Rule ID | BL0005 |
Category | Usage |
Fix is breaking or non-breaking | Non-breaking |
Cause
A property on a type deriving from ComponentBase annotated with [Parameter]
is being assigned to from outside the component.
Rule description
Component parameters should be assigned to as part of the component initialization or as part of SetParametersAsync
. Assigning a value to a parameter from an external source results in the value being overwritten the next time the component renders.
How to fix violations
Consider using a distinct property to receive values from other components. Additional code can then be written to decide which of the two values to use in the component.
When to suppress warnings
Do not suppress a warning from this rule.
