Exception at BaseComponent DataSource

When Syncfusion.EJ2.Blazor control adds items to Syncfusion.EJ2.Blazor.BaseComponent.DataHashTable there is a chance to cause an unhandled exception due to the fact Random.Next() will not always return a unique value; with to my testing was as few as 10 iterations given enough time and proper conditions, even fewer items may cause a key collision.  

Attached is a screenshot of the code I found to be causing the issue in my case however it looks like similar logic of using a single "Random" number to form a needed unique key is used in other locations.

If I may recommend using a Guid instead of a single random number or very least multiple random numbers to form the unique key to mitigate the chances of a collision.
