Hi, I could not figure out how to enter text into HTML Editor using Watin. I tried //ie.TextField(Find.ById("htmlDetail_ctl06_ctl04")).TypeText("ABCD"); But got error: Can't move focus to the control because it is invisible, not enabled, or of a type that does not accept the focus. Can you give some example how to enter text into AJAX HTML Editor using watin please? I am not sure what to plug in frameSrc and java script from this solution - http://stackoverflow.com/questions/939448/unit-testing-the-ms-ajax-toolkit-html-editor Here is html from Develper tool when click the text box: Thanks in advance
