Remarks

Use the ValidationMessagePosition property to change the position of a validation message that the editor displays on invalid user input.

Example

The following code snippet validates user input in the MarkupChanged event handler and configures validation settings as follows:

• Displays a validation message if the editor’s markup is empty.
• Sets the validation message text.
• Positions the validation message at the right editor edge.

Razor

<DxHtmlEditor Markup="@markup"
              IsValid="@isValid"
              ValidationMessage="Empty markup."
              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);
    }
}
