effect

<TelerikGrid Data=@GridData Groupable="true" Pageable="true">
    <GridColumns>
        <GridColumn Field=@nameof(Employee.Name) Groupable="false" />
        <GridColumn Field=@nameof(Employee.Team) Title="Team">
            <GroupFooterTemplate>
                Team group footer
            </GroupFooterTemplate>
        </GridColumn>
        <GridColumn Field=@nameof(Employee.IsOnLeave) Title="On Vacation">
            <GroupFooterTemplate>
                IsOnLeave group footer
            </GroupFooterTemplate>
            </GridColumn>
    </GridColumns>
</TelerikGrid>

@code {
    public List<Employee> GridData { get; set; }

    protected override void OnInitialized()
    {
        GridData = new List<Employee>();
        var rand = new Random();
        for (int i = 0; i < 15; i++)
        {
            GridData.Add(new Employee()
            {
                EmployeeId = i,
                Name = "Employee " + i.ToString(),
                Team = "Team " + i % 3,
                IsOnLeave = i % 2 == 0
            });
        }
    }

    public class Employee
    {
        public int EmployeeId { get; set; }
        public string Name { get; set; }
        public string Team { get; set; }
        public bool IsOnLeave { get; set; }
    }
}

Currently, when you open a ColumnMenu, to expand its SubMenus (for example, Filter, Column chooser) you need to additionally click on the corresponding button.

I'd like to have these SubMenus initially expanded when the ColumnMenu is opened.

I am using a ui framework that has some elements on the body with z-indexes > 1000. Eg a side menu. I am using the Telerik Grid. The Column Menus use the animation container, and because the animation containers get placed directly on the body with a z-index of 2, they always appear behind this side menu.

I want to be able to set a CSS to the main wrapping element of the Column Menu (<div class="k-animation-container>), so I can specifically set the z-index for only Column Menu instances of the animation container. 

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. 

Currently, if I call Grid.AutoFitAllColumnsAsync "too early" it throws a null reference exception.

I am aware that this is a limitation but the behavior can be improved. For example, handle the exception and provide some useful information or give me a programmatic way to know if it's too early to call autofit.

I am using Telerik Grid in our project and I have enabled the feature Reorderable="true". At GridColumnMenuSettings I am getting the following options:

Set column position :

• Move Next 
• Move Previous

Those options are commonly showing for all columns but I want to disable "Move Next" option for the last column and "Move Previous" option for the first column as these options are not applicable to the corresponding columns.
