RadzenTable validation

Radzen.Blazor Components

Hi

I have following code. Is it somehow possible to validate on submit, that at least one list entry (owner) is selected? RadzenTable does not support IsRequired.

<RadzenTemplateForm TItem="Group" Data=@group Submit=@OnSubmit InvalidSubmit=@OnInvalidSubmit>
    <RadzenTabs SelectedIndex="0" RenderMode="TabRenderMode.Client">
        <Tabs>
                <RadzenColumn Size="12" SizeSM="6">
                    <RadzenTable GridLines="DataGridGridLines.Horizontal" Style="border-left:unset; border-right:unset;">
                        <RadzenTableBody>
                            @if (Value.Owners is not null)
                            {
                                @foreach (var selectedUser in Value.Owners)
                                {
                                    <RadzenTableRow>
                                        <RadzenTableCell>
                                            <RadzenStack Orientation="Orientation.Horizontal">
                                                <RadzenText Style="width: 100%; align-content: center;"
                                                            class="rz-mb-0">@(selectedUser.DisplayName)</RadzenText>
                                                <RadzenButton Variant="Variant.Text" Icon="delete" ButtonStyle="ButtonStyle.Base"
                                                              Click=@(args => DeleteOwner(selectedUser.Id!)) />
                                            </RadzenStack>
                                        </RadzenTableCell>
                                    </RadzenTableRow>
                                }
                            }
                        </RadzenTableBody>
                    </RadzenTable>
                </RadzenColumn>
        </Tabs>
    </RadzenTabs>
</RadzenTemplateForm>

RadzenTable is not a data component but a layout one. Not related to validation in any way.

ok, thanks, and there is no way to customize such thing?

Only form components can be validated - check our demos for reference.
