    In my solution I’m using the unbound grid. I have a dataset, that I input to the grid with around 200k rows, and the grid won’t load because if the time it takes to build it. Is there a solution to this problem.

    I have attached some code that can trigger my problem.

    Here is the update from the developer:

    There is a high workload task executed under Blazor app. CPU-intensive work and unbounded growing list of items results to performance issues.

    Based on documentation:

    Thus, FlexGrid is not a reason of the performance issue (and it could be proved if you woudl try to add items into List).

    If the data is coming from a big dataset the best solution is to assign that data-set to the grid, through the ItemsSource property. In bound-mode the grid will delay the creation of the rows and will load much faster.
