I have a custom plugin which has a table with rows. I have Add button to add a row. While adding I want to ensure uniqueness of a property value. By default childView.Properties.Add has IsRequired = false/true but there is nothing to check if the value is unique.

Please can someone help me on this?

  • you need to look into IValidateEntityPipeline and PlugIn.Validation.PolicySet-1.0.0.json. you might need to do customization based on your requirements. Commented Aug 12, 2019 at 14:51

Have a look at validationError in DoActionAddBrandBlock.cs.
