#Remarks
The following code snippet inserts the content of the C:\Temp\html-content.html
file into a Rich Text Editor’s sub-document starting at the fifth character:
<DxRichEdit @ref="@richEdit"/>
@code {
DxRichEdit richEdit { get; set; }
string htmlContent { get; set; }
string pathHtml { get; set; } = @"C:\Temp\html-content.html";
protected async override Task OnAfterRenderAsync(bool firstRender) {
if (firstRender) {
htmlContent = File.ReadAllText(pathHtml);
await richEdit.DocumentAPI.AddHtmlAsync(5, htmlContent);
}
await base.OnAfterRenderAsync(firstRender);
}
}
To parse HTML code and insert the corresponding content at the end of a sub-document, use the AddHtmlAsync(String, CancellationToken) method.
