I faced the problem with post secure content using RadzenFileInput in RadzenTemplateForm.
The secure files such as: .keystore, .mobileprovision, and .p12 file.
When using RadzenFileInput components. They produce Base64URI as a value. then Post these values to ASP.NET WEB API. I don't know how to save these files to server folder with the same file format and data.
Radzen Upload can use inside RadzenTemplateForm with Submit method in Submit attribute?
Another question for RadzenSteps? How can I use a custom validation in C#? if validation is false, could not move to next step. Otherwise, move to next step?
