DxHtmlEditor.MarkupChanged Event

Fires when the editor markup changes.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v24.2.dll

NuGet Package: DevExpress.Blazor

Declaration

[Parameter]
public EventCallback<string> MarkupChanged { get; set; }

Parameters

Type	Description
String	The editor markup.

Remarks

Handle the MarkupChanged event to respond to the Markup change. Note that you do not need to handle this event to update markup source when you use two-way data binding for the Markup property (@bind-Markup).

Example

The following code snippet validates user input in the MarkupChanged event handler:

<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);
    }
}
