c# - Selenium WebDriver with RadWindow -

i attempting access form within radwindow. web page uses window.radopen() generate asp.net popup. need access popup, edit it, , click button. there way using selenium webdriver?

specifically, radwindow contains textarea id of "txtentries" , button , id of "btnaccept". have tried finding textarea first, below, no luck.

i attempting:

state = wait.until<iwebelement>((d) =>             {                 return d.findelement(by.cssselector("div#radwindow #txtentries"));             }); 

with failed results.

yea, there's way.. since radwindow not actual window, makes easier.

first, use css , have parent selector. like,

div#radwindow 

then add elements want find that. e.g.

input[type='text'].someclass 

then concatenate them, turns -

div#radwindow input[type='text'].someclass 

which translates in css "first find div id radwindow, , find input descendant of div, type attribute equals text has someclass attached.
