@ice6 It will take some time to refactor this component for performance

[ice6]

@ArgoZhang just a feature request, task your time, no rush.

[ArgoZhang]

@ice6 add OnKeyUpAsync parameter and support OnEnterAsync OnEscAsync

[ice6]

@ArgoZhang yeah, the implement will have performance issue in Blazor Server mode, but it is ok to have it.

In my Blazor Server project, for performance reason, I use js module directly, communicate with server side when needed.

@ice6 support OnEnterAsync OnEscAsync feature please track issue #5356
