Property Value

Type	Default	Description
Boolean	true

true to display validation icons; otherwise, false.

Remarks

DevExpress input editors support data validation. You can add editors to the Blazor’s standard EditForm. This form validates user input based on data annotation attributes defined in a model.

Data editors can display validation icons and colored outlines based on validation results. Editors with default settings display red outlines and error icons when validation fails. However, you can use the following properties to change how editors display their validation status:

The ShowValidationIcon global property - Specifies whether Blazor editors should show validation icons - error or success .
The ShowValidationSuccessState global property - Specifies whether Blazor editors should indicate the validation success status: become marked with green outlines and shows a success icon .

Note

The ShowValidationIcon option affects only standalone editors. It does not affect auto-generated editors displayed in DxGrid and DxTreeList rows/cells.
When ShowValidationSuccessState is true and ShowValidationIcon is false, only green outlines indicate the success status.
You can also specify ShowValidationSuccessState and ShowValidationIcon properties for each editor individually.

You can specify the ShowValidationIcon global option in a few different ways:

Call the AddDevExpressBlazor(IServiceCollection, Action<GlobalOptions>) method.
Call the services.Configure method that registers a configuration instance with the specified global option’s value.
Define the global option’s value in the appsettings.json file.
