Hey @ElderJames I think we should rename the OnClearClick event to OnClear to be consistent with OnOk. Or OnOk to OnOkClick? It's OnOk in the original ant.design. What do you think?

We align with ant.design

@Alexbits Thank you! But I think we need to keep the old parameter for several release.And please change the target branch to feature.

@ElderJames Changed to feature. Should I rename OnClear back to OnClearClick?

[ElderJames]

No, just keep it and add the [Obsolete] attribute.
