Hi monaliza17,
<o:p></o:p>
uring a full postback (i.e. if (!IsPostBack)), the webpage loses CSS for 3-4 seconds while the page is loading.
If you do not want to show the dropdownlist <select>
before bootstrap css styles apply to it, you can try to hide that dropdownlist in default, and set short time delay (using
setTimeout() method) to show that dropdownlist. <o:p></o:p>
With Regards, <o:p></o:p>
