Iframe Editable in Blazor RichTextEditor
17 Aug 20233 minutes to read
When the RichTextEditorIframeSettings
option is set to RichTextEditorIframeSettings.enabled, the editor creates the iframe element as the content area on component initialization, which is used to display and edit the content. The editor only displays the body tag of an <iframe>
document in the content area.
Basically, in an iframe mode, you have the entire document but only the editor content, and you can also use styles and scripts only for the particular editor.
@using Syncfusion.Blazor.RichTextEditor
<SfRichTextEditor>
<RichTextEditorIFrameSettings Enable="true" />
<p>The Rich Text Editor component is WYSIWYG ('what you see is what you get') editor that provides the best user experience to create and update the content. Users can format their content using standard toolbar commands.</p>
</SfRichTextEditor>
IFrame attributes
You can add an additional attribute to the body tag of an <iframe>
element by using the RichTextEditorIframeSettings.Attributes property. This property contains name or value pairs in string format. It is used to override the default appearance of the content area.
@using Syncfusion.Blazor.RichTextEditor
<SfRichTextEditor>
<RichTextEditorIFrameSettings Enable="true" Attributes="@IframeAttributes" />

</SfRichTextEditor>
@code {
private Dictionary<string, object> IframeAttributes = new Dictionary<string, object>() {
{ "style", "background: lightgray;" }
};
}
Adding external CSS/Script file
The editor offers to add an external CSS file to style the <iframe>
element. Using the RichTextEditorIframeSettings.Resources property, you can easily change the appearance of the editor’s content by using an external CSS file.
Similarly, add the external script file to the <iframe>
element using the RichTextEditorIframeSettings.Resources
property, and it will provide the additional functionalities to the Rich Text Editor.
@using Syncfusion.Blazor.RichTextEditor
<SfRichTextEditor>
<RichTextEditorIFrameSettings Enable="true" Resources="@Resources" />
