  Hello,
  
  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.

  Hi,
  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:
  
  https://docs.microsoft.com/nb-NO/aspnet/core/blazor/security/server/threat-mitigation?view=aspnetcore-6.0#cpu
  
  https://docs.microsoft.com/nb-NO/aspnet/core/blazor/security/server/threat-mitigation?view=aspnetcore-6.0#memory
  
  Thus, FlexGrid is not a reason of the performance issue (and it could be proved if you woudl try to add items into List<Tupple>).

  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.
