Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v25.1.dll

NuGet Package: DevExpress.Blazor

Declaration

[DefaultValue(true)]
[Parameter]
public bool ShowValidationMessageOnFocus { get; set; }

Property Value

Type	Default	Description
Boolean	true	true to hide a validation message after the editor loses focus; otherwise, false.

Remarks

<DxHtmlEditor> allows you to validate user input. To specify validation rules, use the IsValid property.

When a user enters an invalid value, the focused editor displays a validation message at the specified position. After the editor loses focus, it hides the validation message. Disable the ShowValidationMessageOnFocus property to change this behavior.

<DxHtmlEditor Markup="@markup"
              IsValid="@isValid"
              ValidationMessage="Empty markup."
              ShowValidationMessageOnFocus="false"
              ValidationMessagePosition="HtmlEditorValidationMessagePosition.Right"
              MarkupChanged="@OnMarkupChanged"
              Height="100px"
              Width="80%" />

@code {
    bool isValid;
    string markup { get; set; } = "";
    void OnMarkupChanged(string newValue) {
        markup = newValue;
        isValid = !string.IsNullOrEmpty(newValue);
    }
}
