The keyboard navigation built into the Wizard control conflicts with DatePicker. When I used the up down arrows to change the date it causes the wizard to move to the next page.
I am able to reproduce this same issue right on the demo page Blazor Wizard Demos - Overview | Telerik UI for Blazor
Steps to Reproduce.
1. Complete the required password.
2. select the date field and use the up down arrow keys.
I'm not aware of any workaround since we cannot disable keyboard navigation on the Wizard control.
