Hello all,

What we can improve in this regard is to override the behavior of the ShouldRender method of the content cell. Through this we aim to re-render only content cells that have actually changed. However, there is a caveat to this approach - templated cells will still always re-render, as they accept arbitrary markup, and as such, we have no way of knowing if and when they should change(e.g. their content might be dependent on another cell content, or perhaps on something external entirely).

As for the behavior itself - a re-render is to be expected by default. Given the complex structure of the Grid, many internal components, including the content cells, accept non-primitive parameters. The default framework behavior is for such cases to always trigger a re-render. This behavior, along performance best practices, are covered in the following article: Blazor performance best practices.
