Hi Cemil,
Greetings from Syncfusion support.
We have already raised the reported query in stack overflow ("Accessing properties in dynamically created components "), because the reported question appears to be common in Blazor platform. We will update you once we have the answer. Please find the issue details from the link.
Here we asked about the dynamic property class. When we have the answer, we can use the solution for all properties that bound to the dynamically created component.
Regards,
Sevvandhi N
