Hi Eric,
With the HTMLUI control, the user can access all the html elements in the document.
My suggestion in appending a text to the HTMLUI control is to append the text to the body element of the html document displayed in the control. This can be done as follows,
[C#]
//Gets the body tag element in the document displayed in the HTMLUI control
IHTMLElement bodyelement = this.htmluiControl1.Document.RenderRoot;
//Appends text to the body tag element
bodyelement.InnerHTML += "This is a sample text to append to the body element
";
Please refer the sample attached below that adds text to the HTMLUI control display as suggested above. Please try this and let me know if this helps.
Thank you,
Nanda
