LabelToLinklinkLink to this section

Returns the name whose label the client should link to the component, or null when no label should be linked, and records the link as done so that a later ElementReference) talks to the client only when Name or Visible change again. Components that already create client-side state after render pass the result to that call instead of making a separate one.

Declaration

protected string LabelToLink()

Returns

LinkLabelAsynclinkLink to this section

Asks the client to point aria-labelledby of element at the label whose for attribute targets Name. Call it from OnAfterRenderAsync; it talks to the client only when Name or Visible changed since the last call. Use it for components whose focusable element is not labelable, so a RadzenLabel or a plain label associated through the name names it anyway.

Declaration

protected Task LinkLabelAsync(ElementReference element)

Parameters

Returns

NotifyFieldChangedlinkLink to this section

Notifies the EditContext that the field has changed while validators observe the specified value. The stored value is restored afterwards so that two-way binding parameter re-flow keeps working as expected.
