On Hierarchy grids with Inline edit mode, I noticed that if a row is currently being edited and I try to expand the row to show the child grid an exception is thrown: "Error: System.InvalidOperationException: TelerikValidationComponent requires a cascading parameter of type EditContext. You can use Telerik.Blazor.Components.TelerikValidationTooltip`1[System.String] inside a EditForm or TelerikForm".
The problem stems from a validation tool inside the Grid EditorTemplate.
Hello everyone,
A possible workaround is to disable hierarchy expansion for the row in edit mode:
CSS
.k-grid-edit-row .k-hierarchy-cell {
pointer-events: none;
}
.k-grid-edit-row .k-hierarchy-cell span {
display: none;
}
Regards,
Dimo
