Update to latest Version 21.2.52 broke IgbDataGrid

After update to Version 21.2.52 can't load IgbDataGrid.

The same source code with a previous Version 21.2.1 works without problems.

Error stack trace:

Error: System.InvalidOperationException: Unable to set property 'DataSource' on object of type 'IgniteUI.Blazor.Controls.IgbDataGrid'. The error was: Object reference not set to an instance of an object.

 ---> System.NullReferenceException: Object reference not set to an instance of an object.

Hello Karl,

I have been investigating into the behavior you are seeing, but I am unable to reproduce this at the moment. On my end, the IgbDataGrid is working normally against 21.2.52.

My tests were made against our samples browser that has been updated to version 21.2.52 of the Ignite UI for Blazor toolset. I am attaching a sample project from that browser that binds the data source to a local source. If you could please modify this sample or provide an isolated one of your own that reproduces the behavior you are seeing, I will gladly take a look.

Please let me know if you have any other questions or concerns on this matter.

Thanks Andrew, your example works for me too.

In my project I'm using Blazor.Server and .NET5.0 Maybe it's because of the configuration.

Hello Karl,

I am attaching a Blazor Server application running against .NET 5 and version 21.2.52 of our controls. This sample is also working normally on my end. Do you have any sort of special configuration going on with the sample that you are using?

Please let me know if you have any other questions or concerns on this matter.
