 * Loading content on demand (such as a cell value) should be done through a nested component and its `OnParemetersSetAsync` method. A similar example is available in the [load tooltip content on demand](https://github.com/telerik/blazor-ui/tree/master/tooltip/in-grid) and [load hierarchy data on demand](https://github.com/telerik/blazor-ui/tree/master/grid/load-on-demand-hierarchy) sample projects.
