I need to know which cell the user right clicked on so I can adjust my context menu. I need the cell value, the row model and the field of the column.

The following KB article shows a solution you can use immediately: https://docs.telerik.com/blazor-ui/knowledge-base/grid-which-cell-context-menu.

My grid starts with Groupable=false and at some point I may need to make it groupable. The group panel appears, but I cannot drag the column headers to it to actually group.

---

ADMIN EDIT

A workaround is to hide the grid so it can re-initialize with the new groupable setting:

Is Groupable: @IsGroupable
<TelerikButton OnClick="@ToggleGroupable">Toggle Groupable</TelerikButton>

@if (isGridVisible)
{
    <TelerikGrid Data=@GridData @ref="@GridRef" Groupable="@IsGroupable" Pageable="true" Height="400px">
        <GridColumns>
            <GridColumn Field=@nameof(Employee.Name) Groupable="false" />
            <GridColumn Field=@nameof(Employee.Team) Title="Team" />
            <GridColumn Field=@nameof(Employee.IsOnLeave) Title="On Vacation" />
        </GridColumns>
    </TelerikGrid>
}

@code {
    bool IsGroupable { get; set; }
    bool isGridVisible { get; set; } = true;
    TelerikGrid<Employee> GridRef { get; set; }
    async Task ToggleGroupable()
    {
        //save state (sorting, paging,...) - it will be lost when we hide the grid
        var state = GridRef.GetState();

        //hide the grid so it can later re-initialize with the new groupable setting
        isGridVisible = false;
        await InvokeAsync(StateHasChanged);
        await Task.Delay(20);
        IsGroupable = !IsGroupable;
        isGridVisible = true;

        //afte the grid re-initialized and rendered with the new setting, restore its state
        await InvokeAsync(StateHasChanged);
        await Task.Delay(20);
        await GridRef.SetState(state);
    }


    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; }
    }
}

Hi,

Please simplify customizing Grid Popup, it should be available under Grid with build-in context and binding

I am already using your do-it-yourself example but IMHO it is too much code

Regards

Andrzej

I have a column in the grid that is bound to a enum. The enum value names show up fine in the grid, but when exported, I get the underlying int value, which is incomprehensible to the users.

Thanks

ADMIN EDIT:

As a workaround you could generate the .xlsx file yourself. I'm attaching a sample project that allows you to do that. The relevant line of code is line 125 in Index.razor

It would be really nice now that we have a grid loader, to be able to customize this using a custom template.

Currently it fixes even the animation type, so while we have chosen a different enum (Pulsing) for all our loaders, our grids now look different because it is not possible currently to change the grid loader beyond turning it on and off.

Hello,

First of all: thank you for implementing the Excel like filtering with the new CheckBox Filter! This was a feature that was highly sought after in our development team.

But there is one thing I am missing: the checkbox list has no option for sorting.

If we want to sort our filters now we have to implement the FilterMenuTemplate in every column that has filtering active (which are a lot) and define the list with filter options and filter it ourselves. 

Is this something that can be fixed easily?

---

ADMIN EDIT

We will probably sort ascending the values by default (out-of-the0box), and any other custom sorts should be implemented through the filter menu template.

---

Can you either fix the Export functionality to apply Custom footers that are not aggregated to the exported data or Change Enum options to add a Custom type to allow custom footer template values to be exported along with the other GrigAggregates?

I localize the names of my columns in the models. This works for the root-level model I bind to the grid, but using nested (navigation) properties does not let them pick up the title.

---

ADMIN EDIT

A sample project is attached that showcases the localization of the displayname attribute, and how that works for the main model. Since it does not work for the nested models, a small helper method to extract the required resource manually is added to the Title parameter of such a column.

---

It would be good to have a Grid parameter like "ExpandDetailsOnSelection" for the Grid:

-> When the user selects a row, the DetailTemplate automatically expands - the DetailTemplate of the previous selected item is automatically collapsed

Advantages:

- no "+" button needed

- easy to integrate for 2-way-binding on SelectedItems (no need to use GridState and RowClick event)

Hello everyone,

We created this Feature Request to gather feedback on the way the item expansion is working in the Grid state. Currently, you can expand any items with the ExpandedRows collection of int where you pass the indexes of the rows. 

Another option, which we are thinking of, is to provide a Collection<Model>. This would let you pass models, instead of indexes and the Grid would automatically expand those items. This approach would make the need to preserve the indexes redundant, which you should currently do when Filtering/Sorting and Grouping the items in the Grid.

We would appreciate your feedback on both approaches and which you think will be easier to use.
