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

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; }
    }
}

1. Use the code from the incell editing docs (https://docs.telerik.com/blazor-ui/components/grid/editing/incell)and monitor the server console 
2. Edit a name (row 3 and onward)
3. Press Enter

I expect OnEdit to fire, but only OnUpdate fires

I'm getting error for dynamic Grid InCell editing. Error is displayed on editing before calling UpdateHandler. It is observed for adding new row or editing any row. 

Error: System.ArgumentException: Instance property 'x' is not defined for type 'System.Dynamic.ExpandoObject' (Parameter 'propertyName')

I was not getting this error In previous version 2.21.0 on edit of a dynamic field. Getting this error after updating to new 2.23.0 version without any code change.

Using the following code to allow the user to select rows in the grid

<GridCheckboxColumn SelectAll="true" Locked="true" />

When using the Grid Export to Excel, there is no facility for the export to only use the rows selected by the user

<GridExport>

     <GridExcelExport FileName="Export File" AllPages="@ExportAllPages" />

</GridExport>

When I lock a column that has a footer, the footer should be locked too.

Column virtualization is enabled.

Here is the scenario and how to reproduce the issue:

1. A Grid with a horizontal scrollbar. All columns have explicit widths, according to requirements.
2. The first 3 columns are locked (frozen).
3. Make the frozen columns 1 - 3 smaller. Save the Grid state.
4. Refresh the page and restore the Grid state in OnStateInit.
5. Scroll the non-frozen columns to see how the frozen columns are positioned, according to their previous larger widths. Now there are gaps between these columns.
6. The reverse issue occurs if the frozen columns are expanded in (3). Then, after state restore they overlap.

The Locked column content is misplaced, it is not matching the column header and that breaks the layout of the other columns as well.

When you scroll to right, the Locked column should stick to the leftmost side of the Grid . However, at some point its content is even missing.

I want to use a multi-checkbox filter with ExpandoObject in Grid.

It looks like the built-in validation does not respect clearing the edit item through state.  If you remove invalid edit item through Grid State, the Grid stays in edit mode and the OnRowClick stops firing.

The case is similar when you try to clear an invalid InsertedItem through the Grid State - the Grid probably stays in Insert mode and some events are not firing (for example CUD events).

Irrespective of the grid 'grouping' technique (manual or via AutoStateInit), the <NoDataTemplate> is not displaying correctly.

All other grids that are not using Grouped columns all format correctly (when no results available).

If a Grid column is bound to a nullable bool field and some of the data source records have null values for that field they are not displayed, the Grid cells appear empty.

It would be nice if the Grid displays some text for the null values, for example just "null".

We are getting a problem with grid functionality after upgrading from 2.25 to 2.26. I have attached a test project. To see the problem:

• Run the attached solution
• Click on the "Tree List" menu item
• You will then see a grid at the top of the page
• On the first row, click into the text cell under "Column 2" (to the right)
• Now click into the next cell over at "Column 3"
• Now click again into that same cell
• You get the crash

We did not have this problem before version 2.26.

Just another note on this.

It appears that the presence of the checkbox columns causes the problem. Removing the checkbox columns causes the grid to work fine. Just having one checkbox template column in the grid causes the strange crash behavior in 2.26. Before 2.26, we had no problems with the checkbox templates impacting behavior.

Hi,

Is it possible to use ENTER key to validate a popup filter ? instead of mouse.

Use a shortcut to open filter pop of focused column (cell). Ctrl+F or Ctrl+F3...

Yours,
